TSMC accidentally destroyed $550 million worth of wafers due to a manufacturing defect. Nvidia GPUs and Huawei SoCs are also affected.
AMD is updating its entire product range this year. Ryzen 3000, the chipset X570 with PCIe 4.0 and Radeon Navi will be released on July 7th.
Navi is the next generation of AMD graphics cards. It should actually come onto the market in the third quarter of 2019, but appears to be delayed.
