Valve has confirmed that the first batch of Steam Machines will only come with a single stick of 16GB RAM, limiting the device to single-channel memory. The company confirmed this in a correction to Gamers Nexus (GN), after its engineers initially said that Steam Machines could either come with a single 16GB stick or two 8GB sticks. “We misspoke here,” Valve wrote in its email to the media channel. “All units will actually have one 16GB stick of RAM.”
Tests have shown that using single-channel memory can reduce performance by about 9% to 13% compared to dual-channel memory, meaning gamers will feel the difference, especially in 1% lows. This is especially hard on the Steam Machine, which uses already aging hardware — a semi-custom AMD Zen 4 CPU and RDNA3 graphics with only 8GB of GDDR6 VRAM. Note that AMD launched Zen 5 in 2024, while the RDNA4 GPUs dropped in early 2025. We also already have details for Zen 6 CPUs and have heard rumors that RDNA5 GPUs will arrive next year.
However, the company probably made this decision to keep the costs for the Steam Machine as low as possible. The device’s $1,049 base price is already steeper than what many are willing to pay for — an estimated $300+ price increase from the $700 to $750 target price that Valve presumably targeted. While its engineers did not confirm these numbers, they also said that the Steam Machine would have gotten a “probably similar” price hike to the one the Steam Deck experienced recently. Nevertheless, there is hope that later batches will have dual-channel memory, with Valve telling GN that there is a chance of this happening in the future.
This is another blow to the much-awaited living room PC console that is supposed to finally give PC gamers a chance to enjoy their Steam library with a console-like experience. Valve originally announced the Steam Machine and the Steam Controller in November last year, which was also around the same time that memory chips have started to be in short supply due to the massive demand from AI hyperscalers. The device was originally slated to launch in the first quarter of 2026, but the ongoing memory crisis forced Valve to hold off until it finally released the console this summer.
Although having only a single stick of RAM is a disadvantage to any system, more optimistic gamers can consider this a boon as they could easily upgrade the console to 32GB if they have an extra matching 16GB DDR5-5600 SODIMM stick lying around at home (or are willing to spend extra to buy one). Upgrading the console’s RAM is a rather involved affair, though, requiring you to remove a lot of components and sub-boards just to reach the RAM slots. But if you’re the adventurous kind and could score a good deal on laptop RAM, this might be a viable solution to getting more performance out of your Steam Machine.
