[H] AMD and Reverse Hyperthreading

[Chris Reeves]

AMD’s AM2 boards have a neat little feature built in: reverse hyperthreading.  This will allow single-processor applications to see the two cores as 1 processor.  So, a dual core 2.2Ghz 4400+ would look like a single core, 4.4Ghz processor (6 IPCs compared to Conroe’s 4).  Interesting little trick.   http://www.theinquirer.net/?article=32589
