Transmitting data at gigabit speed to another Processor?
Ethernet is really inefficient, and the delays (OMFG) and basing processing offloading on a gigabit ethernet port that, if lucky, might get upto 400Mb/s on a good day depending on the network chip and interface selected, is not really conducive to a real-time co-processor.
Gigabit ethernet isn't really gigabit, and gigabit is not as fast as everyone thinks .. it's just that common internet speeds of 4-30Mbps is pitifully slow
The sata port is configured to get 1.5Gbps consistently and will get a reliable 100MB/s (800Mb/s).
The way I see it, they can have both USB ports 2x480Mb/s (480Mb/s reliably), the sata port 1500Mb/s (1000Mbps reliably) & ethernet port 1000Gb/s (400Mb/s reliably) givin a total of 1880Mb/s and still end up without enough processing power for new games, because the CELL cpu is busy co-ordinating communications with the new coprocessor through the various ports ...
It will be interesting to see, regardless.
