Completely Unscientific iMac vs Mac Pro Comparison
The big debate these days is whether or not the new iMac with the Intel Core i7 can perform as a production machine.
Now I am not going to quote SPECfp or SPECint benchmark testing that indicates that the Mac Pro should handle complex tasks better – because it probably can – nor even refer to a recent MacWorld article that showed a significant bias toward the iMac but on simple single-threaded tasks.
Nope, I wanted a real world graphics test and so was privileged enough to get access to both an iMac and Mac Pro tower with CS4 for testing. I am posting these results specifically for the Graphic Artists out there who need to know how these computers will handle that really big PSD file they are working on.
We used a completely unscientific stopwatch (provided by my iPhone) and a couple of actual production files that have given us trouble due to their size and complexity. We ensured all other applications were closed and had both computers in the same room in the same networks.
Here are the results
iMac vs Mac Pro real world produciton environment tests. We loaded up these 2 computers with identical software and opened the same files hand-picked from our archives as being pain in the butt large files. Despite expert predictions of a sweep by the Mac Pro the GOLD MEDAL winner is the iMac.
Question: Why is the RAM config different?
We were advised that by installing 12 GB RAM in the tower in a specific configuration per core that it would perform better than if we installed 16 GB RAM. Again, this is not a technical article so I am not going to get into more detail. Suffice it to say the experts told us it would be no contest. They were wrong as far as CS4 was concerned.
Cost is another factor
Apple has out done themselves. The iMac while not significantly better in dealing with the Photoshop file, more than held its own with the Vector file. For me, dollar for dollar, the iMac i7 is my mid-level production machine of choice. If you have the budget and need super power you could spend more than double the cost of the iMac for the Tower alone (without monitor) before you see better results. The new towers purported to be coming out soon may change all this but for now we have what we have.
iMac Cost – Canadian Dollars $3,859
Mac Pro Tower Cost (as configured above in the chart) $4,180
Add a 24″ monitor to that = $5,179
That’s an extra $1,320 CAD for a comparable (and yes, more expandable) machine and a slightly smaller monitor. Not a huge difference but consider this: If you have 10 artists that’s $13,320 in savings and the iMacs would make useful admin machines when their production life is over – again, without having to shell out for more monitors for your admin staff if you decided to do the same with your towers.
The Mac Olympics are over and iMac wins hands down!
