The video compares Valve’s Steam Machine performance against DIY PC builds using AMD GPUs, revealing that the Steam Machine generally performs between the RX 6600 and RX 7600, but is limited by its weaker CPU and single-channel memory configuration, resulting in less consistent frame times. Despite these limitations, the Steam Machine offers entry-level PC gaming comparable to current consoles, emphasizing the need for optimized settings and developer support to ensure smooth gameplay on Linux.
The video compares the performance of Valve’s Steam Machine against DIY PC builds using various AMD GPUs—specifically the RX 6600, RX 7600, and the higher-end RX 9060 XT—running games under Linux with optimized settings tailored for 8 GB GPUs. Testing includes demanding titles like Cyberpunk 2077: Phantom Liberty, Black Myth: Wukong, Resident Evil Requiem, Forza Horizon 6, Doom: The Dark Age, and Crimson Desert, all at native 1440p resolution or equivalent settings. The benchmarks are conducted with VSync disabled for maximum performance, although SteamOS defaults to VSync on, meaning the actual Steam Machine experience may appear slightly different.
In the tests, the Steam Machine generally performs between the RX 6600 and RX 7600 GPUs, often closer to the RX 6600 but sometimes edging nearer to the RX 7600. The RX 9060 XT, representing a more premium budget option with 16 GB VRAM, consistently outperforms the other GPUs by a significant margin, sometimes by over 70%. However, the video notes that the 9060 XT’s performance can be limited by CPU bottlenecks, leading to inconsistent frame times and less smooth gameplay, highlighting the importance of balancing CPU and GPU power in PC builds.
CPU performance is a critical factor in the Steam Machine’s overall gaming experience. The device uses a Hawk Point-based CPU paired with a single 16 GB SO-DIMM, resulting in single-channel memory bandwidth rather than the more optimal dual-channel configuration found in typical gaming PCs. This limitation leads to reduced CPU performance and spiky frame times in some games. Testing with Ryzen 5 CPUs shows that dual-channel memory significantly improves performance, and that Steam Machine’s CPU is notably weaker than mainstream desktop CPUs, underscoring a potential upgrade path for users.
Despite these limitations, the Steam Machine delivers what can be considered entry-level PC gaming performance, comparable to or slightly better than current-generation consoles in some scenarios. It handles older games well and can run modern titles with appropriate setting adjustments, much like consoles require. The video emphasizes the importance of optimized, lower-end presets for 8 GB GPUs to achieve a smooth and playable experience on the Steam Machine, suggesting that developers’ support through tailored settings and Valve’s APIs will be crucial for user satisfaction.
In conclusion, the Steam Machine offers a balanced, mainstream gaming experience that fits within a budget-conscious segment of the PC market, bridging the gap between consoles and DIY gaming PCs. While it doesn’t match the raw power of higher-end desktop GPUs and CPUs, it provides a viable platform for Linux gaming with some compromises. The video encourages viewers to consider the trade-offs in CPU and memory configuration, and to support further development and optimization efforts through Digital Foundry’s Patreon, which helps fund ongoing benchmarking and analysis work.
