Joe, <the performance of the 460GX chipset is rated at 4.2 GB/sec, and 2.1 GB/sec in throughput implying for 4 Itanium procs. approx 500 MB/sec/Processor.> This is partially correct. The Itanium bus has a bandwidth of 2.1 GB/sec, and it is very similar to the Pentium III and Xeon buses. Saying that each processor in a 4-way system only gets 500 MB/sec is just as incorrect as saying that each processor in a 4-way P3 Xeon system only gets 200 MB/sec (from an 800 MB/sec bus). This is because it's uncommon for all four processors to utilize the bus at the exact same time. The 4.2 GB/sec number comes from the memory channel. It's achieved using lots of memory interleaving. The memory channel bandwidth is then shared between the Itanium bus (2.1 GB/sec) and the I/O (four channels each with a peak bandwidth of 533 MB/sec). Tenchusatsu
