Report: Intel Has Incorporated Reverse Hyper Threading Into Skylake CPUs

According to a new report that has surfaced, the recently released Intel Skylake CPUs have a few feature in them known as Reverse Hyper Threading, which is a fancy way of saying it boosts single-threaded performance. The Reverse Hyper Threading combines the performance of multiple cores on the CPU into a single virtual core, improving performance on single-threaded workloads.

The reports come from performance testing at Heise, who have noticed the Intel Core i7-6700K CPU registers significantly faster single-thread performance in the SPEC CPU2006- Suite Computational Fluid Dynamics (470.lbm) benchmark . The Core i7-6700K clocks in at 2.4 times faster in single-thread mode than the Haswell-based Core i7-4790K which preceded it.



The Reverse Hyper Threading works by utilising a secondary central processing unit core to assist with the first, for caching, buffering, etc. This process stacks as well, so a virtual core can be composed of several physical cores to form a hugely powerful single core.

Benefits to gaming could be fantastic with Reverse Hyper Threading. Many games are typically poorly optimised for multi-threaded performance, and creating virtual super cores will improve certain games immensely.

At the moment this is all just conjecture, but based on the evidence we’re seeing so far, this looks to be the case with Skylake. Despite the fact the new microarchitecture is already on store shelves, we still know precious little about how it actually works. Intel has announced plans to reveal more details about Skylake during the Intel Developer Forum 2015 ( IDF15), which runs from today through until Thursday, 20th August.
