Hardware comparison
MacBook Pro / Mac Studio M5 Max (36GB) vs NVIDIA RTX 3090 (24GB) for local LLMs
How the two stack up for running open-source LLMs locally — memory, bandwidth, price, and how many of the 69 tracked models each one can run.

These prices cover different purchases: a GPU card excludes its required host PC; a complete system includes the machine. No price winner is marked. Prices are approximate catalog estimates; check current configurations and prices before buying.
The recommended quants differ. These estimated speeds are not a like-for-like comparison. Estimates use 4,096 context tokens, llama.cpp and one stream.
Both run the same number of models, but the MacBook Pro / Mac Studio M5 Max (36GB) has more memory (36.0 GB), so it can hold larger models at higher quality. The NVIDIA RTX 3090 (24GB) has more memory bandwidth (936 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
