MSI: Radeon RX Vega needs a lot of power

And how have you come to that assessment? Can you show me the source of your information please?

It's like the Fury X, it actually has more power than the 980 ti but it turns out that under particularly serial workloads, the GPU tends to be starved of work and performs badly.

From what we know of Vega, most of the bottlenecks in Fiji have been ironed out and if polaris performance is anything to judge by, it should perform rather well or at the very least, comparatively to the 1080 range.

It's still too early to draw conclusions, all we know from this news statement is that Vega needs a lot of power, it doesn't tell us how efficiently Vega is going to use that power, if it's like the Fury X, then yes, it quite possibly could be disappointing and conversely if it shows similar performance scaling to polaris, we might be in for a treat.

Tl;dr wait for reviews before making snap conclusions.

Not that I agree with him but he's probably judging the performance on the several video's over the past 6 months that show Vega performing between 1080/1080Ti levels.

Also, slight update from the MSI guy is a continuation of his posts:

Someone replied:
That aint a positive sign.

To which he replied:
That depends on the level of performance...

In case people didn't know either, multiple sites are listing the WC Vega FE edition at 375w and the AC at 300w.

Which is where the rumors of it being relatively high power came from.

I'm not sure what is disappointing, I mean whats a lot of power 250 watts? Really not one iota of facts here so I wouldn't be disappointing. If it uses 1080 ti power and is a bit faster you probably wouldn't be disappointed. So who the heck knows if this is bad or good.

Perhaps:
Vega 375w performance like gtx 1080ti.
Vega 300w performance like gtx 1080.
Vega 225w performance like gtx 1070.

Until we have them, we will not know.

Interesting, AMD's TDP ratings on the 580's were really close to actual wattage draw so if that is the case here, yeah those are needing some serious power.
