Notorious b.s.d. posted:"infinity fabric" is the new interconnect. like hypertransport, except, AMD. if anyone sees something about "infinity fabric" pls post it here its used in the current 8C chips- they're functionally 2 * 4C CCXs connected over that interconnect. thats what the graphs were showing, moving a thread between cores in the same CCX vs between the two CCXs thus hitting the fabric (although the graphs were trying to figure out which logical cores were the what i'm interested in is how the 2 socket systems are gonna handle big gpgpu clusters; each socket has 128 pcie lanes, but in 2 socket setups, 64 are used to provide the fabric interconnect so there's still 128 lanes leaving the sockets for the rest of the system, half from each socket
