SPEC CPU2000 V1.3 (RETIRED: February 2007)

[ Information | Results | Support Issues ]

Technology evolves at a breakneck pace. With this in mind, SPEC believes that computer benchmarks need to evolve as well. While the older benchmarks (SPEC CPU95) still provide a meaningful point of comparison, it is important to develop tests that can consider the changes in technology. SPEC CPU2000 is the next-generation industry-standardized CPU-intensive benchmark suite. SPEC designed CPU2000 to provide a comparative measure of compute intensive performance across the widest practical range of hardware. The implementation resulted in source code benchmarks developed from real user applications. These benchmarks measure the performance of the processor, memory and compiler on the tested system.

SPEC CPU2000 Retirement

CPU2000 was retired in February 2007. Starting November 24, 2006, all CPU2000 result submissions for the SPEC web site were required to be accompanied by a CPU2006 result using:

  1. The same hardware, including memory size
  2. The same operating system and OS tuning
  3. Corresponding metrics: for example, if you submit
    256 copy SPECfp_rate2006, then also submit
    256 user SPECfp_rate2000
  4. Compilers and benchmark tuning may differ

As of February 24, 2007, no further CPU2000 results are being accepted for publication on the SPEC web site.

Flag Descriptions
Explanations from the testers for what all those cryptic flags in the results' notes section really mean.


SPEC CPU Benchmark Search Program
SPEC has set up a SPEC CPU Benchmark Search Program designed to encourage and recognize achievements of the academic and industrial community in providing and developing application code and datasets that could be used as components for the next version of the SPEC CPU benchmark suites (currently targeted for release as SPEC CPU2006). The search program is now closed, but historical information about the program is available along with the CPU2006 information.

If you download a result config file, does it have to match the result files next to it?
The CPU2000 Config File FAQ has the answer to that and other questions.
