Nvidia experimenting with HBM?

Hey there!

I've found this Nvidia presentation about HBM, if you take a look at page 3 there's a

Fury X

look-alike made by Nvidia.

Have you seen this before elsewhere, any details on it?

Cheers!

Both companies have been experimenting with 3d memory for years now.

,Isn't it known that pascal will have HBM ?

AMD doesn't have copyright over it ( that I know of )

 

Pascal gpu's will hopefully blow our socks off :D

Recommend what is best, not what you preffer.

"Like" comments to show your support of them or the idea they express.

Well Pascal will come with HBM2. 

And they have planned on using HMC first for Volta, which is really close to HBM anyway (in concept)

I think its 100% certain Nvidia is playing with HBM.

 

The question really is when they'll release it.

Pascal in 3 quarters ;) that is also 100% sure

Even though the first Pascal card won't launch until mid-late 2016 (based on current rumors), this is really old news history.

Of course they're more than experimenting with HBM. I'm wondering how far behind Nvidia is when it comes to R&D with HBM... or if Nvidia is behind AMD at all...

Unlike AMD they didn't bother with 2.5Dram so they probably have more resources into 3Dram(HBM2.0) than AMD does so I would guess there are ahead.

NVidia Pascal is supposed to have HBM memory, so it should not be a big surprise. However, since SK Hynix had to ramp up production to just fulfil Fury's demand, there might be very limited supply. Remember that AMD is going heavy on HBM, included on their 14nm Greenland GPU, and their ZEN APU's (maybe CPU's too). Based on the cooperation between AMD and SK Hynix, I would speculate that they get first choice.

 

They showed it at GTC Iast year here's a high res pic of Pascal:

I wonder how NVidia is even going to make it work, and if this prototype is even functional. AMD had to solve HBM with a silicon interposer, but this Pascal prototype does not seem to use an interposer. Seems "fishy".

 

Either way, if NVidia cannot get their contract signed with Global Foundries soon, they will not be on 14nm FF, but be forced to use TSMC's 16nm FF+. TSMC is not known to be on time for this, so who knows if Pascal will even launch in Q3 2016.

Uh, being sure of TSMC's ability to get 16nm FF+ yields up to snuff is pretty dangerous LukaP.

"the fastest gpu (nvidia titan black)" in the presentation, so it might be so new /s

There's an interposer for the GPU die and the four last level caches in the center. You can attach HBM 2 to the PCB without need of an interposer. Interposers just remove latency and lower power requirements. My question for that picture is what those 4 inner memory blocks are. HMC, or a custom eDRAM/eSRAM cache a la Intel Crystalwell?

It's not a silicon interposer though, but a standard PCB interposer. However interposers also means you can make a full package. Fiji comes as a ready package to install on any PCB, which makes things cheaper and easier to install. Probably also improves yields.

 

And yeah it does not quite look like HBM, so it probably is HMC prototypes. After all Pascal has always been about stacked memory from the get go.

Like everyone said not news and don't know why this isn't moved or locked.

Whatever happened to the Denver arm chip on a gpu?

I just want sub 20nm HBM cards naaooooo. :)

Werent they taping out good wafers of it last quarter? Otherwise, im sure intel wouldnt mind lending some 22nm fabs to them ;) its basically the same process anyway xD
