IMacs and MacBook Pros take a dip in Kaby Lake

The 27-inched variant of the iMac (2017) gets Radeon Pro 570, 575 and 580 GPUs.

Much like the new updated iMac models, the new MacBook, MacBook Pro and MacBook Air will be available to order starting Monday via, and will go on sale via Stores starting on Wednesday. The iMac Retina 4K 21.5- inch will now be available with AMD Radeon discrete graphics, with your choice of Radeon Pro 555 and 560 graphics cards and up to 4GB of dedicated VRAM. Even on those 21-inch models without Fusion Drives, storage is getting larger and faster, with up to 2TB of solid-state drive storage. Featuring a new next-generation compute core and up to 16GB of on-package high-bandwidth memory (HBM2), iMac Pro with the Vega GPU delivers up to an 11 Teraflops of single-precision compute power for real-time 3D rendering and immersive, high frame rate VR. The new iMac (2017) comes out with "the best Mac display ever".

The iMac Pro comes with the new AMD Radeon Pro Vega GPU.

Apple said that the new iMac display is 43% brighter at 500 nits and with support for 1 billion colors. New iMacs will come with two Thunderbolt 3 ports instead of Thunderbolt 2, and Apple further claims the SSDs in these machines will be 50% faster than those in its outgoing all-in-ones.

We compare Apple's new iMac Pro desktop computer with the original 27-inch iMac, to see what the difference is in terms of specs, graphics, price and other key features. "Apple announced that it's partnering with Valve to bring the SteamVR SDK to the Mac, and the new graphics options for the 27" version offer the hardware foundation required to power VR headsets for folks who prefer to create VR experiences in macOS.

The updated iMac features faster Kaby Lake processors up to 4.2 GHz with Turbo Boost up to 4.5 GHz and supports up to twice the memory as the previous generation.

The updates are definitely welcome, especially on the MacBook Pro front, so if you've been waiting to snag a new Mac for months, now might be the time.

iMac Pro is scheduled to ship in December starting at $4,999 (US). The all-in-one will be capable of connecting to "up to two high-performance RAID arrays and two 5K displays at the same time". SSD storage options are now up to 50% faster. "We reengineered the whole system and designed an entirely new thermal architecture to pack extraordinary performance into the elegant, quiet iMac enclosure our customers love - iMac Pro is a huge step forward and there's never been anything like it".
