    Hello everybody!

    This is my first thread so nice to meet you guys, my name is Davide.
    I have already ordered the Macbook Pro 15"with 2.7GHz Quad-core Intel Core i7, Radeon Pro 455 2GB, 512GB SSD anf 16 GB Ram.
    Now I start thinking that maybe I shoulde have ordered the one with 2.6GHz, same Ram and SSD but Radeon Pro 460 4GB.
    Because probably I'm still in time to cancel my order, what do you think is better? more GPU memory and less CPU Ghz and cache or less GPU memory and more CPU Ghz and cache?
    I'm a photographer and architect so I will use the laptop mainly with Lightroom, Adobe Suite, Autocad or similar and 3D modelling softwere like SketchUp.

    Thank you very much guys!

    Sound's like you need a upgraded Graphic card over the CPU power.

    I'd lean towards the 460 over the 455, that extra 2gb of ram will be useful for 3D modelling on other platforms such as Revit

    Not familiar of the specs of the programs you use but to be more futureproof, I would cancel your order and go for the 460 4gb option.

    Get the pain of cancelling and re-ordering now rather than kicking yourself in the @$$ later on for not going with the 460 4GB video card.

    Both are not the great GPU... so if you really need more GPU power you should go for a eGPU or a more robust desktop. I would stick with better CPU... and if necessary get e eGPU when available.

    I would agree with the first two posters and go for the enhanced GPU over the CPU. You will probably not notice a huge speed difference with the slightly faster CPU clock, but the doubled memory on the video card will likely make a much bigger difference.

    You could go with an external GPU as VMS said. While I don't have any experience with these, I imaging they would be the best of both worlds. However, it sounds as if your decision of one or the other is due to cost, and an external GPU would be an additional cost (although one you can wait and buy later).

    The Radeon 460 is capable of 1.8 TFLOPS, while the 455 is at 1.2 TFLOPS and the 450 at 1.0 TFLOPS. The jump from the Radeon 455 to 460 is significant, a 50% increase in theoretical performance. On the other hand, the difference between processors is not nearly as wide. The quality disparity between the GPUs is going to have a much larger impact than the CPUs with your workflow.

    Go with the Radeon 460/512 SSD option. I'm waiting for that exact configuration to arrive, can't wait.

    Thanks for the answers. Honestly I don't model a lot. The machine will mostly be used with the other softwares I listed above and for everyday uses.
    While I understand the importance of a GPU, which kind on user would go for a better CPU and worse GPU? When the difference between the two CPU is appreciated?

    Thats difficult to say. Probably someone who can benefit from a slightly faster CPU but doesn't really need a GPU? Like people working with certain numerical tools that are not GPGPU enabled? Statisticians? There are still a lot of app there that can't or don't benefit from the GPU.
