Sun Fire X4170 M2 Posts Leading Score on Compute-Intensive SPECfp_base2006 Benchmark


(As of Monday, 28 June 2010)

Oracle’s Sun Fire X4170 M2 server, equipped with two Intel Xeon X5670 processors, produced the new world record SPECfp_base2006 score of 53.5. The latest version of Oracle Solaris Studio Express 6/10 compiler software was instrumental in landing this groundbreaking result.


The SPEC CPU2006 benchmark exercises a computer's processor, memory architecture, and compilers on a variety of real-world, compute-intensive workloads, and consists of two benchmark suites. One suite measures and compares compute-intensive integer performance and the other measures and compares floating-point performance. For each of these suites, two metrics are collected. One measures how fast the computer completes a single task and the other measures how many tasks a computer can accomplish in a certain amount of time (the throughput).


  • The compound effect of using the most advanced Intel Xeon X5600 processor series CPUs in conjunction with Oracle Solaris 10 and the latest version of the compiler software — Oracle Solaris Studio Express 6/10 — propelled the Sun Fire X4170 M2 server to the top position on SPEC's floating point benchmark.
  • OS and compiler software often help to deliver the best performance by providing optimizations tailored to a specific hardware platform or microprocessor architecture. The advanced features of Oracle Solaris Studio Express 6/10 compiler software allowed the Sun Fire X4170 M2 server to produce outstanding results: A SPECfp2006 score of 57.6 and a SPECfp_base2006 score of 53.5, respectively.
  • The base scores are produced using less optimized benchmark binaries that were compiled under stricter guidelines. Although "base" scores may not reflect the ultimate performance of the system, some end users, who may prefer to spend less time tuning their compiler optimizations, may find them more appealing.
  • The Sun Fire X4170 M2 server outdoes the competing x86 server, the IBM System x3650 M3, with the SPECfp_base2006 result of  which was running SuSe Linux Enterprise Server OS and Intel compiler software, by 17%.
  • Additionally, the Sun Fire X4170 M2 server beats the best POWER7-based SPECint_base2006 result of 44.5, which was posted by the IBM Power 780 server. This further demonstrates the superior capabilities of Oracle Solaris 10 and the Oracle Solaris Studio Express 6/10 software release, which includes the latest features and capabilities, against IBM’s AIX OS and XL compiler software.
