Videocardz has gone on my "roll eyes" list. They oversold Polaris. Gonna wait and see what AMD or a site I trust more comes up with.

But here is hoping my next card is a Radeon!

EDIT:

I bit, reading their article their opener is a good sprinkle of salt.

This buzzword cloud reveals that VEGA has 2x peak throughput per clock and 4x higher power efficiency. What we don’t know is what was compared to VEGA.
If they are comparing it to Polaris, yawn. If they are comparing it to Fiji. My ears are perked.

EDIT #2:

Hmmm.... Radeon Vega? Why does that not sound as appealing? AMD adding yet another new name to their stack? Will they not use Fury this time?

Several Easter eggs in the video including a "poor Volta" poster.

If AMD delivers, my 1070s are out the door! Hoping for 45-50% gain over the Fury X at 4K. Fingers crossed for 4096 shaders @ 1525mhz = 12.5Tflops FP32.

About the "High Bandwidth Cache Controller" thing. Do you remember this:



Could this be the first usage of an active "Base Die"?

A Radeon SSG comes to mind, where the SSD would not be addressed by PCIe, but directly over the GPU PHY ...

While fury ended up being solid products the name was tarnished so starting over a with a fresh name would be good.

A straight up die shrink of Fury from 28nm to 14nm should yield at least a 30% gain. If it isn't a 40%+ gain, then its a disappointment.

Hope videocardz is right about the rasterizer improvements.

May get a Vega GPU, from 480, if it has enough rasterizer changes to comply with DX 12_1.

Pretty excited to see what AMD brings to the table. Crossing my fingers they have a solid competitor to the 1080 or even the Ti/Titan XP as I'm itching to upgrade

how accurate is this picture?

As far as I remember this was discussed already almost a year ago in the polaris threads due to AMD patents. So simplified it's probably true. AFAIK the main content of the patent was that you can combine the blocks (except the single block) together into 1 block as well to get a 16-bit wide SIMD. So 1 CU in this case can do 1 16-wide + 1 2-wide SIMD or 1 8-wide, 2 4-wide 1 2-wide SIMD at same time. I think the 2 4-wide blocks can also be combined to a 8-wide block but not sure about that.

EDIT:

It's explained well in the reddit thread the image is from

I'm more concerned about whether they are replacing Polaris 10. Reason being, I have just ordered an RX 480 4GB, and it gets delivered tomorrow. Should I return it and wait for Vega?

Budget won't stretch for anything that has GDDR5X or HDM2.

They are not replacing Polaris, Vega will slot in higher in their line up. They will continue to sell P10 for at least another year (it might get rebranded at some point).

The impression i get from this, is that with the standard 4x16 wide simd units, and one does not utilize all bits in a simd unit, all those transistors still have to switch.
That consumes current and wastes power. With variable length simd units, there is less dissipation if part of the simd unit that is not used is left idle for example with clock gating.
Thus less dissipation, and more thermal headroom thus more boost clock headroom. AMD is with Polaris and Zen and Vega fully into the thermal headroom mantra.
If the chip is cool enough, clock it up until the maximum allowable clock. The idea is similar to what cpu's do. When only 1 of 4 cores is 100% utilized and the other 3 are less utilized, the cpu will boost the clock of that core to the maximum allowable clock until the cpu core reaches the thermal limit.

p.s.
Of course, this is already available for some time on gpu and cpu designs.
If the text above is really the case, AMD refined it a lot. Sensors everywhere on the chip...

Probably won't see any new additions at least until late summer for a refresh of polaris. Though I'm hoping the Vega architecture can spart price wars at all price points, and therefore affecting mid range segments, where I can snap up a cheaper RX 470 or 480.

Well, if the drum represents a single gpu, then a warehouse full of them would imply stock sufficient for a release is available now. Given Vega has been announced and publicly demo'd already ...at the New Horizon event ...then why would AMD be counting down to 'just' another announcement?

Still, the hype train doesn't need any more fuel, least of all from me! :)

Will your budget at least stretch for an 8gb 480? If you can find a deal, return the 4gb card for an 8gb 480!

Vega--at least this initial release--is a higher-end line that is not replacing P 10, and will probably be 3+ months away, anyway.

AMD received first vega samples from fab around december. There is no way vega will be released in q1.
