New Riva Tuner reveals hidden RV670 features
A NEW VERSION OF tweaking tool for owners of Nvidia Riva TNT GeForce and ATI Radeon cards has made an appearance over at Guru of 3D.
The new version brings support for tweaking the upcoming RV670 cards, but only the 3850 has been tested. This is vthe alue card with either 256 or 512MB of video memory. The 3870 should work as well.
Hardware monitoring module now properly detects DPM (Dynamic Power Management), a key feature of upcoming RV670 chips. Riva Tuner can monitor dynamically changing RV670 GPU and memory clock frequencies, adjusted in real-time.
As far as we know, RV670 chips will change their clock and power consumption according to 3D load. So, if you're running a highly demanding scene in a game, the GPU will be clocked at maximum, speed, while running cut-scenes or any lower-GPU intensive scene will cut down the clock of the card and decrease the power consumption.
This is something that Nvidia cannot offer with its GeForce 8800GT, at least according to Daamit's marketing slides.
Fixes in 2.06 version include DDR2 video memory detection on some 8500 and 8600 graphics cards, issues with UI and localization. What's more interesting is added support for ForceWare 167 and 169 series of drivers, but Unwinder warned about broken 2D/3D performance level switching. Good part is that owners of Radeon HD 2400 and 2600 can now enjoy expanded support for hardware tweaking, so you can squeeze a bit extra from those 65nm chips.
Pretty big improvement is the driver-level fan control tab on Windows Vista drivers. You can control the fan on mid-range Nvidia cards using direct NVAPI interface. µ

"This is vthe alue card with..."

How did your 'v' jump 4 places back ? Reminds me of a bash quote.
Getting tired of constant paper rubbish.

DAAMIT we wanna see the card in action and some becnhies!
I can´t deny it takes a lot of experience and knowledge to create such a tool.
But sorry I don´t think Unwinder is working for nvidia or ATI lol, sorry no !!!
Go visit guru3d forums, you can talk to the Creator of Rivatuner directly there in the forums.
It seems that Guru of 3D is having some technical difficulties atm, this is list of links that work:

...and even features of products that don't yet exist on the market ?
Either it's not written by guru3d.com staff and/or guru3d.com is owned by AMD/ATI and/or Nvidia. 
It's not that you can "discover", "find out", "guess" GPUs/chipset and hardware features. Whoever really is behind Rivatuner and writes the code must be someone among AMD/ATI and Nvidia developers and drivers coders in the first place. The is no guess trick and reverse engineering is not an option, guessing is not an option. You can't just find things out by chance, you need some proper detailed documentation directly from the manufacturer in order to write any tweaking application. 
It's amazing that Companies like Nvidia and ATI can get away with this an no one seems to notice nowadays, I mean.. recently there was a lot of fuss about some websites that was found out to be controlled and owned by some Sony employees and wanted to look amateurish, yet no one notices that tweaking applications like Rivatuner (and others.. like the various modified/modded Nvidia and ATI drivers available online...) can't be assembled by an amateur programmer and not even a pro if he/she doesn't have the proper official documentation directly from the manufacturer, at the very least. 
It's pretty clear that by releasing a tweaking application that is able to tweak not yet released hardware and has the ability to tweak unknown to the public hardware features, then it must be written or at the very least deeply co-written by employees of AMD/ATI and Nvidia directly. 
Without proper documentation you can be even the smartest designer or coder on planet Earth but you wan't be able to achieve anything serious.
This sounds like an OEM win to me. You have to ask yourself, "where is the money, from the average consumer or from OEM?"
