We've had two of these threads (2005 and 2007) befofe about this simple benchmark, SuperPI. Actually amazing to see how quickly technology has gone forward ;) In 2005 it took a serious PC to get under 2 minutes ....

I've just downloaded and tried 2M places on a few machines. Also got results from some of my older machines in the two threads pointed out above :

Core 2 Quad Q9300 2.5ghz, 4GB RAM (desktop) = 47sec

Core 2 Duo T8300 2.4ghz 2GB RAM (laptop) = 52sec

Intel Atom 1.6gh 1GB RAM (netbook) = 3m 30sec

Pentium 4 1.8ghz 256MB RAM (desktop) = 5m 16sec

Intel Celeron 2.0ghz 512MB (desktop) = 8m 50sec

Pentium 4 3.0ghz HT 1GB RAM (desktop) = 1m 50sec

Intel Celeron D 1.6ghz 512MB RAM (desktop) = 2m 00sec

do the 1M pass

i did it lastnite and got 11.8secs

Everything is done with 2M on all those PC's (as were most done in 2005). 2M gives a comparison. Why don't you redo at 2M?

Also what processor/RAM?

ill do a 2M tonight when i get home.

check my sig for cpu/ram info
 
@ 2m my AMD 3200+ (939) did super PI is a blistering 02m 24s!!! I know I know, it's really not the most insane times, but this processor is 3 years old and it's clocked @ 2ghz :P
 
The best I got was 38 :-( Expected better from a dual X5450! Don't think the app likes multiple processors....
 
I only found the SuperPi mod version which I think is multi threaded, where can I find the normal one? (Sorry, I'm not completely knowledgeable with any sort of benchmarking yet as I'm using a junk system ATM, will get more into it at around April :D)

No multi threaded versions that i have seen so far, care to provide a link ?
 
Does your file name for superpi also say super_pi_mod-1.5?

LOL! SuperPI is a single threaded application dude

I know;-) Bit disappointing actually. It would be nice to have a multi threaded one though.

HyperPi is the GUI for superPI; it allows you to run a separate instance of the application, e.g. 2M, across each processor at the same time. What we need is an application that runs a single instance across all the cores.

Guest 38 seconds is the best I'm going to get....

but that would mean we would need up to 32M to get accurate times... but that would show how good the communication between each of the cores... but it that instance, having a higher cache on the cpu will matter more then architecture sadly

Mmmmm, right, not sure I follow you here....

Just to make it clear, the HyperPI runs 2 or 4 or 8 independent processes, one on each processor. This could be useful for testing each CPU, but it does not alter the result per CPU. I tested on one CPU and got 38 seconds, two concurrent CPUs 38 seconds, three concurrent 38 etc, right up to eight.

I believe so, cannot check on that system at the moment but i believe it is the latest according to google.

Ram and cache affect superpi the most is what i have seen from most oc'ing sites
 
Super PI version you'll wanna use is SuperPi 1.5 (XS) reason being its the most popular Pi version used for all overclocking competitions, hardware reviews etc... Most popular tests are by far 1M, then 32M then 8M test, everything else is ....
and yes Super Pi 1M is cache sensitive, very much so, and also ram timings and bandwidth. If you want something similar but multi threaded (any number of available threads) use Wprime version 1.5. there's 32M and 1024M test.

And tweaking Spi... is an art, just look at some Team Japan' pros like Duck, Cal930 and Beetle-san :P
(also team OCX are heavy into Spi)
