AMD Radeon RX 6600 8GB
Overview
The Radeon RX 6600 is the entry point of AMD's RDNA 2 desktop range, a 28 compute unit Navi 23 with 8 GB of GDDR6 at 224 GB/s and a 132 W board power that needs only a single eight-pin connector. It is the same die and the same core count as the workstation Radeon PRO W6600, which runs faster and adds professional certification. As with every RDNA 2 part, there are no matrix cores: 8.93 TFLOPS FP32 and a packed 17.86 TFLOPS FP16 at exactly twice that rate is the whole published ladder, with no BF16, FP8, INT8 or INT4 figure anywhere. At 8 GB it is a display card that can run small models, not an inference accelerator.

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