Figure. 1 MLU100-C Series Intelligent Processing Card appearance
Cambricon MLU100-C Series Intelligent Processing Card
The MLU100-C Series is the third generation of Intelligent Processing Cards provided by
Cambricon Technologies, on which populated one piece of Cambricon MLU100 chip. It can provide
extremely high calculating and video coding/decoding capacities to the Cloud Inference. Compared
with classical general-purpose CPU, MLU100-C can achieve a much bigger Performance/Powerconsumption ratio when handling the AI (Artificial Intelligence) related works, which makes it a real
AI-ready processor.
MLU100-C Series Intelligent Processing Card has a theoretical equivalent Peak Processing
Capacity of about 128TOPS(INT8), and it can be integrated into a server or workstation by a PCIe Gen3
x16 single slot. The Card’s heat dissipation solution is passive so the server (workstation) system should
be in charge of providing cooling airflow. The typical power consumption of the card is about 60-90W.
MLU100-C Series Intelligent Processing Card can support up to 16GB DDR4 with ECC capacity.
Cambricon MLU100-C Series Intelligent Processing Card’s key features:
1.
Versatility —— As a universal intelligent processor, it can support many kinds of Deep Learning
technologies and multimodal intelligent processing such as vision, voice and nature language, and
it can be used in a wide range.
2.
Sparsification —— By bringing sparsity technology into AI chip, it can achieve a theoretical peak
performance of 128TOPS (INT8).
3.
High efficiency —— Compared with GPU, it has featured special Instruction Set and processor
architecture dedicated to deep learning and AI, so it has much higher Performance/Powerconsumption ratio.
4.
Perfect software development environment —— Cambricon Technologies provides a thorough and
Cambricon, MLU100-C Series Intelligent Processing Card User Manual, 2018-09
mature development environment Cambricon NeuWare for MLU100-C series processors, and it has
included a full set of tools such as Application Development, Function Debugging and Performance
Optimizations.

Heat Dissipation Specifications
MLU100-C Series Intelligent Processing Card is using a passive heat dissipation method. The system
designers should pay attentions to below for the Airflow Volume at the entrance and Temperature
of Ambient relationship, so as to design a cooling system for the card and guarantee the card is
operating within the green recommendation area. The core clock frequency of the chip will be
decreased to half when the temperature of chip is over 87℃, and shut down when over 90℃.
