* Reverse Multithreading

PC Games/Hardware/Microsoft
An interesting concept from AMD - reverse multithreading, designed to let single-processor programs take advantage of multiple processor power:

Of course, better out-of-order execution techniques render HyperThreading - Intel's version of the simultaneous multi-threading (SMT) technique - less important. Put simply, they ensure there are fewer parts of the pipeline going unused at any given time, so there's less performance to be gained by throwing extra threads at the processor. Indeed, Intel's briefings on its next-generation architecture, due to debut in Q3 as the 'Conroe' chip, play down HyperThreading and talk up out-of-order execution.

But Conroe, so far as Intel is admitting, still appears as two CPUs to the host OS. So is there anything to be gained by making it appear as just one processor? Well, operating systems already do a good job of scheduling hundreds of threads on a single-core CPU let alone a dual- or quad-core part, and AMD may have found that OS is so good at this that it can make up for the apparent reduction in parallelism, particularly in cases where one thread predominates, in a game, for instance.
Still in the concept stages, but definitely worth a look.
