Powermac G3 more RAM efficient than MacBook Pro?

I have a question that I hope someone here can answer for me. I have a 1.86GHz MacBook Pro and a 450MHz Powermac G3 B&W. Each computer is running Mac OS 10.4.9 and each computer has 768Mb of RAM. Here is the problem. For some strange reason the G3 seems to be more efficient when using its RAM. I checked Activity Monitor immediately after each machine started up with ONLY the Finder running. Somehow the G3 manages to keep 574.48Mb free when the MBP can only keep 497.12Mb free. 270 is used on the MacBook Pro, whereas the G3 is only using 193. Can anyone explain why the new Intel Mac is running out of RAM first?

The G3 actually appears to have more running than the MBP. I got screenshots of both but it doesn't look like you can upload them here anymore.

Have you checked the swap usa

Have you checked the swap usage? It's not a good comparision until you check the total memory usage, not just the free RAM.

My mini has 1GB and 10.4.9:
PhysMem: 91.8M wired, 235M active, 464M inactive, 790M used, 233M free
VM: 3.42G + 139M 176447(0) pageins, 4556(0) pageouts

And it's been up nearly 25 days, since I installed the 10.4.9 update.
