Not directly translatable to gaming performance unfortunately no.
But it shows that Nvidia is going back to fully unlocked GPGPU chips with the big boys.

Double precision with Maxwell was just horrible.

Thank god for the DP performance. It's so good for someone who games and does computational work.

The double-precision FLOPS number is literally meaningless for gaming.

Single-precision FLOPS are meaningful for gaming only if you're comparing two chips of the same microarchitecture with the same shader design and similar proportions of resources to keep the shaders fed equally.

FLOPS are tricky since they're directly affected by clock speed and Nvidia have different base, boost, and actual clock speeds with their chips. But for the Titan X, they cite 7 TFLOPS:

11024153_1578978145678598_1028826680_n.jpg


Assuming Pascal and Maxwell are very similar microarchitectures, that would put GP100/big Pascal's shader/gaming performance at ~71.4% more than GM200/big Maxwell, but that can differ depending on how well Pascal overclocks versus Maxwell and whether Nvidia were consistent in how they calculated FLOPS.

Should help sell a crapload of Titan cards thats for sure

Not sure why they look at HMC though...

So around 75% improvement from Maxwell, assuming apples to apples (shaders, rops, and whatever else scaling similarly in count) in gaming, and 400% in computational power.

Actually sounds a bit more impressive than I was expecting to be honest.

Not sure I like the added DP on the Titan for purely selfish reasons of now having to compete with the enterprise and small businesses wanting to buy them up for the DP performance.

More like 100% once they gimp Maxwell.

We may not see the same numbers with the GeForce card though. I'm sure there is a way for them to cutback the DP performance for the GeForce version.

Pretty impressive for sure. I'd imagine if they're starting to talk this big of a leap in performance a pretty scaled down chip. Mini Pascal for the 1080 and 1070... Sub 175w...?

Tbh 75% is still a letdown, unless Pascal really is just Maxwell on 20nm 16nm FF+ with minimal architectural changes.

I was expecting 100% improvement minimum to be quite frank.
