AMD's upcoming Radeon RX Vega is so close I can almost smell the PCB, and now we have news of 3 versions of Radeon RX Vega that gamers will have to choose from, something that we've heard previously. The names being used from 3DCenter are: Vega XTX, Vega XT, and Vega XL.
- Vega XTX: water-cooled Radeon RX Vega (375W TDP)
- Vega XT: air-cooled Radeon RX Vega (285W TDP)
- Vega XL: cut-down Radeon RX Vega (285W TDP)
The cut-down Radeon RX Vega XL product reportedly has 3584 stream processors and a 285W TDP, with what I'm sure will be 8GB of HBM2, and I'm going out on a limb by saying this will be the GTX 1070 competitor. I'm hoping that AMD will release a Radeon RX Vega Nano, similar to the Radeon R9 Nano, but my sources said earlier this year "there will be no Nano-like RX Vega card". Boo.
There's no 16GB HBM2 model listed here, but I would say AMD will save the HBM2 chips for a dual-GPU card with 8GB HBM2 per GPU, for 16GB HBM2 total and 2 x Vega XT GPUs. This would be a monster, but I don't think AMD has the Vega or HBM2 yields to pull this off. I think we'll see Vega 20 with a dual-GPU offering later this year, or early 2018... before we start to float towards Navi.
