rMBP Iris Pro vs 750M GPU - battery comparison???

[ekinnyc]

hi

was wondering if anyone has experience in how efficient the rMBP with the dedicated GPU versus the one with just the integrated Iris Pro in terms of battery life?

I get about 7 hours from the Iris Pro.

I'll run it tomorrow on the 750M and let you know.

I get about 8 hours by using gfxcardstatus to force the GPU into Intel-only on my 2.6/16/1TB/750M late-2013 machine.
