Intel formally introduced three 450MHz additions to its high-end Pentium II Xeon chip family. The processors come with 512K, 1Mb and 2Mb of level two cache and are aimed at the server and workstation markets. The chipset and processors will support four way symmetric multiprocessing (SMP) machines. Intel claimed that systems using the 2Mb version of the 450MHz Xeon gave 10 per cent better performance than a 400MHz Pentium II Xeon with 1Mb of level two cache. The chips cost $824 for the 512K version, $1,980 for the 1Mb version and $3,692 for the 2Mb version. ®
