So I'm not sure why you're saying Nvidia locked it, Maxwell was never designed with it.Welcome to /r/NVIDIA. There isn't even a Quadro Maxwell product that had Kepler FP64 performance.

The Titan Black had full FP64, it was cut in the Maxwell variant because Maxwell lacked FP64 hardware across the entire GPU lineup. If I was a compute/neural networking person though? This is a steal at $1200.įirst of all Titan X-Maxwell was an extremely popular card in the HPC market for neural networks. The price increase isn't worth the performance over the 1080. With the FP16x2 cores it's over 2.1x the speed of the Titan X (Maxwell) for Neural Networks in single precision.Īs a gamer, I wouldn't buy this. So even if FP64 is locked, this card is still extremely good for HPC market. GP104/106 do not have these cores, they have cores that are more similar to Maxwell. Which means the FP16 performance is double whatever FP32 is. Regardless, part of Pascal's design improvements on GP100 is that each FP32 core has support for two full FP16 operations per cycle. Second, there is no confirmation whether FP64 is locked on this Titan, at least I can't find any. So I'm not sure why you're saying Nvidia locked it, Maxwell was never designed with it. You're probably talking about FP64, which was cut in the Titan X (Maxwell).Ĭlick to expand.First of all Titan X-Maxwell was an extremely popular card in the HPC market for neural networks. The FP16/Int8 support and 12GB of ram makes it huge for compute. Nvidia wouldn't put 16GB of HBM2 here, it would up the cost dramatically and just cut into their P100 sales. There is no way they are going to sell the bigger chip as the cheaper variant. It's cut down the first place because it's so expensive to make and they are trying to recover as many dies as possible. Same thing will probably happen here when it refreshes.ģ840 and I doubt it. One of the things Nvidia did with Maxwell was removed the FP64 hardware so they could shove a bunch more cores into it. Not to mention that the P100 has a split SM and double register/cache. There are 32 FP64 cores per SM and 60 SM's (in GP100) so 1600 FP64 cores that could technically be FP32 cores. They don't advertise the FP64 so it's possible that they limited performance there intentionally, but because it's the same core count and because it features INT8 (which GP104 cores don't support), I think it's safe to assume that the FP64 hardware is there, taking up die space. This card has the same core count as the P100.
