As part of today’s GeForce RTX SUPER/Max-Q laptop announcement, NVIDIA revealed that Lenovo’s new Legion 7i and 5i would be two of the first notebooks to feature the latest version of its battery-saving technology, Optimus. The new iteration – dubbed “Advanced Optimus” – adds G-SYNC support and ensures long-lasting battery life by automatically switching between the discrete GeForce GPU and iGPU based on workload.

Our breakthroughs don’t just give you more FPS per watt. Our new Advanced Optimus Technology enables G-SYNC support for the first time, to deliver the long battery life we expect from Optimus, and the immersive, tear-free, stutter-free gameplay from G-SYNC.

This new groundbreaking display innovation dynamically selects whether the GeForce GPU or the laptop’s iGPU is driving the laptop display depending on what type of application you’re running. Obviously, you’ll want to have your GeForce GPU drive the display while you’re playing games, and with Advanced Optimus Technology, your laptop will automatically switch over to the iGPU driving the display while you’re browsing the web and watching videos to conserve battery life. Lenovo’s brand new Legion 7i and Legion 5i gaming laptops are the first laptops to offer this groundbreaking feature.

NVIDIA says that its DLSS and BatteryBoost technologies will also contribute greatly to battery life, extending use by as much as 20 percent. The latter “regulates the performance of highly efficient GeForce graphics cards to provide just the right amount of power to deliver that smooth gaming experience gamers demand.”


Another breakthrough is the use of NVIDIA DLSS to extend battery life while gaming. Powered by dedicated AI processors on GeForce RTX GPUs called Tensor Cores, DLSS is a deep learning neural network that boosts frame rates while generating beautiful, crisp game images. When combined with NVIDIA BatteryBoost technology, DLSS allows the GPU to operate in an ultra-efficient mode that delivers the same great experience but with up to 20% longer battery life while gaming.
