Intel Skylake CPUs Might Feature Reverse Hyperthreading to Enhance Single-Thread Performance
According to a new report, Intel Skylake CPUs might have a new feature called Reverse Hyper Threading which boosts single-threaded performance. To put it in simpler term; the feature combines performance of multiple physical cores into a single virtual core.
German website Heise reported unusual behavior demonstrated by Core i7 6700-K CPU while testing with the SPEC CPU-2006 Suite. The site reports finding the single-thread performance of Core i7 6700-K to be 2.4x faster than the Core i7 4790-K. Furthermore, the different was a lot less when multiple cores and threads were tested – about 20% with multiple-threads and 170% with single-thread.
The report reads that Intel might have added a new feature to the Skylake CPU which allows a secondary core to assist the first core with cache, buffers, or additional functional units. Basically, a single virtual core made up of several physical cores.
However, do note that the entire thing is speculated by a single website and should be taken with a grain of salt. We are expected to learn more about the Intel Skylake Processors at the Intel Developer Forum which is scheduled to take place on Aug. 18, 2015.
