>>I have a 3-core processor. I just had to have it. Sounds like one of those engines with three cylinders. After ages of everything being 2**n, I now have something odd under the hood. And it works fine.

You mean this is like the 8K memories for the old Spectrum - actually 16K where one side didn't work so Sinclair got them really cheap? I.e. a quad core processor where one of the four doesn't work? Wouldn't be anything new - even to me. I wonder why is that, they lock one to have a processor which fits the price niche, or they are selling a series of quarter-faulty quads as trios?
