People have been speculating that this Xbench result is a bit low, maybe due to automatic settings instead of highest, or maybe because of too little RAM.

I get better results with Processor Performance set to "Highest" :

Why would an iMac have energy saving processor settings? I thought that was PowerBooks only?

Maybe for it to run cooler during times that you are not doing CPU intensive stuff? But I do find it kind of weird.

chrisutley · Sep 15, 2004, 07:56 PM

Well PowerBooks have been clocked in XBench at ~134, so the speeds leave me kind of cold.

eMac get higher then that!

gperks · Sep 15, 2004, 09:09 PM

Both with 256MB RAM.

I noticed the GPU result: 130+ FPS on the OpenGL test.

My PB 1.25GHz with a Radeon 9600 gets 62 FPS.

So the 5200 in the iMac is twice as fast as the Radeon 9600 (mobile edition I presume). That's great! I was afraid that the iMac might be a graphical step backwards compared to the PB, but these numbers indicate it is a big improvement! Great!

Nice cpu and graphics scores ... but the disk scores are pretty lousy. I got the 160gb drive BTO'd into my 1.25ghz eMac (its a 7200 rpm Seagate with 8mb cache, BTW) ... my overall disk score is ~119.0 vs 79 and 92 for these two machines.

Love to see the disk benchies on a 20" model.

That's what happens when you tilt it on its side.

So why do LaCie make external hard drives that stand on their side ?

Look, let's not get too focussed on benchmarks (especially these Xbench and Cinibench type scores). Pretty often the actual benchmarking tool isn't able to fully reflect the performance of a brand new computer model. What really counts is how the machine 'feels' doing day to day tasks. How quickly do apps load, how many can you keep open without disk swapping, how quickly does it switch between apps ? Those are the things that matter to me.

(the answers for my Powerbook 12" are : glacially, not many, slowly

)

Because they look cool and take up less space? And therefore can be vastly overpriced?

No. It doesn't mean that at all. The OpenGL test in XBench is crap. It doesn't push the GPU. I've seen low end cards get higher scores than a Radeon 9800 Pro on that the XBench OpenGL test...

If you want to see decent OpenGL tests you're better off using a real 3D benching tool or 3D games.

Keiretsu · Sep 16, 2004, 03:56 AM

Can someone explain this:

L2 Cache 512K @ 1.15 GHz

BTW compared to a PBG4 1.5 these results are pretty measly. The G5 1.8 does not even top in all CPU test categories ... for now I'm assuming Xbench sucks and not the iMac G5!

kcmac · Sep 16, 2004, 08:15 AM

I haven't done any benchmark testing but I did notice this on my iMac.

I ran iTunes Visuals at the large setting on full screen. Got about 15-20 fps.

Went into energy saver preferences and changed the performance setting from Automatic to Highest. Reran iTunes visuals at the same settings and get +60 fps.

I guess I don't understand the Automatic setting. When does the computer know when to use the highest performance setting?

Spliffdaddy · Sep 16, 2004, 08:30 AM

apparently it doesn't.
