Intel suddenly abandoned technology on CPUs that existed for more than 20 years

 

Intel's fastest processors have included hyper-threading technology, a technique that allows multiple threads to run on a single CPU core, for more than 20 years.

However, hyper-threading technology, denoted by the inscription HT, will no longer exist on Intel stickers for any laptop CPU as Intel will disable it on all of its CPU cores. Lunar Lake, including high-performance and energy-efficient cores.

So why does Intel do it? The reasons are complex, but it's essentially fallen out of favor as Intel tries to maximize power efficiency in portable laptops. The high-performance cores, or P-Cores, on the new Lunar Lake series are 14% faster than the same cores on previous generation Meteor Lake CPUs, even with hyper-threading multi-threading disabled chemistry.

Enabling this feature consumes too much power, and Lunar Lake is only intended to increase performance while keeping laptops of this generation thin, light, and long-lasting. That means maximizing single-threaded performance will help improve overall performance per watt. Removing the physical components needed for hyper-threading only makes sense in that context, although it likely means that Lunar Lake CPUs won't perform as well as AMD-powered laptops in other environments. multi-threaded tasks.

The cores on Lunar Lake do not have "hyper-threading".

Previously, Intel also eliminated replaceable RAM on Lunar Lake laptops by integrating RAM on the processor to optimize energy usage. This is also another big change that Intel is aiming for CPUs in the future.

Even so, hyper-threading may still be available for desktop CPUs in the future, especially for applications that require high power such as server and data center processors, or even Even gaming laptops care more about raw power instead of energy savings.
