Both Vulkan games, Doom and The New Colossus, show poor minimums on the Titan V. There are plenty of games where performance is substantially better, but then there are some clear problems in a few cases. While average framerates are higher, minimum fps ends up being a bit of a wash, but that doesn't tell the full story. Titan V takes diminishing returns to a new level, with 13 percent better 4K performance on average, and a best-case result of 27 percent better performance in a couple of games, but this time with a price premium of 325 percent.Īs I mentioned earlier, there are also a few stumbles in our gaming tests, particularly in terms of minimum fps. The Titan Xp was already highly questionable, delivering a few percent better performance than a GTX 1080 Ti with about a 70 percent price premium. Not practical for gaming on the other hand… Yeah. The Titan V is the fastest gaming graphics card around, beating the GTX 1080 Ti by an average of 13 percent at 4K. This isn't a value proposition at all, but it does give us a tantalizing taste of what we might see in a future GeForce branded card. And at only a bit more than four times the cost. The Tensor cores are also rather specialized, and while it's possible to use them for certain gaming calculations, don't count on that happening-Tensor code will need to be specifically written for the processors.īut we're here for the games, right? If you've got three grand burning a hole in your wallet and you simply must have the fastest single GPU gaming solution, Titan V is generally the winner, easily surpassing the GTX 1080 Ti in most games. The use of the Tensor cores or CUDA cores in each SM is exclusive, however, so if you want access to the 110 TFLOPS of FP16 performance from the Tensor cores, that's not in addition to the CUDA performance. The GPU can also run FP32 CUDA calculations at up to 14.9 TFLOPS, or FP64 at half that level, 7.45 TFLOPS.

This results in some interesting options, including double-speed FP16 CUDA calculations. Note that unlike previous GeForce and Titan cards, the Titan V is using the full capabilities of the Volta GV100 architecture.

If you run apples-to-apples tests without the Tensor cores, the Titan V still does 308 images/s-so 28 percent faster than the Titan Xp, which is close to the theoretical difference in TFLOPS. Nvidia gives sample performance of up to 609 images per second for Resnet-50 training using the Tensor cores, compared to 240 images/s with a Titan Xp (which obviously lacks the Tensor cores), making the Titan V 154 percent faster. Seeing this much computational power packed into a single GPU is insane. The card is rated to do up to 110 TFLOPS (that's trillions of floating-point operations per second), which used to be the realm of the fastest supercomputers. It's really fast at certain computations, specifically FP16 operations using the Tensor cores. Let me also get this one out of the way, since it's ostensibly why Nvidia released the Titan V.

Volta is a brand-new architecture that's quite different from Pascal and Maxwell, with 64 CUDA cores per SM (instead of the usual 128), HBM2 memory, and other changes that Nvidia hasn't fully disclosed at this time. There are a few stumbles here and there, likely thanks to the early nature of the drivers, but overall Volta shows a lot of potential. I ran 22 gaming benchmarks on the Tiki, at my usual 1080p, 1440p, and 4K ultra settings. Nvidia says the Titan V isn't for gaming, but that didn't stop me.
