At the Sundance Film Festival this week, Dell refreshed its Precision M3800 15-inch workstation with a new option of an Ultra HD (3840×2160) 10-finger multi-touch display, the addition of a Thunderbolt 2 port, and the ability to configure the system with up to 2 TB of internal storage.

Also new from the M3800 is the option to get a developer edition of the machine with Ubuntu installed, rather than Windows 7 or 8.1. One catch—the Ubuntu version won't support Thunderbolt at launch, though the port is expected to be enabled by this spring.

The Thunderbolt 2/miniDisplayPort replaces the plain miniDisplayPort on the left-hand side of the system, while one of the original M3800's three USB 3.0 ports has been removed in the bargain. The new M3800 has two USB 3.0 ports and one USB 2.0.

The system has a starting weight of 4.15 lbs. and is less than 0.71 inches thick. Like its predecessor, it's powered by an Intel Core i7 quad-core mobile processor and Nvidia Quadro K1100M graphics.

Dell also trumpeted the results of a study it commissioned that it said showed its system outperforming a similarly configured MacBook Pro with Retina display when transcoding, rendering, and playing back in Adobe Premiere Pro CC.

Starting price for the M3800 at Dell's website is currently $1,649. For more on the Dell Precision M3800, see Studio's complete review from last summer.
