AMD Radeon RX 6650 XT
Refreshed 6600 XT with slightly faster GDDR6 (280 GB/s). 8 GB VRAM ceiling unchanged. ~40-55 tok/s on 7B Q4 with ROCm. Same buyer-decision shape as the 6600 XT — VRAM is the limiter, the bandwidth bump doesn't change which models fit.

Sub-scores sum to 303 / 1000. Headline = 303 × 0.70 (Estimated-confidence discount) = 212. This is an algorithmic performance-tier score — distinct from, and often lower than, the editorial “Our verdict” below, which weighs value and real-world fit (especially for hardware we haven’t measured yet).

Extrapolated from 280 GB/s bandwidth — 28.0 tok/s estimated. No measured benchmarks yet.

The RX 6650 XT is for operators who need a cheap ROCm runner for 7B and smaller models, and who already know 8 GB VRAM is the hard ceiling. It runs 7B Q4 at 40-55 tok/s and 13B Q4 at 20-28 tok/s with aggressive quantization, but any model exceeding 8 GB is off the table. The 280 GB/s bandwidth is a minor bump over the 6600 XT, so the token rate improvement is marginal. What breaks: 30B+ models, 13B at high precision, and any workload that needs more than 8 GB. Software stack is limited to ROCm; no CUDA or TensorRT support. Pass if you need to run 13B comfortably or plan to scale up—an 8 GB card is a dead end for local AI growth. At $230 used, it's a fair entry point for ROCm experimentation, but the VRAM ceiling makes it a short-term tool, not a long-term investment.
›Why this rating
The RX 6650 XT earns a 5.5 for its low price and decent 7B performance, but the 8 GB VRAM cap and limited ROCm ecosystem drag the score down. It's a passable starter card, not a serious local AI workhorse.
