Introduction
The Intel® CoreTM Duo processor and the Intel® CoreTM Solo processor are built on Intel’s next generation 65 nanometer process technology with copper interconnect. The Intel Core Solo processor refers to a single core processor and the Intel Core Duo processor refers to a dual core processor. This document provides specifications for all Intel Core Duo processor and Intel Core Solo processor in standard voltage (SV), low voltage (LV) and ultra low voltage (ULV) products.

The processor maintains support for MMX™ technology, Streaming SIMD instructions, and full compatibility with IA-32 software. The processor features on-die, 32-KB, Level 1 instruction and data caches and a 2-MB level 2 cache with Advanced Transfer Cache Architecture. The processor’s Data Prefetch Logic speculatively fetches data to the L2 cache before the L1 cache requests occurs, resulting in reduced bus cycle penalties. The processor includes the Data Cache Unit Streamer which enhances the performance of the L2 prefetcher by requesting L1 warm-ups earlier. In addition, the Writer Order Buffer depth is enhanced to help with the write-back latency performance.
