The Asus K52JC is one of the first laptops we’ve seen to come equipped with Nvidia’s Optimus technology. This automatically and instantly switches between the integrated Intel graphics chip and the dedicated Nvidia GeForce 310M graphics chip when appropriate. You should therefore benefit from the power-saving Intel chip when you’re working on battery power and the faster 3D performance of the GeForce chip when you’re playing games on mains power.
In our tests, the K52JC lasted just over four hours in our light-use battery test. This is a respectable length of time. However, the GeForce 310M didn’t impress us, managing just over 15fps in Call of Duty 4, making us question its value. Windows application performance is good thanks to the Core i5 430M processor and 4GB of RAM.
We were quite taken with the K52JC’s understated black and brown livery. The base feels very sturdy, although the lid doesn’t tilt back especially far. This could make it difficult to get the optimum viewing angle when placed on your lap. As expected, the built-in stereo speakers lacked bass. They don’t distort at high volumes but, as with most laptop speakers, are underwhelming when listening to music or watching programmes on iPlayer.
The Asus K52JC is a good laptop and the automatic graphics chip switching works surprisingly well. However, the battery life and 3D performance isn’t significantly better than cheaper laptops. In fact, Dell’s Inspiron 15R costs £70 less yet has better 3D performance and lasts only half-an-hour less.
