What processor does the base rMBP exactly use?

[golu14]

Googled it, and found mixed answers.

I know it uses 2.3-3.3ghz i7 but is it 3615qm 3615qe 3610qm or 3610qe ?

It uses the 3615qm.

I've only seen the QM variants in the Geekbench reports. I think the base model is 3615QM and the 3720QM for the higher model. I suspect the ultimate model uses the 3820QM.
