Intel Arc Pro A40 6GB vs Intel Arc A580 8GB

The Arc A580 is the newer part: Alchemist, launched in 2023, against the Arc Pro A40's Alchemist from 2022. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Memory is 6 GB against 8 GB, fed at 192 GB/s versus 512 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.
