fp16TFLOPS (74.6, dense) is AMD's directly published "Peak Half Precision (FP16 Matrix) Performance" figure — no structured-sparsity variant listed for this card (RDNA3 doesn't get the 2:4-sparsity feature that RDNA4 parts do). fp8TFLOPS omitted — RDNA 3 has no native FP8 matrix support; AMD's page instead lists INT8/INT4 matrix rates (captured as int8TOPS/int4TOPS) via "AI Accelerators" (120, used as matrixCoreCount) rather than dedicated FP8 hardware. memoryBandwidthGBs uses the raw GDDR6 figure (624 GB/s); AMD's page also lists an "Effective Memory Bandwidth" of 2,708 GB/s (Infinity Cache-inflated), not used here to stay consistent with how every other entry in this collection reports raw, not cache-effective, bandwidth. No Launch Date field is published on this page; launchDate (2023-09-06) was added 2026-09-20 from AMD's own Gamescom press release of 2023-08-25, which states availability beginning September 6, 2023 for both this card and the RX 7700 XT (amd.com/en/newsroom/press-releases/2023-8-25-new-amd-radeon-rx-7800-xt-and-radeon-rx-7700-xt-gr.html).
