| Re: Laptop graphics minimums |
the 4600 is the bare minimum and uses the onboard system ram. the NVidia 740/760/770 are the powerhouses. many better laptops today have nvidia optimus tech in them. for the mundane use the machine uses the built on the chip 4600 when a heavy graphics load goes online it seamlessly kicks over to the on the board NVidia discreet video with its own built in fast memory unloading the CPU.
many graphics based programs like PS and DxO use CUDA (NVidia), openGL and OpenCL(AMD) languages to up the performance by using the discreet GPU and its very fast available discreet memory
the difference in performance for said programs is very noticeable. so is the power drain if on battery. you can turn it on and off to from the discreet cards control panel.
the intel 4600 is a good basic chip but doesn't quite have near the capabilities of discreet products
I have the 4600 in my surface pro 2
