An Xlr8yourmac reader email describes some OS X Benchmarking apps from Apple:

What I thought might interest your readers is the bashpack.dmg that is installed in Developer/Applications. This disk image contains a suite of four benchmarking applications; CacheBasher for testing cache/memory bandwidth, DiskBasher for testing drive performance, GraphicsBasher for testing Quickdraw performance and Skidmarks GT for basic processor performance.

The application is available from Apple - use at your own risk.

Of note, Apple had reposted a final version of their Taking Apart Your iMac service document... but it has since been pulled off their site. Fortunately, a quick Google search reveals other sources (albeit Draft versions) of the same... for those who are intent on opening your iMac.

This stuff is really confusing, but I'm going to try it tonight. I think I'm just going to do the Skidmark test because all those numbers from the other tests dont mean anything to me.

Every link I've found so far has been for the DRAFT version of the document.

Where is the FINAL version that was reported on?

Thanks :)

DUAL PROCESSOR 533 w/768mb ram! Shouldn't my results be a little higher than an iBook 600?

-Pete

Do I have my settings wrong? Is it not seeing my second processor?

On my G3 233...

...I get

Int: 599
Float: 480 (roughly, I'm typing from memory)
Vector: N/A


btw, the iBook 600 scoring higher on int and float than a G4 533 is to be expected. The speed gain of the 533 comes from the other processor and the vector math (the G4 got 1300 on vector, the iBook got N/A because it doesn't have Altivec). I *think* that the DP533 scoring lower than an iBook 600 shows that it only tests one processor, but I could be wrong. Try setting the number of threads up to two.

Also, the G4's more advanced FP unit gave it a higher float score, while its lower clock speed gave it a worse integer score.


For cachebasher it shows this (I think)
1st column: size of the data being transferred
2nd column: something
3rd column: number of bus clock cycles it took
4th column: number of clock cycles it took
5th column: bandwidth (available bandwidth? used bandwidth?)


The ratio of the third column to the fourth shows your bus multiplier. On mine the 4th column was always 3.5 times more than the third (66*3.5 is roughly 233). On a DP1GHz it would be 7.5 (if I remember correctly). On a 2GHz P4 (if you could run the benchmark on a P4) it would be 5. It really shows how slow busses eat up processor clock cycles.

Actually, PT, the scores are very accurate. My iBook is 77 MHZ faster than your Dual 533. That would explain the INT. score being higher. You have a better floating point unit, and you have the vector Unit :( wish I did. This little iBook is reall quick and I love it, but with multi proc aware apps, and with OSX supporting Multi proc, you have got to love your system.

This is either the fastest iBook ever, or it is somehow been sent through time, and came back with a G7 :p

Don't know how it happened, but I thought my brothers would like a good laugh.
Gotta love those bugs that give you crazy scores like that!

Here's my scores on my G3 450 @ work:
Integer: 1127
Floating Point: 952
Vector: N/A

Uh, i guess my iBook is pretty darn fast. This was the first time I ran it. The second time results were:

Integer: 1511
Floating Point: 1274
Vector: N/A

Some more info on Skidmarks

Everybody seems really excited to use Skidmarks, but before it 's results are misinterpreted I would like to point out a couple of things:

1) it is a processor benchmark pure and simple - no system level stuff at all. As such it tends to scale linearly with processor frequency.

2) it does not take advantage of dual processors at this time

<whew> That calms my nerves a little bit. My 533 still isn't nearly as fast as the Dual 1gig would be, but it must wipe the floor with a single G4 400. (no offense to G4 400 owners)
