Poor 0.1% low frametimes on CF390 (and SLI, though not as bad). A higher transistor count generally indicates a newer, more powerful processor. The R9 390 has a 5% higher stock GPU clock, and a substantial stock memory clock increase of 20%. This is especially true for the 390s, where performance seems to indicate that there's no CF scaling at all with the Devil 13. SLI and CrossFire are also historically prone to micro-stuttering as a result of their dual-processing technique (normally AFR, or alternate frame rendering). The game has since released major patches which affected performance on nVidia and AMD devices, but most heavily on the AMD side. Nvidia GeForce GTX 960 $ 289. 2.51 TFLOPS higher floating-point performance? The GPU connected to the display manages the sync technology. Overclocking won't be tested until the review. This issue presents itself to some degree in a few other games, but is most notable in Fallout 4. Performance analysis is accompanied by power draw and thermal tests, though a proper, full review on the Devil 13 card will follow this content in short order. The number of pixels that can be rendered to the screen every second. Here's where we start seeing differentiating stats. Intro The GeForce GTX 970 has a GPU core speed of 1050 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 256-bit bus. 970 has better low frametimes at lower resolutions, but falls hard at 4K. As fake as can be likely as the source shows results of the AMD R9 390X, Nvidia GTX 980 Ti and Titan X. All other game settings are defined in respective game benchmarks, which we publish separately from GPU reviews. The card runs for $600 – similarly priced to dual-GTX 970s (ranging from ~$620-$660) – but has a pretty massive $100 MIR right now. GamersNexus.net is Owned, Operated, & Maintained by GamersNexus, LLC. Editorial & Testing: Steve “Lelldorianx” BurkeVideo & Video Editing: Keegan “HornetSting” Gallick, Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. The average user will not detect the FPS difference between these two solutions. If you get 2.25x times the frame rate at 720p vs 1080p then the GPU is performing .... 28 Mar 2017 ... Mass Effect: Andromeda 4K Benchmark: 1080 Ti vs. GTX 1080 ... Andromeda . Radeon R9 390X competes with GTX 980 performance. Based on 664,692 user benchmarks for the AMD R9 390X and the Nvidia GTX 970, we rank them both on effective speed and value for money against the best 652 GPUs. First world problems. The results in the tables are averages of these three runs. We tested these two graphic cards on these following games: Counter Strike Global Offensive, Player Unknown’s Battlegrounds, Grand Theft Auto V, League of Legends, Overwatch, … It is an important factor of memory performance, and therefore the general performance of the graphics card. We don't objectively measure dBA output (though may begin soon), but can subjectively state that the Devil 13 is the loudest card we've ever tested. Intro The GeForce GTX 970 uses a 28 nm design. We mostly saw differences centered around the 1.87% to 2.5% area. Allows you to view in 3D (if you have a 3D display and glasses). We tested using our 2015 multi-GPU test bench. Like all R9 390X cards, the MSI R9 390X GAMING is equipped with 8 GB of video memory. The PCS Dual R9 390 card puts the peak system load up to 582.73W, compared against the SLI GTX 970 power draw of 411.72W. We execute an in-house automated script to ensure identical start and end times for the test. I also had people who were typing apostrophes into the address bar - sigh. Adjust PSU purchases appropriately. QHD is where the Radeon R9 390X really shines, though. It has higher clock speed compare to its predecessor the R9 290X. This allows you to configure multiple monitors in order to create a more immersive gaming experience, such as having a wider field of view. Newer versions introduce more functionality and better performance. AMD Radeon R9 390X vs Nvidia Geforce GTX 1660 Super. Some apps use OpenCL to apply the power of the graphics processing unit (GPU) for non-graphical computing. The cards operate about 1C apart – but that's pretty useless for shoppers of CrossFire configurations, since the thermals will hinge entirely upon which two cards you buy. Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. Our advice is to look over the charts relevant to your gaming, read the accompanying text, and determine what's best for you. The graphics processing unit (GPU) has a higher clock speed. Once a failure was provoked or instability found -- either through flickering / artifacts or through a driver failure -- we stepped-down the OC and ran a 30-minute endurance test using 3DMark's FireStrike Extreme on loop (GFX test 2). The 2x R9 390s run a bit worse. The thermal measurement is only useful in scenarios where the Devil 13 is considered. The data was included above because it was confidently collected, but from a user standpoint, ACS would have been unplayable in our tested configuration for the Devil 13. Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display. Each game was tested for 30 seconds in an identical scenario, then repeated three times for parity. Do note that running two R9 390s will draw substantially more power than two 970s (and more still than a single Fury X or 980 Ti). This game is one where Nvidia's GeForce GTX 970 outperforms the R9 390, matching the Devil at its factory clock rates. Thermals and power draw were both measured using our secondary test bench, which we reserve for this purpose. All games were run at presets defined in their respective charts. Thermals, power, and overclocking were all conducted on the Z97 bench above. Oct 25, 2019; 4 min read; R9 390x Vs Gtx 970 At 1080p Resolution Micro-sutter is observable as a result of disparate frame-time gaps, where the time between frame renders is inconsistent enough that the user can perceive a jarring difference – e.g. As such, both the 390X and even a theoretically price-matched GTX 980 are both bad leaps upward and should be … ... Small semiconductors provide better performance and reduced power consumption. Overclocking was performed incrementally using MSI Afterburner. Our experience with Just Cause 3 has been disappointing for multi-card setups. Yes - pushes into 144Hz range, desirable for competitive FPS. MSI's Radeon R9 390X GAMING comes with a massive triple-slot, dual-fan cooler that turns its fans off completely when the card idles. The short answer, as we declared in the “SLI 970s or 980 Ti?” article, is “it depends.” It is still safer to trend towards similarly-priced single-GPU configurations; such a purchase avoids buyer's remorse in situations like those generated by Just Cause 3, where scalability may as well not exist. This is the maximum rate that data can be read from or stored into memory. Gtx 970 or R9 390X ... By setting the performance to maximum in the power settings, and some sane gfx settings, I can get around 20-30fps without major sacrifices to ARK's presentation. There is effectively no perceptible difference in AVG FPS metrics. In the event of the first scenario – where the user already owns one GTX 970 and is considering a second – the value considerations are different and will be discussed only in the conclusion. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. Allows you to connect to a display using DisplayPort. Over in Asia a handful of benchmarks leaked. The memory clock speed is one aspect that determines the memory bandwidth. Home > Graphics card comparison > AMD Radeon R9 390X vs Nvidia GeForce GTX 960. The CF 390s finally pull ahead in Shadow of Mordor, leading the SLI 970s by 4.7% at 1080 (130 vs. 124FPS AVG) and 4.1% at 1440p (100FPS vs. 96FPS AVG). Performance Issue AMD R9 390X. No overclocking was applied during these tests, which does mean that the slower of the two cards (the 970 Hybrid, at 1140MHz) will marginally impact the overall performance. A small form factor allows more transistors to fit on a chip, therefore increasing its performance. No reasonable SLI or CF scaling in JC3 at this time. Using more than one GPU in parallel can give increased performance. The new AMD R9 390 is the direct successor to the R9 290. GeForce GTX 970 vs Radeon R9 390X 8G. FPS benchmarks look at performance of 2x CrossFire R9 390s vs. 2x SLI GTX 970s, including supporting data from a GTX 980 Ti, 980, and R9 390X. AMD Radeon R9 390X. 5.91 TFLOPS vs 3.4 TFLOPS The GDDR5 RAM runs at a frequency of 1750 MHz on this card. SLI overclocking is being done in one of our next tests and has been reserved for that content. . The GTX 970 and the 290X have been natural competitors with the GTX 970 holding its own against the aftermarket 290Xes, so a faster 390X should be a slightly slower competitor to the GTX 980 at around $450-499 . Thermals are measured using AIDA64. Our above chart includes the most up-to-date patch