Below is a link to an article which fully explains hyperthreading technology and it's benefits. After reading the article even a novice like myself can see how chess programs will benefit from the technology significantly. There is far more involved here than merely getting an extra thread or two for your program. Hyperthreading also fills in the data "holes" as the processed information passes through the Front Side Bus. This results in up to a 50% increase in the amount of work being done by the cpu's. The technology is not a "hoax" designed to merely create virtual processors to "trick" your program. Since Chess engines are resource hungry and tend to use 100% of the available cpu processing power, it only makes sense to put the front side bus to work and make it earn it's keep. Especially if it is a 533FSB chipset we are talking about. It is clear from this article that hyperthreading is the single most important advancement in CPU Technology in recent years. Yes, the Intel Processor's are expensive; Yes the AMD gives more performance for the dollar; but no the AMD will not perform better overall than the New generation Xeon processors utilizing hyperthreading technology and anyone who fully understands the technology, or owns both systems, would not claim otherwise. Intel spends more money in research and development per year than AMD's entire annual budget so naturally their processors are going to be more expensive. While AMD has been striving to design processors that simply faster, Intel has been looking at ways to make them faster AND more efficient and their research has now come to fruition. Below is a link to a detailed technical artice which explains the technology for any who are interested. it was a very fascinating article and I highly recommend it: http://arstechnica.com/paedia/h/hyperthreading/hyperthreading-1.html
