Dell going to use AMD I'm sure I've heard that one before.
Sounds like a negotiating ploy to get Intel to cut them a discount.
No they clearly already have a deal with Intel, but they are trying to make it not as obvious. Dell's website only has AMD cpus in their lower tier consumer products, and you still have to specifically filter for AMD. They offer them in a way that if someone suggests similar collusion as before, they can say "no we sell them, see". AMD has been a premium choice for several generations now, but putting them on the roadmap for 2027 is really just the window for which Intel hopes to recover. They are offering Qualcomm as an XPS option immediately for example.
Another example is that VMWare was owned by Dell when AMD Epyc CPUs were released, with double the core counts, better performance and lower cost, than Xeons. Basically overnight the VMware licensing model changed to a per-core model that would make using Epyc way more expensive.
