A bit of a blast from the past but didn't Samsung handle some of the large, high performance, high clock (for the time) DEC Alpha chips over a decade ago? Granted I can't think of anything that worked on 250 nm that'd translate well to 7 nm manufacturing but as a company they have had experience with such products.

I guess the real question is if POWER10 and z15 will come in a version as a large monolithic die or go the chiplet route. IBM already does this to a limited degree with zSeries with the L4 being a separate die and how they handle redundancy but implementing everything in a duplicate fashion. My guess would be that IBM will go with chiplets for POWER10 as a means to test the waters with 7 nm manufacturing. The zSeries traditionally has longer life cycle so that would give IBM time to test the viability of a chiplet design for the mainframe world that values reliability over performance.

There is also a political aspect to the zSeries as they are the core of several government systems and there is an incentive to keep them on a trusted foundry. This is a commercial product that isn't a true product that falls under the TFP but traditionally manufactured with such partners. There has recent scares of hardware exploits being inserted at the manufacturing stage and this may spur a formal change here. I don't know of a TFP fab that is has sub 14 nm on their roadmap in the US. In fact, I think only Intel has plans to go below 14 nm with fabs in the US and they are not TFP. While unlikely, I would put Intel in the running to manufacture the z15 chips for this reason.
