AMD is planning to bring big competition in the mainstream and budget segment with their Navi ‘Radeon RX’ GPUs based on a report by PCGamesN. The report is based on a recent listing in the Mesa 3D GPU library which has tagged the addition of PCI IDs for two upcoming Navi GPUs, Navi 12 and Navi 14 as ‘trivial and urgent’.

The source reports that AMD’s open-source guru, Marek Olsak, has termed the addition of PCI-IDs for both unreleased Navi GPUs very urgent and if that is to go by anything, that means that we will see the support added by the next Mesa update which is version 19.2 which just recently landed. It looks like if AMD is planning to drop in support for this specific version then the launch of Radeon RX graphics cards based on the Navi 12 and Navi 14 GPUs may not be that far away. And since the new update (version 19.3) doesn’t land till 15th October, it only shows that the new Navi based line would be available before that.
