According to a recent leak, a new device listed as “AMD Steam Machine” has officially appeared in the Vulkan product database from the Khronos Group. This confirms that Valve’s expected system has passed the strict Vulkan API conformity tests (CTS 1.4.5.3).
The registration, submitted on May 23, 2026 under the Software Freedom Conservancy organization, reveals several interesting details about the hardware inside the machine.
Valve’s New Steam Machine Leaks With Custom AMD Hardware
On the graphics side, the device uses the open-source Mesa/RADV driver stack for Linux and identifies the GPU family with the codename “RADV_NAVI33.” This confirms the use of a graphics architecture based on AMD’s Navi 33 chips, which are built on RDNA 3.
The main processor is described in the leak as “AMD Custom CPU 1772,” suggesting that AMD and Valve developed a custom chip specifically optimized for the Steam Machine.
As for the operating system, the test setup was running on the internal branch “Linux 6.16.12-valve6-1-neptune,” the name Valve uses for the core of its software layer focused on consoles and gaming platforms.
Although appearing in Khronos Group listings does not reveal an exact launch date, in the hardware industry this step is usually considered one of the final legal and technical processes before an official announcement.
With the Steam Machine passing Vulkan 1.4 certification, Valve could now be close to officially launching the product, which many PC players have been waiting for.
