News of November 3, today,Cambrian officially released the third-generation cloud AI chip Siyuan 370.According to reports, Siyuan 370 is built on the 7nm process and is also the first AI chip using chiplet technology in the Cambrian. Siyuan 370 integrates 39 billion transistors,The maximum computing power is as high as 256TOPS (INT8), which is twice the computing power of the second-generation Cambrian Siyuan 270.
The official said that with the Cambrian’s latest smart chip architecture MLUarch03, compared to the increase in peak computing power, the measured performance of Siyuan 370 is better.
Take ResNet-50 as an example,The measured performance of MLU370-S4 accelerator card (half-height, half-length) is twice that of mainstream GPUs of the same size.
The measured performance of the MLU370-X4 accelerator card (full-height, full-length) is comparable to mainstream GPUs of the same size, and its energy efficiency is significantly ahead.
It is worth mentioning that,Siyuan 370 is also the first cloud AI chip in China that supports LPDDR5 memory. The memory bandwidth is 3 times that of the previous generation.The energy efficiency of memory access is 1.5 times that of GDDR6.
In terms of decoding, Siyuan 370 supports 132 channels of 1080p video decoding or 10 channels of 8K video decoding.
In terms of encoding, the new encoder, through flexible rate optimization (RDO) control, multiple reference frames, secondary encoding and other features, saves 42% bandwidth compared to the previous generation product under the same image quality (full HD video PSNR). Effectively reduce bandwidth costs.
