AMD Vega 10, Vega 11, Vega 12 and Vega 20 Rumors and Discussion

.

I believe typo ... i think they have just take the articles posted elsewhere. (TPU etc )

 

Yes it seems it is based on a false rumor, sorry

 

SK Hynix updated its databook with the latest information about HBM2 and GDDR6 memories.

Something about Vega being teased for today by RTG head Raja Koduri and Sr. Marketing Director Chris Hook, as per some previous rumors:

Anyone reading this topic has become well aware of how you choose to interpret or form an opinion about the oncoming information (inclination is always the same).
But it's the jabs like this one I'm replying to that seem to really bring out the true nature of the whole thing.


So all those leaks showing 1200MHz core clock for Vega in early benchmarks are valid and you were convinced Vega couldn't clock over 1.3GHz. However, this last Compubench public score showing 1.6Hz core, together AMD showing slides claiming Vega is optimized for significantly higher clocks and their own Mi25 card being announced with 12.5 TGLOPs FP32 are all probably bogus.

Beginning of Micron's GDDR5X mass production was kept a secret until the formal announcement of the GP100, but 8-Hi stacks HBM2 being made by SK Hynix can't possibly be true even though there's a Compubench score of a Vega card showing 2 stacks of 8GB for a total of 16GB VRAM.

Apple made AMD hide the full Polaris 11 @ 35W from their portfolio so only the cut-down and lower-binned chips (destkop RX460) could be mentioned until the formal announcement of the Macbook Pros some 3 months later, but for you it's impossible for SK Hynix to hide 2Gbps HBM2 for a couple of quarters to give AMD the chance to formally present it to the public - even though it was already in their portfolio.

 

On the follow-up of the previous post, today is analyst's day and anyone can follow it here, at 1PM PT <-> 9PM GMT:

If only for this part, I just would have clicked "Like" on your post.

 

This is interesting, hope all of it is true. 1600MHz core clock and 16 gigs of HBM2. Although 16 gigs of vram is a bit of an overkill for games it might be very useful for other applications

 

1600 core or boost clock?

 

But I guess, with HBM2, it either that, or "only" 8 ? They can't go 11 or 12 like nVidia, right ?

 

The info tab at compubench.com says:
„CL_DEVICE_MAX_CLOCK_FREQUENCY 1600“

 

Hence why i will have first think that thoses benchmark are linked to the MI25 or a similar card.. 16GB should be the minimum for this type of card.
Now is there a possibility that the MI25 have a 4Hi x4Gb stack ( so different interposer ) that the Vega 10 "gaming part" ? ( or basically this could explain too why vega 20)

 

Yeah right so secret....
Here is what I said 2 days before the Micron announcement 10th May announcement (which was 4 days before the PCGamer 'news about secret production' 12th May) and my info was referencing information that went back months before that with it having production status and contact for order:

May 8th 2016:
https://forum.beyond3d.com/threads/nvidia-pascal-announcement.57763/page-33#post-1912442

Production status means available to calendar order.
12Gbps never made it further than Sampling status for a long while (unfortunately only hit production status around March 2017) and so my expectation on that was wrong, but shows reality and challenges of ETA/estimated spec into official catalogue or the parts reference and then importantly to Sampling status, and then critically to Production status.

And I said it looked more likely the clocks would be 1300-1350MHz for the reasons I gave, not as you infer that it would not even hit 1300MHz.
And this is sustained 1300-1350MHz rather than as I pointed out (either that post or earlier) what happens with Nano relative to its official TFLOPs/Boost that is not sustained or only very briefly hit unless one overclocks/tweaks it.
This is ignoring the massive power demand it takes Nvidia to push the 1080ti even towards 1900MHz (post you were referring to also was considering relative clock changes) and this is a smaller core/die than Fiji in an area Nvidia is well known for efficiency and operating at high clock speeds across all GPU sizes.

Anyway back to current subject, Micron GDDR5X production status or contact Micron for order was never kept secret to tie in with Nvidia product.
Nor would I expect SK Hynix to keep it secret when it comes to their catalogue/parts reference that goes to end of year for schedule and ordering, both would do announcements that aligns with products using their component but that is different to the parts book.

But happy to drop this until we get the facts from AMD rather than 'leaks'.

 

Will the price of HBM2 ever experience economies of scale if Nvidia decides to stay on the GDDR path for consumer cards? With Samsung and Micron ramping up GDDR6 production the likelihood of widespread standards acceptance/rollout and lower prices for HBM2 seems less each day.

 

Unless there are other products in which AMD, Samsung, Intel... could implement HBM (HPC, servers, workstations, ultra portable laptops, SFF PCs, mobile devices...).

 

As mentioned a couple of pages ago, with HBM's interposer requirement, AMD isn't selling only the GPU in a substrate to OEMs.
AMD is selling the GPU, the HBM stacks and the Interposer all in one package.

AFAIK, there are only two companies with HBM in their roadmaps: AMD and nvidia. Nvidia for GPUs, AMD for GPUs and APUs.

So if an OEM wants to build a Vega graphics card, they have to buy the GPU+HBM from AMD. If a HPC builder wants to use high-performance APUs with HBM, they'll have to buy APU+HBM from AMD. Same thing for a laptop maker if they make a Raven Ridge successor with HBM.

Intel's architectures don't support HBM and aren't likely to support it in the future either (unless their own HMC really crashes and burns).
There are talks about Intel planning a MCM carrying a Core ix and a Radeon GPU, but if said GPU uses HBM then it needs to come in an interposer so again AMD would be selling the HBM together with the GPU in the interposer.


HBM isn't tailored for handhelds either, as its JEDEC ultra-low power counterpart is Wide I/O.

The only possible candidate for HBM is company trying to build an ARM-powered HPC/server chip using that memory, but ARM chips haven't been awfully popular in that area.
Perhaps if/when apple decides to ditch x86 and replace them Intel cores with their ARM windy stuff, they'll be looking to use the best-of-the-best in for their high-margins laptops and AiOs. But that's still a long time away IMO.





So the short answer to your question is: no, there doesn't seem to be anyone else other than AMD wanting to buy HBM from SK Hynix at the moment.

 

Samsung announced a network processor with HBM2 recently, and that type of high-speed signalling chip is a target for HBM2.
As far as Intel goes--or technically its Altera acquistion, the Stratix 10 was announced with HBM2 and at the time it was supposedly from Hynix.
Intel's Lake Crest uses HBM2, but that is also from another acquisition.
HPC and networking were targets for HBM2, and at least some work has gone into that.

The original HBM appears to be even more limited to AMD's last-gen hardware.

 

I think it's clear that no one who visits this forum has any idea of current HBM2 production and stock. Let's try to focus on vega's architecture.

 

Stream where VEGA will probably be unveiled (one hour segment dedicated to high-end PCs + Radeon): http://webcastevents.com/events/amd/analystday/live/player.htm

It's live right now.

 

More likely is that they'll announce when it will be unveiled

 

They've just said on stream they will be showing demos, hopefully it's not DOOM again (don't have anything against it but we've seen that already ).
