newtekie1 At least nVidia always makes some way to tell the difference between the different cards.

Is that so.Usually when you buy a card that has different amount of memory, you assume the GPU is the same. Like it has been for years before. Example RX480. Both 8GB and 4GB have the same chip underneath.MX150 has 2 variants (or was it the mx130 hmmm). One is the default (being advertised as such) and its, in name, indistinguishable slower brother, pushed into the market in silence. You wont know which one you are getting until you buy the laptop and run GPUZ, at which point it's too late.As for AMD side of story, we have the 550 with different specs in the same name and I believe a 460. The new 580 for the Chinese market has it's core count in its name on the Chinese website.So please explain to me how is one company better than the other and vice versa, considering they do mostly the same stuff.
