Compatible ROCm versions
Same Navi 21 die (gfx1030) as the RX 6800 / 6900 XT / 6950 XT, so it inherits ROCm's gfx1030 support without being named in AMD's compatibility matrix.
fp16TFLOPS and fp8TFLOPS intentionally omitted — RDNA 2 has no matrix/AI-accelerator cores, so there is no matrix figure comparable to the rest of this collection; AMD's page lists only "Peak Half Precision (FP16 Vector) Performance: 41.47 TFLOPs" (captured as fp16TFLOPSVector) and publishes no "AI Accelerators" count, so matrixCoreCount is omitted too. Same treatment as the RX 6900 XT entry.
peakClockMHz uses the published Boost Frequency ("Up to 2250 MHz"), not the 2015 MHz Game Frequency. No PCIe "Bus Type" line is published on 6000-series pages, so pcieGen is left unset. AMD publishes no MSRP on this page, so msrpUSD is omitted. Source: amd.com/en/products/graphics/desktops/radeon/6000-series/amd-radeon-rx-6800-xt.html ("Expand All" spec accordion), pulled 2026-09-20.
