In the old days when enthusiasts wanted to get more performance by overclocking, it meant sacrificing energy efficiency by bumping up voltage to stabilize higher frequencies. The higher energy draw inevitably increased heat and fan noise. When they wanted a quiet system that consumed less energy, they had to manually adjust the BIOS settings to reduce the frequency as well as the voltage. Each time users wanted to revert to higher performance, a reboot was required, making dynamic usage at optimum settings troublesome and unworkable.
ASUS has addressed this issue with the first Dual Intelligent Processor motherboards. These motherboards introduce two unique onboard processors that ensure optimized performance and power consumption. ASUS’ TurboV Processing Unit (TPU) accelerates your system performance by up to 37%, while the Energy Processing unit (EPU) saves up to 80% more power. Best of all, switching settings occurs seamlessly and automatically, leaving the enthusiast to enjoy his entertainment or be productive.

ASUS-exclusive Dual Intelligent Processors Motherboards Deliver a Perfect Harmony of High Performance and Energy Savings

ASUS, the global motherboard leader, has announced a new approach to motherboard design, Dual Intelligent Processors,
with two intelligent co-processors responsible for system optimization towards better performance and greater energy efficiency.

This cutting edge architecture comprises the TurboV Processing Unit, or TPU, and Energy Processing Unit, or EPU.
Together they help users benefit from extreme system performance while still conserving the environment by reducing a PC's ultimate carbon foot print.

The co-processors address the two prime issues behind PC hardware evolution-performance and energy efficiency.
As CPU makers strive to reach ever higher core counts and 32nm fabrication, this technology from ASUS promotes system optimization,
utilizing smart design to enable performance while at the same time saving energy.
It presents an effective way to get more out of existing PC hardware.

Performance Processing Unit for Significant Acceleration

The TPU consists of a complete overhaul of ASUS' extant TurboV design, presenting a support processing unit dedicated to speeding up performance in real time while monitoring gains to ensure stability.
The TPU relieves much of the stress put on the CPU during intense tasks, tuning overall resources to achieve the fastest performance possible.
The TPU supports various ASUS-exclusive performance tweaking innovations, and this auto tuning feature quickly finds optimized system settings to boost output up to 37%.

"Delivering amazing performance requires considerable finesse, especially in a user-friendly manner.
ASUS TPU technology makes that possible.
While manual system tuning calls for expertise and has too many variables that can go wrong,
the TPU helps users gain hassle-free improvements so they can enjoy and do more on their PCs", said Joe Hsieh, General Manager of the ASUS Motherboard Business Unit.

Major Savings on Demand

The ASUS proprietary EPU, or Energy Processing Unit, comes in as the second of the Dual Intelligent Processors.
It monitors and moderates power consumption, helping users save energy and ultimately lower their carbon emissions.
EPU programming keeps close watch on actual usage, reducing consumption during low intensity activities and opening up processing capabilities when needed.
When engaged in web browsing, word processing and office activities, this translates into major savings for most users.
Performance mode engages automatically on demand, so there's never any lag involved.

ASUS Dual Intelligent Processors technology is available on a full range of motherboards.

LOL these sorta features would prolly be disabled when you go for a high oc I think. Im not sure but I think the newer gigabyte bioses allow you to setup OC in steps with individual volts for each step as well. So when the pc is idling it will downclock to a preset speed with lower volts, I think UD5 and higher boards have this option.
 
^^ Nope.

On the p5q deluxe it did not do the needful (then again my experiences were with older EPU software) once you set the OCs on bios but on the newer ones it works like a charm.

This is with EPU disabled:

And this is with EPU enabled:

It reduces the clock speed, but yeah the point is even when overclocked manually, EPU is not disabled. Clock speed increases alongwith the load.

TPU helps you to tweak frequency and voltages :).
 
Thats quite nice, I wish my Gigabyte UD2H board had something automatic like that .....

On the bright side, manual mode works well enough with Gigabyte EasyTune6 utility. Just load up EasyTune6 (it comes with the MB Utility disc), hit Tuner and click Advanced. Then lower the Ratio to whatever you like and hit SET.

3.4Ghz to 1.2Ghz in 5 seconds :p
 
From what i understand,

EPU (Energy Processing Unit) provides total system power management in real time.

TPU (TurboV Processing Unit) auto-accelerates the system to optimised and stable settings without accupying cpu resources.

These are co-processors dedicated to their respective duties, providing overclocking and power saving on demand.

Afaik, hardware implementation is prefered always.

We have softwares to take care of certain tasks due to the lack of dedicated hardware for the same.

But as it is with software implementations, it occupies cpu resources and instability/bad performance is a possibility.
 
Good to have Asus come out with logics processors on their boards. The Gigabyte P35/P45 (early 2008) boards I had chance to play with, did energy saving (not sure if it was real time :p) when DES was enabled no matter overclocked or not, so nothing new but yes, Asus having sorted issues of energy saving when processor is overclocked, is good news for Asus users.
 
I have two questions for anyone who can answer:

Q1: What specific pieces of hardware does the EPU/TPU interface with? Is it only core components, or do PCI and USB peripherals also clock/power down and up?

Q2: How does this, if at all, work in tandem with Windows Power Management and other installed software such as RMClock, Speedfan, Rivatuner, CCC/nVCPL, Overdrive etc, which also access hardware registers directly to access and modify performance?

They are nice marketing terms, but a bit more in-depth information is preferred when it comes to a tech forum.
