Sun Fire X4270 M2 is the Fastest x86 System on SPECfp2006 Benchmark


(As of Tuesday, 15 February 2011)

Oracle’s Sun Fire X4270 M2 server, equipped with two Intel Xeon X5690 processors, produced the new x86 world record SPECfp2006 score. The latest version of Oracle Solaris Studio 12.2 compiler software was instrumental in achieving 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 advanced features of Oracle Solaris Studio 12 compiler software allowed the Sun Fire X4270 M2 server to produce outstanding results: A SPECfp2006 score of 64.2 and a SPECfp_base2006 score of 59.2, respectively.
  • OS and compiler software often help to deliver the best performance by providing optimizations tailored to a specific hardware platform or microprocessor architecture. The compound effect of using the most advanced Intel Xeon processor 5600 series CPUs in conjunction with Oracle Solaris 10 and the latest version of the compiler software — Oracle Solaris Studio 12.2 — propelled the Sun Fire X4270 M2 server to the top position on SPEC's floating point benchmark.
  • The new world record on SPECfp2006 benchmark, which measures server performance on a variety of real-world, compute-intensive workloads such as molecular and fluid dynamics, weather modeling and speech recognition, beats the competition by over 30 percent and extends Oracle’s leadership in these important performance areas.
  • Specifically, the Sun Fire X4270 M2 server outdoes the competing x86 server, the IBM System x3650 M3, with a SPECfp2006 result of 48.9 and surpasses the Dell PowerEdge R610 server, with a SPECfp2006 result of 49.3.
  • Additionally, the Sun Fire X4270 M2 beats the best POWER7-based SPECfp_base2006 result of 44.5, which was posted by the IBM Power 780 server, by 33 percent. This further demonstrates the superior capabilities of Oracle Solaris 10 and Oracle Solaris Studio 12.2, which includes the latest features and capabilities, compared to IBM’s AIX OS and XL compiler software.
