Yeah, the Prescott P4s and the dual-core P4s were both extremely good at being space heaters while also being extremely bad at being a CPU.
The whole P4 era was a suckfest for Intel, and they didn’t really shake the slow, hot, power hungry thing until Sandy Bridge (so basically 2000 to 2011 ish). And before anyone mentions them, Core/Core 2 were MUCH more performant and certainly better performance-per-watt than the X2/X4 Athlons, but still not particularly efficient in comparison to Sandy Bridge and later.
I’d also argue Bulldozer wasn’t necessarily a bad uArch, but it just had a couple of poor design decisions that made sense historically but did not really work in practice, and had fucking awful timing going up against Sandy Bridge, which was fucking excellent.
