Performance
Which is also borne out by the all-core CINEBENCH test. Going by previous experiences of correlating the benchmark to real-world usage, a score of <1.5 means that the laptop shouldn't have any difficulty running the CPU component of any modern task. The CX640's 2,61, then, is plenty fast enough.
The CPU also helps in the venerable DX9 benchmark that is 3DMark06. Here, the NVIDIA Optimus switching technology puts the load on the GeForce GT 520M GPU, though it's actually slower than the IGP part of AMD's latest mobile processors.
Putting some real-world context on it, the Llano machine, with Dual Graphics active, returns an average frame-rate of 43.4fps when running Just Cause 2 at 1,366x768 with low/medium-quality settings. Meanwhile, the MSI provides a sticky 18.4fps in the same test.
Pretty frugal when running a 720p video via the onboard graphics, the CX640 should have decent battery life.
Run in Entertainment (balanced) mode and the CX640 provides almost three hours from the 47WHr battery, which is good for a mainstream laptop, and it's a shame that a larger-capacity model isn't optional.
