![]() ![]() Each element is 32 bits wide, making it a bit like AVX-2048.īecause the SIMD Engine has a 16-lane execution unit, the 64-wide wave is executed over four cycles. That means each instruction works across a 64-wide vector. Like GCN, Terascale 3 runs in wave64 mode. Terascale 3’s building blocks are called SIMD Engines, and the HD 6950 has 22 of them enabled out of 24 on the die. AMD’s Radeon HD 6950 uses the Terascale 3 architecture. The Radeon HD 6950 and Radeon RX 6900XT use very different architectures, even though both products belong to the 6000 series and share a brand name. Ideally I would compare the 6950 XT and 6900 XT, but that would cost money. I have an AMD Radeon HD 6950 to compare to the Radeon RX 6900 XT. Fortunately, we can figure this out in all the detail we’re used to. ![]()
