Laptop Logic have obtained inside info regarding one of NVIDIA's current projects in their secret lab, they're apparently working on a new form of SLI tech for notebooks which will be far more friendly in terms of power usage, however perhaps at the slight expense of performance (which you would expect is only the case when the system is running off battery power, not the mains).

The DailyTech have the scoop.

According to sources close to the company, NVIDIA is working on a new kind of SLI technology for notebook designs. Instead of pairing two identical GPUs for increased performance, NVIDIA is going for a pairing of integrated and discrete GPUs for a balance of power and performance.

The concept of pairing up a low-power integrated GPU with a high-power discrete GPU is nothing new. Sony has already treaded through these waters with its VAIO SZ lineup which features Intel GMA950 and NVIDIA GeForce Go 7400 GPUs.
