Yonah (microprocessor)

Yonah is the code name of Intel's first generation 65 nm process CPU cores, based on cores of the earlier Banias (130 nm) / Dothan (90 nm)Pentium M microarchitecture. Yonah CPU cores were used within Intel's Core Solo and Core Duo mobile microprocessor products. SIMD performance on Yonah improved through the addition of SSE3 instructions and improvements to SSE and SSE2 implementations; integer performance decreased slightly due to higher latency cache. Additionally, Yonah included support for the NX bit.
