Radeon RX 500X graphics cards will only be available to makers of laptops and prebuilt desktops, but don’t let that bother you.
“There are no hardware differences to non-X [RX 500 GPUs],” an AMD spokesperson told me. “The Radeon RX 500X series graphics cards is a brand refresh for 2018 OEM platforms that ensures Radeon RX 500 series cards are using the latest ‘Polaris’ architecture-based hardware and driver revisions (Radeon Software Adrenalin Edition) for 2018.”
Both AMD and Nvidia sometimes rebrand existing graphics cards when there’s a long dry spell between new GPU generations so that laptop and desktop makers have the “latest” hardware to sell inside their PCs. Fresh Intel 8th-gen laptop and desktop processors just became available, and another generation of Ryzen desktop processors is scheduled to launch this month. These rebranded GPUs exist so that PC makers can market “new” graphics cards in systems with those genuinely new CPUs.

Again, don’t expect to see discrete Radeon RX 500X graphics cards on store shelves. As AMD’s spokesperson said, this is a pure branding play for PC vendors, and an opportunity for those manufacturers to market all the truly killer new features in Radeon Software Adrenalin Edition. If you already have a PC with Radeon graphics inside, be sure to swing by AMD’s download page to pick it up.
Rival Nvidia is expected to release new graphics cards based on its Volta GPU architecture sometime this year, but the arrival of yet another Polaris refresh seemingly dumps cold water on any hopes of a Radeon response to the threat. The graphics architecture roadmap that AMD unveiled at CES 2018 didn’t show any new GPUs in the pipeline for this year except for a version of Vega built on the 7nm process node for machine learning customers.
