To give a general, overall score of the XPS 13’s performance, I ran PCMark 8’s ‘Home Conventional’ test.
The fastest score I have seen since beginning to use the PCMark 8 benchmark, the XPS 13 is over 100 points ahead of the BRIX.
To test the memory bandwidth of the 8GB DDR3L RAM that comes with the XPS 13, I ran SiSoft Sandra’s memory bandwidth benchmark.
Performance is limited here by the use of older, DDR3L memory instead of the newer DDR4 standard. Most users will not notice this on a day-to-day basis, however, and 8GB is a decent capacity for an Ultrabook.
