Reviews for the Dell Studio 1557
Processor Giant. Slowly, Intel's brand new processor generation Core i7 is also advancing into current notebook series, and promises more performance with the same power consumption. The for some time already available Dell Studio 15 has now found its way to us with an Intel Core i7 Q720 CPU and has to prove just how much it can benefit from the new little computing power station in the following test

Stunning quad-core power at a great price, but mobility is inevitably flawed. Dell's Studio 15 greatly impressed us last year by combining power, usability and features at a truly affordable price, and even won our award for best laptop of 2009. Building on its already strong foundation, the Studio 1557 makes stunning quadcore performance truly accessible to the consumer market. While the restrictions it places on mobility are unfortunate, they were inevitable and do little to flaw this impressive portable.

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. Dell’s Studio 15 brings Intel’s mobile Core i7 into the realms of affordability, offering quad-core power for substantially less than £1,000.

Comment
ATI Mobility Radeon HD 4570: Lower middle-class GPU that features a low shader count and a 64 Bit memory bus but a high clock speed. Similar to the desktop Radeon 4550. Supports Avivo HD and DirectX 10.1.
Non demanding games should be playable with these graphics cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
720QM: The Core i7-720QM is the slowes Core i7 Quad Core in 2009 and clocks between 1.6 and 2.8 GHz (due to the Turbo Mode). Therefore, it combines the advantages of a slow quad core CPU with a fast single core one. Compared to the faster Core i7 mobile CPUs, the 720QM only features 6MB L3 Cache.» Further information can be found in our Comparison of Mobile Processsors.
15.6": 15 inch display-variants are the standard and are used for more than the half of all notebooks. 15.4 inch display with 16:10 are the standard for notebook displays. However nowadays, more and more 16:9 displays with 15.6 inch appear. The reason why so many people like displays with medium size is, that this size is not exhausting for the eyes, does not need too much energy and the laptops can be kept quite compact.» To find out how fine a display is, see our DPI List.
2.6 kg: This notebook is lighter than the average of all notebooks. It is too heavy for sub-notebooks. 14 inch displays are normal for this class of weight.
Dell: Dell Inc. is a multinational technology corporation that develops, manufactures, sells, and supports personal computers and other computer-related products. Based in Texas, Dell employs more than 82,700 people worldwide (2009). In 2006, Dell purchased the computer hardware manufacturer Alienware. In most countries, the laptops are directly sold to consumers by Dell and each notebook custom-assembled according to a selection of options. Market share regarding sales of personal computers in 2007 (market research IDC): HP 18.9 %, Dell 16.4 %, Acer 9.9 %, Lenovo 7.5 %, Apple 5.7 %
84.2%: This rating should be considered to be average. This is because the proportion of notebooks which have a higher rating is approximately equal to the proportion which have a lower rating.
