Intel Arc B580 vs NVIDIA Tesla P40

For running models locally, priced in Germany. At 128k context the first runs 4 models fully in memory, the second 9.

In short

The NVIDIA Tesla P40 has more memory for models: 24 GB against 12 GB. At 128k context the NVIDIA Tesla P40 runs 9 of the models we track fully in memory and the Intel Arc B580 4; only the NVIDIA Tesla P40 holds Gemma 4 26B-A4B. On the models both run fully in memory, the Intel Arc B580 is about 1.4× as fast as the NVIDIA Tesla P40 (estimated, median across models). In Germany the Intel Arc B580 costs 349 € at eBay and the NVIDIA Tesla P40 369 € at eBay (used): the Intel Arc B580 is 20 € cheaper.
