The 2018 GPU Benchmark Suite & the Test
Another year marks another update to our GPU benchmark suite. This time, however, is more in line with a maintenance update than it is a complete overhaul. Although we've done some extended compute and deep learning benchmarking in the past year, and even some HDR gaming impressions, our compute and synthetic lineup remains largely the same. But before getting into the details, let's start with the bulk of benchmarking, and the biggest reason for these cards anyhow: games.
Joining the 2018 game list is Far Cry 5, Wolfenstein II, Final Fantasy XV and Middle-earth: Shadow of War. We are also bringing in F1 2018 and Total War: Warhammer II. Returning from last year is Battlefield 1, Ashes of the Singularity: Escalation, and Grand Theft Auto V. All-in-all, these games span multiple genres, differing graphics workloads, and contemporary APIs, with a nod towards modern and relatively intensive games.
| AnandTech GPU Bench 2018 Game List | ||||
| Game | Genre | Release Date | API(s) | |
| Battlefield 1 | FPS | Oct. 2016 | DX11 (DX12) |
|
| Far Cry 5 | FPS | Mar. 2018 | DX11 | |
| Ashes of the Singularity: Escalation | RTS | Mar. 2016 | DX12 (DX11, Vulkan) |
|
| Wolfenstein II: The New Colossus | FPS | Oct. 2017 | Vulkan | |
| Final Fantasy XV: Windows Edition | JRPG | Mar. 2018 | DX11 | |
| Grand Theft Auto V | Action/Open world | Apr. 2015 | DX11 | |
| Middle-earth: Shadow of War | Action/RPG | Sep. 2017 | DX11 | |
| F1 2018 | Racing | Aug. 2018 | DX11 | |
| Total War: Warhammer II | RTS | Sep. 2017 | DX11 (DX12) |
|
That said, Ashes as a DX12 trailblazer may not be as hot and fresh as it once was, especially considering that the pace of DX12 and Vulkan adoption in new games has waned. The circumstances are worth an investigation on their own, but the learning curve required in modern low-level API and the subsequent return may not be convincing right now. As a more general remark, most developers and publishers tend not to advertise or document DX12 support as much as they used to, nor is it clearly labelled in game specifications as many times DX11 is the unmentioned default.
Particularly for NVIDIA and GeForce RTX, pushing DXR and raytracing means pushing DX12, of which DXR is a component. The API has a backstop in the form of Xbox consoles and Windows 10, and if multi-GPU is to make a comeback, whether that's via compatible workloads (VR), flexible usage (ray tracing workload topologies), or just the plain old inevitability of Moore's Law. So this is less likely to be the slow end of DX12.
In terms of data collection, measurements were gathered either using built-in benchmark tools or with AMD's open-source Open Capture and Analytics Tool (OCAT), which is itself powered by Intel's PresentMon. 99th percentiles were obtained or calculated in a similar fashion, as OCAT natively obtains 99th percentiles. In general, we prefer 99th percentiles over minimums, as they more accurately represent the gaming experience and filter out any artificial outliers.
We've also swapped out Blenchmark, which seems to have been abandoned in terms of updates, in favor of a BMW render from the Blender Institute Cycles Benchmark, and a more recent one from a Cycles benchmark developer on Blenderartists.org. There were concerns with Blenchmark's small tile size, which is not very applicable to GPUs, and in terms of usability we also ran into some GPU detection errors which were linked to inaccurate Blenchmark Python code.
Otherwise, we are also keeping an eye on a few trends and upcoming developments:
- MLPerf machine learning benchmark suite
- Blender Benchmark
- Futuremark's 3DMark DirectX Raytracing benchmark
- DXR and Vulkan raytracing extension support in games
Another point is that we do not have a permanent HDR monitor for our testbed, which would be necessary to incorporate HDR game testing in the near future; 5 games in our list actually support HDR. And as we look at technologies that enhance or alter image quality (e.g. HDR, Turing's DLSS), we will want to find a better way of comparing differences. This is particularly tricky with HDR as screenshots are inapplicable and even taking accurate photographs will most likely be viewed on an SDR screen. With DLSS, there is a built-in reference quality based on 64x supersampling, which in deep learning terms is the 'ground truth'; an intuitive solution would be to use a neural network based method of analyzing quality differences, but that is likely beyond our scope.
The following tech demos and test applications were provided via NVIDIA:
- Star Wars 'Reflections' Demo (includes real time ray tracing and DLSS support)
- Final Fantasy XV Official Benchmark (includes DLSS support)
- Asteroids Demo (features mesh shading and variable LOD)
- Epic Infiltrator Demo (features DLSS)
The Testbed
Because NVIDIA is not productizing any other reference-quality GeForce RTX 2080 Ti and 2080 card besides the Founders Editions, which are non-reference by specifications, we've gone ahead and emulated the true reference specifications with a 90MHz downclock and lowering the TDP by roughly 10W. This is to keep comparisons standardized and apples-to-apples, as we always look at reference-to-reference results.
In a classic case of Murphy's Law, our usual PSU started malfunctioning around the time of the review, but given the time constraints we couldn't do a 1:1 replacement in time. As it is a digital PSU, we were beginning to use it for PCIe power readings to augment system measurements, but for now we will have to stick power draw at the wall. For the time being, we've swapped it out with another high-quality and high-wattage PSU.

