Nvidia would probably have wanted some serious money or secure design wins for many generations and then dictate higher prices because Apple would be locked in.Disable Discrete Graphics on MBP How to disable discrete graphics chip on MacBookPro with broken Nvidia/AMD chip They say it saves a bit of power when the dGPU is active but that makes almost no difference and way more power is lost by unnecessarily running the dGPU way too often. I am not sure if it is still the case but nvidia and AMD gpus didn't enter the lowest power states with an external screen even if there was no real work to do.Īpple didn't do it the other way because Nvidia was obviously not willing to help them write an optimus driver for OSX and that such a driver is difficult is shown by how long it took AMD to get there own working well. Resolution alone really doesn't make a GPU sweat at all.ĭriving the 2GB GDDR5 memory the memory controller and the dGPU even in a low power state is significantly less efficient. Smartphone chips today can drive lots of pixels and they are still a long way from Iris Pro performance. A dGPU in the lowest power state sucks way more power and it helps nothing. The iGPU can clock all the way down to the lowest power state and up almost instantly. Just pixels aren't much of a problem for the iGPU which can handle 2x 4k monitors if it had to. That dGPU stays in a fairly low power state clocked down to less than 200Mhz it is actually not all that fast. That doesn't sound like much but it is if you consider that average total power draw for 8h battery life is about 11W. Just having the dGPU active add some 5+W. You essentially have to restart all the troubled apps if you unplug the projector und want to go back to igpu only.Ĭlick to expand.It would be more efficient. You can force it sometimes but the application performance is horrible and there seems to be some software fallback to prevent crashing. Many applications that would trigger the dGPU cannot just switch back to the iGPU. Even if set to iGPU only it will automatically switch to dynamic switching or dGPU only as soon as it detects the cable. GfxCardStatus usually recognizes when an external screen is plugged in. It is not an OSX problem, it is a hardware problem. Because Nvidia for Optimus makes the iGPU the sole video output handler.

That is also why you couldn't use any Optimus drivers in Windows even if the iGPU would show up without loosing external GPUs. It is wired to be physically impossible to use the iGPU in these situations.

If you hook it up to a projector and show some powerpoint slides, or if you just read a pdf or watch a movie on a bigger external screen. Everything that you plug into a video port will trigger the dGPU (if there is one). Unless Apple changed something this generation, the dGPU is the only one that is connected to the output ports.
