There have been rumors of the technical specifications of Vega 10 before, but VideoCardz are reporting again about the old slide from September and "what we know today".
This is great, as it can show how much the rumors nearly 6 months ago were pretty solid - so let's go over it again. Vega 10 will rock its 14nm GPU goodness, with 64 compute units (which are now called NCU). Vega 10 will consume up to 225W of power, and will be released in the first half of this year.
We should see two variants, one with 8GB of HBM2, and another higher-end card with 16GB of HBM2 - both offering 512GB/sec of memory bandwidth.
Dual Vega is where my excitement levels rise, with the same 14nm GPU - just two of them, and more HBM2 with higher bandwidth (1TB/sec). The dual-GPU graphics card will consume 300W of power, and will be released in the second half of 2017.
