Qualcomm has been discussing purchasing IFS for some time now, and they are also interested in buying ProdCo, so they still see value in both sides of the business.
They have not been able to get the Board to agree to any deal, so now make noise like they were not really serious before or something.
As far as x86, AMD claims that whatever energy efficiency advantage ARM once had has been erased over the past few years as x86 made changes to the architecture. Likely the increased use of different types of cores is also a factor. This was a bit of a surprise to me, because I thought x86 was being outperformed by ARM, but that is no longer true. I see its main drawback being the lack of licensing and the company has talked about selling more licenses but so far no action has been taken that I'm aware of.
The posters on this site have hate for Intel and x86, and even make up lies about layoffs and hiring, so are of no merit.
