Combined with its aluminum and carbon fiber chassis, 9mm to 15mm thickness, the system tips the scales at just 2.6 to 2.8 pounds depending on configuration. It also has an ultra thin 5.2mm bezel allowing Dell to cram a 13.3-inch panel in a smaller laptop body. The new XPS 13 sports Intel's newest Broadwell processors and an optional 3200 x 1800 touch-screen display.

A 'developer edition' of the machine will ship with Ubuntu Linux 14.04 LTS preloaded. No, they're adding one more to the list: the recently released and highly praised Dell XPS 13 refresh.

I guess better consider returning while you can and finding a laptop better suited for heavy workloads.Dell has been offering Ubuntu as an alternative to Windows on a handful of its systems over the past few years. Undervolting may help a lot (but mind Dell recently refused warranty service to someone after mentioning that he did it, although Intel XTU is public not sure if there is sth like MSI Afterburner for GPU undervolting for linux) repasting may be needed if you see direct thermal throttling within a few seconds of heavy load (with undervolt applied) padding the VRM mosfets may help. But you should monitor stuff like CPU & GPU temperatures and clocks, CPU package power, throttling flags, fan speed, and temperatures under Dell EC (first Ambient is near the VRMs), using something similar to HWinfo64. I've got no idea how this throttling works under linux and what are your workloads. It went as far as Dell reducing the GPU throttling temperature with an irreversible BIOS update, and issuing a motherboard revision with an extra VRM mosfet. There is an undisclosed throttling scheme vital for stable operation that reduces CPU and GPU clocks if the temperatures rise, but despite this some heavy users reported restarting/freezing under load in Windows initially. And in particular, the voltage regulators (VRM) lack active cooling, hence heat tends to build up in the top central area under longer workloads. Its power supply and cooling systems are undersized considering the CPU and GPU power consumption under load.
