Roy Longbottom at Linkedin PC CPU Performance Comparisons

From Roy Longbottom's Benchmark Results

Summary

The document contains tables of CPU performance from 80486 to Intel Core i7 and AMD Phenom II, including speed via caches and RAM derived from my benchmarks and results reports, which are available from Compuserve PC Hardware Forum and my web site.

More Historic Data

In analysing results of the different benchmarks, in virtually all cases (except for RAM), CPU speed, including using data in cache, is shown to be proportional to CPU MHz for a particular type of processor. So it has been decided to show the MHz of available CPUs and provide simple tables with one set of numbers for each type of CPU. For results depending on memory speed, results are provided for a range of RAM types.

As the number and type of instructions used in the benchmarks is known, performance results can be easily converted to Millions of Instructions Per Second (MIPS) or Millions of Floating Point Operations Per Second (MFLOPS). Comparison numbers represent percentages of MIPS or MFLOPS divided by CPU MHz.

1. CPU Performance Tables - Introduction

In analysing results of the different benchmarks, in virtually all cases, CPU speed, including using data in cache, is shown to be proportional to CPU MHz for a particular type of processor. So it has been decided to show the MHz of available CPUs and provide simple tables with one set of numbers for each type of CPU. As the number and type of instructions used in the benchmarks is known, performance results can be easily converted to Millions of Instructions Per Second (MIPS) or Millions of Floating Point Operations Per Second (MFLOPS). Comparison numbers represent percentages of MIPS or MFLOPS divided by CPU MHz.

CPUs can have more than one Integer or Floating Point Pipeline where each might be able to produce one result per Hz. The first Intel Pentium 4 Integer Pipelines could execute two instructions per cycle. Then there are MMX, SSE and SSE2 Single Instruction Multiple Data functions, using 64 or 128 byte registers, where 2 to 4 calculations can be carried out simultaneously. Furthermore, with floating point, linked add and multiply instruction can produce two results per clock cycle for each register element (SSE up to eight 32 bit calculations per clock). The net result is that the percentage calculations can be greater than 100.

Overall processor performance depends on the type/version and speed of CPU and cache sizes along with memory speed, which is dependent on the system board used. No attempt is made to provide an overall performance rating, the overall aim being to show some strengths and weaknesses of each type of processor.

The introduction of the Intel i7 processor leads to a major complication as it does not necessarily run at a constant GHz speed. In the event of only one processor being used, and it is not too hot, a Turbo Boost function increases CPU GHz. A reducing speed increase using 2, 3 or 4 CPUs can also be applied (see Turbo Boost from Contents table). In the results tables, two percentage calculations are shown based on normal and boosted speed.

Some information on Cyrix CPU Characteristics is also included.

Note that these benchmarks reflect performance of one CPU on multi-core processors.

2. CPU Characteristics

Some of the following have been gathered from benchmark results and magazines and may not be completely accurate. Mobile CPUs have the same speeds using mains power but might have diferent size L2 caches and slower RAM.

A special CPUID assembly code instruction enable details of processor characteristics to be obtained including model codes. These codes were originally three hexadecimal digits known as Family, Model and Stepping, the latter digit showing changes for minor bug fixes. An extra Extended Model digit was included later. Different types of processor, such as Pentium, Celeron and Xeon, have the same Family and Model codes, which invariably means that the core CPUs have identical performance characteristics (cache sizes and connectivity will be different). Later, CPUID functions produce the processor marketing name and model.

Intel model codes are readily available via their “Processor Spec Finder” but the equivalent AMD pages only show marketing model details. In most cases, the model codes can be found in FAB51 Reference Guides or PDF documents for Processor Revision Guides or Power Data Sheets.

