Why would you want your external GPU built into the display? When I saw the headline, I thought maybe it had a webcam and the A13 would do things like portrait mode, before the image reached the computer.

I don't know, but my guess: Apple Exec: "Build an external display for the iPhone and/or iWatch." Apple Engineers: "Ok, but we will need a GPU built into the display or it'll look like shit. It'll also need a lot of RAM/SSD to store textures, etc. Additionally, a high bandwidth, low latency wireless connection between the iDevice and the display (e.g. UWB)." Previously to support an enormous external display the iDev…

macOS uses a PDF-like canvas as the core display engine^, upon which everything writes object layers that have refresh loops independent from the main canvas 'flatten layers into the display' loop. This is all inside WindowServer, and is why lets you select an entire window including the shadowed border, without picking up anything from above or beneath it, because Spacebar activates object selection mode. And we kno…

Arguably what's an appropriate GPU bandwidth is largely defined by the display attached to it, primarily its resolution, color depth, and refresh rate. But I still don't think it makes sense to physically merge the two. Displays wear out far faster than the GPUs driving them, and just have much higher failure rates in general, being physical targets for thrown handheld controllers and what not. Doesn't seem wise to m…

> Displays wear out far faster than the GPUs driving them, and just have much higher failure rates in general, being physical targets for thrown handheld controllers and what not. Doesn't seem wise to make the display so much more costly to replace by shoving the GPU within it. Is this true? This seems nearly diametric to my experience.

> Displays wear out far faster than the GPUs driving them Do they? In my experience they both last forever until you decide to upgrade to better specs. And in that case it's quite likely you upgrade both together. Displays don't really "wear out" these days in normal usage. Although I guess I'm not really sure why you say they're a target for thrown handheld controllers ha... are you speaking about yourself or about…
