Lenovo's Legion 5i and 7i gaming laptops include the exclusive Nvidia Advanced Optimus feature for extended battery life
Intel’s latest Comet Lake-H CPUs and the Nvidia RTX 2000 Super mobility GPUs will soon be included with Lenovo’s new Legion 5i and 7i gaming laptops. Even though the spec details are quite scarce for the time being, Lenovo does mention that these two models will benefit from an exclusive feature called Advanced Optimus developed in collaboration with Nvidia.
The Advanced Optimus algorithm can switch between iGPU and dGPU based on GPU workload. For light workloads like web browsing, productivity tasks and movie watching, the Advanced Optimus feature will switch to the iGPU, while the dGPU will be used only in 3D games and compute-intensive applications. This should preserve and extend battery life by a decent margin.
Both versions will feature G-Sync-compatible panels, however, there is no word on the exact refresh rates. The 7i is clearly the premium version and will pack RTX Super GPUs along with Core i7 CPUs, most likely. This model is also getting turquoise led lighting. On the other hand, the more affordable 5i is limited to RTX 2060 GPUs and will probably feature only Core i5 CPUs.
As far as prices are concerned, the 5i with an RTX 2060 GPU will sell for US$999 and will replace the Legion Y540, while the 7i equipped with an RTX 2070 will cost US$1,199 and will replace the Legion Y740 model.
