In a world full of sleek and slim Ultrabooks, the Dell Inspiron 15R 7520 looks enormous. This 15.6-inch laptop is bulky, heavy (7.4 pounds), and not terribly stylish. But it does have some surprises under the hood—namely, four USB 3.0 ports, a full HD screen, and solid overall performance.
Our review model, which costs $1100, sports a third-generation Intel Core i7-3612QM CPU, 8GB of RAM, and a 1TB hard drive spinning at 5400 rpm. It also features an AMD Radeon HD 7730M discrete graphics card, built-in Bluetooth 4.0 and Wi-Fi 802.11n, and a Blu-ray Disc player. The Inspiron 15R 7520 runs the 64-bit version of Windows 7 Home Premium.
Performance
In PCWorld's WorldBench 7 benchmark tests, the Inspiron 15R 7520 did well, earning a score of 137. This score means that the Inspiron 15R 7520 was 37 percent faster than our standard testing model, which carries a second-generation Intel Core i5 desktop processor and 8GB of RAM. Although 137 is a good score for the all-purpose laptops category, it isn't excellent: For example, the Alienware M14x, an all-purpose laptop designed for gamers, posted a mark of 143 on WorldBench 7.
The Inspiron 15R 7520 performed very well on individual tests. First of all, it had a startup time of 22.3 seconds, which is quick for a non-Ultrabook laptop; by comparison, the HP Envy Sleekbook 6z-1000 took twice as long (45.9 seconds) to start up. The Inspiron 15R 7520 also did well in our Web performance and office productivity tests, producing 13.5 frames per second in the former and achieving a score of 4218 in the latter.
