Real-life CPU benchmarks

CPU megahertz isn't everything. On this page I have gathered some benchmarks for computers used at our department, as well as for some other computers. If you have a different computer that you would like to see in this list, let me know. The benchmarks are based on cut-down versions of programs that people have been running long enough for CPU speed to be a real issue. (I would like to have a few more programs to test with, though.) The point of these benchmarks is to show the difference between different CPU architectures (useful when buying new computers), the difference between different compiler flags (useful when compiling), the difference between machines at the department (useful when running CPU-intensive programs), and the difference between different compiler versions (mostly as a curiosity, really).

All programs have been compiled with gcc 3.2 or newer, with -O3 and a few different sets of compiler flags. The code was compiled for i686 on the 32-bit x86 systems, and for the compiler's default target on the 64-bit systems.

The table below is bit messy, but it should be fairly self-explanatory. The scores for individual tests are just 1/exectime times a factor that brings the scores into the range of clock frequencies. The overall scores are the geometric means of the individual test scores. For the first set of compiler options, the /MHz column is the overall score divided by the real frequency. When n instances of the programs were run in parallel, as shown by *n in the first column, the scores reflect the total performance, not the performance per CPU core.

For the other sets of options, the % ch column shows the change in score versus the first set of options. Red and green have been used for scores deviating much from the overall score, to point out strengths and weaknesses. Each test has been run at least three times, and the best time is used. Pink background is used for tests where the standard deviation is above some threshold, whereas blue background indicates that the test was only run once. The whole set of programs (including the PHP script that generated the main table) can be downloaded here.

For the last two sets of compiler options, the program is compiled with -fprofile-arcs, run, and recompiled with -fbranch-probabilities. The [best match] architecture is the one listed in the -march column. The possible choices depends on the compiler, and I have tried to make the script choose the one that most closely matches the hardware. In some cases a different choice may well have produced faster code.

The log() function is a source of confusion, as its implementation in glibc has changed once or twice. More generally, the performance of glibc can differ between systems depending on version and how it was compiled.

Programs
ProgramWeightDescription
HP191.0 Enumeration of all designing sequences in the HP model for N=19. Mostly data structure handling (trees) with limited RAM consumption (~2MB). No floating-point operations. (carl)
4cyc0.5 Calculation of the number of 4-cycles in Kauffman networks. Floating-point summation of a septuple-sum, with many calls to log() and exp(). (carl)
sand0.3 5-dimensional sandpile simulation with 30^5 cells. Extremely memory-intensive with random memory accesses in two 24MB blocks. (bjorn)
6cyc0.5 Monte Carlo summation of the number of 6-cycles in Kauffman networks. (bjorn)
6c_ld0.5 The same as 6cyc, but with long double instead of double. (bjorn)
hair1.0 All-atom MC simulation of a beta-hairpin (244 atoms). Lots of floating-point operations, limited memory consumption. (anders)
canal1.0 Counting cycles in boolean networks with nested canalyzing rules and a power law connectivity distribution. (carl)

Some computers have changed names, hardware or OS since they were tested, the this page might not be entire up-to-date or self-consistent. davies (not davies.thep.lu.se) is my Linux box at home, and at the moment it's the only non-department machine in the list. base2, sauron and base2 are BASE servers of various sorts. selma is part of the new cluster in the basement. The hardware of selma and base2 is identical except for the CPU frequency, and the discrepancy in performance per MHz is mostly caused by differences in glibc version or compilation. selma runs ubuntu edgy and base2 runs openSUSE 10.2.

The Athlon XPs in salman and the current davies have Palomino cores. dylan is a Barton 2800+ with its weird identification string. leo appears to be a Clawhammer (OPN ADA3500DEP4AS). b>lev is a San Diego (OPN ADA3700DKA5CF) whose greater L2 cache unfortunately has little impact on any of these tests. Some of the 64-bit machines are running in 32-bit mode, due to some odd problem with SuSE 9.3. nabokov, bob and beckett are Venices of a newer stepping (OPN ADA3500DAA4BW). The older P4s (whitman, c3, oe, saramago) are HT-able Northwoods running without HT. The newer machines james and tom are Prescotts (model number 530) running with HT. The old jersild and auster were stolen and replaced with Newcastle Athlon 64s.

There are some clear differences between the different processor architectures. The Athlons are generally about as fast compared to older Pentium 4s as their ratings suggest, but there's a nice extra boost to be had from running in 64-bit mode. There's a general trend towards doing more work per CPU cycle, with the exception of that whole Netburst excursion. Prescott is really as slow compared to earlier cores as has been reported, but on the other hand HyperThreading works quite well on it, with a boost of about 20%. The dual and quad core machines show excellent scaling with the number of processes, except in the bus-abusing sandpile test.

The sandpile test just shows the importance of low-latency RAM and that CPU frequency has improved faster than memory speed. If any conclusions can be drawn from the different compiler flags, it's that -ffast-math should be used unless there's some specific reason not to, and that -fomit-frame-pointer -maccumulate-outgoing-args generally gives faster 32-bit code. Profiling for branch prediction makes a rather large difference for a subset of the programs, but it can also make code run slower. Compiling for a specific architecture seems mostly to matter for 32-bit code on 64-bit CPUs.
