MLU100 is a high-performance neural processor designed by Cambricon and introduced for the server market in mid-2018. The MLU100 is manufactured on TSMC's 16 nm process and operates at 1 GHz with a high-performance mode of 1.3 GHz.

Overview

In balanced mode which has a power envelope of 80 W, this processor has a theoretical peak performance of 128 trillion fixed-point (8-bit int) operations per second and 64 half-precision floating point (16-bit) TFLOPS. The efficiency of the chip slightly worsens at high-performance mode in favors of higher performances. In this mode the processor has a peak performance of 166.4 TOPS and 83.2 half-precision TFLOPS.
