Performance and Benchmarks
Part of the headline news with the release of the ThinkPad X220 is the use of the latest Intel “Sandy Bridge” processors. Our review unit came equipped with the Intel Core i5-2520M dual-core processor. This CPU has a standard clock speed of 2.5GHz and quickly steps up to a 3.2GHz turbo frequency whenever the notebook is performing a difficult task or running a complex application.
The new integrated graphics in the Intel Sandy Bridge platform are a noticeable step up from the previous generation of Intel integrated graphics. The X220 delivered some impressive benchmark numbers in 3DMark06 but real-world gaming tests were a combination of hit and miss since many games still won’t run on Intel graphics.
Of course, most businesses don’t care about the ThinkPad X220’s ability to play Crysis. In fact, the only thing that most potential buyers of the X220 are likely to care about is whether the notebook can handle HD video playback, video editing, and demanding Photoshop work. Can the X220 do those things? In a word, yes.
The 320GB Hitachi Travelstar Z7K320 hard drive in our review sample is extremely speedy and is quick enough for average tasks. Lenovo also offers a number of optional solid state drives (SSDs) ranging in capacities of 4GB to 160GB.
