RX 9060 XT 8GB runs Qwen 3 8B — but there's less headroom than you'd think

Sized at Q4_K_M with a 8K context: weights, KV cache and framework overhead, against what RX 9060 XT 8GB leaves free. Qwen 3 8B at Q4_K_M needs 7 GB and you have 8 GB available, so it fits with 1 GB to spare. Expect 21–43.6 tok/s (estimated).

Questions people ask about this pairing

Can an RX 9060 XT 8GB run Qwen 3 8B?

Yes. Qwen 3 8B at Q4_K_M needs 7 GB and you have 8 GB available, so it fits with 1 GB to spare.

How fast will Qwen 3 8B actually run?

Around 21–43.6 tok/s (estimated) on this setup at Q4_K_M. Decode speed on a local model is set by memory bandwidth rather than compute, so the figure moves with the card's bandwidth and the bytes read per token — not with its price.

Does a longer context change what Qwen 3 8B needs here?

Yes, and it is the figure people forget. The 7 GB above already includes the KV cache at 8K; that cache grows roughly linearly with context, so doubling the window adds real gigabytes rather than a rounding error. If you plan to work with long documents on RX 9060 XT 8GB, size for the context you will actually use, not the default.
