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!"

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.
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).

Some (credit to nicknomo and c267267) reported that the "mod" version may not work for certain processors and setups.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.
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).
