AMD Radeon PRO W7800 48GB
Overview
The 48 GB Radeon PRO W7800 takes the 70 compute unit W7800 bin and gives it the W7900's memory system: 48 GB of ECC GDDR6 on a 384-bit bus at 864 GB/s, with 96 MB of Infinity Cache. Compute is unchanged from the 32 GB card at 45.2 TFLOPS of FP32 vector and 90.4 TFLOPS of FP16 matrix, and so is the 260 W board power, so the whole value of the SKU is capacity and bandwidth for models that will not fit in 32 GB. It stays a double-slot card, which makes multi-GPU builds practical. RDNA 3 offers no FP8 and no structured sparsity, and AMD publishes no FP64 or BF16 rate.

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 260 W board power. Where only a sparse figure exists, the cell says so.
