M3 Ultra 512GB vs NVIDIA RTX 5060 Ti 16GB for local LLMs
41 reports on the M3 Ultra 512GB and 72 on the NVIDIA RTX 5060 Ti 16GB
Which is faster for local LLMs?
On Gemma 4 26B · 4B active at 4-bit, the M3 Ultra 512GB has 87.8 generation tokens/s (one run); prompt processing 2595.3 tokens/s (one run); the NVIDIA RTX 5060 Ti 16GB has 95.2 generation tokens/s (one run); prompt processing 3476.0 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 1.8x higher on the M3 Ultra 512GB (819 GB/s on the M3 Ultra 512GB, 448 on the NVIDIA RTX 5060 Ti 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.
