The real benefit will come soon when AMD will announce Reverse HT. Intel has gone the HT route, making two logical processors from one physical. AMD will go the other way - making one logical processor out of two physical ones. This might seem like a silly idea. However, most applications to-date are not optimized for multi-processor (multi-threaded) execution. Single-threaded applications make up at least 95% of all software. So in effect, Reverse HT will make any non-multi-threaded application believe there is only one processor and present one CPU with double the processing power. For this to work correctly, both cores have to be synchronized exactly or bad things will happen. Still, any multi-threaded application should also benefit from this driver in the current form.

Imho it looks more like a Patch/Fix than an optimiser. /Mav We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars. (Carl Sagan) ID: 357364 ·

How about this one, then? AMD and SUN to share a common CPU socket in 2008 - seems AMD is making a couple of key strategic moves right about now. Bears watching :o) Conroe is going to be way ahead in raw performance, but as far as platforms go? AMD is WAY ahead. There will not be close to enough Conroe MoBos out at launch...Intel chipsets are delayed, and only ATI is working on another chipset for it. Shoot your parters in the foot, pretty soon they stop being partners...(i.e. SiS, VIA,... they all used to make Intel compatible chipsets). It's going to be an interesting two or three years. We'll see what strategy pays off. Regards, Simon. Donate to SETI@Home via PayPal! Optimized SETI@Home apps + Information ID: 358724 ·

It was nice, but it won't happen (at least, not soon). Simon. Donate to SETI@Home via PayPal! Optimized SETI@Home apps + Information ID: 379647 ·
