Once again, we’ll start with some Tablet comparisons. For today though, we have to test what we have, and that’s the GT2 i5-6300U. The Surface Pro 3 could also be had with Iris graphics, but architectural differences aside, there was no eDRAM and it had eight less execution units on the i7 model.Īll three are going to perform somewhat differently, although it would be pretty interesting to see what kind of a difference GT3e would make at this sort of TDP level.

The GT3e model has a maximum frequency of 1.05 GHz. This is somewhat special because it includes 64 MB of eDRAM as well as doubling the execution units from 24 to 48. Finally, if you select the top Core i7-6650U there is a bit of an upgrade, with this processor sporting the Intel Iris 540 graphics which is the GT3e model. The Core i5-6300U, which is the processor in the review sample, steps up to Intel HD 520 graphics, which has the same 24 execution units but with a maximum frequency of 1 GHz and more overall headroom for reduced throttling. The base model is the Core m3-6Y30, which has the Intel HD 515 graphics with 24 execution units and a maximum frequency of 850 Mhz.

The Surface Pro 4 has the option of three GPUs depending on which model you choose to go with.
