    Reverse-Hyperthreading from AMD coming soon

    http://www.bit-tech.net/news/2006/04...yperthreading/

    Basically using both cores of your Dual-core proc like it was 1 virtual core. I heard Intel is already working on this, too. Hope mit helps against Conroe

    Hey, thats actually genius...

    Programming would can stay the same, and yet we will actually see a DOUBLING of CPU power because everything is treated in succession instead of parallel...

    Never thought of it that way...damn...

    Looks like I'm starting to regret my X2 purchase...

    That is assuming that the results are as amazing as the idea...

    great idea, but we have to see the benchmarks first though.

    honestly this is an odd move instead of keeping the stress on the programmers to start coding to mutliple threads they are trying to achieve this in hardware. i dont think it will ever work as well as just writing code properly but its somthing

    Hmm. Anti-timeslicing. Instead of multiple apps getting chunks of time on one CPU, you've got one app spread over 2 CPUs. I'm very used to thinking in the other direction, so the feasibility here doesn't seem great.

    If successful, it would let single threaded cpu-hungry apps survive longer. But to satisfy both multi-threaded and single-threade apps, you'd have to be able to enable/disable without rebooting and changing the BIOS like hyperthreading.

    One more thing now that I think more -- this will only work at all if it's transparent to the application. If we would need to recompile Excel to take advantage of the architecture, it'll die still-born.

    good idea but will it materalize? Even if it does, Intel can do that with conroe and crush amd

    It may be patented, but there are ways around those. Plus, AMD doesn't have HT because they don't need it (shorter pipelines) not because Intel got a patent.

    I agree that Intel may be interested in this too, but I'm not sure why they'd "crush" AMD with it...

    I think Tbird has decided to get off the AMD fanboy thing now, Conroe is his new beast.

    I am curious about this too, now, if they made they SMP compatible, holy freakin' smokes................

    Sounds a lot like Intel's speculative threading "Mitosis" project.

    That's a pretty good idea. I'm surprised it wasn't thought of earlier. It's like SLI for CPU's.
