Compatible ROCm versions
none — no ROCm release has ever listed gfx1032 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.
Included as an unsupported card, same as the RX 6600 it shares a die with. Navi 23 = gfx1032, which appears in no ROCm release's supported-target list. Added 2026-09-21 alongside the RX 6750 XT to complete the two unsupported RDNA 2 target families, so someone searching a specific SKU finds a page rather than a gap.
The community route is HSA_OVERRIDE_GFX_VERSION=10.3.0, borrowing gfx1030's ABI from the same RDNA 2 family — unofficial, self-managed, and not reflected in this site's compatibility data. Note that 8 GB of VRAM binds before ROCm status does for local LLM work; run anything you plan to load through /vram-calculator/ first.
A refresh of the RX 6600 XT rather than a new design: same 32 CUs, 2048 stream processors, 11.1 B transistors and 32 MB Infinity Cache, with faster 17.5 Gbps memory (280 GB/s) and a 180 W board power.
fp16TFLOPS and fp8TFLOPS intentionally omitted — RDNA 2 has no matrix/AI-accelerator cores; AMD's page lists only "Peak Half Precision (FP16 Vector) Performance: 21.59 TFLOPs" (packed-math vector rate, captured as fp16TFLOPSVector) with no "AI Accelerators" count, so matrixCoreCount is omitted too.
peakClockMHz uses the published Boost Frequency ("Up to 2635 MHz"), not the 2410 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-6650-xt.html ("Expand All" spec accordion), pulled 2026-09-21.
