Yes, just a bit, so let???s clear up the differences right now as it???s pretty simple:The dm4t has an Intel Core i3 processor while the dm4x only offers a faster Intel Core i5 or i7 processorThe dm4t offers only integrated graphics while the dm4x offers an upgrade to dedicated AMD 6470M graphicsAnd that???s it, everything else including the design and build are the same between these laptops.
