AMD Radeon 780M vs NVIDIA RTX 5070 Ti for local LLMs
6 reports on the AMD Radeon 780M and 45 on the NVIDIA RTX 5070 Ti
Which is faster for local LLMs?
On Gemma 4 26B · 4B active at 4-bit, the AMD Radeon 780M has 25.0 generation tokens/s (one run); prompt processing 208.7 tokens/s (one run); the NVIDIA RTX 5070 Ti has 137.7 generation tokens/s (one run); prompt processing 5951.0 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 7.5x higher on the NVIDIA RTX 5070 Ti (120 GB/s on the AMD Radeon 780M, 896 on the NVIDIA RTX 5070 Ti).

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.
