Looking back at the roadmap that we published back in May of last year, AMD's many-core riposte was to come in the form of the six-core Istanbul Opteron, ostensibly based on Shanghai, to be released in H2 2009. It'll ship with the same 6MB L3 cache, registered DDR2 memory support, and HyperTransport 3, as well as the usual virtualisation goodies.
AMD's been showcasing the six-core Istanbul at its Austin, Texas campus, and the folks over at The Tech Report got the skinny. Here's a picture they grabbed of a quad-socket box with, well, four Istanbul CPUs inside.

24 cores purring along, producing a Stream memory-bandwidth score of around 42GB/s, it is claimed.
AMD keeps the Socket-F platform alive and users of present Opteron boards should be able to transition over to Istanbul with a BIOS update on the majority of boards.
At least this chip hasn't done a disappearing act from the roadmap, as the eight-core 'Montreal' did a while back.
Question is, will AMD bring the technology down from server to the desktop in the form of a Phenom FX?
