My Apple Mac Pro vs. G5 PowerPC
Tuesday, October 5, 2010 at 5:47PM 
I recently purchased the Apple Mac Pro with the 4-core processor. I went with the slightly upgraded 3.2GHz Intel Xeon W3565 vs. the base 2.8GHz. I really wanted the 6-core, but with a $1200 upgrade price, I decided I could wait and upgrade later when prices of processors go down. Other World Computing (macsales.com) offers a nice upgrade path where you send them your processor tray, and they ship it back with any processor you desire.
I’ve had the G5 for over 5 years and it was starting to show it’s age. The HD era has had me screaming for more horsepower for a while, and not being able to upgrade to the latest operating system was frustrating to say the least.
Well if you are a geek like me, then you will appreciate the Geekbench test numbers.. My G5 dual processor 2.3GHz managed a Geekbench score of 2085, and my new Mac Pro managed a score of, wait for it… 10116
That measures processor/memory performance which makes my new one 4.8 times faster…nice!
I ran a few tests on both machines and I’m happy with my choice. With the Mac Pro included memory of 3GB, and my G5 PowerPC having 4.5GB. All times below are in minutes:seconds.
VisualHub converting a mpeg-4 clip to iPod sized file took 16:40 and 03:12 on the Mac Pro. That’s a difference of over 13 minutes.
When importing 80 RAW files into Aperture, wich I do a lot of, the times were 05:51 and 02:39 on the Mac Pro, a difference of just over 3 minutes. That adds up fast when you process thousands of images.
Exporting an iMovie file(42min long) to iPod version, took 37:19 vs. 13:51 on the Mac Pro.
Those comparisons were with the stock memory (3GB) on the Mac Pro, and 4.5GB of much slower memory on the “old” G5. I expected my new one to be much faster, and I’m not disappointed.
Here is what Apple says about memory in the new Mac Pro’s:
Install more memory in your Mac Pro in a snap. Literally. The easy-access interior lets you slide out the processor tray in one smooth motion, then simply snap new memory into place. You don’t have to dig around inside the computer or wrestle with wires or cables. The single-processor Mac Pro offers four slots that support up to 16GB of DDR3 ECC SDRAM, while the dual-processor Mac Pro offers eight slots that support up to 32GB.
I have installed 24GB into my single-processor Mac Pro without any problems, and I have one slot still open. I purchased the 8GB modules from OWC (macsales.com) which they had reported worked in these machines without a hitch.
