Compatible ROCm versions
none — no ROCm release has ever listed gfx1031 as a supported GPU target (gfx). ROCm support is granted per target, so this card is not covered by any version, including the current one. The unofficial HSA_OVERRIDE_GFX_VERSION workaround is the usual route people take — see ROCm on consumer Radeon GPUs for what it does and where it breaks.
Deliberately included as an *unsupported* card. This is Navi 22 = gfx1031, which appears in no ROCm release's supported-target list — not in any 5.x, 6.x, 7.x or 10.x entry in this collection. That is not a data gap: ROCm grants support per gfx target, AMD has never validated gfx1031, and the 6700 XT / 6750 XT are among the most common cards people try to run ROCm on anyway, which is exactly why the HSA_OVERRIDE_GFX_VERSION workaround exists (typically HSA_OVERRIDE_GFX_VERSION=10.3.0, borrowing the gfx1030 ABI from the same RDNA 2 family). Unofficial and self-managed — see /rocm-consumer-gpus/ for the caveats.
fp16TFLOPS and fp8TFLOPS intentionally omitted — RDNA 2 has no matrix/AI-accelerator cores; AMD's page lists only "Peak Half Precision (FP16 Vector) Performance: 26.43 TFLOPs" (captured as fp16TFLOPSVector) with no "AI Accelerators" count, so matrixCoreCount is omitted too.
peakClockMHz uses the published Boost Frequency ("Up to 2581 MHz"), not the 2424 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-6700-xt.html ("Expand All" spec accordion), pulled 2026-09-20.
