It's also significantly faster than Vizio's CA27T-B1. That's impressive for any all-in-one, and it helped the XPS 27 Touch deliver a Desktop Worldbench 8.1 score of 262, which means it's more than two and a half times faster than our reference PC, Acer's Aspire U. Our review unit, which costs $US2100 as of July 17, 2013, sports a quad-core Intel Core i7-4770S processor 8GB of DDR3/1600 memory a discrete video card (Nvidia's GeForce GT 750M) and a roomy 2TB, 7200 rpm hard drive augmented by a 32GB mSATA SSD cache. The XPS 27 Touch packs a speedy new Haswell CPU under its hood, but that's the only significant departure from earlier models. When it comes to its high-end all-in-one PC lineup, Dell seems to be operating on the 'if it ain't broke, don't fix it' principle.
