What the New Steam Machine Benchmarks Are and Why They Matter
Steam Machine benchmarks are early performance tests uploaded to databases like Geekbench that measure how Valve’s upcoming mini PC handles CPU-heavy tasks and indicate how close the hardware is to launch. The latest entries, labeled under Valve’s internal “Fremont” codename and tagged as SteamOS systems, show the Steam Machine in an active testing phase rather than in a lab-only prototype stage. These benchmarks focus on single-core and multi-core workloads, so they do not measure full gaming performance, but they reveal how well the CPU will cope with game logic, background tasks, and general desktop use. Their arrival also lines up with rumors that review units have gone out, since this is the first time SteamOS-based results have appeared, following an earlier Windows-only run in August. Together, they signal a maturing platform edging closer to release.
Inside the Hardware: Zen 4 CPU and RDNA 3 GPU in a Cube
The Steam Machine benchmarks list an “AMD Custom CPU 1772” with 6 cores and 12 threads, paired with 16GB of RAM and clock speeds reaching 4.8GHz. This aligns with Valve’s description of a semi-custom Zen 4 processor and a dedicated RDNA 3 GPU inside the compact, cubed mini PC form factor. Unlike the Steam Deck’s system-on-chip, which combines Zen 2 CPU and RDNA 2 graphics into one package to fit a handheld shell, the Steam Machine has more room to separate CPU and GPU, improving thermal headroom and sustained performance. The move to Zen 4 alone implies higher per-core efficiency and better modern instruction support. For gaming PC performance, this design suggests the Steam Machine is built to sit under a TV or monitor and run more demanding titles at higher settings than the handheld, while still remaining SteamOS-driven.
How Steam Machine Benchmarks Compare to Steam Deck Scores
The new Geekbench results show a clear CPU advantage for the Steam Machine over the Steam Deck, even if they are not final. In two back-to-back tests on Geekbench 6.7.1 for Linux x86, the Steam Machine scores 2,334 and 2,282 in single-core and 7,316 and 7,392 in multi-core. By comparison, database entries for the Steam Deck on Geekbench 6.2.2 report around 1,353 single-core and 4,573 multi-core. According to PC Guide, “the mini PC offers a considerable uplift over the Steam Deck,” with Valve marketing the Steam Machine as up to six times more powerful overall. Part of this uplift comes from going from a 4-core, 8-thread, up-to-2.8GHz Zen 2 CPU to a 6-core, 12-thread Zen 4 chip at 4.8GHz. For players, this should translate into faster load times, better frame pacing, and more headroom for multitasking alongside games.
What the Benchmarks Reveal About Launch Readiness and Thermal Efficiency
Beyond raw numbers, the context of these Geekbench entries hints at how close the Steam Machine is to launch. Steam Deck HQ notes these are the first SteamOS-based tests to appear in the browser, replacing earlier Windows-only results from last August and pointing to tests on near-final software. Their timing follows rumors that review units have gone out and fits Valve’s own confirmation that the device is planned for a summer release. While Geekbench is not a thermal test, consistent scores across two back-to-back runs suggest the CPU maintains clock speeds without heavy throttling, a positive sign for thermal efficiency in the small chassis. For now, Valve and reviewers both stress that these are pre-release figures. Still, the combination of Zen 4 efficiency, dedicated RDNA 3 graphics, and stable benchmark behavior indicates a platform that looks close to being launch-ready.
