Apple refreshes the 27-inch iMac; 21.5-inch iMac and iMac Pro upgraded too
Apple has refreshed its iMac series of all-in-one computers, although not with a new design or its in-house chipsets. Instead, the company has made some minor upgrades to the 21.5-inch iMac and the iMac Pro, along with a broader refresh of the 27-inch iMac. Starting with the first two devices, Apple has upgraded the entry-level 21.5-inch model from a 1 TB HDD to a 256 GB SSD.
By contrast, the iMac Pro can now be configured with a 10-core Intel Xeon W processor. Neither are noteworthy upgrades, which is probably why Apple included them as footnotes in its press release about the new 27-inch iMac.
While nothing has changed externally for the 27-inch iMac, Apple has applied many upgrades internally. The device now comes with 10th Gen Intel Core processors, which range from a 6-core Core i5 to a 10-core Core i9. There is now the choice between four GPUs too, which are the AMD Radeon Pro 5300, Radeon Pro 5500 XT, Radeon Pro 5700 and Radeon Pro 5700 XT. All have GDDR6 VRAM, but the volume of VRAM varies between 4 GB and 16 GB depending on the GPU.
Also, the 720p webcam has been switched for a 1080p one, which is a decent upgrade in of itself. A T2 chip has been added, as have three microphones that Apple claims are "studio quality".
The 27-inch iMac comes with 8 GB of DDR4-2666 RAM and a 256 GB SSD by default, but you can configure it up to 128 GB of the former and 8 TB of the latter should you wish to do so. Additionally, Apple offers a US$500 upgrade for nano-texture glass and a US$100 upgrade for 10 Gigabit Ethernet. The 27-inch iMac starts at US$1,799, but it can be configured up to US$8,428.
