Intel Core Duo (Yonah)

The Intel Core is the successor of the Pentium M processor. The fabrication process was reduced again to 65 nm and with this generation Intel introduced Dual Core processors to the mobile market. The Intel Core processors feature a 667 MHz FSB and accompany the Napa Centrino platform. Features Dual Core 1.5 - 2.33 GHz clock speed 15 (low voltage) or 31 (normal voltage) watt thermal design power consumption 667 MHz FSB 151 Million Transistors 65 nm fabrication process 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) MMX, SSE, SSE2, SSE3 instruction sets, XD-Bit Intel Virtualization Extensions, except for T2300e

Thermal Specifications

The maximum temperature for safe operation is 100 °C.

GCC Optimization Flags

Safe, recommended optimizations for GCC 3.4.x and later:

-pipe -O2 -march=prescott -fomit-frame-pointer

Possibly unsafe optimizations for GCC 3.3.x and later:

-mfpmath=sse

Optimizations likely to break binary-only compatibility:

-ffast-math
