Intel To Ditch Hyper-Threading For Arrow Lake?
Intel To Ditch Hyper-Threading For Arrow Lake?
Intel’s Hyper-Threading (and AMD’s equivalent Simultaneous Multi-threading, or SMT) technology is ubiquitous with any modern x86-based CPU, which gives them the additional ability to process two tasks simultaneously and boost multi-core performance. However, it looks like Team Blue is going to jettison that feature off come next generation.
The technology dates back to 2002 – when Intel’s Xeon server chips were the first to feature this technology. It took several more years before consumer hardware in the form of Core i7 (Nehalem, debuted in late 2008) gained the ability, but it has since been not available to the E-cores that Intel has introduced since Alder Lake (12th Gen) CPUs. From this point on, only P-cores have Hyper-Threading capabilities.
Previously, @YuuKi_AnS revealed the core layout of the Arrow Lake architecture, which consists of 8P+16E, 6P+16E, and 6P+8E configurations. However, further leaks from @InstaLaX64 have pointed out that these CPUs will not feature Hyper-Threading. The command line interface reads “Allowing 24 CPUs (logical processors)”, which means P-cores either have their HT disabled or were simply not present.
Meanwhile, over at Team Red, AMD’s Ryzen 7040 “Phoenix 2” processors took a different design approach, and all of its Zen 4 and Zen 4c cores come with SMT capabilities. It’s unclear if Intel’s decision may sway AMD into designing an SMT-less architecture in the future, as it is said that the lack of HT/SMT helps with closing off some of the chip-level attack vectors.

Pokdepinion: Wonder if that’s going to affect the multicore performance, and if Intel thinks this is worth the bet.
