V has released its Steam Hardware Survey data for December 2025, revealing a notable shift in the processor market. AMD's processor share on the Steam platform has surged to 47.27%, marking a 4.66% increase within just a month and a cumulative growth of around 7% over the past four months. In contrast, Intel's processor share stands at 55.47%, with the gap between the two narrowing significantly.

Despite the scarcity of DDR5 memory and rising prices that are expected to reach new heights in 2025, AM5 platforms have completely phased out support for DDR4, leaving the Ryzen 7000 and 9000 series compatible only with DDR5. Theoretically, this limitation should benefit Intel platforms, which continue to support DDR4. Additionally, Raptor Lake Refresh still surpasses the newer Arrow Lake in gaming performance, offering both DDR4 and DDR5 dual-channel options for greater cost flexibility.

However, the Steam data tells a different story. A significant number of gamers have opted for AMD's older platforms instead. Throughout the holiday season, the Ryzen 7 5800X and 5800XT were among the best-selling models on e-commerce sites. The discontinued 5800X3D remained active in the secondary market, commanding prices higher than the brand-new 9800X3D in certain regions. This reflects gamers' balancing act between limited budgets and desired platform stability and gaming performance.

The X3D models are pivotal in this trend. The substantial 3D V-Cache has consistently demonstrated its advantages in enhancing game load speeds, especially in high-frame-rate, low-latency environments, independent of the latest architecture. On the other hand, some gamers remain cautious about Intel processors due to the stability issues that arose in 2024, a historical factor contributing to the erosion of Intel's once near 80% market dominance on the Steam platform.

Changes in memory configurations are also noteworthy. Although prices remain high, there is an overall increase in memory capacity among Steam players. According to the latest survey, the share of systems with 32GB and above rose to 39.07%, a 2.11% monthly increase, equaling the number of users with 16GB. This trend is tied to consumer-grade memory supply being squeezed by increased AI and enterprise demand. As manufacturers redirected production capacity to HBM and data center markets, fluctuations in consumer prices accelerated some gamers' upgrade decisions to circumvent future cost hikes.

The GPU market has seen relatively modest changes, with NVIDIA maintaining a dominant 73.28% share. The RTX 3060 remains the most popular individual model on Steam, holding a 6.53% share. The Blackwell architecture RTX 50 series collectively accounts for 12.72%, with the RTX 5070 being the most frequently used Blackwell GPU at 3.05%. For AMD, the RDNA 4-based Radeon RX 9070 made its first appearance in the statistics in December, capturing a 0.22% share, while many AMD models continue to be grouped under the "unspecified" category.

In terms of overall resolution distribution, 1080p remains the most common choice, representing 53.68% of users, while 1440p continues to grow, reaching 21.77%, and 4K accounts for 5.47%. Faced with constraints from both graphics card prices and memory specifications, players are leaning towards higher refresh rates at 1080p or 1440p, rather than increasing resolution. This display trend emphasizes the importance of CPU gaming performance and cache efficiency.

Overall, the data indicates that changes on the Steam platform are not about a complete generational upgrade but rather a strategic rebalancing around cost, stability, and actual gaming outcomes. AMD's growing market share isn't solely reliant on its latest platforms. Instead, it continues to attract users from existing stock through its X3D models and mature architectures, exerting more direct pressure on Intel during this period.