for benchmarking. The dual R9 390 setup experienced such frequent crashes in ACS that we could not operate the 1440p/ultra settings for longer than one minute in-game. Monitors supporting G-Sync and FreeSync are of particular importance for consideration when running SLI or CrossFire. Even though the GTX 970 beats the 980 in terms of value, the 980 still destroys previous generation cards. The effective memory clock speed is calculated from the size and data rate of the memory. At the lower two resolutions – 1080p and 1440p – the SLI GTX 970s marginally outperform the dual R9 390 configuration. It features 1664 SPUs along with 104 Texture Address Units and 64 Rasterization Operator Units. Parity of overclocks was checked using GPU-Z. More noticeable is the 0.1% low metric at 77.3FPS vs. 34.7FPS for the 2x R9 390s. PowerColor goes heavy on the metals for this card, and that's something that we'll look at more closely in the forthcoming, standalone review – sag is definitely a concern. Our thanks to supporting hardware vendors for supplying some of the test components. We moderate comments on a ~24~48 hour cycle. The number of GPUs supported when using a multi-GPU configuration. Following some astute reader suggestions, we've acquired a PowerColor Devil 13 dual-core R9 390 – two GPUs on one card – to test as a CrossFire stand-in against SLI GTX 970s. First world problems, Steve. ~170W is certainly a noticeable difference and … This seems most likely to be some sort of driver or game optimization issue – not particularly surprising, as ACS has experienced SLI / CF scalability issues several times in the past. Newer versions can support more bandwidth and deliver better performance. Even the 1% low and 0.1% low frametimes are respectable across the board here – respectable, but inconsequential for comparative purposes. jumping from a 16ms render to a 30ms or 40ms render time (or worse). 51.3FPS 0.1% low against an average throughput of 130FPS (1080p) will be detected as the occasional 'dip,' 'stutter,' or 'lag' (or other colloquialism) on rare occasion. At such framerates it becomes debatable how usable an extra 15 frames realistically is, but users seeking saturation of a 144Hz throughput potential would be advantaged by using the 2x R9 390s in this case. It is 8% percent faster that its predecessor the RX 480. This allows others to replicate our results by studying our bench courses. Why is AMD Radeon R9 390X better than Nvidia GeForce GTX 970? vs. MSI Radeon RX 480 Gaming 8GB. The 390x is an overclocked 290x with faster/more RAM. The width represents the horizontal dimension of the product. Parity is checked with GPU-Z. The 390X, for reference, now performs slightly better than the GTX 970 single card, whereas initial launch had the GTX 970 ahead of the R9 390X. The R9 390X is faster than the overclocked 290X or aftermarket 290Xes which trade blows with the factory overclocked GTX 970. NVidia's 361.43 drivers were used for testing the latest games. Adaptive synchronization technologies have helped to mitigate this phenomenon. Both cards share the same GPU but the R9 390 is factory overclocked. Small semiconductors provide better performance and reduced power consumption. It also is comprised of 1664 Stream Processors, 104 Texture Address Units, and 64 ROPs. At 4K, the R9 390 setup pulls ahead by 3.51% (58FPS vs. 56FPS AVG on the 970s). Overclocks were applied and tested for five minutes at a time and, if the test passed, would be incremented to the next step. Fallout 4 was unexpectedly brutal in this particular benchmark. Last modified on January 21, 2016 at 8:00 am, HW News - AMD CPU Surge in Steam Survey, SAM for Z490, Intel Rocket Lake, HW News - NZXT "Safety Issue," GPU Availability, AMD MI100 GPU , NVIDIA A100 80GB, HW News - NVIDIA Adds 'Smart Access Memory' Counter, Zen 3 Delid, Intel Add-in GPU, HW News - NVIDIA MSRP Allegedly Not Realistic, Ryzen 5000 Supply, PCIe 6.0 Spec. Unsurprisingly Nvidia are discontinuing the 780 Ti as it's now largely redundant. This is reflected abysmally in low frametimes for some tests, depending on whether or not the issue was reproduced during the test period. Another performance consideration for multi-GPU cards – in a similar vein to micro-stutter – 1% and 0.1% low frame performance can sometimes be worse than single-card setups. Allows you to connect to a display using DVI. Our test courses, in the event manual testing is executed, are also uploaded within that content. Newer versions of GDDR memory offer improvements such as higher transfer rates that give increased performance. We consider a smaller width better because it assures easy maneuverability. Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image. As with the previous test, 4K produces a slightly furthered lead for the AMD solution (8% – 61FPS vs. 56.3FPS AVG). Following some astute reader suggestions, we've acquired a, – two GPUs on one card – to test as a CrossFire stand-in against SLI. The GTX 970 having 169 better shader performance is not particularly notable, as altogether the R9 390X performs better when taking into account other relevant data. 1440p is, again, 1FPS different (1.13% delta). Moving to 1440p the R9 390 remains … AMD CrossFire setups, as of driver version 15.7 from July 2015, also fully support FreeSync. AMD Radeon R9 390X. It's almost always better to buy a newer, single card once that happens, as the spiked prices are hardly sane or good value. nVidia has clocked the core frequency at 1050 MHz. For a brand new system build, we'd generally advise in favor of a single-GPU for its versatility. OpenGL is used in games, with newer versions supporting better graphics. It was ugly. In these situations, disabling one of the two GPUs (but leaving the GPU physically installed) will reduce or eliminate micro-stutter, but then you're only getting half the investment outputting – certainly an unwanted situation. We shall overclock the 390X to compare it with the GTX 980, the R9 Fury X, the GTX 980 Ti, and even with the GALAX GTX 970 EXOC to determine the new card’s value. The power block is the most impressive – 32 pins of power (4x8-pin headers). NVidia SLI setups fully support G-Sync. This is another point that could potentially favor a single, higher-end GPU, but recent optimizations made to drivers and games may reduce the impact to manageable territory – we'll look at that below. Until a point at which scaling is properly supported on this configuration (Devil 13 with 2x R9 390s), it appears that Fallout 4 runs most efficiently on just about any other configuration. It made sense to just leave it as 'Gamers.'". There will be some delay after submitting a comment. ~170W is certainly a noticeable difference and will impact PSU selection. DirectX is used in games, with newer versions supporting better graphics. It's within 'unpleasant' territory when operating at full-tilt. Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. The Witcher 3 benefits SLI GTX 970s, producing a large 22.2% advantage at 1440p and 40% advantage at 4K resolution. Sniper Elite 4 Benchmark – R9 290X 2019 vs. RTX 2070, 2060, GTX 970, RX 590. The weight primarily comes from a rigid backplate for structural support, opposed by a thick alloy heatsink under the faceplate. This page is currently only available in English. Additionally the R9 390 sports a minimum of 8GB of VRAM versus 4GB on the R9 … SLI 970 noticeably better at 1080. We do not measure maximum or minimum FPS results as we consider these numbers to be pure outliers. We disable brand-supported technologies in games, like The Witcher 3's HairWorks and HBAO. A wider bus width means that it can carry more data per cycle. ... Thats what I get with an i5 3570K and an Asus Strix GTX 970 Yeah thats pure BS! Very bad value to buy multi-card for this game. The MSI Radeon R9 390X … GeForce GTX 970 vs Radeon R9 390X 8G. The latest AMD drivers (15.12) were used for testing. Some specific games are so heavily advantaged by multi-GPU – Black Ops III in particular, for both the 970s and CF 390s – that it'd be worth doing, but only if that game is going to be a primary source of entertainment or competition. We've done extensive testing with Black Ops III, including a graphics optimization guide for performance tuning. We technically have a line for the PCS Devil 13 above – but in reality, the card was more of a “DNF.” We were only able to get Assassin's Creed: Syndicate to survive for long enough to execute one test pass per game launch. We've already ruled that Just Cause 3 has poor multi-GPU scaling – twice, actually – but there's no harm in re-testing. Below we can see the performance of a yet unreleased GTX 96* class GPU, likely to be the GTX … 3DMark FireStrike Extreme (GFX test 2) is executed on loop for 25 minutes and logged. Very rarely – about once per four-minute test period – we observed a significant freeze in performance