I think being able to Display an Image at 5k is being used as a smokescreen to what a crap budget GPU's these "PRO" laptops have. Its a step sideways IMHO. I have used and tested Final Cut Pro X, Resolve, Adobe CC with the FASTEST OpenCL cards out there. OpenCL is not keeping up and Adobe CC and Resolve are un-usable with OpenCL. We all switched to CUDA/NVIDIA for Profession video and graphics. And we RUN circles around anything AMD offers.
Its a total smoke screen to have people say the laptop does 5k, and my laptop renders Final Cut Pro X, really fast..
well can it do anything else? Any other apps? Any other workflows? no, not quickly or efficiently.
Also we where testing all the fastest GPU's AMD had to offer. R9 and now the RX 480... OpenCL was just crap. I have done programming, OpenCL on paper is amazing, but it is not being utilized by the professional software makers and its not fast enough.
Their are other possible benefits of AMD GPU's, but my industry, TV, FILM, EDITING, VFX, COMMERCIAL PRODUCTION and MOTION GRAPHICS, Nvidia's are just dominating..
The RX480 is a $100 GPU in a $3600 laptop, its total BS.
