Yonah
Yonah was the code name for Intel's first generation of 65 nm process mobile microprocessors, based on the Banias/Dothan Pentium M microarchitecture, incorporating LaGrande security technology. SIMD performance has been improved through the addition of SSE3 instructions and improvements to SSE and SSE2 implementations, while integer performance decreased slightly due to higher latency cache. Additionally, Yonah includes support for the NX bit.
Intel Core Duo is the world's first low-power (less than 25 watts) Dual Core microprocessor, with the previous low being AMD's Opteron 260 and 860 HE at 55 watts. Core Duo was released on 5 January 2006, with the other components of the Napa platform. It was the first Intel processor to be used in Apple Macintosh products (although the Apple Developer Transition Kit machines, non-production units distributed to some developers, used Pentium 4 processors).[1]
Contrary to early reports, the Intel Core Duo supports Intel VT x86 virtualization technology, except in the T2300E model and proprietary T2050/T2150/T2250 mounted by OEMs (cf. the Intel Centrino Duo Mobile Technology Performance Brief and Intel's Processor Number Feature Table). The Intel Pentium Dual Core processors may or may not have this feature. However, it seems some vendors, like HP, have chosen to disable this feature,[2][3] with others making it available through a BIOS option.[citation needed]
Intel 64 (Intel's x86-64 implementation) is not supported by Yonah. However, Intel 64 support is integrated in Yonah's successor, the mobile version of Core 2, code-named Merom.
Believe me I tried it before researching annoyed me a little
