SuperPI 32M is a relative "quick" way to test CPU and system speed and stability

Click these two links for result tabulation:
Different core performance results in SuperPI 32M (post 3 and post 4)
Analysis of different core performance in SuperPI 32M (post 308)

SuperPI 32M is a relatively "quick" way to test speed and stability of CPU, memory and system. SuperPI 1M does not stress the CPU, memory and system enough. System that passes SuperPI 1M may have a hard time passing SuperPI 4M, 8M, 16M and 32M.

For SuperPI 32M, in additional to CPU frequency, memory frequency, memory timings affect the total time as there is heavy memory access throughout the computation. I think system paging is also involved (to some extent depending on total memory size of the system), so the chipset and the system bus are involved. Unlike the small FFT in Prime95 (8K - 32K), only the CPU and the caches are stressed. The large FFT (1024-4096K and blend) in Prime95 can test both CPU, memory and system (paging) also, and certain Prime95 setup can stress the CPU, memory and system more with extensive testing in time.

SuperPI 32M runs longer (20 - 30+ min. depending on CPU processing power), requires more memory (~ 268 MB compared to 8.4 MB for SuperPI 1M) and system resources, and tests the CPU, memory, system and their stability more than that offered by SuperPI 1M which completes in a much shorter period of time (about 20 - 30 sec).

Please post these results (format shown in second post of this thread):

- CPU model, stepping code, week code (stepping and week code are printed on the CPU)
- memory information (frequency, tCAS, tRCD, tRP, tRAS, cmd_rate, voltage)
- motherboard information
- cooling
- operating system

Screen shots of
- CPU-Z CPU tab
- CPU-Z memory tab (run CPU-Z twice will give two windows and then select different tabs)
- SuperPI 32M
- A64 tweaker (optional)

Please use the format suggested in the 2nd post to provide data for result tabulation and to keep result listing uniform. Results with missing data may not be included.

Systems with Intel processors, unix-favor, ... are welcome too :)
Please refrain from posting comments or questions to keep the thread simple and mainly for results only.

Stability testing using memtest, SuperPI (32M) and Prime95


Download, history and credits:

The original X86 executable is dated back to 23/09/1995, and it is still being widely used and downloadable as SUPER_PI.EXE. Do a search will find sites for downloading it.

Quoted from SUPER_PI.TXT of the SUPER_PI package:

"In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi and he collaborated with Dr. Y.Kanada at the computer center, the University of Tokyo. This record should be the current world record. ( Details is shown in the windows help. ) This record-breaking program was ported to personal computer environment such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes within 3 days with Pentium 90MHz, 40MB main memory and 340MB available storage. The software is free and the circulation of program is also free!"

Links to the very original source:
http://www.super-computing.org/
ftp://pi.super-computing.org/windows <- e.g. Windows user, download "super_pi.zip", unzip the package and run super_pi.exe
ftp://pi.super-computing.org/Mac_OSX
ftp://pi.super-computing.org/Linux
ftp://pi.super-computing.org/Itanium_Linux
ftp://pi.super-computing.org/AIX_Power3


Use either these two versions here for speed reporting and stability testing:

1. The above original (version 1.1) for general testing for speed and stability, to avoid potential problems of the "mod" version in certain setups and processors.

2. The following "mod" version only for tweaking as it can show milli-second resolution or for validation if needed. If it runs ok, it may be used for speed reporting and stability testing here.


Thanks to Gautam and d]g[ts for providing the link to this "mod" version.
d]g[ts said:
http://superpi.radeonx.com/ <- Link taken from XS froum. original thread there linked HERE
this is a version that supports millisecond times, and can be validated via checksums. Also has anti cheat feature to where it cannot be patched.
Some (credit to nicknomo and c267267) reported that the "mod" version may not work for certain processors and setups.

There are also "mod" version (optimized) for AMD SSE2 and Intel SSE3, DO NOT use these version here for speed reporting.

Hope the 64-bit version will be available (if not already).

Comparing various CPU cores based on SuperPI 32M run time

Here shows the relative performance of various CPU cores from Pentium to A64 to AXP normalized to
- CPU frequency
- CPU and memory frequency (about equal weight on the frequencies)
based on SuperPI 32M which tests CPU, cache, memory.

Performance is measured by 1 / SuperPI_32M_run_time

Score1 = Performance / CPU_freq
Score2 = Performance / (CPU_freq + 10 x memory_freq) ..... CPU and memory would have about equal weight

It shows the amount of computing power per MHz of CPU and memory.
E.g. some cores can deliver higher frequency, but the performance per MHz is much lower.

SuperPI_32M_vs_CPU.JPG


SuperPI_32M_perf_per_clock_vs_CPU.JPG


Watch how the yellow bar trending downwards in the last graph as performance clock for clock decreases.


Next the same data sorted by CPU type is shown.

As can be observed, for the same CPU type, the frequency-normalized performance measured centers around a certain value regardless of the frequencies of the CPU and memory.

SuperPI 32M Performance per CPU frequency of different CPU cores

SuperPI_32M_perf_per_clock_avg.JPG


The 3rd column shows relative measure to Barton (100%) based on SuperPI 32M on CPU frequency.

It becomes apparent that clock for clock (would like to see more data points to further refine the numbers),
- San Diego performs better than ClawHammer (~4%)
- Venice performs better than Winchester (~4%)
- Venice performs better than NewCastle (~5%)
- ClawHammer performs better than NewCastle (~2%)
- various A64 perform better than Barton/Tbred B (13-24%)
- Barton performs better than Tbred B (~4+%)
etc.

Remark: Sample size may not be large enough and tests not controlled.
SuperPI 32M run time analysis has not been adjusted for variations such as OS, memory size, timing.

My Partition D: WINDOWS Me:

I get an error sraight away for both v1.1e AND 1.4 dfor 32M, 16M crashes after a couple of minutes, could be my system is unstable, will try with my other RAM sticks, and then edit this post.

edit: I put in another RAM stick that I previously tested extensively, lowered my overclock significantly, and bam - 32M worked even under Windows Me.

Thank you hitechjb1 for helping expose that many of us may be running unstable systems after all.

Help,
today, I default all the bios setting (all default, all auto) and I run the super pi . I got a error (1M).. what's wrong with my computer.. got error when I run it in default setting?? the error message is :NOT EXACT IN ROUND

This is because the system is overclocked to a level more than some components can handle or some settings are not set properly, most likely the CPU, or the memory (or maybe something else). As a result, computation errors were detected. You may have to reduce either the CPU or memory frequency or relax the memory timing or a combination of them, and readjust the system settings such as HTT, memory timing, memory_HTT_ratio, ....

If you have further question, please create a new thread (as this thread is intended mainly for posting SuperPI 32M results), list your detailed components and settings, and many of us would be more than happy to help to optimize your system to its full potential.

As you can see, SuperPI (32M) is a good testing vehicle for CPU, memory and system speed and stability.
 
well, i thought id get a faster time with this, but it was my very first run at it, would tweeking help at all? or is it just raw cpu cycles that are needed for this proggy?
