Today, Apple announced changes to its iMac product line, with significant upgrades in the 27-inch model, a move to SSDs in the 21.5-inch model, and more performance at lower prices for the iMac Pro.
The 27-inch iMac still has a 5K display, and its chassis is the same. Those hoping for smaller bezels will be disappointed. That said, Apple is bringing TrueTone to this display, and it's offering the same NanoTexture tech we've seen in the company's Pro Display XDR as a $500 upgrade.
It's also getting 10th generation Comet Lake CPUs across all configurations, with 6- and 8-core CPUs standard. The top available CPU configuration is a 10-core Intel Core i9 with Turbo Boost up to 5GHz. 8GB DDR4 at 2666MHz is still standard, but the maximum capacity you can configure at purchase has doubled to 128GB.
The new 27-inch iMac is equipped with AMD's new Radeon Pro 5000 series graphics. Entry-level configurations feature the Radeon Pro 5300, while the top standard config has the Radeon Pro 5500XT. There are also non-standard upgrade options for 5700 and 5700XT GPUs. The top GPU has 16GB of video memory.
Apple claims up to 55% performance gains with these GPUs, which are based on AMD's RDNA architecture and 7nm. Apple says the GPUs have faster and more power-efficient compute units than their predecessors, and the 55% figure is based on Final Cut video editing, Cinema4D rendering, and Unity game development use cases.
Also, the Fusion Drive's time in the sun has ended. The entire iMac line (including the 21.5-inch iMac, which otherwise has seen no changes today) has gone SSD storage only. Standard configurations offer 256GB or 512GB SSDs, and upgrades are available up to 8TB. Apple says these drives offer 3.4GB/s readRead More – Source
