M4 Max 64GB vs AMD Radeon Pro W7800 48GB for local LLMs
4 reports on the M4 Max 64GB and 1 on the AMD Radeon Pro W7800 48GB
Which is faster for local LLMs?
On Qwen3.8 125B · 6B active at 3-bit, the M4 Max 64GB runs at 52.6 tokens per second (one run) and the AMD Radeon Pro W7800 48GB at 90.0 (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 1.6x higher on the AMD Radeon Pro W7800 48GB (546 GB/s on the M4 Max 64GB, 864 on the AMD Radeon Pro W7800 48GB).

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.
