First AMD Radeon MCM GPU later this year as Instinct MI200 (multi-chip module)
AMD is reportedly planning to release the Radeon Instinct MI200 this year, which will use the Aldebaran GPU with CDNA2 architecture and MCM technique for the first time. As a consequence, the graphics card's shader count should be impressive.
While RDNA2 is the successful successor in the shape of the RX-6000 graphics cards since fall, the CDNA2 graphics cards have not yet been launched. The Radeon Instinct MI200 will be the first CDNA2 graphics card to be delivered to selected partners. According to an AMD presentation, sales should begin officially this year.
The Radeon Instinct MI200 is said to use a GPU named Aldebaran. This should be the first GPU not only based on the CDNA2 design, but also with an MCM structure (multi-chip module). MCM is a notion that is already known from AMD's Ryzen processors: several CPU chips and an I/O chip coexist on a single substrate. The Aldebaran GPU is claimed to be built on two chips, each of which has 128 compute units. Although a total of 16,384 shaders are anticipated to be used for the entire expansion of the GPU, it is predicted that some of them will be turned off as we so often see. Finally, on the Radeon Instinct MI200, Aldebaran will be paired with a generous 128 GB of HBM2e memory, making for an impressive combination.
A great deal may change in the future as a result of the advent of MCM technology in graphics cards. Thanks to the MCM method, which involves constantly putting the same, tiny CPU chip in a variety of different configurations. It is possible that a similar evolution may take place in the next several years in the case of graphics cards, such that future gaming graphics cards will no longer depend on a single chip, but on a number of chips.

I think that is dead: the basis of MCM is that each chip talks directly to each other, no bridge chip is used and the path is tiny rendering a small latency penalty.
Adding another card will have the same problems of the past, so I believe both SLI and Crossfire are dead.
absolutely.
at first it will come at familiar price points as the easiest to make and sell for gaming will be the basic "chiplet" on it's own card. that will answer any question of availability and you can have the familiar disabled or not shader count making for at least two versions at the lower end.
for the enthusiast level they will use MCM, it will easily surpass Xfire/SLI without any of the problems including drivers.
for the really high end you can have multiple chiplets and a large socket to radically dial-up whatever performance level you want Nvidia to struggle to hit for a few years.

We need a new platform, motherboards with cards the way we got them now is too old school, Image a computer that its build like a car engine, in 3D, where you can integrate cooling systems right inside the hardware and add GPU or CPU modules like cylinder heads on a Gas Engine

can be done except for I.P. plus the more complex a system the greater chance of breakdown.
there is no way that this can be done legally because of patent laws and if someone licenses the patent great. now you have a console trapped like a fly in amber.

as far the "bridge chip " is the one pretending to be the gpu and schedules the 2 or more mcms to do rendering task with out the graphics engines being aware there are 2 gpus working on it ...as far it does a good job ... it will be the holly grail of multichip gpus ! I am still waiting to see results of it since a lot of things sound awesome in paper and on execution some times are underwhelming , that said this looks very promising !
