Compute Performance: Geekbench 4

In the most recent version of its cross-platform Geekbench benchmark suite, Primate Labs added CUDA and OpenCL GPU benchmarks. This isn’t normally a test we turn to for GPUs, but for the Titan V launch it offers us another perspective on performance.

Compute: Geekbench 4 - GPU Compute - Total Score

The results here are interesting. We’re not the only site to run Geekbench 4, and I’ve seen other sites with much different scores. But as we haven’t used this benchmark in great depth before, I’m hesitant to read too much into it. What it does show us, at any rate, is that the Titan V is well ahead of the Titan Xp here,  more than doubling the latter’s score.

Looking at the subscores, the Titan V handily outperforms the Titan Xp on all of the subtests. However it’s one test in particular that stands out here, and is likely responsible for the huge jump in the overall score, and that’s the Gaussian Blur, where the Titan V is 9x (!) faster than the Titan Xp. I am honestly not convinced that this isn’t a driver or benchmark bug of some sort, but it may very well be that Primate Labs has hit on a specific workload or scenario that sees some rather extreme benefits from the Volta architecture.

Folding @ Home

Up next we have the official Folding @ Home benchmark. Folding @ Home is the popular Stanford-backed research and distributed computing initiative that has work distributed to millions of volunteer computers over the internet, each of which is responsible for a tiny slice of a protein folding simulation. FAHBench can test both single precision and double precision floating point performance, giving us a good opportunity to let Titan V flex its FP64 muscles.

Compute: Folding @ Home, Double and Single Precision

A CUDA-backed benchmark, this is the first sign that Titan V’s performance lead over the Titan Xp won’t be consistent. And more specifically that existing software and possibly even NVIDIA’s drivers aren’t well-tuned to take advantage of the Volta architecture just yet.

In this case the Titan V actually loses to the Titan Xp ever so slightly. The scores are close enough that this is within the usual 3% margin of error, which is to say that it’s a wash overall. But it goes to show that Titan V isn’t going to be an immediate win everywhere for existing software.


Our final set of compute benchmarks is another member of our standard compute benchmark suite: CompuBench 2.0, the latest iteration of Kishonti's GPU compute benchmark suite. CompuBench offers a wide array of different practical compute workloads, and we’ve decided to focus on level set segmentation, optical flow modeling, and N-Body physics simulations.

Compute: CompuBench 2.0 - Level Set Segmentation 256

Compute: CompuBench 2.0 - N-Body Simulation 1024K

Compute: CompuBench 2.0 - Optical Flow

It’s interesting how the results here are all over the place. The Titan V shows a massive performance improvement in both N-Body simulations and Optical Flow, once again leading to the Titan V punching well above its weight. But then the Level Set Segmentation benchmark is practically tied with the Titan Xp. Suffice it to say that this puts the Titan V in a great light, and conversely makes one wonder how the Titan Xp was (apparently) so inefficient. The flip side is that it’s going to be a while until we fully understand why certain workloads seem to benefit more from Volta than other workloads.

    Bah but this is last week's Titan, aren't they launching a new one this week?
  • WorldWithoutMadness - Thursday, December 21, 2017 - link

    Titan A, next week Titan G, next 2 weeks Titan I, next month Titan N, and lastly Titan AS

    Don't forget the dual Volta Titan ZZ
  • mode_13h - Wednesday, December 27, 2017 - link case anyone wondered why they never released Pascal as Titan P. I guess Nvidia knows their market too well for that.
  • mode_13h - Wednesday, December 27, 2017 - link

    Well, they'll presumably release the GV102 in some more affordable flavor of Titan. Titan V0?

    And maybe they'll eventually release a GV100 in a PCIe card with all four HBM2 stacks... although that'll probably receive Quadro branding & price point, like the Quadro GP100.
  • mode_13h - Tuesday, January 30, 2018 - link

    So, after Titan Xp and Titan V(ista), next should be Titan 7. That's a definite buy, but I'd skip Titan 8. Maybe go for Titan 8.1, or just hold out for Titan 10.

    OK, while I agree that nobody should buy a Titan V for gaming you say: "Already after Battlefield 1 (DX11) and Ashes (DX12), we can see that Titan V is not a monster gaming card, though it still is faster than Titan Xp. "

    Uh... yeah that's wrong. Anything that's faster than a Titan XP *is* a monster gaming card by definition. It's just not a very good purchase for $3000 since it's not really targeted towards gaming.
  • nathanddrews - Wednesday, December 20, 2017 - link

    I agree with this. Cost aside - it's the best gaming card on the market. Unless NVIDIA launches the 1180/2080/whatever80 soon, this card will be in Terry Crews' Old Spice rig by the end of the month.

    "Uh... yeah that's wrong. Anything that's faster than a Titan XP *is* a monster gaming card by definition."

    The big issue right now is that it's not consistently faster, especially at the 99th percentile Or for that matter, not as bug-free as it needs to be.

    I'm going to be surprised if it doesn't get better with later drivers. But for the moment, even if you throw out the price, it's kind of janky in games.
