On CPU RAM does provide much faster performance. That’s the reason they are going that route.

It's part of the reason why RAM was always placed close to the CPU on the motherboard anyway. The farther they are apart, the more time and energy is used to transfer data and instructions between them.

Right, it s a physics issue, not greed. I mean, they’re going to make a margin off of it for sure but that’s not the sole reason to do this.

I'm imagining a world with desktops and laptops that have On-CPU-RAM and On-Motherboard-RAM with the traditionally slotted RAM acting as a swap for the On-CPU-RAM.

I mean, isn't that in principle how old swaps traditionally work? They take up some space on your slower disk drive to "swap" data from RAM onto when out of RAM. On-Motherboard-RAM, since it's slower than On-CPU-RAM, could achieve the same purpose, meaning limited On-CPU-RAM wouldn't be as impactful.

Greed might not be the main driving force, but it's absolutely there too. I predict on-cpu ram costing more than it should in the future due to lack of competition. (yes I know there aren't that many manufacturers of the actual chips even today when the consumers can choose from many brands of ram sticks)

Which makes a lot of sense as RAM speed is the one big bottleneck.
