Much like NVIDIA's MX150 graphics cards before them, the new MX 2250 have been silently separated into two different SKUs. The difference, which is almost impossible to tell by comparing two MX250-powered solutions in a brick-and-mortar store (let alone in an online marketplace), can only be differentiated via their version ID (unless the vendor specifies what wattage version they're using, which isn't very likely). A low-power, 10 W MX250 carries the '1D52' ID, while the faster, 25 W rated part carries the '1D13' identification.

The power envelope difference on these parts means that performance is being gated at the clock speed level, and if the MX250 SKUs go any way close to their MX150 predecessors, we're looking at some 30% difference between parts. Now, if vendors do discriminate which version they've installed - the 10 W or the 25 W one - then all is good - the consumer knows what he's buying (or at least has the info to do a quick Google check), and manufacturers are free to choose which version to implement on their designs, whether favoring performance or battery longevity. If not, well... You should use GPU-Z on your laptop as soon as you can, because you might be carrying a 10 W part while counting on 30% more performance. And not knowing that before purchase really is a light kick in the proverbial for users, especially if it's done only via version number,s which the majority of prospective PC buyers won't be aware of.
