Intel Arrow Lake-S May Rethink Hyper-threading Approach

Rumors have surfaced that the upcoming Intel Arrow Lake-S desktop CPUs may lack hyper-threading and AVX512 instruction support. The leak came from InstaLatX64, who spotted a 24 core and 24 thread Intel Arrow Lake-S CPU sample running at 3 GHz on an Intel test machine.

Unlike previous generations where Intel actively utilized hyper-threading, the new Arrow Lake-S series is speculated to offer processors featuring the Lion Cove P-Core and Skymont E-Core architecture, including up to 8 P-cores and 16 E-cores without doubling the threads for each core. Intel's decision might be driven by several factors, including optimization for modern workloads and simplification of the architecture amid an increase in the number of physical cores.

It was also revealed that Arrow Lake-S CPUs might exclude AVX512 support, likely due to Intel's intention to limit these instructions to the server and corporate segments due to their high power consumption. Instead, Intel will introduce AVX10 ISA support, promising improved functionality.

The new chips will be built on the Lion Cove P-Core and Skymont E-Core architecture, offering up to 24 cores. Alongside, the latest GT1 Xe-LPG iGPU with a reduced number of Xe-cores compared to Meteor Lake CPUs is expected. Arrow Lake-S CPUs will be released on new motherboards featuring the LGA 1851 socket and the 800-series PCH, including Z890, H870, B860, and H810.

These changes highlight Intel's efforts to adapt its technologies to meet current and future market demands, while offering users alternative solutions in terms of performance and energy efficiency.
