IBM x3755 AMD Opteron Server CPU Performance and Xcelerated Memory
The IBM System x3755 out performed the HP DL585 G2 by 10.4% using SPECjbb2005 with identical CPU and Memory configurations. This exemplifies the Xcelerated Memory Technology™ and its ability to deliver a performance advantage.
The IBM System x3755 when configured with three processors and IBM’s CPU Pass Thru card out performed the HP DL585 G2 configured with four processors by 27.7%. This illustrates the System x3755 CPU utilization advantage
The IBM CPU Pass Thru card provides a solution for potential savings with ISVs who have a licensing fee structure based on CPUs. The x3755 with Pass Thru card would provide equal or better system performance for a lower software licensing fee.
The test environment consisted of IBM System x3755 and HP DL585G2 server. Both servers ran Windows 2003 Server Enterprise Edition SP1. The IBM System x3755 specifications included 4 dual-core AMD Opteron 2.8GHz processors, 32GB(DDR2 PC5300) RAM, and a 273GB SAS hard drive. The HP DL585 G2 specifications included 4 dual-core AMD Opteron 2.8GHz processors, 32GB (DDR2 PC5300) RAM, and a 204GB SAS hard drive. Due to the nature of the benchmark tool utilized, hard drive size was not a determining factor in performance. Additional description and details can be found in Appendix A. SPECjbb2005 was installed on both servers. SPECjbb2005 is a benchmark for evaluating the performance of servers running typical Java business applications. The same test methodology and configurations of SPECjbb2005 were executed on both servers, and scores from SPECjbb2005 were used to compare IBM CPU Pass Thru card and Xcelerated Memory Technology™ memory performance.