3. Benchmark Results Used

CPUID (WhatCPU.zip) has tests using 1, 2, 3 and 4 registers, simply adding 1. Tests are on integers, 32 bit SP and 64 bit DP floating point, MMX 32 bit integers, SSE SPFP, 3DNow SPFP and SSE2 DPFP. Assembly code loop has 20 adds and decrement/jump. The latter are included in instruction count for integer speed.

BusSpd2K (.zip) is read only using streamed sequential integer data using 64 AND from memory integer instructions and 512 MMX MOV 64 bit instructions in the assembly code timed loops. The MMX test is intended to show maximum data transfer rate from memory.

RandMem (.zip) uses C code with of eight & xi[xi[i+0]] | xi[xi[i+2]] statements (FP +, -, *) reading data or eight xi[xi[i+2]] = xi[xi[i+0]] statements for read/write. The pair are used for reading/writing 128 bytes in the loop with the indexing producing either sequential or random accessing. Four tests cover 32 bit integer operation and four 64 bit double precision floating point. With indexing calculations, this benchmarks has more instructions per word read or written than the other memory tests. Data transfer rate may be less but the MIPS/MHz ratio higher.

BenchNT.zip provides Whetstone, Dhrystone, Linpack and Livermore Loops Classic benchmarks, representing old code much with a small number of instructions in loops. Benchmark codes are provided compiled with full optimisation and no optimisation.

SSE3DNow (.zip) uses the same read and read/write functions as MemSpeed - C code - s=s+x[m]*y[m] and x[m]=x[m]+y[m]. The tests are run via the C code in Single Precision Floating Point with 16 unrolled statements in the inner loop (read 128 bytes, read/write 64/64 bytes). When available, the tests are also run using assembly instructions for SSE (SP), 3DNow (SP) and SSE2 (DP) handling the same amount of data in the inner loop.

FFTGraf (.zip) calculates Fast Fourier Transforms using single and double precision floating point numbers. Version 1 uses optimised C code with later versions using assembly code instructions. Memory accessing is on a random/skipped sequential basis where performance suffers due to burst reading from RAM. Earlier systems read in 32 byte bursts with later ones using 64 bytes with potentially slower speed on this and RandMem benchmarks.

BusSpd2K, RandMem and SSE3DNow run tests with increasing memory demands to measure performance via caches and RAM. Similarly, FFTGraf uses increasing FFT sizes.

Note: assuming CPUs of the same MHz, Pentium 4 is faster than AMD 64 on only one example and AMD CPUs have larger L1 cache. Pentiums could also be faster than P4s, probably due to shorter pipelines. Pentium 4E has even longer pipelines and performance characteristics are different to earlier P4s, some tests producing slower results and others faster. Pentium M/Celeron M and Core 2 Duo CPUs show superior performance to the P4 range on many of these tests, influenced by shorter pipelines.

This is the first example with i7 results, mainly showing exceptionally good MIPS/MHz results if we were unaware that the processor is running at a higher Turbo Boost speed. Assuming that all tests are run at the elevated speed, on the basis of these comparisons, the i7 processors are no better than those for Core 2 and much worse in two cases, maybe due to the particular code used in the benchmarks. The first is using BusSpd2k streaming data from L1 cache and ANDing to the same register. Here, performance has degraded to old Pentium standards, where ANDing to two registers is twice as fast. The other case is reading and writing using RandMem, where performance has returned to Pre-Core 2 levels.

Results for a newer i7, running at the same GHz, have been added, but this has lower Turbo Boost frequencies. However, it shows some significant improvement in tests involving reading/writing (RW - comparing #3 and #1).

The Phenom II performance profile is at least as good as earlier AMD processors. Adding Turbo Boost would make it faster than i7, based on average speed of these tests.

AMD CPUs show superior performance to P4 of same MHz on all these floating point tests, average 1.9 times. They also have a larger L1 cache. Pentium M/Celeron M and Core 2 Duo CPU scores are similar to AMD’s but L1 cache sizes are smaller. The Phenom II profile is a little better than earlier processors and at least comparable to i7 boosted MFLOPS/MHz.

