NVIDIA GeForce "Volta" Graphics Cards to Feature GDDR6 Memory According to SK Hynix Deal

[btarunr]

NVIDIA's upcoming GeForce GTX graphics cards based on the "Volta" architecture, could feature GDDR6 memory, according to a supply deal SK Hynix struck with NVIDIA, resulting in the Korean memory manufacturer's stock price surging by 6 percent. It's not known if GDDR6 will be deployed on all SKUs, or if like GDDR5X, it will be exclusive to a handful high-end SKUs. The latest version of SK Hynix memory catalogue points to an 8 Gb (1 GB) GDDR6 memory chip supporting speeds of up to 14 Gbps at 1.35V, and up to 12 Gbps at 1.25V.

Considering NVIDIA already got GDDR5X to run at 11 Gbps, it could choose the faster option. Memory remains a cause for concern. If 8 Gb is the densest chip from SK Hynix, then the fabled "GV104" (GP104-successor), which could likely feature a 256-bit wide memory interface, will only feature up to 8 GB of memory, precluding the unlikely (and costly) option of piggy-backing chips to achieve 16 GB.

i knew it would be volta!! haha

 

[Prima.Vera]

The GTX 1180 (2080 ?) will most likely have a 256-bit WMI and 8GB of GDDR6(?), probably at 12 Gbps, while keeping the 14 Gbps for the Ti version...
It's cool, since the memory is not the performace bottlenecker anymore.

Yea thats how i have it in db 12gbps for 1180 14 for 1185 16 can be for next gen

its 100% 11 series too

 

[eidairaman1]

So is this going to be exclusivity against AMD or will Hynix allow them to use it as well?

 

[bubbleawsome]

Hm what if they go slower (12Gbps) and use a 384-bit bus for 12GB

 

[Nkd]

i knew it would be volta!! haha

I think the article is guessing about volta portion. Nvidia next cards are apparently based of Turing. Who knows if its based of volta I am sure some features are but rumor is might be just an evolution of pascal since there is no competition by amd this year. We all knew it was GDDR6 on the next high end cards but the volta portion on this write up is just speculation.

only Volta is on Nvidias timeline, they wouldnt waste an architecture for one chip. they have already cut it down and Turing is speculated, only gamers nexus heard it was real but probably for mining.

literally every site thinks its turing based on nexus nothing else.

Upping bus width is expensive; I don't think that NVIDIA would put that in their high end GPUs (GV104). More likely GDDR6 on a 256bit bus. 12gbps chips on a 256bit bus will net 384GB/s, which is respectable. If they go with 14Gbps on 256bit bus it'll net 448GB/s.

Memory is the bottleneck for Volta

It really throttles the Titan Volta and even OCing the HBM2 by 25% to 30% is not enough.

Having said that GDDR6 for gaming may be more suitable than HBM2

How does memory throttle Volta? If you look at games, Titan V isn't much better than 1080ti up to 1080p, gets a little better at 1440p, then starts pulling away at 4k.
If anything, the higher resolution should hurt a memory starved chip. Just like how HBM helped Fury X at higher resolution, when it stumbled at 1080p.
Saying Titan V is throttled by its memory requires some significant analytical proof (given it uses HBM2).

Yup. Im gonna pm you with a theory to not clutter this thread up

1080p throttles a lot of top end cards due to the CPU.

Yes the Titan V does pull away at 2160p but that does not mean that the memory is not throttling it.

The Titan V is a brute of a card for performance in gaming but it would benefit from faster memory.

Ultimately HBM will be the answer but it will most likely be version 4 or 5 where the clockspeed is high enough to keep up with fps.

Whole point of using high speed memory is to avoid using wider memory bus. It's cheaper to slam slightly more expensive and faster VRAM than making chip with wider memory controller.

It's gonna be very disappointing if the new flagship uses only 8GB of memory @12GHz

but 12GB/16GB @14GHz should be fine.

Yeah Turing, Ampere and Volta lol I keep thinking what's next? Schrodinger?

You forgot Tesla ….

 

[agent_x007]

With Schrodinger as GPU codename, there is a chance it will be like Duke Nukem Forever
It's out there, but it's not.

Einstein ?
Planck ?

Tesla = G80/GT200

 

[gmn 17]

16GB or BUST

Wouldn't that be like saying I forgot GeForce?

I do not expect Nvidia to massively improve but respectable improvements and much awaited.
I expect AMD to massively improve in gaming performance (like it could get worse? vega56 is the only great card in their entire lineup with hardware vs cost vs performance (MSRP!!!))

If so life won't be so bad, competition reduces prices

GDDR6 just isn't a good enough improvement and they have to increase width to make up for it which drives up the cost and then we're not getting bang for our buck.

I don't think Pascal was after Maxwell on a older roadmap either. Its subject to change apparently.

Memory bandwidth is one of the primary concerns for any GPU design.

And it's only going to get funnier when, because of HDR, we move to 10 bits per channel. 25% more bandwidth required right off the bat.
