NVIDIA Corp., announces NVIDIA Optimus technology, a breakthrough for notebook PCs that chooses the best graphics processor for running a given application and automatically routes the workload to either an NVIDIA discrete GPU or Intel integrated graphics – delivering great performance while also providing great battery life.

“Consumers no longer have to choose whether they want great graphics performance or sustained battery life,” said Rene Haas, general manager of notebook products at NVIDIA. “NVIDIA Optimus gives them both - great performance, great battery life and it simply works.” Just as a Hybrid car chooses between the gas-powered and electric car engine on-the-fly and uses the most appropriate engine, NVIDIA Optimus technology does the same thing for graphics processors. NVIDIA Optimus Technology instantly directs the workload through the most efficient processor for the job, extending battery life by up to 2 times compared to similarly configured systems equipped with discrete graphics processors (GPUs). When playing 3D games, running videos, or using GPU compute applications the high-performance NVIDIA discrete GPU is used. When using basic applications, like web surfing or email, the integrated graphics processor is used. The result is long lasting battery life without sacrificing great graphics performance.

I dont think having 2 GPUs is very efficient, Why not just make a decent GPU that downclocks to IGP level when its not needed. That would be something to get excited about.

This is HybridPower version 2, but it works with Intel GPUs.

I have PowerXpress, switching between 4200 and 4570 whenever I like. Took Nvidia long enough to notice that.

Interesting, I have an old sony Z series laptop that does something similar to this. There's a switch just above the keyboard that either disables the nVidia graphics and enabled the onboard intel or vise versa.

It's there "stamina/performance" switch.

No need for a switch, it's all done on the fly as you "need" the Nvidia GPU if you believe the PR

Yea, Sony did do this with the switch. Sadly you had to reboot to enable the other GPU (not on-the-fly). IMO, I don't see the point to this. High-end mobile GPUs can already underclock and undervolt during low usage (powerplay and other technology).

But even when underclocked and undervolted, they still use a huge amount of power compared to a weaker card, and that will continue to be the case until they figure out how to completely turn off parts of the silicon, which I don't thing will be much longer.

if the intel uses 10W at load (desktop) and a G92 card can use upto 50W at idle... you get the idea for battery life. the bigger the GPU, the more this will help.


shit, i want this on desktops - i get ~250W of power draw from my two cards idling.

PowerPlay is an ATi tech, so nVidia can't use it and are trying to make a competitive technology with this.
I can tell you for one, that the PowerPlay on my 5850 drops it's GPU freq from my overclocked 775MHz down to 157MHz and the same for the OC'd GDDR5 at 1125MHz that drops to 300MHz in about 1-2secs of becoming idle, dropping the power draw by a magnitude of almost 10!
nVidia realise, I think, that in the face of this (and the concern for the environment by most potential consumers), considering that they're making another monolithic GPU with the GF100 which will no doubt draw some crazy power, that they need to reassure everyone that once 10+ people switch on their GF100 rigged PCs, it won't cause a global blackout.:laugh:
