AMD Radeon RX Vega 64 8GB
Overview
The Radeon RX Vega 64 was AMD's 2017 flagship and the first consumer card to pair HBM2 with a big GCN part: 64 compute units, 4,096 stream processors and 8 GB of HBM2 on a 2048-bit interface at 483.8 GB/s, inside a 295 W board. It is in this catalog as a tier-three historical reference rather than a recommendation, because 8 GB is too small for most modern local inference and 295 W buys only 12.7 TFLOPS of FP32. Its one architectural contribution that still matters is Rapid Packed Math, the feature that doubled FP16 throughput to 25.3 TFLOPS on the vector units; Vega has no matrix cores, so that packed rate is the ceiling and no BF16, FP8, INT8 or INT4 figure exists.

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.
