[News] AMD to announce Vega tonight [Update: Vega Computex Announcement]

Useless thread.

Useless post.

If you consider this thread useless, the door is open and the dogs are all tied.

It is not consideration, it is a fact.

Not all are capable to "get" it, though.

And btw, just to throw the last tidbit of quality, AMD crаp gonna be offered in 2 versions vega 10 and 11. Computex had 10 running. 11 is coming at a later(quiet a bit) date. So if someone here wants performance, better buy NV here and now and stop listening to all these BS sht about volta. It is a very long time till it will come out.

Stick around with LordEC911.
I'll definitely call you up upon this.

By the way, Q1 2018 is far from very long time

6-8months ? Eh. I consider it a long time.
Its still to be seen how much better volta is going to be(than pascal). Things arent really what they seem.
I just want to know, what went wrong with vega, maybe its still fixable.484mm2 chip, on 14nm. Thats a big ass chip with absurd power consumption, and performance nowhere to be found.
I mean if they would shrink hawaii and make it bigger a bit faster and give it the same 300W tdp it would be faster.
Polaris is more than half the size ! And has slow bandwith.

From my understanding, in the short version, the main problem is that AMD bet big on HBM2 and it back fired.

See below, for more details on the long version: Some info taken from Nvidia's SC15 GPU Tech Theater

On further explaining the next generation GPU architectures and efficiency, Stephen pointed out that HBM is a great memory architecture which will be implemented across Pascal and Volta chips but those chips have max bandwidth of 1.2 TB/s (Volta GPU). Moving forward, there exists a looming memory power crisis. HBM2 at 1.2 TB/s sure is great but it adds 60W to the power envelope on a standard GPU. The current implementation of HBM1 on Fiji chips adds around 25W to the chip. Moving onwards, chips with access of 2 TB/s bandwidth will increase the overall power limit on chips which will go from worse to breaking point. A chip with 2.5 TB/s HBM (2nd generation) memory will reach a 120W TDP for the memory architecture alone, a 1.5 times efficient HBM 2 architecture that outputs over 3 TB/s bandwidth will need 160W to feed the memory alone.

Hold on. HBM was supposed to be the "power saver" for the GPU memory architecture.
Anyhow, we have 484GB/s on vega, so thats less than half of this 60W power figure, that would put HBM power consumption in vega at around 30W maybe less.Thas less than GDDR5/x/6.
And The cards are supposed to eat up 300-400W. HBM doesnt really explain Vega for me.
Fiji had 4 stacks of HBM1, Vega has 2 Stacks of HBM2 at LOWER bandwith and still eats anyhwere between 25 and 100W more than Fiji! Something more is wrong here.
I know that HBM2 availability was a thing that surely went wrong for AMD. But i dont know about the power consumption and performance.

That's the key..."supposed to" is turning out to not. One of the two main reasons nvidia hasn't switched to HBM2 for consumer grade products availability and power consumption. It's shown right in the link directly from nvidia this was a major concern for them.