which endured for about 1-1.5 seconds. The 8% delta begins to enter a realm of possible detection by users, but isn't quite there yet. GPUs render alternating frames when using the AFR technique; more explicitly, GPU A will render all odd frames (1, 3, 5, 7) while GPU B renders all even frames (0, 2, 4, 6). Comparing performance between the 1070 and legendary GTX 970 shows that the newer 1070 wins by a whopping 50%. All rights reserved. Edit: Also, I'd like to add that the 390X seems like a good deal when compared to the GTX 980, but the 390/970 are just plain better price-performers than their bigger brothers anyhow. The performance gain – when there is one – does not seem to correlate with the 34.4% difference in power. To be fair, performance tuning on the 970s could produce a similar FPS – but for maxed settings, the 390s punch a bit higher. of a single GTX 980 Ti versus two GTX 970s in SLI. 64 points. The graphics card supports multi-display technology. At 1440p, the CrossFire R9 390s win-out over the SLI GTX 970s by a measurable 10.24% (154FPS vs. 139FPS). Before displaying results, remember that … Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. Comparing the GTX 970 and 780 Ti shows that the two cards offer comparable performance yet the new GTX 970 costs nearly half as much! GTA V had some anomalous issues with the CrossFire configuration during testing. We've already tested this 1140MHz vs. 1190MHz differential over here, if you're curious about what kind of delta that produces. AMD Radeon R9 390X vs Nvidia GeForce GTX 970, 2.51 TFLOPS higher floating-point performance, 1012MHz higher effective memory clock speed, XFX Radeon RX 580 GTS XXX Edition 1386MHz OC+, 8GB GDDR5, VR Ready, Dual BIOS, 3xDP HDMI DVI, AMD Graphics Card (RX-580P8DFD6), XFX Radeon RX 570 RS XXX Edition 1286MHz, 8gb GDDR5, DX12 VR Ready, Dual BIOS, 3xDP HDMI DVI, AMD Graphics Card (RX-570P8DFD6), XFX Radeon RX 580 GTS Black Edition 1425MHz OC+, 8GB GDDR5, VR Ready, Dual BIOS, 3xDP HDMI DVI, AMD Graphics Card (RX-580P8DBD6), AMD Radeon RX 480 8GB GDDR5 PCI Express 3.0 Gaming Graphics Card - OEM, Fit for XFX R9 390 8GB Graphics Cards AMD Radeon R9390 8GB Video Card GPU Board Desktop PC Computer Game Video Graphics Card, MSI Gaming Radeon RX 580 256-bit 4GB GDRR5 DirectX 12 VR Ready CFX Graphcis Card (RX 580 ARMOR 4G OC) (Renewed), Gigabyte Geforce GTX 1050 Ti 4GB GDDR5 128 Bit PCI-E Graphic Card (GV-N105TD5-4GD), Gigabyte GV-N1030OC-2GI Nvidia GeForce GT 1030 OC 2G Graphics Card, Asus GeForce GTX 1050 Ti 4GB Phoenix Fan Edition DVI-D HDMI DP 1.4 Gaming Graphics Card (PH-GTX1050TI-4G) Graphic Cards, GIGABYTE GeForce GTX 1660 Ti OC 6G 192-bit GDDR6 DisplayPort 1.4 HDMI 2.0B with Windforce 2X Cooling System Graphic Cards- Gv-N166TOC-6GD, Gigabyte Gv-N1660OC-6GD GeForce GTX 1660 OC 6G Graphics Card, 2X Windforce Fans, 6GB 192-Bit GDDR5, Video Card. Granted, that's the same as you'd find for most dual-card configurations, it just looks impressive on one card. Floating-point performance is a measurement of the raw processing power of the GPU. The SLI 970 configuration handily stomps the CF 390 FPS by 36.5%, which seems to be a result of non-existent CrossFire scaling in Fallout 4. The GTX 970s have superior 1% lows, but the gap between 65.3 and 72 1% low FPS is effectively imperceptible at the end of the day. This review of AMD's Radeon R9 390X benchmarks the MSI “Gaming” brand of the card, measuring FPS in the Witcher 3 & more, alongside power and thermal metrics. The bench uses the below components. Allows you to connect to a display using mini-DisplayPort. Also in that scenario, we'd always recommend buying that second card (if truly desired) before it exits production. When we compare the $429 MSI 390X Gaming 8G against the $479 GTX 980, it does OK at 3840×2160 but the gap widens further in favor of the GeForce below 4K resolutions. 980 Ti loses ground as resolution increases. PowerColor's Devil 13 video card is a three-slot, five-pound behemoth. Performance analysis is accompanied by power draw and thermal tests, though a proper, full review on the Devil 13 card will follow this content in short order. 54 ... Nvidia GeForce GTX 960. vs. Nvidia GeForce GTX 970. vs. AMD Radeon R9 390X. Abigail Torrez. 