Intel Core i5

The Intel Core i5 (Arrandale) is the successor of the Intel Core 2 Duo (Penryn) processor. Unlike the Penryn, Arrendale uses the new 32um 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 1066 MHz Memory controller integrated 32 nm fabrication process 3 MB L2-Cache Enhanced Intel SpeedStep (EIST) Integrated GPU
