Intel's next-generation processors, Lunar Lake and Arrow Lake, do not support the AVX-512 instruction set and have also dropped hyper-threading technology. In contrast, AMD's Zen5 continues to support multi-threading.

Does Intel's decision suggest that hyper-threading is no longer beneficial? How does AMD's retention of this technology impact performance?

Phoronix conducted specific tests to analyze the performance difference with the multi-threading technology on the Ryzen AI9HX370 switch. The operating system used was Ubuntu 24.04, and a total of 57 projects were run.

On average, enabling multi-threading technology on the Ryzen AI9HX370 improves performance by 18%. Certain projects, like the toyBrot Fractal Generator, show gains of up to 67%!

When it comes to power consumption, there is minimal difference between single-threaded and multi-threaded modes. The average power consumption with multi-threading turned off is 19.24W, while with multi-threading enabled, it is 19.63W—a difference of only 2%.

Temperature levels also remain constant.

Intel has not provided a clear explanation for eliminating hyper-threading technology. It may be due to the heterogeneous hybrid architecture like AVX-512, but Intel claims that removing hyper-threading from the P core can boost energy efficiency by 30%.
