Is this the 32M you're calculating?

I really expected more from my comp.

36m 56.157s

P4 641 Prescot @ 3.2 ghz w/ 1 gig DDR2 mem.

SuperPI says only 268 meg mem is allocated though. Might try running it again later on a fresh reboot. I had multiple windows open and was still browsing and working while it ran.

---

32M? nope - just run the 1M test, that's usually quick (well, most folks here are around a minute) - 17 seconds is pretty darned fast

---

I missed where you said that in the original post. In that case, I get 42.250s. I feel MUCH better now! I still think I can do better on a fresh boot.

**EDIT** Fresh reboot and killing off some background programs netted a tiny speed boost. Got me down to 41.781s Nothing close to your crazy 17 second run, but better than every AMD that's run it so far. Guitarman's AMD 64 3400 has been the closest.

Faster than my P4 3.4 machine. Go figure...?

First of all, it is not fair to compare my two systems. The AMD was a mid-speed computer in 2000/2001, however, you can compare them to similar systems.

First up, my laptop with the following important specs:

1.6GHz Pentium M w/2MB L2 cache overclocked to 2.13GHz via pinmod

2,048MB (2GB) of PC4200 DDR2 RAM

533MHz FSB

Now my desktop:

1.4GHz Athlon Thunderbird (last of the non PR rated CPUs)

1,024MB (1GB) of PC3200 DDR RAM

266MHz FSB

You can compare the results of each to the following setups:

Laptop:

Supposedly a ~2.0GHz Pentium M is faster than a 3.2GHz Pentium 4 with HT disabled. So you could compare this to an Athlon that is PR rated at "3200" I suppose.

Desktop:

The first PR rated Athlons was the Athlon XP "1800" 1.5GHz. So I suppose you could compare my 1.4GHz T-bird to a 1.7GHz Pentium 4.

Oh, and I forgot to mention, supposedly Pentium Ms are horrible with floating point calculations, so I had better see some Athlon "3200"s beating my laptop!

---

no need to run the 32M test (unless you want to wait for it) - just try the 1M test, that's usually the standard size

you can also try PiFAST - it's much MUCH faster - i can calculate 1,000,000 iterations in 1.43seconds

Not mine!

TourDeForce - did you have a lot of applications and processes running when you tried? I still had 32 processes running, but no applications, and hit 41.781s. Mine is a P4 3.2, I'd think you could do better than a 49s+ time.
