Three cores is simply 3 cores, the core is also called the kernel, is the CPU most important component.
The three nuclear products were first developed by AMD.
When AMD suddenly announced that it would launch its primary tri-core processor phenom Tripe-core in the first quarter of 2008, the entire industry felt somewhat unprepared, after all, the focus was on 1-2-4-8-16, a double core growth model. With Intel's aggressive push on the hard way for several quarters, AMD urgently needs to inject fresh blood, and when the K10 outlook is unclear, the three core of the sword Walk slant is likely to achieve unexpected results.
As for why three core processors are introduced, AMD's claim is that customers need richer, more unique desktop processor products, and that customer needs drive more processor cores to extend the user experience.
Technically, the three-core processor is the product of AMD's fall again in the frequency war. AMD internal engineers point out that when testing within FAB, the frequency of cores in the quad core processors can be mismatched at some point, such as three cores running at 2.6GHz, and the fourth can only reach 2.0GHz. At this time, AMD has two options: one is to demote three core to 2.0GHz, to make the finished product, the second is to block out the physical deficiency of the 2.0GHz core, thus getting 2.6GHz of the three core processors. Obviously, the latter will doubtless be wiser, so that it can get a higher frequency of products, and because AMD is using a direct-attached structure, this can be said to be the original three core products.
