Intel Arc B580 12GB vs Intel Arc Pro B60 24GB

The Arc Pro B60 is the newer part: Battlemage, launched in 2025, against the Arc B580's Battlemage from 2024. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Memory is 12 GB against 24 GB, fed at 456 GB/s versus 456 GB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.

For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
