Lunar lake is x86-64 https://en.wikipedia.org/wiki/Lunar_Lake

Intel said that with Lunar Lake, it aimed to "bust the myth that [x86] can't be as efficient" as ARM.[3] Analysis of tests performed on Lunar Lake CPUs available at market launch indicated that, although their multi-core performance was not particularly good under full load, their efficiency under everyday use was good, even if the ARM competition still has its advantages.[4]

That was a joke 😂 I'm not seriously thinking they put ARM instructions in a x86 processor, though they might've tried to replicate the optimisations that led to less power usage in those RISC processors (I still can't get why RISC CPUs are more power efficient honestly, it seems counter intuitive, now again it might just be because of overengineering).
