So i was hoping for a MBP refresh with haswell but unfortunately that didn't happen. My question is how does a low voltage i7 1.7GHz HD5000 stack up against the mobile i5 2.5 HD4000. I love the 13 inch form factor and I will mostly Develop on it with a touch of Civilization V on it. Im not looking for a gaming laptop but wich do you think will do better with 3D rendering? Is there any benchmarks out yet of the Low volt Haswells? Thanks in advance.
