Apple has previewed the new iMac Pro ahead of its release later this year. Apple calls this machine its ‘most powerful Mac ever’ and includes a space gray casing.

That description means the new all-in-one machine will rival the current Mac Pro which will be replaced with a modular version in the future.

The new iMac Pro will feature four Thunderbolt 3 ports with support for up to two 5K displays, a 1080p FaceTime camera, realtime 3D rendering, and much more. Other specs start at a 5K built-in display, 8-core Xeon processors, Radeon Vega graphics, 32GB ECC memory, and 10GB Ethernet.

The new iMac Pro will start at $4999 and be available in December.
