MSI: Radeon RX Vega needs a lot of power
Over at some Dutch forums MSI Marketing Director Eric Van Beurden made a bit of a slip of the tongue. In a reaction (written in Dutch) he commented on the specs of the consumer edition(s) Radeon RX Vega.
So he wrote this :
I'm Dutch, my translation would be spot on. He states, I've seen the Radeon RX VEGA specifications, "dang that product needs power". He then states that MSI is working on the card and a launch is pending (which is a bit of an open door alright). He does not mention any detailed specs though.
But board partners thus ARE working actively on Vega and well, we already know that these cards sit in the 250~300 Watt board power region. Perhaps higher?

Most pre overclocked board partner are in the 300W+ range ( 318W for the MSI ).. But the " standard " version, at least in games are under ( 280W ) ...
Now max board power ( based on the 2x 8 pin PCI epxress+75W PCI express ), dont forcibly mean the card use 300W+ ( 350W in the case of a 2x 8pin connectors ... ( 150x2 + 75W from the slot )
The MI25 is allready rated at 300W..
Doesnt the 1080 ti draw something like 400w when under load?

Guess I'll just keep my OG TITANs in Quad SLI. I was looking for an "all AMD" system on the horizon...

If it's anything like polaris we can expect poor perf/watt compared to pascal.
Example RX580 vs 1060 6GB uses 40% more power for the same performance.
Also despite having higher theoretical Tflops the 580 has over 1060 it still performs the same averaged across many titles.
Vega really needs to destroy the Ti to have any saving grace if rumors that it's a power hog are true.
Tflops are not equal to gaming performance, that's the AMD problem.We didn't see FPS counter for a good reason in hype videos lately...
As we know Nvidia TFlops give more gaming performance than AMD Tflops:
GTX 980ti has 5.63 TFs and Fury X has 8.6 TFs.
GTX 1080TI delivers 11.4 TFs, Vega Frontier 13 TFs, Vega Gaming in July/August (?), vega 56 11 TFs, Vega 64 13 TFs.
Let's see AMD drivers, i expect the worst.

Yeah but we also know the reasons why AMD's Tflops don't equal Nvidia's in game performance and Vega's changes were supposed to remedy most of those issues (architecture balance/drivers/etc).
I still personally think the top end Vega will trade blows in various games with the Ti, especially at higher resolutions. I just don't know if the year and 3+ months of architecture design that Vega has over Pascal justifies what would essentially be a tie. I'm kind of on the fence when I think Volta will launch. I assumed it wouldn't be until 2018 because I thought GV100 was going to be delayed.. but it's pretty clear that GV100 is going to be shipping ~Q3.
https://pbs.twimg.com/media/DBJY-f8XoAAbaZA.jpg - they already have them shipping to select partners in test servers.
So now I'm thinking Nvidia might just move the launch of Volta up to sometime this year. I don't think they'll put out a 600mm2 card, but if they did put out a ~400mm2 GTX1180 @ 180w with 10-15% more performance than the 1080Ti (Kind of like the 1080 to the 980Ti) - it would definitely hurt Vega sales.
AMD would have to wait for a 7nm refresh of Vega(20). Problem is Nvidia is also moving to 7nm next year but they are using TSMC's process which is rumored to be 6 months ahead of Samsung/GFs in terms of full production. So I'm not quite sure how that will play out or what Nvidia would even launch at 7nm ~August 2018 timeframe.
IDK, things are definitely going to get interesting for AMD though. Especially when Navi rolls around, which I think is going to use a similar paradigm to multi-core design as Epyc/TR is. Multiple smaller dies connected by infinity fabric. How they will do the scheduling/memory management, idk, HBCC maybe? But it's definitely going to be cool - but won't be around till 2019.

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.
If it's anything like polaris we can expect poor perf/watt compared to pascal.
Example RX580 vs 1060 6GB uses 40% more power for the same performance.
