AMD has officially confirmed that its high-end Vega GPU is due early next year, and even unveiled some specs, including 8GB of HBM2 memory, 512GB/s of bandwidth, 12.5TFLOPS of floating-point performance.
If AMD is eager to make a breakthrough in the high-end space against NVIDIA, then it has to plan something more. The latest post at Fudzilla indicates that Vega is coming available in different variants, one with HBM 2, one with GDDR5, and maybe more. AMD’s previous GPU architecture Fiji was coming in Fury X, Fury and R9 Nano, so it would not surprise us if Vega were introduced to multiple cards.
Let’s make a bold assumption here: the full version of Vega is going to pack HBM 2 to challenge the GeForce GTX 1080, and would be priced above CNY4000. And the cut-down version will have some stream processor units blocked and use cheaper GDDR5 or GDDR5X memory.
Will there be a third outcome utilizing 8Gbps of GDDR5 memory? Anything could happen.