4K punishes the GTX 970s in the 0.1% low department, something we saw reflected across two re-tests (nine total test passes) for validation. The CF 390s exhibit significantly worse 0.1% and 1% low frametimes (more than 100% worse than the 970s), something we saw 'clinically' as framedrops while testing. According to benchmarks is somewhere between GTX 970or GTX 980. For today, the focus is on this head-to-head comparison. The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. At 1080p, the SLI 970s are advantaged by a noticeable 17.86% (122FPS vs. 102FPS AVG). Even as SLI scaling has improved, the delta against a single card is small enough that it'd be a waste to run two cards rather than a single, more powerful one. Copyright © 2020 GamersNexus, LLC. No, though 4K begins to enter this territory. Sniper Elite 4 will start us out. Our last head-to-head GPU comparison benchmarked the performance of a single GTX 980 Ti versus two GTX 970s in SLI. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. In comparison to the GTX 980 Ti / cut down GM200 the gap widens in favor of the R9 390X. Almost every time a card exits official production, prices spike on retailers and second-hand markets. Micro-stutter can be so extreme in some games and driver sets that SLI becomes undesirable, even if average FPS is improved over single-card configurations. Again, not hugely noticeable. CF scaling does not seem to work with the 2x390 Devil 13. A lower TDP typically means that it consumes less power. Disparity vanishes as resolution increases. At its stock speeds, the Devil 13 runs a core clock of 1100MHz and memory clock of 1350MHz. These measurements are outside of margin of error and were a combination of multiple test passes, validated as accurate. The PCS Dual R9 390 card puts the peak system load up to 582.73W, compared against the SLI GTX 970 power draw of 411.72W. Even factoring in overclocking, the R9 390 has just enough headroom to stay ahead of the overclocked GTX 970. There are two primary scenarios where SLI or CrossFire are used: A later upgrade when half the configuration is already owned and a day-one, brand new build. This stated, existing PC builds which already contain one of the two GPUs could benefit from an upgrade – and it'd be in the ~$300-$350 range (GTX 970 or R9 390), not in the $600+ range for a new build. It's a single-card solution branded as “dual-core,” pursuant to the existence of two R9 390 GPUs on the PCB. Average FPS, 1% low, and 0.1% low times are measured. As for frametimes, 0.1% metrics run poor on both the SLI and CrossFire configurations when compared against neighboring single-card alternatives. We'll also work toward answering the question of whether CrossFire and SLI are worth it in this particular scenario, as opposed to investing in a single, more expensive GPU. Comparing the GTX 980 and GTX 970 shows that the 970 only lags by around 17% in terms of performance but it's priced nearly 40% lower making the GTX 970 far better value for money card. This is similar to what we've seen on most of AMD's cards, which is generally an upward performance trend as resolution increases. PowerColor's Devil 13 is equipped with 16GB of GDDR5 memory, but that's not “stackable” memory for any of the games we tested; each GPU has access to its own 8GB GDDR5 pool, and they cannot share memory pools to exceed 8GB in DirectX 11. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing. Higher clock speeds can give increased performance in games and other apps. The benchmark specifically uses MSI R9 390X Gaming 8G and MSI GTX 970 Gaming 4G cards vs. 2x GTX 970s, 1x GTX 970, and 1x R9 390X for baseline comparisons. This chart and data will be discussed more heavily in our future review of the card, since thermals are more heavily impacted by coolers and AIB partners in multi-GPU situations. Game settings were manually controlled for the DUT. While the Radeon RX 580 has a similar performance to the GTX 1060. Thanks to the overclock out of the box, the card matches GTX 980 performance at 1440p and beyond. 1080p fronts a ~1FPS difference, or 0.87% delta. 1440p saw a 6.1% AVG FPS delta that favored the 970s, but severely low 0.1% output (8FPS) on the 2x 390s prohibited smooth play. The number of textured pixels that can be rendered to the screen every second. We have reached-out to appropriate parties and are researching this issue. The Devil 13 uses a three-fan array for cooling, each using a five-fin scoop design. Instead, we take an average of the lowest 1% of results (1% low) to show real-world, noticeable dips; we then take an average of the lowest 0.1% of results for severe spikes.
