Just %: numbers below 100% are a loss in performance

Interesting. Not quite the 4x improvement that apple advertises, but not bad at all! Question: are any of the MacBookPro affected by Rosetta emulation?

Sorry but those tests cannot be considered as done in correct conditions as the RAM size and the HDD are not the same on the two machines (they may have even different RPM).

Everybody knows that MacOSX is RAM hungry and putting twice on the old machine gives maybe more "juice" to it.

Last but not the least, EVERYBODY is waiting for the real battery life results. That's the most important info we are all waiting for.

I'm confused Erik, how come your PB G4 1.25 significantly outperforms a PB G4 1.5? Is it the same test?

Looks like Quartz is NOT optimized for Intel yet. From what I've read other places, I guess I should be surprised it even runs. The lines that surprise me most are "Copy 9.81 105.57" and "vecLib FFT 85.16 38.17". Both of them seem very weirdly skewed...in opposite directions. But I don't even know what they mean.

Other than that, it looks safe to say that the machine is generally about twice as fast, which should result in a noticeable improvement in speed during use. Is this the case?

Actually I agree with Charles the numbers do look a little low on the Powerbook G4 1.5Ghz.

My PB G4 1.67 Ghz comes out 63.19 on the CPU test and 43.8 overall.

Ralph, MacBench 1.2 has a 100 point baseline to a dual 2.0 GHz G5 running Tiger, so the numbers in each column represent a percentage as compared to the dual 2 GHz PowerMac

My CPU Test yielded 69.15 overall (139.69 GCD, 46.48 FP Basic, 98.27 FFT and 52.65 FP Lib) - 1.67Ghz Powerbook.

Compared to above as 100%, the MBP has the following:

Overall: 97%
GCD: 172%
FP Basic: 153%
FFT: 39%
FPLib: 126%

There is a bug in Xbench when running on Intel. You need to Turn off the Beam sync option within the Quart Debug application found on the developer tools).

Here are the correct MacBook Pro results:

here is the result for my PB G4 1.25 with 512MB RAM i am suprized that the overall result is higher than 1.5 Ghz !!!!!!

The MacBook Pro has half the RAM of your Powerbook!

As one of the other people pointed out, that is a big deal!!!!!!!

To the photoshop guy - O'grady has a basic benchmark of Photoshop at http://www.powerpage.org/archives/2006/02/the_apple_core_macbook_pro_photoshop_benchmarks.html

Basically the performance of Photoshop on his 2 tests falls roughly half way between a TiBook 1Ghz and a PowerBook 1.5Ghz... closer to the PB than TiB.

He links to the ZDNet article he published - I'd give you that but this whole "no free link advertising" got me worried (and the "Terms" don't come up when I click 'terms'!)

Hope that helps!

Here's what I got on my PB 1.67.
