Dell Inspiron 14z review

Price when reviewed

That sturdy build pays dividends elsewhere. We weren’t impressed with the keyboards on Dell’s recent Inspiron series, but the 14z is much better. There’s none of the flex of those models here. Its Scrabble-tile keys are all segregated by nice wide channels and feel positive under the finger. The multitouch touchpad worked well, too, although we weren’t too keen on its overly stiff buttons.

It is possible to build the Inspiron 14z to a tight budget. In fact, you can go as low as a 2.1GHz Intel Core i3-2310M processor. Our model (E-Value code: N00NZ421) came with the fastest available CPU in the range, and in our benchmarks, the Core i5-2430M and 4GB of RAM delivered a result of 0.66 – more than fast enough for most needs.

The absence of dedicated graphics makes for modest gaming performance, but the GPU built into Intel’s Core i5 CPU is far from useless: an average frame rate of 29fps in our Low quality Crysis test proves that there’s enough grunt for light gaming.

Dell Inspiron 14z - front

The Inspiron 14z isn’t just quick, however. Thanks to the six-cell battery at the rear, that Core i5 performance comes with serious reserves of stamina. It lasted 8hrs 36mins in our light-use test before finally limping back to the mains socket.

The Dell’s glossy 14in 1,366 x 768 display is the only major let-down. Colour reproduction is reasonably accurate, if a little pale, and the Inspiron 14z’s panel made a good fist of our test images. It isn’t perfect, however, with greyish blacks robbing images of solidity and depth, and blotting out detail in darker scenes. Our X-Rite colorimeter proved as much. The backlight peaks at a dim 203cd/m[sup]2[/sup] – significantly lower than we’d expect – and the contrast ratio of 195:1 is mediocre.

It might not set the world on fire, but the latest addition to the Dell Inspiron range still has much to offer. Good build quality matches up with speed and stamina, and if you can find it in your heart to overlook that not-too-impressive screen, the 14z is a bit of a bargain. If you’re looking for power and portability on the cheap, it might be just the ticket.
