A user named "Vega" who owns a TitanXp has obtained a TitanV and did some benchmarks:

That's really nuts. And bodes well for gaming volta. Or ampere, or whatever is next gaming generation.In every case, this card uses less power than the 1080ti while being 50% faster.
While finally starting to ship EPYC in reasonable quantities and preparing Zen refresh?AMD is probably quaking in their boots seeing this...

I guess the same applies to Vega?I would venture a guess that a lot of the power consumption reduction is due to HMB2 which is not going to be the case for consumer products.
But the upper Nvidia consumer cards would probably be using GDDR6 going forward, which has advantages over GDDR5/X.I would venture a guess that a lot of the power consumption reduction is due to HMB2 which is not going to be the case for consumer products.
Some notes:
[*]This implementation has 25% of the memory and ROPs disabled, giving us 12GB of HBM2, a 3072-bit bus, and 96 ROPs.
[*]Clock speeds in our testing look to be much higher than the base AND boost ratings.
[*]So far, even though the price takes this out of the gaming segment completely, we are impressed with some of the gaming results we have found.
[*]The cooler might LOOK the same, but it definitely is heavier than the cooler and build for the Titan Xp.
Well it is not really an efficient dedicated FP32 GPU die but a huge mixed-precision die, and like I mentioned pretty obvious would hit a thermal and power wall when compared to a Titan Xp.So the earlier reports of boosting to 2Ghz were wrong, the card gains nicely in some games in GN's review with more power. nvidia have similar problem as AMD now where the chips aren't scaled?
Waiting for duderandom84 to get one for a clock for clock comparison.
It can be easily overclocked to 1.9GHz though. That's pretty solid given the massive size of to the chip.So the earlier reports of boosting to 2Ghz were wrong
Vega scaling problems are universal, TitanV have spotty scaling in some cases at best. It usually scales pretty close to its advantages in FP32, despite being hampered by reduced clocks and less ROPs. A lighter version of Volta with higher clocks and more ROPs (sacrificing FP64 and Tensor) can easily take care of the problem. Volta at 1.8GHz gains significant chunk of performance. Also Frame pacing issues suggest a not fully optimized driver as of yet.nvidia have similar problem as AMD now where the chips aren't scaled?
Though they completely destroyed their gaming benchmarks by using a gen 3 Core i7, thus having their entire high end GPU stack massively CPU limited! Even their 1080Ti is barely 10% faster than their regular 1080!German site hardwareluxx.de got themselves a Titan V and ran Luxmark 3 as well as GPU pi:
