Looks like nay sayers were wrong about the new Titan having HBM2.
You think P204 will be on GDDR? They'll split their lines like that? How is that "known"?
No they didn't. The 390 series was all rebrands, only the furys were new.
It's gotta be far off, he didn't even have a board or GPU to show. Very telling.If they were releasing consumer Pascal cards "soon" then why didn't they mention it?
Why no working silicon if it's so soon?
Tahiti...?Tahiti was half of a Fury. SAME ARCHITECTURE, DIFFERENT MEMORY CONTROLLERS.
Tahiti = GDDR5.
Fury = HBM1

Although I cut off the stream right after he showed their new super computer.
Tahiti...?
Tonga is a better example. Fury X is literally two 380X's duct taped together.
You're right, I forgot fury was still GCN 1.2.
Back to topic, P104s-- if they were coming, wouldn't they make the keynote?
There is no need to mention it yet, why? That isn't the point of this conference, its not about gaming its all about HPC and Compute. If they already have p100's in mass production, you don't think p104's are going to be harder to produce? If they are releasing software that is specific for Pascal in June, don't people need those cards to use that software?
If they are in mass production then surely he could have gotten his hands on one, right?
It's fluff. The GP100 is so impressive because it doesn't exist. This is a pre-emptive strike to steal AMD's thunder.

Yep, we have no clue how long.
Should be a solid window of opportunity for AMD.
This gpu has 10.75tflops of fp32 throughout, ~21 tflops fp16.They're saying a ~6x speedup in deep learning performance in a cluster (fp16) versus the older cards (I scaled the Pascal cluster down to 4 to be comparable).
There's only a 75% increase in compute performance over Titan X.
So this must be due to the new NVLINK interconnect plus the much faster memory bus? Guess Maxwell compute was truly bandwidth-limited...but we knew that already

Unless they release a totally modified Gp100 with reduced fp 64 cores and more fp32 I think I'm sticking to my 8.5tflop monster
Yet to see if fp16 capabilities will appear in consumer line, if so I'll be more than happy to buy gp104
Also seems like they chose to produce a lower density chip, they can fit ~20B transistors on 600mm easily
I think the big increase in fp32 comes from clock, gm200 throughput was based on base clocks not boost. At 1500mhz a 980ti does 8.5T
Having said that if thus overclocks anything like maxwell it will be truly monstrousOh damn you're right, I FORGOT!
I thought Maxwell already had double-speed FP16, but I was thinking of the Tegra X1 announcement months ago.
This means half of that 6x performance improvement can be attributed to the double fp16 throughput. So It's a lot more reasonable to place the 6x speedup on 3x higher fp16 compute plus the extra bandwidth
I guess I shouldn't try to think and post when I'm following something like this.
Well this is a half node, so I don't think it was as hard of a transition as one would expect.
Yeah if they can get a 50% increase from overclocking, like what Maxwell 2 gets that would be crazy.
Well the masks and metal layer are similar to 20nm.
HBM memory controller is part of the die space, but it is much smaller that traditional GDDR, which HBM is around 30% smaller.
yes I expect a hard limit as well, with power concerns with OC'ing, Fin Fet's transistor tolerances to frequency increase tend to scale up fast once out of its ideal ranges.
Boo! No consumer card timeline.

Paper launch? To head off Intel? Nvidia maybe on the verge of loosing the HPC market or start the downward spiral. Not sure if AMD is seriously targeting this market yet.
If Nvidia has P100 working then P104 should not be far behind and this event does not look appropriate to discuss gaming cards that cost pennies compared to these bad boys.
