Radeon RX Vega to be Air and Liquid Cooled - XL XT and XTX models
So the title it actually nothing new, everybody knows that Radeon RX Vega will see air and liquid cooled parts, but over the weekend some new data surfaced on the web, detailing the different SKUs a little better in ther form of a flagship LCS AMD Radeon RX VEGA XTX, an aircooled XT and then also an XL version.
Basically the Vega XTX is the water-cooled edition of the air-cooled XT with a higher TDP. There now also is a rumored XL model with cut-down Vega, much like what AMD has been doing with the Fury series. XTX and XT will feature 8GB HBM2 memory. We do not think a 16GB model is planned. Here is the latest rumored table that shows the SKUs:
| SKU | Shader cluster | Storage | cooling | ASIC Power | Board Power | remark | Launch |
|---|---|---|---|---|---|---|---|
| Radeon RX Vega XTX | 64 shader clusters = 4096 shader units |
8 GB HBM2 | AiO (water) | 300W | 375W | Reference | (Presumably) early August |
| Radeon RX Vega XT | 64 shader clusters = 4096 shader units |
8 GB HBM2 | air | 220W | 285W | Reference | (Presumably) early August |
| Radeon RX Vega XL | 56 shader clusters = 3584 shader units |
? GB HBM2 | air | 220W | 285W | AIB design | (Presumably) at the end of August |
As you can see the XT and XTX are tagged at 64 shader units x 64 shares = 4096. The XL model gets 56 shader untis and thus 3584 shader units. The chart also is listing TDP and TDB powers. It is expected that a 1.7GHz GPU clock is likely what the boards will run at. If correct and with a Boost to say 1800MHz, Vega would get respectable performance and would put the card in the range of the GTX 1080.
AMD Radeon RX Vega series will be unveiled at SIGGRAPH Capsaicin on July 30th.

Because it was just the return pipe from the water block flattened on one side and taped to the VRM's the water was moving over it too fast to do any real heat transfer. VRM temps where reported in the 90's at default in some reviews. While that is within safe temperatures for the VRM it does seem very high for a water cooled card. In fact most AIO cooled hybrid cards with a blower fan going across the VRM's do good as well.
I thought the Fury X had a heatpipe over the VRM's that connected to the Waterblock ? It should have been pretty cool, I would have thought...

Lets just hope the AIO doesn't suffer from the whine the Fury X one suffered from, as everyone will be going for that, instead of the one with that crappy FE blower cooler on it

I'd go for the blower cooler and slap a full cover on it personally.
BTW what happened to that nice small PCB that Fiji had. This card is as big as a GP102.

All of these crybabies crying about TDP.
We are enthusiast, not green power users..
Crying about the power usuage of a gpu, but many of you have a heavily overclocked CPU. Yes while the power usuage is lower on a cpu, i find it hilarious irony.
And the Fury X had a heatpipe over the VRM that was part of the AIO.
There was no VRM issues on the Fury X. I had one.
The power usage is important when in context to the rest of the chip. If RX Vega performs 20-30% faster than 1080Ti across the board, I don't think anyone would care about the power usage. But so far all FE testing indicates Vega will perform roughly between a 1070/1080 and using almost double the power to get that. And what's even more troubling is that Nvidia claims Volta is getting an additional 50% perf/w increase. Which means a GV104 with the same specs as a 1080 would be like 120w, vs the 350w of the Vega FE WC that only hits 1080 performance in like 1-2 games.
And I get obviously that a lot of this is subject to change with driver updates, bios changes, potential hardware changes with RX Vega - but so far it doesn't look good for the architecture. It also doesn't look good for AMD's margins - having to drop a liquid cooler onto a card you can only sell for ~$500 at the most while also having more expensive HBM2, definitely isn't ideal.

It's a throwback from the original naming convention used by ATi, XTX being the top tier model, followed by XT and the XL being the value version of the top card.
Remember the 9800XT? X800XT or X800XL? Or the X1950XTX etc.
