+3 Includes Version 3 SSE2 Integer MIPS


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. Also, the benchmarks have been ported to Linux. See Linux Results below.

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:

Intel(R) Core(TM) 2 CPU 6600 @ 2.40GHz or
AMD Athlon(tm) 64 X2 Dual Core Processor 4200+

Comparison Version 1

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.

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.

32 bit SSE2 Integer MIPS - Version 3

64 bit SSE2 Integer MIPS - Version 3

Core i7 CPUs have Turbo Boost, where the CPU can run at a higher GHz when required. It appears to be a permanent fixture running these tests. Two sets of results are given for this processor at rated and Turbo Boost GHz.

64 Bit Version

See Win64.htm. This shows that adding 64 bit integers runs at the same speed as with 32 bit numbers, the latter using 32 bits of the same registers. I387 floating point and MMX instructions are not supported with 64 bit working and SSE/SSE2 has to be used instead. SSE2 32 bit integer adds can be faster than using MMX but maximum speed is the same. SSE2 64 bit integer adding speed is half that at 32 bits and is slower than using normal registers (with these tests).

Dual/Quad Core Version

See DualCore.htm. The benchmark uses an integer test and a floating point test. They are first executed separately, followed by together in two threads of equal priority and finally with two of each type, where three are at a lower priority. With a dual CPU, performance with two threads should be similar to that of the stand alone runs. The total speed of four threads might give some variation on the latter. Results now include some for a quad processor where two integer tests and two using floating point are executed simultaneously.

Dual/Quad Core Results

The following results are averages of the three test passes.

At this time there are outstanding queries on Core i7 results. On running the 64 bit single processor version, measured CPU MHz was 2809. Speeds with 32 bit SSE MFLOPS and 32 bit Integer MIPS (4 Register tests) were 1.45 times faster than on a 2400 MHz Core 2 processor, suggesting that the i7 was running at around the expected Turbo Boost frequency of 3466 MHz.

With the later i7 quad core tests, CPU MHz was measured as 2862. Then single processor tests for 32 bit SSE MFLOPS and 32 bit Integer MIPS were 25% faster than the Core 2 processor, indicating that the i7 might be running at 3000 MHz. The four CPU test was also slower than expected, with a total throughput only 3.3 times faster than on a single CPU. Note that this i7 can run at up to 2933 MHz using four CPUs with Turbo Boost and 2933/3466 x 4 is also approximately 3.3.

Eight Thread Version

This program is the same as the Dual/Quad Core Version except it is run with 1, 2, 4, 6 and 8 threads. It was produced to see the effects of Hyperthreading on the four core Core i7 where HT increases the apparent number of CPUs to eight. As with the dual core version, the tests use the same assembly language instructions to measure performance of programs compiled for both 32 bits and 64 bits. So, approximately the same speeds should be expected from the two compilations. For more details and Hyperthreading results with other benchmarks see Quad Core 8 Thread.htm.

Log File 8 Thread Benchmark

Hyperthreading does not appear to lead to much more processing capacity for this particular benchmark - eight thread totals not much higher than four thread results.
