Explanation of benchmarks
 
Dhrystone 2.1

Dhrystone benchmark version 2.1. This benchmark shows processor's integer performance in VAX MIPS units (1 VAX MIPS = 1757 MIPS). The benchmark program was compiled using DJGPP v2.03 development system and GCC/GPP v 3.4.1 with optimization flag "-O2". The benchmark is run 4 times under IBM PC-DOS 7.1, the first result is ignored, the other three results are used to calculate the average VAX MIPS value.

 
Whetstone

Whetstone benchmark with double precision. This benchmark shows processor's integer and floating point performance in KWIPS units (thousands of whetstone instructions per second). The program was compiled using DJGPP v2.03 development system and GCC/GPP v 3.4.1 with optimization flag "-O2". The benchmark is run 4 times under IBM PC-DOS 7.1, the first result is ignored, the other three results are used to calculate the average KWIPS value.

 
Linpack 100x100

Linpack benchmark using double precision 100x100 matrix size, with unrolled loops and double precision calculations. This benchmark shows processor's floating point performance in MFLOPS (millions of floating point operations per second). The program was compiled using DJGPP v2.03 development system and GCC/GPP v 3.4.1 with optimization flag "-O2". The benchmark is run 4 times under IBM PC-DOS 7.1, the first result is ignored and the other three results are used to calculate the average MFLOPS value.

 
Doom high detail
This benchmark measures FPS performance of Doom v1.9s shareware game running demo3 demo under IBM PC-DOS 7.1. For this benchmark sound and mouse are disabled, screen details are set to "High", screen size is set to full screen with a status bar (one level before max screen size). The results are taken four times, the first result is ignored, three remaining results are used to calculate the average FPS.
 
Doom low detail
This benchmark measures FPS performance of Doom v1.9s shareware game running demo3 demo under IBM PC-DOS 7.1. For this benchmark sound and mouse are disabled, screen details are set to "Low", screen size is set to full screen with a status bar (one level before max screen size). This benchmark is running immediately after Doom (high detail) benchmark, the results are taken three times, the average of these results is the final number.
