NEW YORK - September 12, 2005 - During its quarterly Network Computing '05 (NC05Q3) launch today, Sun Microsystems, Inc. (NASDAQ: SUNW) announced a new family of enterprise-class x64 (x86, 64-bit) multi-core available servers which set new standards for performance, reliability and energy efficiency. Powered by AMD Opteron processors, the highest-performance x64 processors on the market, and running the Solaris 10 Operating System (OS), the new industry-standard servers are about one-third the power, one-and-a-half times the performance, and cost half as much as comparably configured 4-way servers from Dell(1).
