We take a deep dive into the new Intel Xe 2 architecture on page 78, but we’re having a look at the first running silicon here. On paper, the B580 looks decidedly less powerful than the older A750, never mind the full-fat A770 16GB card. The B580 ‘only’ has 20 Xe-cores, compared to 28 on the A750 and 32 on the A770. The re-architecturing of the Xe cores from SIMD32 to SIMD16 means that the B580 should behave roughly on the level of a 34-Xe-core Alchemist chip. Except we need to factor in higher clock speeds as well, so this works out at around 28% more performance in the real world, give or take.
