The NVIDIA GeForce GTX 1080 Ti Founder's Edition Review: Bigger Pascal for Better Performance
by Ryan Smith on March 9, 2017 9:00 AM ESTCompute
Shifting gears, let’s take a look at compute performance on GTX 1080 Ti.
Starting us off for our look at compute is LuxMark3.1, the latest version of the official benchmark of LuxRender. LuxRender’s GPU-accelerated rendering mode is an OpenCL based ray tracer that forms a part of the larger LuxRender suite. Ray tracing has become a stronghold for GPUs in recent years as ray tracing maps well to GPU pipelines, allowing artists to render scenes much more quickly than with CPUs alone.
The OpenCL situation for NVIDIA right now is a bit weird. The company is in the middle of rolling out OpenCL 2.0 support to their video cards – something that I had actually given up hope on until it happened – and as a result their OpenCL drivers are in a state of flux as company continues to refine their updated driver. The end result is that OpenCL performance has dipped a bit compared to where the GTX 1080 launched at back in May, with said card dropping from 4138 points to 3648 points. Not that the GTX 1080 Ti is too fazed, mind you – it’s still king of the hill by a good degree – but the point is that once NVIDIA gets their drivers sorted out, there’s every reason to believe that NVIDIA can improve their OpenCL performance.
For our second set of compute benchmarks we have CompuBench 1.5, the successor to CLBenchmark. CompuBench offers a wide array of different practical compute workloads, and we’ve decided to focus on face detection, optical flow modeling, and particle simulations.
Like LuxMark, CompuBench shows some minor performance regressions on the GTX 1080 as compared to the card’s launch. None the less, this doesn’t do anything to impede the GTX 1080 Ti’s status as the fastest of the GeForce cards. It dominates every sub-benchmark, including Optical Flow, where the original GTX 1080 was unable to pull away from AMD’s last-generation Radeon R9 Fury X.

I've given Ryan a LOT of heat for the last years complete lack of or very late reviews.But I'm also one to give credit where credit is due.
Amazing review Ryan, this rabbit you pulled you should be really proud of and the fact that you didn't hurt yourself on some motherboard or screwdriver and got it done on launch is really remarkable. Quite surprising as I'd thought Anandtech would start to do less PC hardware reviews and focus more on mobile.
Really amazing work and finally back to the highest of standard, quality and timely reviews that Anand was known for. This great work is what I think he saw in you, and I hope you can keep it up and keep AT at this level as "the bench" which all other reviews are measured!
Thank you!

Cool review! Thanks for the lauch day.I think everyone knew exactly how this was going to perform, as it was pretty much a TItan, less 1 GB of GDDR5X (although a bit faster due to newer bins) and 88 rather than 96 ROPs. Otherwise largely identical.
Let's hope AMD has a good response in Vega.

The timeliness of this review has been great, but I was wondering about reviews for any of the Polaris family, especially the 480 and 460. I know there was a preview on the 480, but are there any plans to do a full review on any of the parts?Meteor2 - Friday, March 10, 2017 - link
The 'preview' of the RX 480 wasn't really any less detailed than this review, it's just missing compute and synthetic benchmarks. Plenty of detail on the background to the card and the architecture.ElBerryKM13 - Thursday, March 9, 2017 - link
Cmon anandtech? no Pascal Titan X benchmarks to see how it compares to this 1080ti? are you serious?Ryan Smith - Thursday, March 9, 2017 - link

Whoah, what a monster card!HomeworldFound - Thursday, March 9, 2017 - link
It would've been nice to test more modern games than that, at least introduce Resident Evil 7 etc. Of course a new high end card is going to play old games better....Holliday75 - Thursday, March 9, 2017 - link
And a newer card will play newer games better as well.Ryan Smith - Thursday, March 9, 2017 - link
We'll be refreshing the benchmark suite for Vega, that way we go into a new architecture with equally new games.
