New developer documentation from AMD suggests the company is working on a new single-die Opteron server chip that features 8 modules, working out to a total of 16 cores on a single piece of silicon. This would be AMD's first chip of this kind, as Opteron 6300 "Abu Dhabi" series 16 core chips consist of two 8-core dies.
What's more, unlike the current "Abu Dhabi" and "Seoul" chips, the new silicon features a full-fledged uncore, complete with a PCI-Express gen 3.0 root complex that's integrated into the processor die. In what's more proof that it's a single die with 8 modules and not an MCM of two dies with 4 modules each, the document describes the die as featuring four HyperTransport links; letting it pair with four other processors in 4P multi-socket configurations. Such systems would feature a total core count of 64. There's no clarity on which exact micro-architecture the CPU modules are based on.
