Looking at the technology, and how they would accomplish it, there is no need to deny that it could be done. Its not hard to do at all, us regular users just never looked at it as an option. For all fairness, its been in R&D for many many years now.
Core Multiplexing is an option in the Intel "BadAxe" R.304 motherboard. Thats as much confirmation as I need, personally. It won't work as soon as you fire it up, you'd need a Windows patch and maybe a BIOS update. But its there, and I'll take it. You guys, ofcourse, are free to believe whatever you wish.
From what I understand, RHT/CMP are different concepts. I personally believe the CMP is real, as there is hard proof of it. But RHT has a lot of "rumor proof" around it. Such as people overhearing AMD engineers talking about it, etc. I do hope its as easy to implement as The Inquirer says. After you seperate fact from fiction, L'Inq is an exceptionally useful website.
