Chips higher than the 2620M do not have Intel graphics (Ironlake) and so they must have discreet video from either NVidia or ATI.
Actually, that's not right. In Sandy Bridge generation, it might be a thermal problem. 2620M is the highest part that stays inside the 35W envelope which has been as high as Intel mobile parts have gone, historically. It sure seems that companies are only shipping these 45W chips with laptops that also have cooling assemblies for discreet graphics. Also, in the T520 series, the motherboard is slightly different.
