What the New Steam Machine Benchmarks Tell Us
The Steam Machine is Valve’s upcoming cube-shaped mini PC built around SteamOS, using a custom AMD Zen 4 CPU and RDNA 3 GPU to deliver console-like gaming performance in a compact, standardized box aimed at sitting between a handheld and a full desktop rig. Recent Steam Machine benchmarks labeled under the “Fremont” codename have appeared in the Geekbench 6.7.1 database, giving the first clear look at CPU performance. Running an “AMD Custom CPU 1772” with 6 cores, 12 threads, boost clocks close to 4.8 GHz and 16 GB of RAM, the system posts single-core scores around 2,300 and multi-core results near 7,400. Against older Steam Deck results from Geekbench 6.2.2, that translates into nearly double the CPU performance, matching Valve’s positioning of the Steam Machine as a much more capable home system than its handheld console.
Steam Deck vs Steam Machine: Nearly Double the CPU Power
Comparing Steam Deck vs Steam Machine on Geekbench performance scores highlights how substantial the uplift is. The Steam Deck’s APU typically scores about 1,353 in single-core and 4,573 in multi-core tests, while the Steam Machine’s pre-release runs reach 2,282–2,334 single-core and 7,316–7,392 multi-core. In practice, that means faster game loading, smoother background downloads during play and better performance in CPU-heavy titles or simulations. According to PC Guide, “you can expect almost a doubling of the performance in the CPU department alone” when moving from a Steam Deck to a Steam Machine. Since both devices target SteamOS and the same game library, this makes a strong case for the Steam Machine as a living-room or desktop partner to the handheld, rather than a direct replacement, especially for players chasing higher frame rates and more demanding settings.
How the Custom AMD Chip Compares to Ryzen and PS5
Under the hood, the Steam Machine uses a semi-custom AMD Zen 4 CPU paired with a discrete RDNA 3 GPU featuring 28 compute units and its own 8 GB of GDDR6. Running at a 30W power envelope, the chip’s single-core score around 2,300 and multi-core score near 7,400 place it close to a 6-core Ryzen 5 5600X from 2020, even though that desktop part typically runs at more than double the power. WCCFtech notes that the newer Ryzen 5 7600X still sits ahead, which is expected given its higher TDP and desktop focus. The same analysis points out that the Steam Machine’s single-core results are nearly double those of the PlayStation 5, underscoring how far low-power Zen 4 designs have come. For a compact SteamOS box at 30W, this AMD custom chip performance suggests desktop-like responsiveness for everyday gaming and multitasking.
Single-Channel DDR5: A Compromise with an Upgrade Path
One controversial part of the spec sheet is memory: the Steam Machine ships with a single 16 GB DDR5 SODIMM, which means single-channel bandwidth instead of the usual dual-channel configuration. In theory, this can hurt performance in CPU-intensive games or cause stutters when the processor needs to stream a lot of data from RAM. Valve engineer Yazan Aldehayyat explained to Digital Foundry that sourcing 8 GB DDR5 SODIMMs was “literally impossible,” forcing Valve to ship one 16 GB stick rather than two 8 GB modules. The upside is that the system has two SODIMM slots, so owners can add a second 16 GB module later for 32 GB total and dual-channel performance. SteamDeckHQ notes that most games are unlikely to suffer major slowdowns, but players of heavy strategy, simulation, or modded titles may benefit from a memory upgrade.
What the Numbers Mean for 1440p Gaming and Launch Timing
With CPU scores nearing a Ryzen 5 5600X and a 28-CU RDNA 3 GPU on board, the Steam Machine benchmarks hint at a system that should be comfortable with 1080p at high settings and 1440p gaming at higher frame rates than the Steam Deck, especially in titles that lean heavily on CPU performance. The discrete GPU and higher power budget than the handheld give it more headroom for demanding modern games, while SteamOS and Valve’s “Verified” program help ensure compatibility; Valve has said that any Steam Deck Verified title should also be Steam Machine Verified. The close timing of back-to-back Geekbench uploads on June 15 suggests that review units are now in testers’ hands, lining up with Valve’s stated summer launch window. For players weighing a handheld console comparison or a compact living-room PC, these Steam Machine benchmarks point to a capable new mid-range option.
