>But this change is "forever" and not just for this case where we get a new very different arch together with a refresh.
Right, it's not about the architecture, but the beefed-up iGPU (more precisely, tiled GPU or tGPU) and AI that comes with chiplets. Even when MTL is superceded, the good-vs-adequate iGPU differentiation will remain, and will be the heart of the Ultra (premium) brand.
The AI accel isn't a big deal for now, functionally speaking. But given the ongoing AI craze, it makes for another selling point. I'd expect CPU-based AI will factor more heavily going forward, with Microsoft going all-in with generative-AI "copilots" in future Win iterations.
>Since they are retiring the celeron and pentium names for all we know the normal non-ultra CPUs will be the celeron, and pentium silver and gold, those are three tiers of CPUs that could be core 3, 5, and 7, and what was the core i tiers will be the core ultra tiers.
As the Verge piece states, there'll be 3 main segments, Intel (low-end), Intel Core (mainstream), and Intel Core Ultra (premium). Previous Pentium/Celeron parts are now just Intel, eg Intel N200 CPU.
>So basically everything will be the same for the main lineup, just substitute the i with an u, and the cheapo CPUs will now be more in line with the general naming scheme.
Ultra = better iGPU + AI + best speed + whatever new tech down the road. Low-end is just "Intel". It's the Core (mainstream) parts that are unchanged.
Having K parts separate from the Ultra brand will bring added complexity. My prediction is that K will be folded into the Ultra segment, leaving non-K parts in the Core segment.
