Valve's October 2026 Steam Hardware & Software Survey shows 16GB of system memory back as the most common configuration among Steam users, with the GeForce RTX 3060 once again the most-used graphics card. Both results reverse September's data, and the way they changed says as much about who answered the survey as it does about what gamers are buying.
What the October numbers show
According to Valve's published results, systems with 16GB of RAM rose 3.60 percentage points to 41.42%, while 32GB systems fell 5.16 points to 37.06%. Reports on the September survey had 32GB briefly overtaking 16GB for the first time, so October largely restores the earlier order.
On graphics cards, the RTX 3060 sits at 3.62% of surveyed systems, up 0.08 points. The RTX 5070, which led September's chart, fell 2.30 points to 3.56%, leaving the two cards almost level. Other recent GeForce cards also slid: the RTX 5060 dropped 1.23 points to 2.97%, and the RTX 5060 Ti fell 1.32 points to 2.55%.
Among CPUs, four-core systems gained 1.57 points to 12.36%. Eight-core systems are still the most common but fell 1.38 points to 28.68%, while six-core systems barely moved at 27.29%.
Why caution is warranted
The survey is voluntary and anonymous, and Valve's own tables show the respondent mix changed sharply in October. Simplified Chinese-language systems fell 9.41 points to 21.98%, while English rose 4.84 points to 39.04%. Wccftech's coverage points to this change in survey composition as a likely contributor to the month's swings.
Other tables moved in ways that have little to do with hardware budgets. The share of 1440p primary displays dropped 5.22 points to 21.82%, while 1080p rose 2.32 points to 50.23%. RAM figures were not uniformly downward either: 64GB systems edged up 0.23 points, even as 8GB systems grew 1.05 points to 7.52%.
Where AI-driven memory prices fit
Memory has become more expensive this year, and the cause is well documented. In July, TrendForce said AI server demand continues to support memory prices and that capacity moving toward server applications is shrinking the supply available for PC memory. It forecast conventional DRAM contract prices to rise another 13–18% in the third quarter, a slower pace than before because consumer demand was weakening and prices were already at record highs.
That backdrop makes it plausible that some buyers are choosing 16GB over 32GB or holding on to older graphics cards. Survey data alone cannot show why individual users configured their machines as they did, and the October figures do not isolate AI-driven pricing as the cause.
What remains unclear
Valve does not publish response counts or explain month-to-month changes in who takes part. One month of results that undo September's jumps does not establish a trend, and November's survey will show whether the October pattern holds.
