Radeon VII

Added 2026-09-21 after an r/ROCm commenter asked "no gfx906?" — the collection had the Instinct MI50 (also gfx906) but not the consumer Vega 20 card, which is the one people actually encounter second-hand. The most important fact about this card is that its support was REMOVED. gfx906 was supported from ROCm 4.5.0 through 6.0.2 (2024-01-31) and dropped in 6.1.0 (2024-04-16). It is the only ROCm gfx target in this collection that ever lost support — every other gfx target either gained it and kept it, or never had it. That is a statement about ROCm targets specifically, NOT about this collection as a whole: NVIDIA has retired Kepler, Maxwell, Pascal and Volta, which current CUDA (compute capability 7.5 and up) no longer lists, covering more cards here than the AMD side does. See /rocm-consumer-gpus/ for the derived comparison. So this card reads as "supported" in any guide, blog post or Stack Overflow answer written before April 2024, and is a dead end on every currently-supported ROCm release. See /rocm-consumer-gpus/ for the options. Why that matters more than it sounds: 16 GB of HBM2 at 1024 GB/s is still more memory bandwidth than any consumer Radeon released since, including the RX 7900 XTX (960 GB/s), on a card that now sells cheaply second-hand. On paper it looks like the bargain of the local-LLM world. The bandwidth is real; the software support is gone. fp16TFLOPS and fp8TFLOPS intentionally omitted — Vega has no matrix/AI-accelerator cores (AMD's spec record publishes no "AI Accelerators" count for this card, unlike RDNA 3/4 parts), so the 27.7 TFLOPs figure is the packed-math FP16 vector rate, captured as fp16TFLOPSVector. matrixCoreCount omitted for the same reason. fp64TFLOPS is deliberately NOT recorded. This card is well known for an unusually generous 1:4 FP64 rate for a consumer part, but AMD's own spec record publishes no double-precision figure for it, so nothing is entered here rather than deriving it from the FP32 number. cacheMB omitted — Vega predates AMD Infinity Cache entirely, so there is no comparable figure (not a data gap). peakClockMHz uses the published Boost Frequency (1750 MHz); base is 1400 MHz. AMD's product page for this card is gone (every URL pattern tried returns 404), so the data comes from AMD's own live specifications comparison tool at amd.com/en/products/specifications/graphics.html, which still carries a structured spec record for it in an embedded JSON data model — the same sourcing route used for the MI6/MI8 entries. That record publishes Launch Date as the bare year "2019" with no month or day, so launchDate is omitted and only releaseYear is set. No MSRP, no PCIe bus type and no ECC line are published there either. Source: amd.com/en/products/specifications/graphics.html (embedded product record "AMDRadeonVII"), pulled 2026-09-21.
