Recently, the Rocket Yard tested the Late 2015 27” iMac with Retina 5K display with different memory configurations to show the huge performance gains that can be achieved with more memory. We ran a memory-intensive Diglloyd Photoshop Huge test with 8GB, 16GB, 24GB, 32GB, 48GB and 64GB OWC memory configurations and the impressive results can be found here.
But we haven’t stopped there. We put several different iMac and Mac Pro models (2009-10 Mac Pros are loaded with an OWC 240GB Accelsior E2 SSD and Sapphire HD 7950 card) to the test with OWC memory configurations up to 128GB!
Check out our new shootout page to see what we found when running memory-intensive Diglloyd Photoshop Medium and Huge tests with the different memory configurations in the different machines. The Diglloyd Medium test generates a 15.7 GB scratch file using a 20,000-pixel-wide image. And the Diglloyd Huge test generates a 56 GB scratch file using a 40,000-pixel-wide image.
The complete results (with some surprises) and winners of the shootout can be found here: https://eshop.macsales.com/shop/apple/memory/iMac-5K-Versus-Mac-Pro-Speed-Test
As you can see, it’s fairly simple: More memory = a faster Mac. And our testing shows that even “old” Mac Pros with OWC upgrades can be a performance powerhouse that rivals newer Macs. So, be sure to visit MacSales.com to find memory upgrades for nearly every Mac and more to get the best performance from your machine.
