leaked slide from internal presentation confirms plans to showcase the new series on September 27th. Intel will start preorder campaign for its flagship Core i9 series immediately, to be followed by Core i7 and Core i5 series two weeks later. None of those CPUs will become available until October 20th, so almost a month after AMD officially launches its 7000 series. When it comes to Z790 motherboards, one should also expect the sale embargo to lift on the same day all three Core series become available.
