There are a lot of AMD-related rumours doing the rounds today, the first of which concerns the potential emergence of Polaris 30 chips. The leak comes from Chiphell user WJM47196, who has a history of accurate AMD-related leaks, but grab a good fistful of salt and all that.

We’ve heard nothing about Polaris 30 before, but nor did we hear about Polaris 20 before the eventual Radeon RX 500 series arrived to replace the Polaris 10 Radeon RX 400 graphics cards. It would seem logical then that AMD would plan to launch a Radeon RX 600 series at some point either later this year or in 2019, and the easiest route to achieve this would be a refresh of Polaris.

Specifically, the Polaris 30 GPU would be the third iteration of the Polaris line, this time utilising the latest 12nm FinFET fabrication process. The leak asserts that there will be a roughly 15% increase in performance in comparison to 2017’s Polaris 20 GPUs. That’s not huge, obviously, but it’s a decent incremental upgrade for those looking at low to mid-range graphics cards.

In terms of the release window, the touted target is Q4 2018, making a holiday release for the Radeon RX 600 series.

We haven’t heard even so much as a peep out of AMD to confirm that this is true. Polaris 30 isn’t on any roadmaps and all we’ve really been hearing are rumours regarding 7nm Navi. Despite this though, AMD probably does need a stopgap until the expected 2019 launch for Navi, and the Radeon RX 600 series may fill that slot nicely. It wouldn’t be the most glamorous graphics card family launch, but it would certainly put AMD in pole position in like-for-like graphics cards compared to Nvidia, at least in the short term.
