quickutilities – Valve’s July 2025 Steam Hardware and Software Survey reveals a major milestone for AMD processors. For the first time, AMD CPUs power over 40 percent of all participating PCs on the platform. Meanwhile, Intel’s share has dropped below 60 percent, marking a significant decline from the roughly 77 percent it held five years ago. This shift highlights changing preferences among gamers and PC enthusiasts.
AMD’s rise on Steam is largely due to the popularity of its 3D V-Cache chips, including the Ryzen 7 9800X3D. These processors combine strong gaming performance with competitive pricing, making them highly appealing to Steam users. This trend continues to chip away at Intel’s market share, reflecting AMD’s growing competitiveness in gaming-focused CPUs.
The survey also tracks operating system usage. Windows 11 (64-bit) now runs on 59.9 percent of Steam PCs, slightly increasing by 0.06 percent from the previous month. Windows 10’s share has fallen to 35.19 percent as its October 2025 support deadline approaches. Notably, Linux use has reached 2.89 percent, the highest consistent level seen in recent years, suggesting a slow but steady rise among certain user segments.
Memory configurations on Steam PCs are also evolving. While 16 GB of RAM remains the most common, installed in roughly 42 percent of machines, systems with 32 GB have grown to 35.15 percent, up 0.78 percent from last month. This growth reflects the increasing demands of modern games and multitasking needs. Overall, the July data shows that Steam users continue to upgrade to more powerful hardware and newer software. AMD’s CPU gains and Windows 11’s adoption point to a gradual but steady modernization of the gaming PC base.

The GPU landscape on Steam remains dominated by Nvidia, which accounts for 73.94 percent of all discrete graphics cards in the survey. Nvidia’s new mid-range Blackwell GPUs, particularly the RTX 5070, are gaining traction quickly. The RTX 5070 now holds a 1.32 percent share, increasing by 0.33 percentage points in July alone. The RTX 5060 also shows progress, securing 0.60 percent of the market.
In contrast, AMD’s latest Radeon 9000 series, based on the RDNA 4 architecture, remains absent from Steam’s report. No RX 9070 or RX 9060 models have reached the survey’s reporting threshold. This likely reflects either supply constraints or slower initial adoption among gamers.

VRAM trends show that 8 GB remains the most common graphics memory size, present in 33.66 percent of GPUs. However, 12 GB cards are growing rapidly and now constitute 19.22 percent of the market, marking the fastest increase last month. This shift highlights gamers’ rising demand for GPUs with more memory to handle increasingly complex and detailed games.
Taken together, Valve’s July 2025 survey reflects a gaming PC user base steadily moving toward more capable hardware. The combination of AMD’s growing CPU presence and Nvidia’s expanding GPU lineup points to a hardware ecosystem in transition. As AMD continues to strengthen its CPU market share and Nvidia solidifies its GPU dominance, the coming months should reveal whether AMD’s latest graphics cards can close the gap and challenge Nvidia’s lead.
