Not all of that relies too much on your gpu. You shouldn't experience a noticeable difference editing photos. Video varies by the package used, and in most cases leveraging the gpu isn't something that is necessary to the core toolset. There are different aspects to these things, with the first being whether the drivers can draw something to the screen as intended. The second is additional processing done to framebuffer data. The third would be leveraged use for additional computation, such as the case of either compute shaders in OpenGL/OpenGL ES and OpenCL frameworks. Your photo editing wouldn't be affected much by the latter. Video might depending on package. 3d work depends mostly on the second, although there have been attempts to write various solvers in gpu frameworks.
In spite of what I mentioned, I still understand why you would wait.
Autodesk Maya defiantly requires a dGPU like the 750m though. I have heard of very bad experiences with Intel's Iris Pro GPU and Maya. All I can say is that rendering is blazly fast and real time rendering through viewport is also solid. I'm sure that is is mainly GPU sided.
And what I meant in my comment you were replying to was if I had a 4K iMac, I want to be able to do all the stuff I do right now in 1080p in 4K. I.E. rendering animations in 4K (which I can't see any moble GPU being able to do as fast as my GPU does it in 1080p), 4K video editing/ transcoding/ encoding...
Tasks like that align with the strengths of the gpu. They tend to involve highly parallel floating point calculations. That falls into territory aligned with the gpu. My comment about photo editing was that most of those applications could benefit from it, yet it's not necessarily crucial to performance. In that sense they operate in favor of smooth operation on a very wide range of hardware, regardless of if the gpu supports certain frameworks. I have not tried maya with the Iris gpu. Typically Autodesk will test available hardware when a new version of maya is on its way out, and they do list known problems.
The problems appear to come from the lack of VRAM. Using DDR3 shared memory appears to be slowing it down. Anyway, I felt the same way about the first line of retina MBP's. The 15" with the 650m was great but if you got the HD 4000 with a retina screen, that spells trouble.
Ps - sorry if my grammar or knowlage appears to be slight off or lacking, I'm extremely tired right now
Meh. That would just be copying the Windows Surface design and not a notebook computer.
How do you know this? It seems a strange direction to go with the overwhelming success of the Surface.
It would seem that a product like this would be worse than it's individual components, the worst of the Air, the worst of the MacBook.
I think Tim Cook even said that in an interview. Combining the two just makes a subpar device where you still need to own a laptop and a tablet. I concur with that. I was a surface 3 sucker, so glad it was within a return period. It's neither laptop nor a tablet.
