Another interesting slide in the deck showed an AMD Polaris 11 equipped laptop. The HP Omen, pictured below, represents "Console Class GPU Performance In Incredible Form Factors," according to AMD. Overwatch players can enjoy the game at 1080p Ultra with 1.2x performance compared to using a GTX 960M GPU according to AMD labs tests.
The AMD endnotes reveal that "The AMD GPU-based notebook is publicly available and featured an Intel Core i5-6300HQ, 2x4GB DDR4-2133, Radeon RX 460 graphics, Driver 16.20.1029, Windows 10. The NV GPU-based notebook is also publicly available and featured an Intel Core i7-6700HQ, 2x8 GB DDR4 2400, NVIDIA GTX 960m graphics, Driver 368.69, Windows 10. PC Manufacturers may vary configurations yielding different results. Overwatch was tested at 1080p, ultra settings. The Radeon RX 460 scored 62 fps. The GTX 960m scored 52 fps. Performance may vary based on use of latest drivers."
