Thief

Launched in 2014, Thief remains a demanding title for modern hardware, particularly at higher resolutions. This analysis examines the measured performance of the AMD Ryzen 5 3600 paired with the NVIDIA GeForce RTX 5070 across 1080p, 1440p, and 4K resolutions with Low, Medium, High, and Ultra presets. The data reveals a system that scales predictably with resolution, with the RTX 5070 providing substantial headroom at 1080p and the Ryzen 5 3600 becoming a more significant factor as frame rates climb.

Resolution Scaling

The measured FPS data shows a clear and consistent scaling pattern as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 103 FPS at 1080p to 91 FPS at 1440p, a reduction of approximately 11.7%. Moving from 1440p to 4K at High settings yields a further drop from 91 FPS to 63 FPS, a steeper 30.8% decline. This trend indicates that the RTX 5070 is the primary performance driver at 1440p and 4K, as the GPU's rendering workload scales directly with pixel count.

The scaling behavior becomes even more pronounced when examining the Low preset. At 1080p Low, the system achieves 126 FPS, which drops to 111 FPS at 1440p (an 11.9% reduction) and then to 93 FPS at 4K (a 16.2% reduction from 1440p). The fact that the Low preset at 4K still delivers 93 FPS suggests that the RTX 5070 has ample compute headroom, and the performance delta between 1440p and 4K is relatively modest compared to the High preset. This points to a scenario where, at lower graphical loads, the CPU begins to play a more substantial role in limiting the maximum achievable frame rate.

Analyzing the Ultra preset provides the clearest evidence of the GPU's influence. At 1080p Ultra, the system averages 101 FPS, nearly identical to the 103 FPS seen at High. At 1440p Ultra, the average is 89 FPS, and at 4K Ultra, it falls to 60 FPS. The relatively small gap between High and Ultra at 1080p (103 vs. 101 FPS) suggests that Ultra settings introduce additional GPU load that the RTX 5070 can still handle comfortably, but the 4K Ultra result of 60 FPS indicates a hard limit where the GPU is fully saturated.

The Medium preset offers the only complete data set with min and max FPS values. At 1080p Medium, the average is 114 FPS with a minimum of 97 FPS and a maximum of 131 FPS. At 1440p Medium, the average drops to 100 FPS (min 85, max 115), and at 4K Medium, the average is 83 FPS (min 71, max 96). The frame time variance, as shown by the spread between min and max, increases slightly at higher resolutions, but the overall consistency remains good. This data supports the interpretation that the RTX 5070 is the limiting component at 4K Medium, where the average FPS of 83 is still well above the 60 FPS threshold but shows a clear downward trend.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. Its benchmark scores position it as a solid mid-range performer, with a Cinebench R23 multi-core score of 15045 and a single-core score of 2124. In the context of Thief, a stealth game that relies heavily on CPU-bound game logic and AI pathfinding, the Ryzen 5 3600's capabilities are directly reflected in the measured frame rates.

The data shows that the CPU is not the primary bottleneck at 4K resolutions. At 4K Ultra, the system averages 60 FPS, and at 4K High, it averages 63 FPS. These frame rates are likely limited by the RTX 5070's rendering throughput. However, at lower resolutions where the GPU has more headroom, the CPU's influence becomes apparent. At 1080p Low, the system hits 126 FPS, but at 1080p Ultra, it only reaches 101 FPS. This 25 FPS difference at the same resolution is primarily due to the increased graphical workload, but the fact that the 1080p Low result does not exceed 126 FPS suggests a CPU-imposed ceiling.

The Ryzen 5 3600's 12 threads are leveraged effectively in Thief, which is known to utilize multiple cores. The processor's 3DMark 8-thread score of 3844 and max-thread score of 4603 indicate that it can sustain high multi-threaded workloads. The data suggests that while the CPU can push frame rates past 100 FPS at 1080p, it cannot reach the 144+ FPS territory that higher-clocked or newer processors might achieve. The performance spread between 1080p and 1440p at the High preset (103 vs. 91 FPS) shows that the CPU is still capable of driving the GPU effectively at 1440p, but the gap narrows as resolution increases, confirming that the RTX 5070 becomes the limiting factor.

