The AMD Polaris 10 GPU has a maximum TDP of 175W but cards will actually consume much less than that. The GPU was initially built to support HBM memory but AMD chose to go the GDDR5/X route since it offers a better value currently. We will get to see HBM on AMD GPUs when Vega launches but until then, only Fury series will have HBM support. The Polaris 10 GPU is said to have 3DMark Firestrike Ultra performance around 4000 points which is about what a Radeon R9 Fury X and GeForce GTX 980 Ti score. By 4000 points, we don’t mean exactly 4000 but it’s actually quite a bit less but that’s the number we were told.
