The AMD Radeon VII Review: An Unexpected Shot At The High-End
by Nate Oh on February 7, 2019 9:00 AM ESTMeet The Radeon VII
First things first is the design and build, and for the AMD Radeon VII, we've already noticed the biggest change: an open air cooler. Keeping the sleek brushed metal look of the previous RX Vega 64 Limited Edition and Liquid variants, they've forgone the blower for a triple axial fan setup, the standard custom AIB configuration for high-end cards.
While NVIDIA's GeForce RTX series went this way with open-air dual-fan coolers, AMD is no stranger to changing things up themselves. Aside from the RX Vega 64 Liquid, the R9 Fury X's AIO CLC was also quite impressive for a reference design. But as we mentioned with the Founders Edition cards, moving away from blowers for open-air means adopting a cooling configuration that can no longer guarantee complete self-cooling. That is, cooling effectiveness won't be independent of chassis airflow, or lack thereof. This is usually an issue for large OEMs that configure machines assuming blower-style cards, but this is less the case for the highest-end cards, which for pre-builts tend to come from boutique system integrators.
The move to open-air does benefit higher TDP, and at 300W TBP the Radeon VII is indeed one for higher power consumption. While 5W more than the RX Vega 64, there's presumably more localized heat with two more HBM2 stacks, plus the fact that the same amount of power is being consumed but on a smaller die area. And at 300W TBP, this would mean that all power-savings from the smaller process were re-invested into performance. If higher clockspeeds are where the Radeon VII is bringing the majority of its speedup over RX Vega 64, then there would be little alternative to abandoning the blower.
Returning to the Radeon VII build, then, the card naturally has dual 8-pin PCIe connectors, but lacks the BIOS switch of the RX Vega cards that toggled a lower-power BIOS. And with the customary LEDs, the 'Radeon' on the side lights up, as does the 'R' cube in the corner.
In terms of display outputs, there are no surprises here with 3x DisplayPort and 1x HDMI.
A few teardowns of the card elsewhere revealed a vapor chamber configuration with a thermal pad for the TIM, rather than the usual paste. While lower-performing in terms of heat transfer, we know that the RX Vega cards ended up having molded and unmolded package variants, requiring specific instructions to manufacturers on the matter. So this might be a way to head off potential ASIC height difference issues.

This card is a turkey for gamers. AMD fixed the noise level problem with Fury X and now we're getting less value than we did then. It's too loud."Also new to this card and something AMD will be keen to call out is their triple-fan cooler, replacing the warmly received blower on the Radeon RX Vega 64/56 cards."
Is the sarcasm really necessary? If you're going to mention the cooler thing why not point out just how far AMD has regressed in terms of noise. Remember Fury X, a card that is nice under load?
"Vega 20 has nothing on paper to push for its viability at consumer prices. And yet thanks to a fortunate confluence of factors, here we are."
Oh please:
Fiji: 596 mm2 for $650. Vega 10 495 mm2 for $500. Vega 20 331 mm2 for $700.
Anandtech says it's all so shocking that Vega 20 is available to consumers at all. Eyeroll. No. For $700, AMD could have put that extra die area to more use and given us 8 GB of VRAM. But that would involve doing the impossible and making a GPU that is attractive to gamers, not just peddling low-end Polaris rehashes indefinitely.
Consumers aren't getting the best value here. They're getting leftovers just as they did with Bulldozer/Piledriver — parts that were targeted at the server market first and not consumers. At least with Vega 20, though, there is some competitiveness, although this is mainly because Nvidia is artificially crippling the value of the GPU market with its inflated pricing strategy. That is what monopolies do, of course. Look at how long Intel was able to coast with Sandy-level performance.
"At 3.5 TLFLOPS of theoretical FP64 performance, the Radeon VII is in a league of its own for the price. There simply aren’t any other current-generation cards priced below $2000 that even attempt to address the matter."
That's marvelous for the people who are able to care about FP64, unlike gamers.
This is what happens when there isn't enough competition in a market. Gamers get the choice of two shafts: Turing and Vega.

Oh, yes... and the "console".At least the Switch is a real console. I'm not talking about that. I'm talking about awful low-end PCs being falsely called consoles, which has been the practice since Jaguar became an (unfortunate) thing.

like in a previous post of yours.. are you forgetting that the xbox and xbox 360 were also, " low end " pc's that your are claiming ?? the switch is a real console ?? ha.. the nintendo switch, is based off of the Tegra SoC's from nvidia... in a way.. " still " a low end PC......Oxford Guy - Friday, February 8, 2019 - link
The reason the Switch qualifies as a console is that it does something differently vis-à-vis the x86 gaming PC platform. It has a different form factor and related functionality. Artificial software walled gardens do not truly differentiate Sony and MS's low-end PCs from the PC gaming market. They are merely anti-consumer kludge that people have chosen to prop up with their cash.Merely having an x86 processor does not make something equivalent to an x86 PC. The Switch is clearly not the same thing as a low-end PC box like a Jaguar-based rubbish console. I am not particularly enamored with the Switch but at least Nintendo is offering something different to better justify its approach.

this sounds more like your own personal opinion and nothing more.. for some reason you hate the current consoles, and seems like there is NO reason for your hate...nintendo has offered something different for a console since the 1st Wii, and honestly, look where it has gotten them... the xbox and playstation platforms outsold the nintendo systems, up to the switch, which has out sold the other 2.. but the games them selves on the nintendo systems.. are lacking..

"this sounds more like your own personal opinion and nothing more.. for some reason you hate the current consoles, and seems like there is NO reason for your hate..."Ad hominem isn't a rebuttal.

still just sounds like your personal opinion, regardlessHorzaG - Sunday, February 10, 2019 - link
Pointing out that (according to the poster) you're just expressing your opinion and "hate" without reasoning isn't an Ad hominem, you used the term incorrectly earlier in this thread also. Pretty embarrassing to be simultaneously so conceited and so wrong."You should never listen to a word Oxford Guy has to say because he's a frothing fanboy whose posts reek of desperation and are probably indicative of an inability to get laid"
That's an Ad hominem.

and saying this :" You should never listen to a word Oxford Guy has to say because he's a frothing fanboy whose posts reek of desperation and are probably indicative of an inability to get laid "
about someone.. doesnt prove your point any better...

"Pretty embarrassing to be simultaneously so conceited and so wrong."It must be.
