Compatible ROCm versions
Shares the Navi 21 die (and therefore gfx1030) with the RX 6800 XT / 6900 XT / 6950 XT, so ROCm's gfx1030 support covers this card too even though AMD's compatibility matrix never names it — the same reason gpuNames.ts describes itself as flagship names only, not an exhaustive SKU list.
fp16TFLOPS and fp8TFLOPS intentionally omitted, not merely unconfirmed: RDNA 2 has no dedicated matrix/AI-accelerator cores (introduced in RDNA 3), so there is no matrix-throughput figure comparable to the rest of this collection. AMD's page confirms by omission — it lists only "Peak Half Precision (FP16 Vector) Performance: 32.33 TFLOPs" (packed-math vector rate, 2x FP32, captured as fp16TFLOPSVector) with no "FP16 Matrix" row, and no "AI Accelerators" count, so matrixCoreCount is omitted as well. Same treatment as the RX 6900 XT entry.
peakClockMHz uses the published Boost Frequency ("Up to 2105 MHz"), not the 1815 MHz Game Frequency. No PCIe "Bus Type" line is published on 6000-series pages (unlike 9000-series), so pcieGen is left unset rather than assumed. AMD publishes no MSRP on this page, so msrpUSD is omitted.
