POWER11, "Cirrus+" Can any of this be substantiated?

[Borley]

From a speculative write up on big data processor roadmaps:

Just for fun, and to show what a different world it is that Big Blue operates in, we added the Power and z processors to the middle of the Arm pack. We expect “Cirrus+” Power11 and “Telum II” z17 processors before the end of this year to boost the performance of the Power Systems and System z mainframe lines. The Power11 chip, which we will cover shortly, is all about increasing memory bandwidth and memory capacity compared to the Power10 chip the has been in the field for nearly four years now. The z17 processor has a bunch of tweaks, including an integrated DPU to speed up I/O operations for mainframes, which we covered back in August 2024. Both of these chips are etched by Samsung, IBM’s processor fab partner, and both have sixteen cores on a socket and are implemented in machines that have four sockets in a node, four nodes in a single system image, and tens of terabytes of main memory hanging off of them.

Big iron is truly different.

I'll admit to not having been paying attention to things after IBM mucked up with nonfree memory controllers, but was surprised to see sixteen cores being referenced. Despite other material suggesting 25% more cores as compared to POWER10 (which was also configured with 16 cores).

Haven't heard of this yet but maybe some stuff has leaked from the NDA partners.

I also read something about the production processes of the future Power 11 and I read that they will still use a 7 nanometer even if improved and refined compared to the previous one. Only my question arose spontaneously... Why, in 2025/2026, where the 2 nanometers are getting ready to arrive now and where IBM was also the first to come out with this process years ago, still wants to produce a production process that although I understand it is proprietary ok, in the end IBM customizes all its processes and gives the directives to those who produce them to make them only for it, is now outdated? How come, having this technology first and obviously with more time to perfect it than the others, having arrived first, it does not exploit this advantage and this excellent research and development work at all, to produce its Microprocessors? I honestly can't understand... So much investment money for what I wonder...
