There's more evidence that Arrow Lake-S CPUs might not have Hyper-Threading. Following previously leaked slides, an entry on Intel test machines with an undisclosed Arrow Lake CPU with 24 cores and 24 threads has been found.

Hyper-Threading is a multithreading technique that enables physical cores in Intel CPUs to accomplish two tasks simultaneously, thus serving as two logical cores. The technology was launched over 20 years ago on Xeon HEDT CPUs. Eventually, the technology found its way onto the mainstream market via the Core series. For over 15 years, Intel Core processors have had this technology, but things are about to change with the upcoming Core Ultra Arrow Lake processors.

I spotted a new #ArrowLake-S (CPUID C0660, 24 threads, 3GHz, w/o #AVX512) among the #Intel test machines:https://t.co/xiSjhpEcPP https://t.co/X7iBnRq9gW pic.twitter.com/Dasjo0L6Fp

According to the Arrow Lake-S CPU spotted by InstLatX64, the upcoming processor series won't feature Hyper-Threading. With 8 P-cores and 16 E-cores, a CPU with Hyper-Threading should have 32 threads, with the 8 P-cores having two threads per core. However, that's not the case, as it shows the chip has 24 threads, making one thread per core and, therefore, no Hyper-Threading.

Moreover, the listing also states that the current engineering prototype operates at 3GHz and does not support AVX512 instructions. Intel Arrow Lake-S processors are expected to be released later this year.

KitGuru says: Dropping Hyper Threading would be a significant change. If true, it will be interesting to see comparisons later in the year.
