> The "laptop"/"desktop"-grade chip distinction is pretty arbitrary here.

This is the first of their CPUs. The iMac will almost certainly be running a higher end CPU which at the very least supports more RAM. It's likely the 16" MacBook Pro and the higher end 13" MacBook Pro will share a CPU with the iMac the same way the Mac mini and the MacBook Air share a CPU.

I think the holdup for the iMac is not the CPU, but rather Apple's discrete GPU which is not ready yet.

For replacing the Xeon-W in the Mac Pro and iMac Pro, they will also need a higher performing CPU, sure.

I hope they offer an option for integrated-only for all their product lines going forward.

The 16" MacBook Pro is only available with a discrete GPU, which I don't need but causes me tons of issues with heat and fan noise. The dGPU has to be enabled to run external monitors, and due to an implementation detail, the memory clocks always run at full tilt when the resolution of driven monitors doesn't match, resulting at a constant 20W power draw even while idle.

The distinction theme between labtop and destop is customization, integration, and maximization. Apple Silicon is not going to destroy case/fan/liquidcooler/fancyLED/GPU/Motherboard/etc industry. It's still crystal clear distinction.

EDIT:// sorry, i misread/skip the "chip" part.
