What actually differs
The Atlas 300I Duo is the newer part: Da Vinci, launched in 2022, against the Ascend 310's Da Vinci from 2018. 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 Ascend 310 against the Atlas 300I Duo: FP16 8 vs 140 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
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.
