What actually differs
Both GPUs launched in 2026: the Ascend 950DT on Da Vinci v3 and the Atlas 350 on Da Vinci v3.
Dense throughput for the Ascend 950DT against the Atlas 350: FP16 547 vs 425 TFLOPS, FP8 1,034 vs 804 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 144 GB against 112 GB, fed at 4.0 TB/s versus 1.4 TB/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.
