Intel Core i5

The Intel Core i5 (Arrandale) is the successor of the Intel Core 2 Duo (Penryn) processor. Unlike the Penryn, Arrandale uses the new 32um process (Nehalem microarchitecture) which makes it cooler and uses less power. Newer versions include Sandy Bridge microarchitecture (also 32um process) and Ivy Bridge microarchitecture (22 um process). 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 (22 nm for Ivy Bridge microarchitecture models) 3 MB L2-Cache Enhanced Intel SpeedStep (EIST) Integrated Intel HD Graphics AES NI
