Common questions
Cambricon MLU370-X8 vs Cerebras WSE-3 (Wafer-Scale Engine 3): which is faster for training?
Cerebras WSE-3 (Wafer-Scale Engine 3) has 651.04x the dense FP16/BF16 throughput of the other (Cambricon MLU370-X8: 96 TFLOPS; Cerebras WSE-3 (Wafer-Scale Engine 3): 62,500 TFLOPS). Real-world training speed also depends on memory bandwidth, interconnect, and software stack: see the spec diff for those inputs.
Cambricon MLU370-X8 vs Cerebras WSE-3 (Wafer-Scale Engine 3): which has more memory?
Cambricon MLU370-X8 carries more HBM (Cambricon MLU370-X8: 48 GB LPDDR5; Cerebras WSE-3 (Wafer-Scale Engine 3): 44 GB on-die SRAM). Memory capacity sets the largest model that fits on one chip without partitioning; memory bandwidth sets inference throughput.
Cambricon MLU370-X8 vs Cerebras WSE-3 (Wafer-Scale Engine 3): which is more power-efficient?
Dense FP16/BF16 TFLOPS per watt: Cambricon MLU370-X8 0.38 (96 ÷ 250 W); Cerebras WSE-3 (Wafer-Scale Engine 3) 2.72 (62,500 ÷ 23000 W). Cerebras WSE-3 (Wafer-Scale Engine 3) wins at the die level; system-level efficiency also depends on cooling and interconnect.
