It seems like AMD’s Radeon RX Vega 64 has major on going supply issues as two manufacturers have backed out from offering any custom variants of the GPU at all. The report posted by Toms hardware indicates that MSI and Gigabyte will not be offering any custom Radeon RX Vega 64 GPU but instead focus on the NVIDIA GeForce GTX 1070 Ti which will be out in October.

It looks like AMD’s AIB partners have been waiting for the team red to sort out their supply issues for so long that they simply aren’t planing to offer any custom boards at all. Tomshardware report indicates that the reason behind all of this has to do with the cost and availability of the packages. The GPU packages are also said t be very fragile so the RMA rate could turn out to be really high as there will be a potential mining market going after these GPUs as soon as they launch.
