AMD Vega 10 GPU Name Accidentally Confirmed as Radeon RX 490 gets 8GB
Well, it's not like it was exactly a secret but thanks Bethesda for confirming it. Bethesda announced it will release a new HD Texture Pack for the PC version of Fallout 4. To prepare PC gamers for this upcoming pack, Bethesda revealed the system requirements for it, and guess what they listed?
And it appears that the big publisher has leaked the name and the amount of graphics memory (8GB) that AMD's upcoming Vega10 GPU will feature. According to Bethesda, these are the official requirements for Fallout 4’s upcoming High-Resolution Texture Pack.
Recommended PC Specs
- Windows 7/8/10 (64-bit OS required)
- Intel Core i7-5820K or better
- GTX 1080 8GB/AMD Radeon RX 490 8GB
- 8GB+ Ram
Meanwhile in a new updated HBM2 specifications document released by SK Hynix they confirm HBM2 specs and availability of 4 gigabyte (32 Gbit) HBM2 stacks in Q1 2017. If you look at the photo below you can see two HMB2 stacks :) Radeon "Vega" thus indeed has 2x 4 GB HBM2 stacks, 8 GB of total memory.
If you dig a little deeper into the document you'll notice SK Hynix H5VR32ESM4H-H1K at 1.60 Gbps (per pin), with a cumulative bandwidth of 205 GB/s per stack. x2 is 410 GB/s of memory bandwidth, if AMD sticks to the reference clock on this memory

Fingers crossed that it will be at least as competitive as gtx 1080, otherwise big disappointment.

If it's on par with gtx 1080, and so late released, that will be a big disappointment!
The only thing that will make people buy it will be the future performance increase due to drivers and better dx12 support, but by then NVIDIA will have another card out.
It has to be on par with 1080ti or big Pascal to be a game changer.

I don't get why people think this. Unless you have a 144Hz 2K monitor (or some other uncommon monitor setup), the 1080 doesn't make sense: it's not good enough to play most modern games at 4K with max detail, meanwhile the 1070 can play just about any game above 60FPS at 2K with max detail. I'm all for healthy competition but the 1080 is niche even for enthusiasts.
What I think is more important is if it can handily outperform the 1070 while using at least 50 fewer watts. A GPU that can outperform the 1080 would only be worth buying if it can do 4K gaming, which for AMD would be a weirdly huge performance gap between the 480 and 490. Even the performance gap between the 460 and 470 is uncharacteristically large for AMD. If AMD makes another Fury, that I think is what should focus on outperforming the 1080.
Anyway, if you don't have an obscure display setup, then clearly all you care about are getting bigger numbers for the hell of it. If that's the case, why don't you personally have a better CPU, or 2+ 1080s?

Price wise, Vega 10 is basically capable to be cheaper than Fury X to produce. (Bigger margins.)
Take it this way:
While it has 8GB of HBM2, it needs only 2048bit IMC instead of 4096bit IMC on Fury/Fury X. (And yet it has same basic bandwidth.)
And that means bit cheaper interposer too.
My humble guess is that RX-490 will have 225W Power consumption and will run at 1350~1400MHz.
With changes in architecture I expect it to be up to 45~50% faster than Fury X (Mostly due to clock.)
And Power efficiency improvement: 1.5 / 1 * 300/225 = 2
So I expect 2x performance per Watt over what Fury X delivers.
Tbh if it is 12tflop part it will be somewhere around 1500mhz no way around that. Also it should have better IPC then Fury or Polaris cards. And all in all improved anyway.
