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.
