There might be some typos in there...
I would guess that the Haswell Core i3 CPUs would have the GT2 variant of the new graphics core; the Intel HD 4600. Not a holdover of the the Intel HD 4000 from Ivy Bridge.
The high end quad core mobile Core i7 CPUs would likely have the GT3 variant of the new core along with eDRAM. Therefore, instead of the just a mere Intel HD 5100 it would actually be the Intel HD 5200 + eDRAM. That is also known as CrystalWell and it is likely to end up on in the BGA socket (meaning embedded) desktop Core i7 CPU as well.
Additionally, I would have thought that the "non high end" dual / quad core mobile Haswell Core i7 would be getting the Intel HD 5200 graphic core, not the Intel HD 5100 found in the mobile Core i5 CPUs.
