The parenthesis around a group of test results, such as (75-78), indicate that these tests were averaged independently as a single test so as to not give too much weight to any one benchmark program.
The ALU chart contains the average of tests 5, 8, 20, 22, 59, 65, 67, and (75-78), the results of which have been tabulated in Appendix 4 under test Integer. The normalised values from Appendices 3-4 have been averaged and multiplied by 100 to be more pleasing to the eye. The bar chart in Appendix 5 shows the integer-only, or algorithmic logic unit (ALU), performance in descending order for each CPU, including the normaliser Pentium 100 CPU, which by definition will always have a value of 1.0 x 100. In cases where the tests contained units of seconds, the values were inverted to reflect an increasing trend with increasing performance. For the overall performance, an IBM/Cyrix 5x86-133 was the fastest commonly available CPU and was equivalent to a Pentium 100, however if you are lucky enough to own an AMD X5-133/160 which overclocks well at 200 MHz, this configuration would be the fastest possible for ALU-specific and overall tasks.Īppendices 1-2 tabulate the raw data computed from the employed benchmark programs, while Appendices 3-4 tabulate the data normalised to that of a Pentium 100. An IBM/Cyrix 5x86-133 (and perhaps an Intel POD-100-WB, if stable) was the fastest commonly available CPU for FPU-specific operations and was approximately equivalent to a Pentium 90. An appropriately configured IBM/Cyrix 5x86-133 and an AMD X5-160 were the fastest commonly available CPUs for ALU-specific operations and were approximately equivalent to a Pentium 100. Depending on your computing goals, the answer may vary. It is commonly asked what the fastest socket 3 486 CPU is. 2018): If you are looking for more of a 3D graphic intensive benchmark comparison performed on the socket 3 platform, you may wish to view this supplemental thread, Voodoo 1 vs. The combinations of these tests are averaged in the Overall Performance chart.ĮDIT (Nov.
#Cpu benchmark comparison test windows#
This methodology was decided upon as some applications are heavily ALU-specific, as with general clickidy-click Windows use, while others are largely FPU-specific, as with 3D games and mpeg/mp3 playback. The test results are broken down into ALU, FPU, and overall performances. The names of the employed benchmark programs, and of which tests were run, can be found on the charts in Appendices 1 2. The intent was to identify each CPU's relative performance to that of a Socket 5/7, Intel Pentium 100 (P54C). It is believed that this work is the most comprehensive 486 comparison to-date. In this study, 28 socket 3 CPUs were tested under identical conditions using 23 different benchmark programs.
