The Dell XPS 14z comes in two Intel Sandy Bridge flavours: Core i5 and Core i7. We tested the Core i5 2430M version which performed typically well in our benchmarking tests. This powerful CPU is backed up by 6GB of memory, and even with bucketloads of programs running at once, we saw no slowdown.
Our model also packed an Nvidia GeForce GT 525M graphics card for gaming and running multimedia applications. This card is getting on a bit and we were disappointed by the stilted performance during testing. Recent games will stutter, unless you turn detail levels down to low or medium - you're better off sticking with older titles.
If you want to play the latest games, we'd recommend boosting your budget and looking at a gaming machine such as the MSI GT680 or Alienware M11x instead. The Alienware M11x is a similar weight although a lot chunkier, but more than makes up for it with fantastic all-round performance.
Although you can't smash up terrorists in high detail, you can easily run video-editing software and other multimedia applications. HD movies play perfectly too. And despite featuring some powerful components stuffed into a slender chassis, the XPS 14z remains cool and quiet at almost all times. Only when we inserted a DVD did it make any real noise.
We were also impressed by the excellent battery life, something the XPS 14z has in common with its elder brother. Usually Sandy Bridge laptops are defeated by the ruthless Battery Eater test in under three hours, but this portable played HD video on a loop for 200 minutes before finally submitting. This is almost as good as the XPS 15z's four hour longevity, and beats most other multimedia laptops we've seen lately.
