We're now starting to get detailed rumors/specs. Here's one link from many:

https://www.kitguru.net/components/...ts-to-three-rx-vega-cards-vega-xtx-xt-and-xl/

Seriously. Those power requirements are laughably bad. Too bad that it removes most cMP pro owners from even considering. The Vega RX is officially dead from cMP owners if that's true.

If you don't want to click on the link: The lowest Rx card (Vega RX XL) is rumored to require 285w of power. My guess: It's likely that this card would compete in-between the GTX 1060-1070 based on what we know from the Frontier Edition and leaked 3DMark RX scores from its bigger brother. That's laughably 100w more than what the GTX 1070 requires. That means it's basically not supported by the cMP.

What is going on with AMD? They haven't learned to design efficiently so instead they just require more power to do what nVidia does, and not even likely surpass them?

Gawd. I'm going with a GTX. Vega, you're dead to me unless you prove otherwise.

Bring on the Volta, nVidia, and seal the deal at this point.

1) that's a cantonese link

2) can't see that OP's attachment without login

I don't think that's a proper link to share at here.

Noted mates, I got too carried away seeing the actual Vega card. I will refrain myself from posting irrelevant links in the future.

Sounds like the rumors from when this thread was posted is matching up to be true.

These are awful GPUs for the cMP.

nVidia is touting that "wow, you cannot see any difference between the GTX and the Vega" events. But everything is suggesting that the best RX Vega will require 100 watts more (out of spec for the cMP) than the GTX 1080 and match it. Well, that's not good at all.

Has anyone heard any different, or is Vega dead at this point for us gamers who do not want to treat their cMP's like science?

This disturbing performance trend was noted in the password cracking community years ago, and all serious crackers left AMD for Nvidia for exactly this reason initially. Lack of certain instructions also made Nvidia way faster in certain situations.

Looks like it's absolutely continuing.

Maybe it's just my opinion, but if you want to game seriously on a 8.5 year old machine, you might need to make some hacks, seriously.

My R9 290X pulled 350Watt at 1150MHz, games run just fine at 3440x1440, I went for the powerleads, but you could just as well put an extra PSU in front of the PSU.

290X should be 275w on paper. My 295x2 can run at 350w undervolted.

Who cares what retail boards look like? The "best" looking ones advertise how many juvenile LEDs they feature and you can't see it in a closed mac pro case anyways. That blower trying to dissipate 300 W is going to sound like a vacuum.

Question: what's the wattage required on the Vega FE? I thought it was cMP compatible last I heard.

I also have to ask for those more knowledgable than I am, does anyone know what flaws or faults of the architecture might make the card perform so poorly per wattage?

In what cases?

Take your pick?

Are you just intentionally being difficult here? There are numerous examples of the Vega FE being unable to beat a 180W GTX 1080, and even some where it can't beat a 150W GTX 1070.
<facepalm>

I was asking what Cases he wants to be described from low-level of architecture...

Yeah, it is always me attacking others.

The ones that perform really poorly, per his original question? If you know so much about the architecture, aren't you in the best position to pick something to describe?

There are two possibilities.

I can write a wall of text that nobody will care about reading, or I can focus on specific cases, and specific things.

Hence the question: which cases.

May be you can pick the case that easiest to understand and explain to us.

TBH, I don't even know how to ask properly, I know almost nothing in this area. But also wonder why the recent AMD chip's energy efficiency is so low in high end card.
