Performance and Benchmarks
With the combination of the second-gen Intel dual-core processor running at 2.6GHz, Intel HD graphics, and 4GB dual-channel RAM at 1333MHz, this notebook is able to breeze through everyday office tasks and then some. We watched a couple of HD 1080p videos, had several office productivity programs open, and listened to music at the same time without any problems. Generally speaking, the notebook scored about the same as most other business notebooks in this price range ($1000) in the synthetic benchmark tests.
