bit-tech reader RotoSequence writes to point out a very cool snippet of info over at French news site X86-Secret.

The info is about a potential new AMD processor. Allegedly, the green camp is developing a sort of "Anti-Hyperthreading," which would allow two (or multiple) physical cores to emulate one physical core.

From the site (via Google translation): "Conscious that K8 architecture could not compete with the next high-speed motorboat of INTEL, all its hopes are for the moment based on a new 'revolutionary' technology (it is our opinion, not it his) on which AMD works in this moment for after-K8. This technology is in fact a kind of anti-HT: There or HyperThreading sought to emulate two virtual processors with a physical processor, it is a question for AMD of emulating a single virtual processor with two (or several) physical processors."

This could be incredibly interesting. Early performance numbers suggest that AMD's new AM2 platform won't be able to compete with Conroe on raw native performance. However, if AMD can perfect the ability to make multiple cores appear as one, then it could take a massive performance lead in applications that are single-threaded - like the vast majority of games right now.

Is this cool, and is it even feasible? Let us know your thoughts over in the forums.
