AMD EPYC Rome, the world's first Real-Time 8K HEVC Coding
By Adan Flannigan 2019-09-16 528 0
High Efficiency Video Encoding (HEVC), also known as H.265, is a video compression standard designed as an advanced version of the widely used AVC (H.264). Compared to AVC, HEVC offers 25 to 50% better data compression at the same video quality, or greatly improved video quality at the same bit rate. This process requires powerful processors.
A 64-core EPYC 7742 with 7 nm Zen 2 microarchitecture encoded 8K footage in real time at 79 frames per second with the 10-bit color required for HDR. The EPYC 7742 is the first 64-core x86 processor in the world to enter a standard general-purpose socket, and the Beamr coding software is designed to use 64 of these cores. The fact that the EPYC 7742 processor does this alone is a very good development for the progressing process, while the multiple execution of a process is a major concern for CPUs with ever increasing number of cores, from consumer to server.
We can see 8K live broadcast at 2020 Tokyo Olympics
The demand for 8K images to encode in real time at a good quality level has increased with the increase in the sales figures of the 8K displays in the market. For the time being, the 8K displays, which are still not so common, will be much more involved in our lives in the future. We can see 8K live stream in the near future. Especially in the 2020 Tokyo Olympics, it is being talked about using 7742's coding and streaming capabilities to make 8K live streaming.
AMD says EPYC can do more than just stream television. The chips are also suitable for streaming cloud gaming content as a way to play games with services like GeForce Now and Google Stadia. However, AMD said that the previous generation of Naples-based EPYC processors is sufficient for these applications, but 8K performance is very low.
