Mac Pro Westmere Photoshop Performance: diglloydHuge

Last updated September 05, 2010 - Send Feedback

Please see Photoshop results for the prior Mac Pro Nehalem here and here and here.

The diglloydHuge benchmark measures core Photoshop operations, generating a huge 56GB scratch size. Even a Mac Pro with 64GB of memory will show some speed impairment.

With a hard drive, the differences shown here would be much greater; all the machines here used dual 200GB Mercury Extreme Pro RE SSDs in a 400GB RAID-0 stripe for scratch, which is as fast a scratch drive as Photoshop can utilize.

These machines are the MPG Pro Workstation and MPG Pro One (iMac); it doesn’t get any faster.
