    So with the new retina macbook pro coming out on tuesday apple switched from having both intel integrated 4000 (500MB) and a Nvidia chip (1GB) to a single iris pro graphics. I know the performance is different across all three chips but before it was offered with 1.5GB total of graphics. So how much does the iris pro contain? Thanks just wondering

    The Iris Pro has a 128MB on-chip DRAM cache (dubbed "Crystalwell") and shares up to 1GB of main memory.
