M1 16GB vs NVIDIA RTX 4070 for local LLMs
2 reports on the M1 16GB and 9 on the NVIDIA RTX 4070
Which is faster for local LLMs?
On Gemma 4 8B at 4-bit, the M1 16GB runs at 8.2 tokens per second (one run) and the NVIDIA RTX 4070 at 55.0 (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 7.4x higher on the NVIDIA RTX 4070 (68 GB/s on the M1 16GB, 504 on the NVIDIA RTX 4070).

Measured on both
Median tokens per second 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 quant level. Engines and context lengths can still differ between the runs. 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.
