Preliminary tests found that the 192-core System on a Chip dominates all of the off-screen "higher is better" benchmarking scores set by Tom's Hardware.
There's also a significant boost to Nvidia's Tegra K1 chip as shown by the 3DMark graphics and physics tests when compared to the Apple and Qualcomm processors.

The more fair off-screen tests weren't running off of the the device's full 3840x2160 display, although the testers did include the still-impressive on-screen performance results.
The Kepler-based GPU still muscled through the 2160p Ultra HD configuration that its less powerful competitors didn't have to contend with.
The K1-based Lenovo ThinkVision 28 is expected to launch in July, so these preliminary tests may or may not take final hardware tweaks into account.
