AMD has just announced that its next-generation RDNA2 based Radeon RX GPU family will feature 50% better performance per watt than existing RDNA based gaming graphics cards. The new GPUs would also feature additional features which would deliver better gaming experience while being based on the latest 7nm+ process node.

AMD unveiled that its RDNA2 GPUs will deliver a similar performance jump over the first-gen RDNA GPUs like Zen 2 delivered over Zen 1. The first RDNA GPUs delivered a massive 50% increase in performance per watt over GCN architecture and RDNA2 GPUs are expected to do the same over RDNA1, delivering another 50% increase in performance per watt. This increase isn't specific to just desktop parts but would also be seen in the notebook segment as mobility chips based on the 2nd Gen RDNA architecture would also be landing in gaming notebooks at the start of 2021.
