    I'm considering to buy a macbook pro 13" with intel iris gpu.
    Does this gpu have its own memory or it uses from the 8gigs system RAM ?

    Besides, if we compare the intel iris with NVIDIA GeForce GT 840M 2GB, how much better is the geforce ? Would there be a huge performance difference ?

    The Iris series are integrated chips and thus use the system ram. The 840m is significantly more powerful but neither are powerhouse cards that's for sure.

    What games are you planning on playing? If you're just going to be playing World of Warcraft or Counter Strike the Iris is plenty fine.

    Intel Iris uses memory from the system RAM when needed and up to 1.5gb.
    It has no own dedicated memory.


    The GeForce is much more powerfull, depending on what you need it for.

    Not planning to play any games but will be doing 3D modeling on solidworks or 3ds max.