Assuming that the CPU is running at Turbo Boost GHz, i7 performance characteristics are similar to Core 2 but there is some degradation with reading and writing using SSE3DNow, corrected on the newer 930 model. Core i7 #1/2 was probably running at a lower Turbo Boost level for the FFT tests, but would also be affected by the slow read/write performance.

Again AMD performance is superior to P4s but similar to Pentium M/Celeron M. When introduced, Core 2 scores were by far the best on these SSE/SSE2 tests. Again assuming i7 run at Turbo Boost GHz, speeds reading cached data are comparable to Core 2 but slower when reading and writing.

AMD performance on SSE/SSE2 has been doubled with Phenom, in some cases and is, on average, as good as i7 Turbo Boost on the basis of MFLOPS/MHz. Again, Core i7 #1/2 was probably running at a lower Turbo Boost level for the FFT tests but would also be affected by the slow read/write performance.

Pentium 4 is faster than AMD CPUs of the same MHz up to Athlon XP on these L2 cache tests. Athlon 64 shows improvements on these speeds. Core 2 Duo is better than both P4 and Athlon 64 on most tests and has a much larger L2 cache.

Relative Turbo Boosted i7 to Core 2 results are similar to those using L1 cache, with RandMem reading and writing being much slower. All Phenom speeds are faster than older AMD processors, L2 cache efficiency being much higher, and MIPS/MHz calculations are now better than i7 using Turbo Boost. Phenom and i7 speeds via L3 cache are also shown. See above comments for slow Core i7 #1/2 results for reading/writing.

Latest AMD CPUs have similar average performance to P4s of the same MHz, the former benefiting from faster floating point and the latter from more efficient L2 cache. Pentium M/Celeron M are relatively better but top marks go to Core 2 Duo.

The new i7 processor has similar characteristics as Core 2, assuming that Turbo Boost is used. The more efficient L2 cache improves Phenom relative score with some better than i7. With data in L3 cache, the i7 has the edge. See above comments for slow Core i7 #1/2 results for reading/writing and with FFTs.

Performance of these SIMD streaming instructions is superior on the P4 versus AMD CPUs of the same MHz. Athlon 64 shows improvements over earlier AMD CPUs. Again, Core 2 Duo was best at the time. Core i7 provides further relative gains and is still better than the vastly improved Phenom. This relativity is increased further with data in L3 cache. See above comments for slow Core i7 #1/2 results for reading/writing and FFTs.

 XX - slow nForce 570 chipset on some tests


Comparing CPUs of the same MHz and the same memory speed, P4s show superiority performance of speed via data in RAM compared with AMD with CPUs prior to Athlon 64. Core 2 Duo performance is outstanding on some of these tests but poor on others, perhaps due to using the nForce 570 chipset. Later results via Intel 965 chipset confirmed this suspicion, giving rise to Core 2 Duo with DDR2 RAM taking the lead on performance at that time.

This i7 with DDR3 RAM pushes this processor into the lead with data in RAM. Core i7 #1/2 RAM is faster but see above comments for slow results for reading/writing. The Phenom shows more significant improvements but MIPS/MHz is slower except for one test.

Superior floating point performance with AMD CPUs helped to overcome inferior RAM speeds compared with Pentium 4. Except for those from nForce 570 chipset, Core 2 Duo scores came out best. Core i7 provided further gains in relative speeds and Phenom improvements failed to close the gap in many cases.

These results could justify that a 2 GHz Athlon 64 is equivalent to a 3 GHz P4 when running SIMD streaming instructions with data in RAM. Yet again, with the nForce 570 chipset, Core 2 Duo results were very poor but other chipsets showed Core 2 as the best yet. Again, The i7 produced further improvements as did the Phenom but the former rules the roost. Note once more that Core i7 #1/2 RAM is faster, but see above comments for slow results for reading/writing and with FFTs.
