How fast can you computer calculate 1 million digits of PI

[bacterio]

with PIFast 1M takes only 3.95 seconds on a Intel P4e at 3'2ghz!!

Hmm 2.28 Secs on my AMD64 3000+

I dont know why but Super PI is the choice of many overclockers to test the performance increase from a overclock. Also you cant compare results from PI fast to Super PI.

SuperPI 1M took my 3.6GHz p4 28 seconds, overclocked on air ofcourse.

Duration : 6.81 seconds for pifast on a XP1800

Some one must have a slow-ass computer kicking around they can test it on!

I can get access to my 450mhz P3 and 450mhz K6-2 on Sunday/Monday and get some results... Perhaps you want something slower?

[sammyc]

Will still be interesting to see the diference on that machine.

Sounds like I need to get my test systems set up - I could test on anything from 386 up (dependant of course what is the oldest OS, and hence system, that SpuerPI or pifast will run on...) if I had my work area organised and not cluttered up with loads of computer remains

I doubt it'll run on anything older - I would test on a 286 with DOS if I thought it would work (that's one that I think I can get set up without moving a room full of boards and boxes around), but I suspect that such a benchmarking app will only work with a bloatware OS installed.

From the help file it says that you can run Super PI on Win 3.1 with win32's installed.

So maybe a 286 with Windows 3.1 in real mode lol?

[debs3759]

I thought about my 286 system because a 286 can run pmode code, just not 32-bit I guess there might be a tweak to enable emulation of 32-bit code on a 16-bit system, but that would really slow things down May get 1k places in an hour

Debs, can u knock up a similar universal programme with your skills? CPU-World exclusive that we can use here for world records?
