In a document published by AMD some new information surfaced. It seems that AMD is working on a new 16-core processor, and that is a true 16 cores, thus not a an 12 CPU cores and 4 GPU cores combo or anything. And no it is not the existing AMD Opteron 6200 Series either. This is something new. Obviously such a processor would see a launch in the server segment first hence we think the processor will be an Opteron. The developer documents list the 16-core unit under Family 15h Models 30h – 3fh.
This 16-core processor will have a full uncore, which is terminology for the functions of a microprocessor that are not in the Core like QPI controllers, L3 cache, on-die memory controller and so on. The PCI Express and SPI are typically merged into the the chipset, not the Uncore.
There is no confirmed information available on what technology or family (Piledriver etc) the CPU cores are architectured but the Family 15h Models 30h – 3fh indicate SteamRoller CPU cores as previously released in AMD's Kaveri APUs; yet in this case with eight dual-core processor modules on a single die. Have a peek at the document right here.
