For the really competent watchers (The glyph and the dar...eh...the not that one. Any others? - There will be a quiz...):
Lunar Lake returns to a more conventional-looking design for Intel.

pibbuR after reading it considers himself semi competent. And who drops the quiz.
I don't know. They keep talking about a die, so I suppose it's enhanced to play D&D?
Very interesting! That's a bold design, with a lot of changes and a lot of redundancy to be more power-efficient for laptops - I wonder what the server CPUs'll be like.
The P and E cores smell like ARM's big.LITTLE, which has been out for years. A set of energy-efficient CPUs when not too much computation power is required, and another hungry set for high performances, though they removed hyperthreading and massively increased the out-of-order execution pipelines (which is an absolute nightmare to design). By the way, I wonder if that won't be more dependent on the compiler to achieve good performance.
And they did the same with the AI capabilities, by augmenting the hungry GPU cores with a dedicated NPU cores (still, much more powerful than the previous iteration). Is AI really so influential in CPU design? I think they may have overdone it, but that's just me.
The result is this huge monster, full of cores and full of caches, with mixed technology nodes. All that's missing is their new backside power technology.
I'm amazed one company could achieve something like that, and I really wonder how they design and validate the whole architecture. They must have tools and techniques that are far more advanced than what us mere mortals use.
