Do you seriously think that an Intel monopoly on server CPUs is a good position for IBM to be in, whether strategically (control over platforms, programming models etc.) or purely economically (prices of Intel CPUs that go into IBM x86 servers)? That the RISC CPU market is shrinking (albeit with POWER growing its market share at the expense of IPF and SPARC) is a fact and has been for years, leaving System z as the only hardware platform controlled by IBM.That would be a stupidest possible move for IBM. Any large seller of x86 servers would have to be an idiot to tie themselves to AMD. IBM has no personal computer business. Their only x86 product is in the server space. Where did you get the idea that IBM partnering with AMD would make any sense at all? Wow.
They could then either be tied to AMD, and sell only AMD servers, letting them compete for the tiny server space (we're talking 5-8%?) that AMD is purchased in, or they could be tied to AMD, and still sell Intel servers. Which of those make sense? To me, neither.
I don't believe for a second that AMD in its present state can make competitive server CPUs again, however with IBM in on the design process more directly and more involved than before things would look a bit different. The legal implications of such an arrangement are a bit unclear however, and the business reasonings of IBM are another hurdle to that ever happening.
Edit: I do seem to recall though that IBM holds an x86 license from the days of the IBM PC.
