NVIDIA RTX 4060 Laptop 8GB vs AMD RX 9070 XT 16GB for local LLMs
3 reports on the NVIDIA RTX 4060 Laptop 8GB and 12 on the AMD RX 9070 XT 16GB
Which is faster for local LLMs?
On Qwen3.5 9B at 4-bit, the NVIDIA RTX 4060 Laptop 8GB has 37.7 generation tokens/s (one run); prompt processing 1828.8 tokens/s (one run); the AMD RX 9070 XT 16GB has 7.9 generation tokens/s (one run). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 2.5x higher on the AMD RX 9070 XT 16GB (256 GB/s on the NVIDIA RTX 4060 Laptop 8GB, 640 on the AMD RX 9070 XT 16GB).

Measured on both
Generation and prompt processing speeds from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same bit class. Each side shows the engines and reported context behind its median. Context can mean a configured window or prompt depth, so these are community comparisons with differing settings. How to read these

Estimated by the calculator
The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
