AMD Radeon PRO W7900 Dual Slot 48GB
Overview
The Radeon PRO W7900 Dual Slot is the same 96 compute unit, 48 GB ECC card as the original W7900, rebuilt into a double-slot cooler so that four of them fit in one workstation. That is the entire point of the product: 192 GB of GDDR6 and 492 TFLOPS of aggregate FP16 matrix in a machine you can put under a desk. Per card the numbers are unchanged at 61.3 TFLOPS of FP32 vector, 123 TFLOPS of FP16 matrix, 864 GB/s of bandwidth and 295 W of board power. AMD announced it at Computex 2024, a year after the triple-slot original.

Every figure here is dense. The vendor documents no structured (2:4) sparsity mode for this part, so there is no second number to quote.
Per watt divides the dense figure by the 295 W board power. Where only a sparse figure exists, the cell says so.
