This GP100 is a real beast. For those who are concerns about FP16/32/64 mix can have a look at https://devblogs.nvidia.com/parallel...inside-pascal/ where clearly the GP100 is a real good beast at 16, 32 as well as 64 FP compute. And all of this fits in the 300W range which is really nice.

Maybe somebody should read the announcment correctly, possible OEM cards like a successor to current GTX 980 Ti will not be available this year. They might sell a Titan upgrade at premium price later this year, depending on the yield i would guess. Tesla is extremely expensive. So you can soon expect some GDDR5X cards with Pascal chips for average gamers.Last edited by Kano; 06 April 2016, 06:56 AM.

If GP102 or GP104 only have GDDR5(X) and not HBM, that would be really lame.Last edited by juno; 06 April 2016, 07:03 AM.

Mass production is an elastic term, do you expect good yields in the beginning? Usually it will get cheaper over time. AMD used 4 GB HBM and from benchmarks it was less impressive than from the specs. GDDR5X supports the double data rate over GDDR5, so memory speed should not be so problematic and should be at least 25 % faster than the HBM from the Fury X.

Of course, I don't know how Samsung's HBM yields are. The low clocked DRAM itself should be easy to do. Samsung also has some years of experience with TSVs. There are still some things that could go wrong, obviously.
Fiji's problem was the limited capacity of HBM at this time, not the technology itself. And it is not drowning in insufficient memory bandwidth, so what should have benchmarks been showing in your opinion? I also see Fiji as some sort of a test drive vehicle for HBM and 2.5D stacking. Of course it has drawbacks due to the old 28 nm process.
I also don't get what you are trying to say about memory bandwidth. GP100 seems to utilise 1.4 Gbps (720 GiB/s), Fiji had 1.0 Gbps (512 GiB/s), both at 4096 bits wide interfaces. GDDR5X will provide 10 Gbps from the start, using a sane 256 bit interface, resulting in 320 GiB/s.

Edit: Also, I'm thoroughly disappointed in the announcement, as I was expecting something consumer oriented to be announced as well. As it is now, we still know nothing about Pascal, besides some SM and FPxx units count.Last edited by bug77; 06 April 2016, 09:58 AM.

It appears that GP102 will be the top GPU for GeForce products this year, which might be similar to GP100 with some of FP64 and the NVLink support stripped out. Hopefully they will add more CUDA cores to push the FP32 performance.
