I've seen this link before...the computer actually looks like a snag compared to the rMBP for $1000! Of course it'd be $1,300 for the same sized SSD. Still, 1k cheaper for same specs, with same low eight and slim design (not as slim). Anyway, point of my post here:
Looking at the "Intel Iris Pro graphic Scores" table on their site they give a few "benchmarks" for games.
Bioshock Infinite ("Very high") 29 FPS
Bioshock Infinite (Medium) 42 FPS
Tomb Raider (Ultra) 31 FPS
Tomb Raider ("Normal") 59 FPS
Starcraft 2 (Ultra) 41 FPS
Starcraft 2 (High) 68 FPS
Starcraft 2 (Medium) 69 FPS
------------------------------------------------------
Comparing to the Nvidia 650M's benchmarks from Notebookcheck:
(
http://www.notebookcheck.net/NVIDIA-GeForce-GT-650M.71887.0.html)
Bioshock Infinite (Ultra - Assuming "Very high" means ultra) 17 FPS
Bioshock Infinite 56 FPS
Tomb Raider (Ultra) 14 FPS
Tomb Raider (Medium - Assuming "Normal" means medium) 54 FPS
Stacraft 2: (Ultra) 25 FPS
Starcraft 2: (High) 65 FPS
Starcraft 2: (Medium) 88 FPS
-----------------------------------------------------------------
So if you look at the comparison's of those games specifically, it's kind of weird. Because Overall it would seem the Iris Pro does 15-25 FPS better in some games on Ultra, but then you have it performing 15-30 FPS worse on some games in Medium settings..I'm not sure how to explain the discrepancies there. It could be that these games were specifically picked out to show Iris Pro's best case scenario, but even so it's weird to compare.
The point of the point though, is that the Iris Pro's graphics seem to be completely acceptable. In terms of casual gaming. I'm assuminggggg these benchmarks were done in 1366x768 resolution, and that the 650M would still carry through better into the higher resolution of 1080p though. Just thought I'd post this though, to see other's comments
