iCOMP Index

The Intel Comparative Microprocessor Performance Index is a computer benchmark, compiled by Intel to make them comparable to the performance of different processor models and lines for the customer. The iCOMP was introduced in 1991. The performance of the i486SX at 25 MHz than 100 has been defined. With the Pentium 4 Intel moved to the use of megahertz numbers for classification. The iCOMP was used by Intel for XScale processors.

Versions

ICOMP 1.0

1991 with the introduction of Intel i486SX Intel introduced the index iCOMP first time, so as to facilitate the comparison between the different processor models, from i386sx to. The focus was on 16 - and 32- bit applications. The underlying is the 486SX at 25 MHz has been defined, and the results are scaled to this being 100. With scores of 22 when 386SX 16-249 when 486DX - 50, a power bandwidth of 1:10 was shown.

ICOMP 2.0

With the Pentium MMX 1997 iCOMP was presented 2.0, which consisted only of 32 -bit applications and put a higher value on floating-point performance, since the competition (AMD, Cyrix ) significantly lagged. The value was based on an internal key from the results of the benchmarks

  • CPUmark32,
  • Norton SI -32,
  • SPECint_base95,
  • SPECfp_base95 and which was designed specifically for the Pentium MMX
  • Intel Media Benchmark

Composed. The key was chosen so that the Pentium 120, which had a value of 1000 in iCOMP 1.0, came up with 100 points. Thus, a 1:10 ratio was suggested that, was not given due to the different composition and weighting of the individual tests.

ICOMP 3.0

Since the Pentium III, differed in iCOMP 2.0 at the same clock rate, practically not from the Pentium II (presentation in January 1999 ), Intel published in the autumn of 1998 a revised scale. In addition to a modified set of benchmarks, especially emphasis was placed on testing for the new SSE instructions. As single applications of 3.0 iCOMP consisted of 6 parts

  • WinTune 98 Advanced CPU Integer test,
  • CPUmark 99,
  • 3D WinBench 99 - 3D Lighting and Transformation Test,
  • Multimedia Mark 99,
  • Jmark 2.0 Processor Test, and
  • WinBench 99 - FPU WinMark.

The basis for the Pentium II with 350 MHz was defined with 1000 points, but not officially published. The increase of 483 iCOMP 2.0 points for the Pentium II 450 MHz, 1500 iCOMP 3.0 points for the 450 MHz Pentium III should underpin the superiority of the new commands. iCOMP 2.0 values ​​for the Pentium III processors were never published.
