that’s surprising to.. almost no one? 1TBPS is nothing to scoff at
- blibble 2y agoin terms of IPC, DDR5 can do about 50GB/s per memory channel assuming you're only shuffling bytes around, on bare metal this would be ~20 DDR5 channels worth or 2 servers (12 channels/server for EPYC) you can get an awful lot of compute these days for not very much money (shipping your code to the compressed video instead of the exact opposite would probably make more sense though)

- blibble 2y agomultiply 50 gigabytes * 20 and tell me what you get pro-tip: it's quite a bit bigger than a terabit
- CyberDildonics 2y agoTerabits vs gigabytes What does this mean? The article says 'TB' which would be terabytes. Terabytes are made out of gigabytes. There is nothing faster than straight memory bandwidth. DDR5 has 64 GB/s max. 12 channels of that is 768 GB/s. Terabytes per second is going to take multiple computers, but it will be a lot less computers if you're using shared memory bandwidth and not some sort of networking loopback.
