We see it similalrly:It was reported that Apple scrapped the "M1 Extreme" because it was too expensive to manufacture. Sounds like the same has hit the "M2 Extreme" and "M4 Extreme".
Maybe when we are in mainstream sub-micron process ranges using chiplets the cost will become acceptable.
a very small niche who still need a Mac with PCIe slots
GPUs can and are used for AI training and inference. NVIDIA has GPUs that have special functional units designed to efficiently handle AI workloads while also providing great GPU performance. However, if the primary goal is AI then supporting other GPU workloads ends up wasting silicon.I bet the AI server chip architecture could be readily adapter to a dramatically increased number of high-performance graphics cores. This is an area where Apple has done ok, but has fallen significantly behind the class leaders. I live in hope!
Too slow. I think that Apple has passed beyond that approach with on-die interconnect.I've been wondering for years now why Apple doesn't make another dual processor Mac Pro, like they've done in the PPC and early Intel days. It would greatly improve the case for the Mac Pro above the Mac Studio and would actually provide the necessary slots for all the expansion in there (now there's not enough bandwidth in the SOC to actually use all expansion slots at full speed at the same time).
There simply isn't a market for the Mac Pro, it's as simple as that!
Apple this "past summer" canceled the development of a high-performance Mac chip that would have consisted of four smaller chips stitched together, in order to free up engineering resources for a planned AI server chip, according to The Information.

Based on the report's description of the chip, it sounds like Apple has canceled a previously-rumored "Extreme" chip for the Mac. It was previously reported that an "M2 Extreme" chip was scrapped a few years ago, but perhaps Apple had revisited the idea since then. In any case, it now sounds like an "M4 Extreme" chip is also unlikely.
Apple likely would have introduced the "M4 Extreme" in its high-end Mac Pro tower. The chip would have offered even faster performance than the M4 Ultra chip that is expected to launch in new Mac Studio and Mac Pro models later next year.
If the "M4 Extreme" were to have been a quadrupled version of the M4 Max chip that debuted in the MacBook Pro a few months ago, it would have had massive specifications, including up to a 64-core CPU and up to a 160-core GPU.
While the "Extreme" chip may be off the table once again, it seems like Apple has repeatedly shown interest in developing such a chip, so perhaps it will eventually materialize as part of the M5 series or later. For now, though, the wait continues.

So you are saying you don't think Mac OS already has the capability to do task assigning for multiple cores?Well you would also need software to do the task assigning for all those cores, and that may have been too much for Apple.
Too bad, probably already a sign of the end of the road for those M chips, at the very least we’re moving towards a plateau which will probably be countered with an increase in clock speeds.
I cannot imagine using a product that makes me feel that way. You really should talk to someone and remove yourself from that situation, rather than posting on a rumors website for them. It sounds extremely unhealthy.The reason that this is a "very small niche" is that Apple drove almost everyone who needed slots over to Windows. Same with internal storage, and other features common in Windows PCs, but stupid-expensive on macs.
I still use Apple these days, but I feel very trapped and taken advantage of, and do not recommend Apple to friends.
scrap the entire Mac Pro line

I'm not in this group, but it doesn't seem that hard to understand. People who want more CPU know they want more CPU, the exact performance number isn't needed to know that a bigger chip will be closer to what they want.Interesting to see people refusing to buy a Mac Pro without the Extreme chip because they absolutely need the features and performance of the Extreme without even knowing what those features and performance might be.
The Apple Silicon architecture may not be designed for multi-processor operations so performance would not scale and you may hit issues with memory access and cache coherency.
This sounds like what is happening with these "Extreme" SoCs - the Ultra is not twice as good as the Max even though it is two Max connected directly. Two Ultras talking to each other across an external connection on a motherboard would be even worse.

But more than CPU power, plenty of vocal people want the RAM that the old Mac Pro offered, and have been complaining ever since the switch to Apple Silicon. Here it's easily to play the extrapolation game. 2x Max's RAM for an Ultra, and 2X-4X Ultra's RAM for an Extreme (if an Extreme is a 2X or 4X ultra). Considering Apple RAM pricing, selling just one unit would cover all the R&D costs.![]()
It was really going to be called Extreme?
I guess we should pour one out for M4 Radical, M4 Totally Awesome, and M4 Most Excellent Dude. 🏄♂️
But that's just it: an M4 Ultra would have more CPU power than any other M4 out there. Yeah, I always want more CPU power myself. People are talking like they can't buy the next Mac Pro unless it has an M4 Extreme in it without knowing what an M4 Ultra could do or how much better an M4 Extreme would be or what features it would have. They just want a chip called something else, but they make fun of the name on top of that.I feel like at this point the Mac Pro suffers more from the loss of flexibility than the gain in raw power. As you say, the people who just want max CPU and RAM for their custom software know who they are.
The rest of us might like to use those PCI slots for more than just giant SSDs but Apple doesn't seem to think so.
Has Apple ever named a product with the 80's tag "Extreme"?
This is somebody attempting to manipulate the stock, that's all.
