Summary
Separate calculations are provided, of performance, using data from CPU only or L1 cache, L2 cache and
RAM, in terms of %MIPS/MHz and %MFLOPS/MHz. based on 29 measurements from 10 of my benchmarks.
The actual count of floating point operations and most integer assembly level instructions were known.
Intel CPU types covered are from 80486 to Core i7 and K62 to Phenom II from AMD. These relate to single
CPU (or core) performance, where a specific model’s speed is normally proportional to CPU MHz, for CPU and
cache based test fuctions.
Intel 1994 to 2014 CPU specifications are from Pentium to Core i7 and equivalent Xeon (identified by CPUID
Model) with AMD from K5 to Phenom II and Opteron. These show CPU MHz range, number of cores, cache
sizes, bus and memory speeds (where available). The details can be used to help to extrapolated system
performance from the above calculations.

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

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.

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 (busspd2k.zip) is a read only benchmark 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 (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 (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 (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 (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.
Further details and results of the above benchmarks can be found in My Classic Benchmarks Project -

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.

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.
