BX80539KF20002M - Intel Xeon 2-Core 2.00GHz 667MHz FSB 2MB L2 Cache Socket PGA478 Processor

The Dual-Core Intel Xeon Processor LV is manufactured on Intel's advanced 90 nanometer process technology with copper interconnect. The processor maintains support for MMX Technology and Streaming SIMD instructions and full compatibility with IA32 software. The on die, 32 kB Level 1 instruction and data caches and the 2 MB Level 2 cache with Advanced Transfer Cache Architecture enable performance improvement over existing low power processors. The processor's Data Prefetch Logic speculatively fetches data to the L2 cache before an L1 cache request occurs, resulting in reduced bus cycle penalties and improved performance. The Dual-Core Intel Xeon Processor LV includes the Data Cache Unit Streamer, which enhances the performance of the L2 prefetcher by requesting L1 warm-ups earlier. In addition, Write Order Buffer depth is enhanced to help with write-back latency performance.
