Heck yeah. We want our performance boost and we want it now!

The problem is there isn't enough incentive to force the issue yet with software developers. If the article is to be believed, a 300% to 500% performance increase is big enough to prompt a big push from AMD/Nvidia/Intel to make it happen.
But it's the driver that communicates the data to the GPU.
The software would be the same, the driver would tell the data where to go. It sounds like you're just making stuff up.

This sounds interesting, and honestly even in regards to drivers idk why there hasn’t been any multi gpu cards in so long. I miss the days when we would get a gtx Mars II or a Radeon ***x2. Or xx90 / x90 from both sides of the fence.

Given the expenses of the hbm memory for AMD if they had produced as many Vega x2s as they did Radeon VIIs at its launch they’d be a distant memory. Or even with the excess of Polaris GPUs why they didn’t implement it. Course same could be said for Nvidia with they’re overflowing 1070s that simply won’t drop in price(which every 1080p gamer would love at the rx 580/590 price point)

Just me though, my rig only has room for a single gpu(itx sugo13) Which I only upgrade at a double the performance mark at a sub $xxx price point. And seeing as I’ve got the 120 aio cooler for the cpu the selection really dwindles.

I wonder what kind of TDP a 3 GPM or 4 GPM configuration would generate?

You mean like the person who wrote this article? It sounds like pure fantasy to me. I mean it sounds nice but it does not remove the problem we have now...which is making multiple gpu's work the same work flow simultaneously.Sure all the modules on the wafer can talk to each other,still has to get to the user. This just increases the size of the problem.

The whole thing. Made up solutions with a made up problems.
mGPU actually works quite well, just not for games. We're an afterthought and devs work with the hardware. If Chiplet GPUs become a thing, people will learn to work with it or around it.
Just look at RTX. Hardware that was given a purpose it wasn't made for so they could sell it. Performance is terrible for now but time goes on and people learn.

So this is what it takes to make "MOAR CORES" popular,someone besides AMD?

An 8% increase in speed across the board on all GPU used for graphical display and gaming can be had simply by putting a separate frame buffer chip on the card between the existing tech and the output ports.

This 8% is achieved by NOT INTERRUPTING the graphics generation to send frames to the display and instead having the card itself put the frames to the buffer at full card speed instead of having to slow down to transmit speeds of whatever connection you have to your monitor whether it be 22" DP1.2 or The Verge's magical invisible unicorn intestine clad 18 foot 144hz HDMI cable they showed in use at the end of the "How to build a computer" video.

Latency! It is a huge issue for many workloads, not all, but many.

Hardly a made up problem.
