Highlighted rows are where these differ.

Ascend 950DT

  • 4 TB/s memory bandwidth and a 2 TB/s interconnect, 2.5x the Ascend 910C
  • HiZQ 2.0 is Huawei's own memory standard rather than a licensed HBM3 or HBM3e part
  • Indicated price rose 20% to 50% in two months to September 2026, on a memory shortage

Best for serving models where Nvidia cannot be bought.
