Hardware comparison
AMD RX 9070 XT (16GB) vs Intel Arc B580 (12GB) 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.

Both prices cover GPU cards only. A host PC is required and its cost is excluded. Prices are approximate catalog estimates; check current configurations and prices before buying.
The recommended models differ. These estimated speeds are not a like-for-like comparison. Estimates use 4,096 context tokens, llama.cpp and one stream.
The AMD RX 9070 XT (16GB) runs 18 more of the tracked models (48 vs 30), thanks to its 16.0 GB of memory. The AMD RX 9070 XT (16GB) has more memory bandwidth (645 GB/s). Higher bandwidth can help generation speed, but model, quant, architecture and runtime also affect the estimates.
