Gaming: Iris vs Iris Pro; 13 vs 15

[JoeFig44]

How many extra fps would I get on avg between the iris and iris pro integrated graphics in the late 2013 Mbps?
Mainly on Warcraft, but also other medium intensity titles

Also, can u game well on the 13" screen, or do you really need the 15" screen size?

There's definitely a difference, but I don't know how much.

The screen size it obviously a personal preference.

the 13" rMBP will run the majority of newer games at low - medium settings. The 15" rMBP will do the same at medium - high settings. An older game like warcraft will run very smoothly on either system. I decided to go with the 15" for the faster gaming. I would have chosen the 13" if it had the same chip.

Here's two links for each of the chipsets performance. Scroll to the bottom for actual gaming framerates, keep in mind you'd probably get slightly better results than what you see:

It is about 70% more performance for graphics. Iris Pro is also a fast quad core chip so there is less CPU limits which means more particle effects and huge unit sizes in games like total war, better at minimum frame rate in multiplayer.
