What Is a Quad Core Processor?

A quad-core processor is a processor based on a single semiconductor with four processor cores of the same function. In other words, integrate four physical processor cores into one core. Enterprise IT managers have also consistently sought ways to improve performance without increasing physical hardware coverage. Multi-core processor solutions address these needs, providing greater performance without increasing energy or physical space. [1]

The quad core is composed of two dual cores, and each dual core shares 4M L2.
In theory, when the two have not reached the full load, the results should be similar. When both sides reach full load at the same time, the performance of the quad-core should be double that of the dual-core.
The maximum increase in the physical quad-core over the physical dual-core is about 80%, and the maximum increase in the hyper-threaded quad-core over the physical dual-core is about 40%. The difference between the two is about double.

The three-core processor's cache advantage is more obvious. Although one core was lost, the shared L3 cache was not affected. It was originally shared by four cores and became three. Therefore, the L3 cache capacity accessible by each core can be increased by 8.33 when the system is fully loaded. %, Which helps improve the performance of cache-sensitive programs. In addition, the penetration rate of quad-core processors is still quite low (according to Mercury Research statistics, less than 2% of desktop processors shipped in the second quarter of 2007 are quad-core), and the optimization of multi-core applications is also seriously insufficient. And the triple-core architecture is no stranger. The Xbox 360 console is the triple-core IBM PowerPC.
