There are two approaches. On the first one, called “multi-chip”, each core is made by different chips that are put together in a single package. Pentium D is a good example of a dual-core CPU that uses this approach. On CPUs based on this technology when one of the CPU cores wants to talk with the other, it needs to go
outside the CPU package, i.e. use the front side bus.
Intel® multi-core technology provides new levels of energy efficient performance, enabled by advanced parallel processing and hafnium-based 45nm technology. Central to our technology roadmap, Intel® multi-core processors based on 45nm are paving the way to the next revolution in processor technology 32nm multi-core processors. In this set-up cores 1 and 2 would share a memory cache, as would cores 3 and 4. If core 1 or 2 needs to communicate with 3 or 4, it is an external communication, usually via the frontside bus.
Intel® Core™2 Extreme Quad-Core Processor—World’s First Quad-Core for the desktop. This quad-core desktop processor will be the ultimate gaming machine and multimedia processing engine for today’s growing list of threaded applications. In addition to being excellent for intensive multitasking, the Intel Core 2 Extreme quad-core processor will provide impressive gaming performance, offering plenty of headroom for tomorrow’s thread-intensivegames. Gamers can expect a smoother, more exciting gaming experience through
the distribution of artificial intelligence (AI), physics and rendering across four hardware threads. Ideal for processor-intensive, highly threaded applications, the Intel Core 2 Extreme quad-core processor will be the top choice for multimedia enthusiasts, gamers, and workers in demanding multitasking environments. It will feature 2.66 GHz core speed and 1066 MHz front side bus speed.
