1. Overview
1.1 Introduction
Sophon SC1 is the latest deep learning accelerated card, an advanced fan-cooled module that
combines the BM1680 into a compact, easy to integrate package. It is designed for the inference of
multiple deep learning applications, allows users to calmly deal with the large-scale data.
There is one BM1680 on Sophon SC1, which contains 64 NPU, each NPU contains the following
configuration:
The single-precision peak performance of SC1 is 2TFlops/s, and SC1+ card which equipped with
two units of BM1680 reach the single-precision peak performance to 4TFlops/s.
Sophon SC1 card is equipped with 16GB of DDR4 memory, bandwidth up to 83.2GB/s. With the
provided SDK from Bitmain, you can further simplify the buffer management of DL workload to
achieve better load balancing.
Each Sophon SC1 card has a PCIE3.0x8 interface, can access large-capacity system DRAM
memory, to achieve bidirectional data exchange and streaming between the card and the system.
Sophon SC1 card max power consumption is 85W, Sophon SC1+ card max power consumption is
150W, the actual power consumption was dynamic according to the workload. For the convenience
of deployment, the card were carried out with active cooling design, to ensure that it can operate
stably in the range of 0
℃
~ 50
℃
ambient temperature.
