Intel Hyper Threading

Intel's technology allows one physical core to function as two logical cores. (The corresponding technology in AMD is called SMT.)

However, it was revealed that Intel's Hyper-Threading is a bundle of security vulnerabilities (L1TF bug, ZombieLoad bug, etc.), which made it sound like hyper-trash again. It has been somewhat patched from the R0 stepping deployed since April 2019, but it is still just a makeshift measure. For reference, this vulnerability does not exist in Ryzen's bidirectional SMT. So it is missing from Lunar Lake.

Intel abandons hyperthreading for Lunar Lake CPUs

The thin-and-light laptops with Intel's new Lunar Lake CPUs won't have - or need - hyperthreading, a technological mainstay for 20 years.
