Since when is power not a factor?
If the GPUs are otherwise close to equal, I am going lean heavily toward the one using less power.
If one draws a lot more power, there better be some kind of counter advantage to offset that.
Heck even when I am looking at upgrading to a GTX 1060 vs Polaris, I prefer the GTX 1060 because of power draw and I have a 600 W PS, even more now that RX 580 uses 8 pin (or 8pin + 6 pin) power and GTX 1060 uses 6 pin. My PS has dual 6 pin connectors, no 8 pin.
Using more power is a negative, and unless there is something balancing that on the other side it definitely factors into my decision.
I have it the same way.
What i will do for my rx64 is trade some temp and perf for far better efficiency.
Surely this vega looks very bad and deserve some flak. But if we go back to the 780ti launch things were not so so bad but nearly. The 780ti was clearly much faster than the 290x that sounded like a jetplane and sucked up power.
We tend to forget how bad the refefence 290x looked here.
Go back and look at the discussion we had back then. The 290x was hammered.
Time were very good for the 290x. Very. We know that.
I dont think vega will fare nearly as good but there is clear facts for perf that defenitively points the right direction. And its near future imo. And power can as i showed with tpu rx 56 review pretty much be solved. The bashing of this gpu is a bit over the top.
I think the problem will be availability and thereby price. The problems goes far beyond the arch.
If its priced over their counterparts it clearly doesnt make sense.
But so what. Then you just get a gpu with another name.
Its an utterly useless gpu for mobile but its amd problem. Mm2 and hbm2 the same.
I seem some people will better support amd. It makes no sense. In reality its supporting mubadala. An incompetent investment fund. Buy the gpu that solves your need.
