AMD Vega GPU Features

As I said more than half a year ago, Vega's delays are largely tied to HBM2. Yields aren't where they need to be and costs are prohibitive. Heck, even HBM1 yields are still in the tank.

I know this will likely cause some controversy but I think the high end RX Vega is in serious trouble if AMD decides to stick with HBM2 (which they will of course). I know that statement may come out of left field but SKHynix -a key HBM2 partner- has already telegraphed that GDDR6 will be their go-to product for high-end GPUs.

They've gone so far as to confirm that GDDR6 is nearing mass production state AND a high-end GPU product will be launching in early 2018 with the technology. That would likely be the GeForce version of Volta.

If that is the case, remember that Gen 1 GDDR6 is supposed to offer speeds of 16Gbps. Add that to something like a 384-bit interface and you get 768GB/s which dwarfs even the most optimistic 512GB/s spec for HBM2 and you have a very scary situation for AMD wherein their flagship GPU doesn't ever attain its fullest production potential due to a bottleneck in memory production / availability.

I think I'm just going to settle on the Rx 580 for now, what you're saying makes sense and doesn't look hopeful to me.

That is interesting insight but I don't think that is something any of us want to be true. If AMD really gets themselves into that situation then my dream of cheap 1080Tis is gone!

Seriously though I think even those locked into NVIDIA, like me with my expensive G-Sync monitor for example, still want AMD to be a winner as we have said over and over on these forums to promote competition and better pricing. If AMD did make that big a misstep with HBM2 then we're not going to get that. At least Ryzen and the Threadripper stuff seems to be a contender in the CPU arena.

The other thing about the new AMD cards not coming until late July is that I think there will be a lot of people who just won't wait that long. The 1080Tis will have been out for a good while with a proven performance record and I think people will just say "Meh... I'll buy for the performance now." Maybe people are more patient than I think (or perhaps I should say more patient than me)?

Prepare your PSUs : 2 x 8pin power leads are required to drive a Vega GPU with a stated TDP of 300W for the air cooled version, going as high as 375W for the water cooled versions. Cost : 999$ and performance of a 1080, not a 1080 Ti. Base clock of 1328 MHz with boost up to 1600 MHz. https://www.techpowerup.com/234573/radeon-rx-vega-needs-a-damn-lot-of-power-aib-partner-rep
From what I have read it is going to be high power, but I think the price you quoted is for the professional GPUs, not the gaming ones. I may be wrong though.

As weird as is sounds, but finally proper enthusiast grade balls-to-the-wall stuff which doesn't give a rats ass about power consumption or heat output. Technology and engineering pushed to the absolute limit.
That's why we have all the board partners to build those ridiculous heat-pipe galore coolers, that's why we have 1Kw+ PSUs. Finally will get to pull the unused PSU cables out of their bag. :biggrin:

That was the 295X2 :thumb:
