A new product page on Lenovo's website reveals the Legion Y530 and Legion Y7000P series laptops will feature the NVIDIA GeForce GTX 1160 and other next-generation GPUs. The page confirms the GeForce GTX 1160 will be offered in 3GB and 6GB memory configurations.
VideoCardz says this mobile card is expected to be introduced in early 2019. The GTX 1160 is believed to be a Turing-based model with no Ray Tracing cores. It's not known whether the chip lacks these cores, or whether they're just deactivated.
