Dell Studio 1557 review

Price when reviewed

When we first caught sight of Intel’s mobile Core i7 we were unashamedly excited. Finally, the prospect of serious quad-core power lay within tantalising reach of the mobile market, and without the heinously bad battery life of the previous Core 2 Quad generation. The one thing we didn’t expect, was for it to find a home in a laptop costing just £653 exc VAT.

Indeed, it wasn’t so very long ago that we took a close look at Dell’s previous model, the Studio 1555. A decidedly mid-range desktop replacement, the 1555 employed a 2.4GHz Core 2 Duo processor, ATI Mobility Radeon HD 4570 graphics, 4GB of DDR2 memory and a 320GB hard disk, and all for a total cost of £609. Very reasonable, you might think. Now, however, Dell has gone one step further. Everything else stays much as it was, including the price, but that Core 2 Duo now finds itself brushed aside by the entry-level model in the Core i7 range, the Core i7-720QM.


Describing the i7-720QM as entry-level, though, is akin to calling Lewis Hamilton a trumped up go-kart racer. Its four processing cores may all operate at a modest-sounding 1.6GHz, but it’s capable of ramping up its clockspeed as far as 2.8GHz when the occasion demands it.

And it’s entirely thanks to the presence of Intel’s Core i7 that, despite weighing a reasonable 2.65kg, the Studio 15 finds itself transformed into a true performance heavyweight. That 4GB of memory is now of the faster DDR3 variety, and allied with a fast 7,200rpm hard disk the Studio demolished our benchmarks with a staggeringly quick overall score of 1.59.

And while the relatively compact chassis precludes the inclusion of a really powerful graphics chipset, the ATI Mobility Radeon HD 4570 finds a supremely able partner in the Core i7. Our least-demanding Crysis test cruised to a result of 56fps, and while upping the ante to medium detail saw it struggle to an average of 15fps, it’s worth restating that Crysis is as demanding as games get. For a mid-range laptop, the Studio is preternaturally able.


It’s not a bad looking laptop either. The chunky wedge design looks smart and presentable in its combination of black and graphite grey, and only the overly pliant lid gave us any real cause for concern. And should the black chainlink finish prove too plain for your tastes, a premium of £89 will buy you one of several “arty” designs.

Meanwhile, the glossy 15.6in display has a standard 1,366 x 768 resolution, but to make full use of the power at the Studio 15’s disposal, we’d be tempted to pay the extra £70 to upgrade to the optional Full HD panel. Even if you don’t, though, image quality is excellent, with vibrant, accurate colours, strong contrast and believable skintones.
