Of course, you can always add as much RAM as you need, so you can upgrade the base 8GB to 16GB, 32GB or, 64GB as well. As I noted in my 2020 iMac RAM memory upgrade tutorial, it’s possible to purchase 128GB of RAM from a third party and easily save lots of money compared to what Apple charges. This time around, Apple specifically markets the ability to upgrade to 128GB during build-to-order configuration.īut here’s a suggestion: Don’t pay Apple for a 27-inch iMac memory upgrade. That’s not a lot of memory, but there’s a total of four SO-DIMM slots in the iMac that allows you to configure additional memory above the base 8GB.Īlthough the 2019 iMac could technically support up to 128GB of RAM, such capability was never advertised in Apple support or marketing materials. The base model $1,799 iMac comes with 8GB of RAM across two 4GB 2666MHz DDR4 memory modules.

Having two extra ports and an extra Thunderbolt 3 bus for them to share would have made a big difference for professional workflows. It’s unfortunate that the iMac continues to forgo the extra two Thunderbolt 3 ports found on machines like the Mac mini, iMac Pro, and MacBook Pro. You’ll find the following I/O options on the rear of the 2020 iMac: UHS-II SD Card support, on the other hand, is standard. Like the Mac mini, the 2020 iMac presents 10GbE connectivity as a $100 build-to-order option instead of a standard feature like it is on the iMac Pro and Mac Pro.
All of the ports remain the same except for the availability of 10-gigabit Ethernet, and a UHS-II SD Card reader. In other words, if you strongly dislike the way the iMac looks, with its sizable bezels and chin, then it may be worth waiting for the upcoming redesign.Īnother thing that hasn’t really changed is the port selection.
