Intel Core 2 Duo (Merom)

Intel Core 2 Duo The Intel 2 Core is the successor of the Intel Core Duo (Yonah) processor. Even if the name seems like a second version, the Core 2 Duo is "only" a mobile version of the desktop processor with the same name and not designed for mobile applications in the first place like its predecessor. The architecture is changed in many ways, which introduced EM64T, SSSE3 and improved the performance by up to 25 percent. The 667 MHz FSB versions are part of the "Napa"- and the 800MHz FSB versions of the "Santa Rosa"-platform. It is part of the hardware from both the Centrino Duo and Centrino Pro brands. Features Dual Core EM64T Intel Virtualization Technology XD-Bit MMX, SSE, SSE2, SSE3, SSSE3 instruction sets 667 or 800 MHz FSB 65 nm fabrication process 4 MB or 2 MB L2-Cache with dynamic cache sizing Enhanced Intel SpeedStep (EIST), power states: normal (C0), AutoHALT/MWAIT (C1), Stop Grant (C2), Deep Sleep (C3), Deeper Sleep (C4)
