Tokyo Olympics 8K Broadcast Was Powered by Intel Xeon Platinum 8380H Servers
Intel has recently unveiled that their technology powered the 8K 60 FPS Tokyo Olympics broadcast which was available to select customers in Japan. The games were recorded in 8K at 60 FPS with 4:2:2 Chroma subsampling and 10-bit HDR which resulted in a bitrate of 48 Gbps. This uncompressed stream was then encoded on servers each featuring quad 28 core Xeon 8380H processors and 384 GB of ram into two HEVC distribution streams at 250 Mbps and 50-100 Mbps bitrates. These streams were then distributed to users over the internet where the 8K stream could be decoded and displayed on an 8K TV over HDMI 2.1. Intel used a workstation PC with an 18-core Xeon W-2295 and 64 GB of ram to decode and play the video stream on the TV. This 8K service was only made available to select NHK subscribers in Japan while most international broadcasts offered a maximum resolution of 4K.

2. "Reliable" is a relative term in these large scale installments since they run custom OS and custom software tuned specifically to its application.
I don't know why people are just making comments without reading the fine prints ( the software used in the pipeline mentioned in the slide ) and make a little research ( looking at the systems specs for that specific software ). Not every software is AMD EPYC CPU compatible, sorry.
They are using Spin Digital enc live V1.0 software and this software's platform support is;
OS Red Hat Linux 7/8, Ubuntu Linux 18.04/20.04
CPU X86_64. SIMD instructions: SSE 4.1, AVX2, AVX512, VNNI
SDI AJA Kona 5 (12G), AJA Corvid 44 (12G), AJA Corvid 88 (3G)

(Please don't tell team red I said that the supporters are rabbid)
I don't know if they paid anyone but you have to be pretty obtuse to not realize this is a publicity stunt for something that is otherwise impractical and irrelevant.
And this is a huge marketing point for Intel. Software usage has nothing to do with it. A GPU would have done the 8k encoding/decoding way more efficient and faster than any given CPU.
Besides, there is no mention the AVX512 Decoder/Encoder has been used.

This blade cuts both ways I hope you can see that. Intel's better marketing is AMD's lack of it. This is about spotting and capturing opportunities.
Stop the political comments.
