If you are looking for a thin and light PC with discrete graphics and are attracted to products that boast of employing an Nvidia GeForce MX150 GPU, then perhaps you should take a closer look. NoteBookCheck has been through its extensive collection of MX150 equipped machines and found there's a peculiarly wide range of GPU performance on offer between otherwise similar machines. A machine that contains a GTX 150MX 'N17S-LG-A1' or '1D12' variant can offer 20 to 25 per cent less 3D performance than a 'standard' MX150. That's a big drop on the 'good enough for mobile' solution you might think you are settling for.

Nvidia doesn't mention the various MX150 models on its dedicated product pages. It merely claims that the MX150 is up to 4x faster than Intel UHD 620 graphics. There are many other speed comparisons in an associated blog post from back when this mobile GPU was launched in May 2017.
