Intel Core 2 Duo / Quad / Extreme processor families
The latest generation of Intel x86-compatible processor, Core 2 Duo microprocessor family, was introduced on July 27, 2006. The Core 2 Duo processors include two cores, each core having 32 KB L1 data and 32 KB L1 code caches, and both cores having shared 2 or 4 MB L2 cache. The Core 2 Duo CPUs run at lower frequency than Pentium 4 processors, but they offer excellent performance due to more efficient architecture:
Core 2 Duo architecture includes other performance enhancing features. One of these features is a "macrofusion". This feature allows the processor to load and execute common instruction pairs as one instruction.
Overall, despite of lower processor frequency, the performance of Core 2 Duo family is much higher than the performance of Pentium 4. Lower processor speed of Core 2 Duo and Extreme processors also translates into lower power consumption. Core 2 Duo E6600 and E6700 processors have thermal design power 65 Watt (75 Watt for Core 2 Extreme x6800), while less efficient Pentium 4 Extreme Edition 3.73 GHz has thermal design power of 115 Watt.
