right, i was reading something about conroe on another thread and someone mentioned a 'reverse' version of hyper-threading, so i did some looking around on google and came up with a few results, im shocked that nobody has given this any welcome or thought at all, someone even said its pointless, that its a step backwards? i think this reverse HT could be one of the best ideas AMD has had, and im sorry but its far far from a step backwards, example. you and a friend are in class trying to solve a complicated physics calculation do you A) work together as a team and do it much faster and proberbly more accurately or B) one of you do it and the other sit and be a dunce? reverse HT basically intends to do this in a CPU (dual cores to be specific) that a dual core processor (where one core basically does sod all most of the time) could use both cores to run the same processes. sorry folks but thats gonna give an utterly staggering increase in dual-core processor performance in single threaded applications, and theres no reason this applies only to dual-core if you think about it, four processor cores running dual threaded application, two cores doing all the work, not with reverse HT. am i the only person in this entire forum who is interested by this, someone please tell me im not alone?

AMD Reverse Hyper-Threading...

thats totally what i was thinking, running single threaded applications through two cores would (in a perfect world) divide the workload evenly between the two cores, meaning you could get 100% increase in single threaded performance. that only works if you can successfully split the thread into two equal parts and process them and combine what comes out the other end, without harming the ability to do the exact same with multi-threaded apps. another thing is such technology might be able to work for more than just two cores, imagine how fast a quad core processor would run a single threaded app if the load could be shared equally amongst the four cores, this for me is the single thing making me personally not bother with a dual core processor at this time, since most apps are still single threaded, a single core processor runs things just as well as a dual. only because the other core is being wasted running background applications, AMD have this reverse HT, and intel have something called 'mitosis' i believe, i don't see hows its impossible, tricky but plausable IMO. i really hope intel or AMD can pull this off sooner rather than later and get it out to the market, the performance increase would be staggering if it worked as intended
