On April 17, Tencent Cloud introduced that its self-developed video transcoding chip named Canghai had gained all eight prime scores in two classes on the newest MSU Video Codecs Comparison held by Moscow State University after months of rigorous testing.
In early 2019, Tencent launched the event of the Canghai chip. The agency performed in-depth analysis on {hardware} encoding and decoding algorithms, architectures, and engineering. By allocating totally different computing models, they have been in a position to stack numerous processing duties. It included devoted practical modules for Canghai chips to allow built-in video encoding acceleration, lowering redundant calculations and department judgments. This resulted in decrease energy consumption and price.
In March of final yr, Canghai chip efficiently handed assessments and is now in mass manufacturing with tens of hundreds of models deployed. It gives providers for Tencent‘s self-developed companies and public cloud prospects in eventualities similar to cloud gaming and reside streaming.

Canghai chips might be helpful for reside streaming platforms with lower than 200 viewers as they assist scale back computing prices. Additionally, in scenes with 4K and 8K extremely excessive definition and excessive body charge, Canghai chips present superior transcoding high quality and low latency in comparison with software program encoding.
The Yaochi graphics card of Canghai chip can adapt to numerous vendor GPUs, making it appropriate for cloud gaming. Additionally, the Canghai chip affords a high-density transcoding capability of 1024 channels per machine, which reduces the price of video transcoding.
Chips are probably the most important a part of the {hardware}. With the joint optimization of software program and {hardware}, Tencent Cloud has additionally gained sure product benefits in media processing (MPS). Now, Tencent Cloud’s providers supplied to prospects embody audio and video high quality enhancement, cloud-native recording, real-time particular results rendering, clever enhancing, and content material evaluation.
For eventualities with sturdy enterprise wants, Tencent has a long-term plan and funding in chip improvement and can mix computing energy eventualities to advertise the dimensions implementation of self-developed chips. Currently, Tencent has achieved end-to-end design and verification protection of chips.
Apart from the Canghai chip, Tencent Cloud additionally disclosed that its self-developed AI inference chip Zixiao has been put into use in inside operations and may present as much as 3 instances computing acceleration efficiency and over 45% total value financial savings.
