It is not the first time we talk about the possible versions that will have AMD Radeon RX Vega, but this time we have more reliable information that allows us to clarify some things.
As in previous rumors it speaks of three versions of the AMD Radeon RX Vega and they maintain even the nomenclatures XTX, XT and XL that already knew. However, there is an important novelty, and is that contrary to what said previous rumors the first two versions will have no differences at the hardware level.
This means that the base of the same will be the full Vega 10 graphics core and therefore both will have 4,096 shaders, 256 texture units, 64 raster units, a 2.048-bit bus and 8 GB of HBM2.
What differentiates them then? As the cooling system and the TDP. In the case of the XTX version we would find a liquid cooling kit type AIO (all in one) identical to the one we saw in the Radeon Vega Frontier Edition, while in the XT version will use an air cooling system.
The TDP of the former will also be higher than that of the second (375W vs 285W), suggesting that the working frequencies of the XTX version would be greater than those of the XT version. This should translate into higher performance, but we still do not know how to scale Vega exactly with each additional MHz so it is impossible to specify anything at the moment.
Finally the XL version will also use the Vega 10 core, although with a lower counting of shaders and texture units. In principle, its specifications should fall to 3,584 shaders and 224 textured units, although it would maintain the 64 raster units, the 2.048-bit bus and the 8 GB of HBM2.
Everything indicates that there will be no version with 16 GB of HBM2, although we cannot rule out that AMD decides to release a version with that amount of memory later. If everything goes according to plan the AMD Radeon RX Vega will be officially announced on July 30th.
