Huawei Atlas 200I A2 20 TOPS vs Huawei Atlas 300I Duo 48GB

The Atlas 200I A2 is the newer part: Da Vinci, launched in 2023, against the Atlas 300I Duo's Da Vinci from 2022. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Dense throughput for the Atlas 200I A2 against the Atlas 300I Duo: FP16 10 vs 140 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 12 GB against 48 GB, fed at 51 GB/s versus 408 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.
