Intel has been competing with AMD using its traditional monolithic approach to processors and unfortunately, that can't really scale to compete with MCM based designs like the one AMD employs. Limited by the reticle size, you can only expand a monolithic die so much - not to mention yield has an inverse relationship with die size. MCM based designs on the other hand not only benefit from increased yield but are also able to scale almost infinitely. If Intel decides to shift to MCM based designs, it can quickly ramp up its performance numbers - something it direly needs to do in order to stay competitive with AMD. For their sake, I hope this project was one that ended successfully and had just been keeping a close lid on and not something that was eventually abandoned.

indeed, they're mostly dead shorts with some control signals around the outside

Just slapping chiplets together with glue (yeah that glue joke from Intel really worked out good) isn't going to solve their MT scaling issues, when they just use multi ring bus mesh...

That's why this isn't released as mainstream. It's not effective outside of whatever niche use it has.

They need a new uarch.
