In real life it would be subsampled 4:2:0 and 1000hz is nonsense because it's not divisible by 24 or 30. So a more reasonable 8k@960hz 4:2:0 is (76804320960) * (8 + 2 + 2) = ~356Gb/s or only 35.6Gb/s if you pick a reasonable 96Hz.

By 960Hz even a lossless delta coding scheme on the wire could reduce the bandwidth by over 10X for any normal footage.

But then if you add some kind of encoding to reduce the bandwidth you sacrifice the monitor response time that a gamer who wants to run doom @ 1000fps would demand, because decoding takes some time.
