CPU and GPU Performance
Here's what you've been waiting for, performance benchmarks. As you might have guessed, XMG's P303 Pro is no slouch. Even when configured with the Core i7-4702MQ - technically the slowest available chip option - it delivers a level of multi-core performance that's exceptional for a 13.3in machine.
Laptops rarely score in excess of 5,000 PCMarks, but XMG appears to be developing an exception to that rule. This benchmark examines multiple facets of system performance, taking into account the storage subsystem, media encoding and everyday tasks such as web browsing. The results are quite clear, with the P303 Pro delivering the sort of performance you'd expect from a bigger machine.
The Haswell CPU delivers, but what about the accompanying Nvidia GeForce GTX 765M GPU?

A quick look at the comparison table tells us that Nvidia's mobile part has plenty in common with the desktop GeForce GTX 650 Ti Boost. The mobile variant admittedly operates at a lower frequency, but we should still see strong gaming performance. Question is, is the GPU enough to drive today's games at XMG's native 1,920x1,080 resolution?
XMG's P503 Pro came equipped with a GTX 770M GPU, the P303 Pro's GTX 765M sees performance drop by nearly 20 per cent, yet this is still the best 3DMark result we've recorded from a 13.3in machine.
