Ascend 920: Specifications and Potential

The Ascend 920 is set to enter mass production in the second half of 2025. Built on SMIC's 6nm process, it boasts impressive specifications:

  • Up to 900 TFLOPs of BF16 compute
  • 4000GB/s of memory bandwidth
  • HBM3 memory module support
  • PCIe 5.0 and next-generation interconnect protocols

These features suggest that the Ascend 920 could be a viable alternative to Nvidia's restricted H20 chip for Chinese companies
