In April of 2006 information surfaced at the French hardware site x86-secret which claimed that AMD is working on a technology it calls reversed HyperThreading. We wrote the following in out first news post about AMD’s reversed HyperThreading technology; “AMD’s idea is to turn it all upside-down and get a processor with dual cores simulate a single core processor. It would simply mean that the power of two cores could be utilized by single core programs, which in theory would lead to twice the performance with single-threaded applcations.” This information caused quite a lot of discussion around the web and now X-bit Labs has dropped the next bomb. According to their sources AMD has already developed the technology and integrated it into today’s Socket AM2 processors. The technology only requires a BIOS update and a patch for Windows, which lets the computer recognize the processor as a single-core processor instead of a dual-core processor. The reversed HyperThreading technology will dynamically shift between its dual/singel-core modes to optimize the performance at different loads. “According to sources and alleged preliminary test results, the CPU will be able to switch into this “combined” mode dynamically, depending on the type of the application. There is no secret that a lot of tasks still benefit from single-core CPUs more than they would from the dual-core processors working at lower nominal frequencies.” According to this information AMD is aiming to introduce this technology within a month as Intel will launch its Core 2 processor (Conroe) for the stationary market. We are truly looking forward to hearing more about AMD’s reversed HyperThreading, but if the technology arrives within a month few will be surprised.
