Intel Core 2 Duo (Penryn)

The Intel 2 Core is the successor of the Intel Core 2 Duo (Merom) processor. Unlike the Merom, Penryn uses the new 45um process which makes it cooler and uses less power. Features Dual Core EM64T Intel Virtualization Technology XD-Bit MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, XD Bit, iAMT2, Intel VT instruction sets 800 or 1066 MHz FSB 45 nm fabrication process 3-6 MB L2-Cache Enhanced Intel SpeedStep (EIST)
