New versions of the Mac OS need a base MINIMUM RAM of 8 GBs, now. The 2012-2015 baseline 21 inch screen iMac models only come with 8 GBs of RAM standard.
INTERNAL HARD DRIVE FOR IMAC INSTALL
This would not be as big an issue if you could install more than 16 GBs (which there is no way to do this in these 2013-2015, 21 inch screen iMacs as Apple has soldered every single component to the logic board). The GPU will automatically steal whatever the amount of physical RAM the the GPU needs for any type GPU related task. Meaning that the GPUs in these newer 21 inch screen model iMacs is stealing away physical RAM, for use by the GPU, for the GPU's VRAM, that could be needed for any other possible RAM intensive tasks depending on the apps being used or what combination of apps is being used together. Meaning that in any of the newer 21 inch screen model iMacs, if you get one with the max 16 GBs of RAM, a little bit to quite a bit of that installed RAM is being used for the GPU's VRAM! These older slimline 21 inch screen iMacs use the "so-called" integrated (soldered) Intel Iris ”Pro" GPUs, now! This means up to 50 % slower read/writes to the drive, in addition to other system delays.Īlso, like laptop models, these older 2013-2015, 21 inch screen iMacs no longer use dedicated, discreet and independent GPU chips. Slower 5400 RPM laptop standard/style hard drives are 33%-50% slower than the equivalent storage size in a "desktop standard" 7200 RPM hard drive. These 2012-2015 slimline 21 inch screen iMacs are limited to just 16 GBs of RAM.

Slower laptop standard 5400 RPM, 2.5 inch hard drive/fusion drives, limited RAM (the 2010, 2011 i5 CPU models and higher could take up to 32 GBs of RAM). There is nothing in the 2013-2015, 21 inch screen iMacs the is user upgradeable OR serviceable, any longer.
INTERNAL HARD DRIVE FOR IMAC PROFESSIONAL
The 2013-2015 slim profile, "slimline", 21 inch screen model iMac are, basically, sealed up, glued up, basic computing appliances, now, with only the "top of the line" with all the top options (top i7 CPU, 16 GBs of RAM, 256 or 512 SSD) being the only viable option to use as a standard to medium professional grade, work related, iMac with just enough power for professional and creative use. The 2013-2015 slim profile 21 inch screen iMacs that Apple had offered are, IMSO, "downgrades" from the previous 2009 thru 2011 21 inch iMacs models. Here are the BIG issues with all, but the topped out, 2013-2015, slimline, 21 inch screen iMacs.
