<a name="anchorDescription" />Description
The CPUID benchmark uses special CPU instructions identify the type of CPU and to measure speed in MHz. Then it executes add instructions via 1, 2, 3 and 4 registers to identify maximum speeds of integer, floating point and MMX areas. Version 2.0 includes tests for SSE, SSE2 and 3DNow instructions, when available. Version 2.0 also includes double precision floating point calculations besides single precision. These generally produce the same speeds but are provided to compare with results of the new instructions. Pre-compiled versions of the benchmarks can be found in WhatCPU.zip which also contains the source code and more detailed explanations. See also My Main Page for other PC benchmarks and results.
Performance is measured in terms of Integer Millions of Instructions Per Second (Integer MIPS) and Millions of Floating Point Operations Per Second (MFLOPS). For MMX instructions, that use 64 bit registers, Version 1 showed MMX MIPS. As two 32 bit integers are added via one instruction, new results are twice those in Version 1, with a different definition.
A version compiled to run at 64 bits via WinXP x64 is also available. See Win64.htm and below. As this measures 64 bit Integer MIPS and 32/64 bit SSE2 Integer MIPS for comparison purposes, Version 3 of the 32 bit variety was produced to include the latter. This also includes changes to the configuration information. See Example Log File. Where available, the additional SSE2 speeds are included with the results (see +3 in Contents). These benchmarks are in Win64.zip.
Further 32 and 64 bit versions are available to demonstrate performance of up to 4 processors. See DualCore.htm and below. The benchmarks are in DualCore.zip.

<a name="anchorModel" />Model Code
The last three digits of the model code (originally known as Family, Model, Stepping) can be as follows. Some models are not shown. Intel Xeon, Celeron and AMD Duron, Sempron etc. can have the same CPU core as other processors and have the same model identification. Later AMD CPUs use more than 3 digits. At this time it became difficult to obtain details of the AMD Model Codes for the vast array of different processors produced. The codes for most Opterons, Semprons, Turions and Athlon 64 FX and Mobile CPUs are not shown as they can be the same as Athlon 64.
The Model Codes reflect the manufacturing process and updates (Stepping) and is now of little use for identifying CPUs. All recent CPUs have an additional ID string which identifies the model such as:

The following relative efficiency comparisons of 32 bit Integer MIPS, Double Precision MFLOPS and 64 bit MMX Integer MIPS have been converted to assume that the CPU runs at 100 MHz. Whereas variations of 5 MIPS or MFLOPS will be due to timing complications, larger differences indicate some architectural change. Pentium Pro is the same (except no MMX) as early Celerons, Pentium II and Pentium III. Similarly, AMD Durons and Athlons have the same core.

<a name="anchorCompare2" />Comparison Versions 2/3
For Version 2 of the benchmark, relative efficiency comparisons are provided for 32 bit Integer MIPS, 32 bit MMX Integer MIPS, 32 bit Single Precision MFLOPS, 32 bit SSE MFLOPS, 32 bit 3DNow MFLOPS for AMD, 64 bit Double Precision MFLOPS and 64 bit SSE2 MFLOPS. This time results have been converted to assume that the CPU runs at 1000 MHz. A rating of 1000 MIPS or MFLOPS indicates that a CPU is executing at 1 i386/i387 instruction per clock cycle.
32 bit Integer MIPS - The instruction count for this includes those for loop control (10% extra). So, adding to one register can give a score of 1100. Early Pentium 4 CPUs indicate greater than 2000 for this test, the processor having capabilities to execute two integer instructions per clock cycle. Maximum, using 4 registers, is greater than 2000 for the latest CPUs, except Pentium/Celeron M.
32 bit MMX Integer MIPS - With a single pipeline operating on two 32 bit integers in 64 bit registers via SIMD action, a score of 2000 could be expected, as on Pentium 4. Later AMD processors obtain 4000, indicating two pipelines. MMX instructions use floating point pipelines.
32 bit Single Precision MFLOPS - Of the modern CPUs, Celeron/Pentium Ms are best on adding to a single register at 333 MFLOPS on a 1 GHz processor, followed by AMD at 250. AMD processors are best adding to 4 registers, running at 1 FP add per CPU clock cycle.
32 bit SSE MFLOPS - these SIMD instruction add four independent 32 bit floating point numbers with one instruction via 128 bit registers. Adding to one of these is faster than using 4 normal FPU registers on Intel CPUs but equal in AMD’s case. Fastest speeds shown are with MFLOPS at two times MHz.
AMD 32 bit 3DNow MFLOPS - These use 64 bit MMX registers but maximum speeds are the same as SSE.
64 bit Double Precision MFLOPS - As expected, MFLOPS are the same as adding 32 bit numbers.
64 bit SSE2 MFLOPS - Using the same 128 bit registers as SSE, with 2 adds per instruction, measured speeds are half those for SSE. On AMD processors, maximum speed is the same as using normal FPU instructions.
