Lenovo ThinkPad X1 Ultralight Laptop Review
Test Systems, SiSoft Sandra
Our test systems all launched relatively recently, and both are targeted at the lightweight, ultra-mobile market. The x120e uses AMD's new Fusion platform, while the U260 uses a last-generation Core i5 with an 18W TDP, as opposed to the 35W processor inside the ThinkPad X1.

We continued our testing with SiSoftware's SANDRA 2011, the System ANalyzer, Diagnostic and Reporting Assistant. We ran three of the built-in subsystem tests (CPU Arithmetic,
The Sandy Bridge-based Core i5-2520M easily wins Sandra's synthetic arithmetic test, though the more powerful CPU in the U260 is competitive.
The ThinkPad X1's processor is the only chip capable of using Intel's AVX instructions; the x32 test only runs on an SB-class processor. The ThinkPad X1 easily surpasses all the competition.
Again, there's no real contest here. The IdeaPad U260 offers nearly double the X120e's memory bandwidth, but the ThinkPad X1 is twice as fast as it in turn.

The X1 has no trouble with HD video playback; even 1080P output barely stresses the CPU to noticable levels.