It also glosses over the huge pricing differences and the fact that most gamers buy AIB models, not reference cards.noone2 - Thursday, September 20, 2018 - link
Not sure why people are so negative about these and the prices. Sell your old card and amortize the cost over how long you'll keep the new one. So maybe $400/year (less if you keep it longer).If you're a serious gamer, are you really not willing to spend a few hundred dollars per year on your hardware? I mean, the performance is there and it's somewhat future proofed (assuming things take off for RT and DLSS.)
A bowling league (they still have those?) probably costs more per year than this card. If you only play Minecraft I guess you don't need it, but if you want the highest setting in the newest games and potentially the new technology, then I think it's worth it.

Performance is not there. Around 20% actual performance boost is not very convincing especially due much higher price. How can you be positive about it?Future tech promise doesn't add that much and it is not clear if game developers will bother.
When one spend $1000 of GPU it has to deliver perfect 4k all maxed gaming and NV charges ever more. This is a joke, NV is just testing how much they can squeeze of us until we simply don't buy.

The article clearly says that the Ti is 32% better on average.The idea about future tech is you either do it and early adopters pay for it in hopes it catches on, or you never do it and nothing ever improves. Game developers don't really create technology and then ask hardware producers to support it/figure out how to do it. Dice didn't knock on Nvidia's door and pay them to figure out how to do ray tracing in real time.
My point remains though: If this is a favorite hobby/pass-time, then it's a modest price to pay for what will be hundreds of hours of entertainment and the potential that ray tracing and DLSS and whatever else catches on and you get to experience it sooner rather than later. You're saying this card is too expensive, yet I can find console players who think a $600 video game is too expensive too. Different strokes for different folks. $1100 is not terrible value. You talking hundreds of dollars here, not 10s of thousands of dollars. It's drop in the bucket in the scope of life.

So Just Buy It then? Do you work for toms? :DTheJian - Thursday, September 20, 2018 - link
"Ultimately, gamers can't be blamed for wanting to game with their cards, and on that level they will have to think long and hard about paying extra to buy graphics hardware that is priced extra with features that aren't yet applicable to real-world gaming, and yet only provides performance comparable to previous generation video cards."So, I guess I can't read charts, because I thought they said 2080ti was massively faster than anything before it. We also KNOW devs will take 40-100% perf improvements seriously (already said such, and NV has 25 games being worked on now coming soon with support for their tech) and will support NV's new tech since they sell massively more cards than AMD.
Even the 2080 vs. 1080 is a great story at 4k as the cards part by quite a margin in most stuff.
IE, battlefield 1, 4k test 2080fe scores 78.9 vs. 56.4 for 1080fe. That's a pretty big win to scoff at calling it comparable is misleading at best correct? Far Cry 5 same story, 57 2080fe, vs. 42 for 1080fe. Again, pretty massive gain for $100. Ashes, 74 to 61fps (2080fe vs. 1080fe). Wolf2 100fps for 2080fe, vs. 60 for 1080fe...LOL. Well, 40% is, uh, "comparable perf"...ROFL. OK, I could go on but whatever dude. Would I buy one if I had a 1080ti, probably not unless I had cash to burn, but for many that usually do buy these things, they just laughed at $100 premiums...ROFL.
Never mind what these cards are doing to the AMD lineup. No reason to lower cards, I'd plop them on top of the old ones too, since they are the only competition. When you're competing with yourself you just do HEDT like stuff, rather than shoving down the old lines. Stack on top for more margin and profits!
$100 for future tech and a modest victory in everything or quite a bit more in some things, seems like a good deal to me for a chip we know is expensive to make (even the small one is Titan size).
Oh, I don't count that fold@home crap, synthetic junk as actual benchmarks because you gain nothing from doing it but a high electric bill (and a hot room). If you can't make money from it, or play it for fun (game), it isn't worth benchmarking something that means nothing. How fast can you spit in the wind 100 times. Umm, who cares. Right. Same story with synthetics.

It's future tech that cannot deliver *now*, so what's the point? The performance just isn't there, and it's a pretty poor implementation of what they're boasting about anyway (I thought the demos looked generally awful, though visual realism is less something I care about now anyway, games need to better in other ways). Fact is, the 2080 is quite a bit more expensive than a new 1080 Ti for a card with less RAM and no guarantee these supposed fancy features are going to go anywhere anyway. The 2080 Ti is even worse; it has the speed in some cases, but the price completely spoils the picture, where I am the 2080 Ti is twice the cost of a 1080 Ti, with no VRAM increase either.NVIDIA spent the last 5 years pushing gamers into high frequency displays, 4K and VR. Now they're trying to do a total about face. It won't work.

Thanks for rushing the review out. BTW, the auto-play video on every AT page has got to stop. You are turning into Tom's Hardware.milkod2001 - Friday, September 21, 2018 - link
They are both owned by Purch. Marketing company responsible for those annoying auto play videos and the lowest crap possible From the web section. They go with motto: Ad clicks over anything. Don't think it will change anytime soon. Anand sold his soul twice to Apple and also his web to Purch.mapesdhs - Thursday, September 27, 2018 - link
