AMD today announced that the power- and cost-efficient Quad-Core AMD Opteron processor Model 2356 and Quad-Core AMD Opteron processor Model 8356 now hold the top x86 web performance records for both 2P and 4P servers, as measured by the SPECweb 2005 benchmark.

The 2P Quad-Core AMD Opteron processor-based system posted a score of 30007 on an HP ProLiant DL385 G5 server featuring two power-efficient AMD Opteron processors Model 2356 running at 2.3 GHz. The 4P Quad-Core AMD Opteron processor-based system posted a score of 43,854, which represents a roughly 2.5 percent increase in performance over the previous record. This record-breaking score was achieved with an HP ProLiant DL585 G5 server powered by four Quad-Core AMD Opteron processors Model 8356, which run at 2.3 GHz and 75W Average CPU Power (ACP).

Additionally, the 4P results are among the first to be tested using a 10 Gigabit Ethernet (10GigE) network infrastructure, showing that Quad-Core AMD Opteron processors can meet the latest demands of web-based companies and emerging technology.

“Customers in massive scale out and cloud computing environments need reliable hardware with leading application performance to drive distinct business advantages,” said John Gromala, director, ProLiant product marketing, Industry Standard Servers, HP. “The record-breaking benchmark results of the HP ProLiant DL 585 G5 and Quad-Core AMD Opteron processors demonstrate the outstanding performance and reliability these solutions deliver to high-traffic computing environments.”

SPECweb 2005 is an objective and representative benchmark for measuring a system’s ability to act as a web server, simulating simultaneous user requests for standardized web transactions such as banking, e-commerce and downloading dynamic content.
