Super Pi Question

[fishboi]

Guys,

I've never run Super PI before, and am not familiar with the program. How do I know what to bench my result against (see below)? Is this good or bad?

Thanks!

To give you some scale on the 1M calculation
E6700 1M is about 20-21 seconds
E6800 1M is about 18-19 seconds
P4 3.6 GHz is about 41-42 seconds
AMD FX-62 is about 33-35 seconds

I'll add to that list

AMD Athlonxp 2500+ 1m is about 49-51 seconds :tongue:

Semi random: Anyone know where I can find the C++ source code for SuperPi or similar programs?

 

[fishboi]

Guys,

I got 16 seconds for the 1M calc. This seems good no?

 

[tool_462]

Very good time. With my D805 @ 4.0Ghz I think I run 31 seconds.

 

[fishboi]

Cool. Thanks.

 

[fishboi]

Cool. Thanks.

I ran 1M Super Pi in 21s.

Nothing overclocked, E6600/2GB DDR2-667.

Is Super_PI really a good benchmark though?

I've seen so many different results... makes my head spin. :?

Like for example, my P4 3.0/800 gets around 50 secs, yet I've seen others get 40-46 secs.

My dad's poor old Amd XP2400+ does around 1min 10 secs, and I've seen scores of 40-49 secs.

16 sec in Super Pi (1m) is fairly acurate. Iam getting 15.375sec at 3.03ghz with my c2d e6600.

Iam using a Super Pi mod 1.5 which gives you fairly acurate readings in sec and milli sec and so on.
Here is an website to download the mod 1.5

Here is my shot at 15.375 sec in 1m.

Well for me, Super PI and other benchmarks are only intended to give you an idea of the relative performance of the CPU. Some may jump up and down a few steps depending on the task at hand. But usually the jump is realtively small, though this may be false with processors that simply have a different design. Such as memory access times between certain Pentium D dual-core vs Athlon FX. The Pentium D may be faster at video encoding but due to the FX's design, it is better at memory access and jobs such as mp3 encoding. (I am only talking about the highest end of the Pentium D)


Benchmarks usually just give you an idea. There is no absolute way to test how well a processor performs, since you also have to take into account its sorroundings (mobo, ram, hdisk, etc). Though a ton of money would surely get you the fastest pc in town.

Heh, feeling abit tired, so I'm not sure if my question on Super_PI was clear.

So I guess what I was asking, in comparing a P4 3.0/800 system to another P4 3.0/800 or another P4 system OC to 3.0, and getting different time results, just puts a question in my mind in how that can be? Especially when its a CPU test based on computational power?

As well as comparing AthlonXP 2400+ to another AthlonXP 2400+ like I mention the different times I saw for it to complete 1M.

Just seeing lower timings based on the same CPU, I just don't seem to understand why that is.

 

[pshrk]

P4 3.6 GHz is about 41-42 seconds

Really? Wow! I got my Prescott 3.2GHz with an OC to 3.5GHz to get 1M in less than 40 seconds. not bad for an OC n00b. I think i could do a lot better if I had better memory. You just made my day! 😀

E6600, 2gb XMS6400C5, ASUS P5B Deluxe Wifi

Stock SuperPi = 20 seconds

At 400x8 (3200) i get 15 seconds on stock cooling

My times seem a little better?

 

[shinigamiX]

I think you're missing the point - the real benchmark is not SuperPi, it's a SuperPIE - to the FACE!

I like your avatar

Thats one of my favorite skits of theirs. lol!

SuperPi isn't just a CPU computational test, though primarily it is. It exercises the cache subsystem and a little bit of main RAM - whatever is necessary to figure out Pi to several million digits. Because the XS mod version reports to such precision, even at 1M you'll see performance differences merely by adjusting FSB, RAM timings, background processes, even hard disk file system and fragmentation. But these latter factors won't have nearly the effect of a gross overclock to the CPU.

I'd run SuperPI on my 1.7GHZ Pentium-M, but I don't want it to be calculating PI for the next couple of hours =P

Really need to upgrade...

 

[fishboi]

Does your RAM affect SuperPi in any way? (ie. frequency, timings, size etc)

 

[dasickninja]

I believe yes.

 

[Doughbuy]

Marginally thought, some review sites use SuperPI to test RAM, but like its been said, these are all small things compared to sheer processor power.

 

[fishboi]

Maybe you guys can help. Check my specs on the sig. I need a benchmark program to measure my RAM speed/effectiveness. I changed my RAM out of the 1:1 divider (370 FSB, should be DDR740), but I used the 4:5 divider and made it 925Mhz.

I had to loosen my timings to 5-5-5-15 from 4-4-4-12.

I ran 3DMark06 and PCMark05. The results were worse (but just by very little).

Are there better programs to measure whether I should go with tighter timings or higher frequency?

PS. I used Sandra lite, and the mem bandwith was much better. Not sure how to interpret all this though. THANKS!

 

[dasickninja]

What speed RAM are you running?

 

[Doughbuy]

OCZ Plat Rev 2 sounds like DDR2 800 to me...