Measured FPS Breakdown

At 1920x1080, the performance envelope is broad. The Low preset delivers an average of 126 FPS, which is the highest result in the entire data set. The Medium preset averages 114 FPS, with a minimum of 97 and a maximum of 131 FPS. The High preset averages 103 FPS, while the Ultra preset averages 101 FPS. The delta between High and Ultra at 1080p is minimal, suggesting that the Ultra preset's additional effects are not heavily taxing the RTX 5070 at this resolution.

Moving to 2560x1440, the frame rates remain high but show a clear step down. The Low preset averages 111 FPS, the Medium preset averages 100 FPS (min 85, max 115), the High preset averages 91 FPS, and the Ultra preset averages 89 FPS. The spread between Low and Ultra at 1440p is 22 FPS, which is slightly larger than the 25 FPS spread at 1080p, indicating that the GPU is starting to feel the load of higher pixel counts.

At 3840x2160, the scaling becomes more pronounced. The Low preset averages 93 FPS, the Medium preset averages 83 FPS (min 71, max 96), the High preset averages 63 FPS, and the Ultra preset averages 60 FPS. The most significant drop occurs between Medium and High, where the average falls by 20 FPS from 83 to 63. This suggests that the High preset enables graphical features that are particularly demanding at 4K, such as higher-resolution textures or more complex shading. The 60 FPS average at Ultra is exactly at the threshold for smooth gameplay, and the lack of reported min FPS values for this setting implies that frame pacing may be less consistent.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture and features 12 GB of GDDR7 memory on a 192-bit bus, providing a memory bandwidth of 672.0 GB/s. Its boost clock is 2512 MHz, and it has 6144 shading units. In synthetic benchmarks, the RTX 5070 achieves a Passmark G3D score of 29137 and a 3DMark Steel Nomad DX12 score of 5077. These figures place it at the 82nd percentile of all GPUs, with an average benchmark score of 40377.

The measured FPS data directly reflects the RTX 5070's capabilities in Thief. At 4K Ultra, the GPU is clearly the limiting component, as the average frame rate of 60 FPS aligns with the GPU's rendering ceiling. The fact that the 4K Low preset achieves 93 FPS, while the 4K High preset only reaches 63 FPS, highlights how sensitive the game's visual settings are to GPU load. The RTX 5070's 12 GB of VRAM is sufficient for Thief at all tested settings, as the game's 2014-era textures do not exceed this capacity even at 4K Ultra.

The GPU's performance relative to its nearest rivals is notable. Its average benchmark score of 40377 is 0.2% higher than the AMD Radeon Pro 580 and 0.8% higher than the AMD Radeon Pro WX 7100. However, it trails the AMD Radeon Pro 5300 by 1.2%. This positioning in synthetic tests does not perfectly translate to gaming performance, but it indicates that the RTX 5070 is a strong performer in its class. The GPU's 672.0 GB/s of memory bandwidth is a key asset for 4K gaming, as high-resolution textures require substantial data throughput.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the best balance of visual quality and performance across all three resolutions. At 1080p Medium, the system averages 114 FPS with a minimum of 97 FPS, ensuring smooth gameplay with no noticeable stutter. At 1440p Medium, the average of 100 FPS (min 85) remains well above the 60 FPS threshold, providing an excellent experience for high-refresh-rate monitors. Even at 4K Medium, the average of 83 FPS (min 71) is comfortable for most displays.

The High preset is a viable alternative for users with 1080p or 1440p displays who prioritize visual fidelity. At 1080p High, the average of 103 FPS is still highly playable, and at 1440p High, the 91 FPS average is also strong. However, at 4K High, the average drops to 63 FPS, which is close to the 60 FPS minimum for smooth gameplay. The Ultra preset is only recommended for 1080p or 1440p use, where it achieves 101 FPS and 89 FPS respectively. At 4K Ultra, the 60 FPS average leaves no headroom for demanding scenes, making it a risky choice for consistent performance.

For users targeting 4K, the Low preset provides the highest frame rates, averaging 93 FPS, but the visual compromise may be significant. The Medium preset at 4K strikes the best compromise, delivering 83 FPS with a minimum of 71 FPS, ensuring that the game remains fluid even during intense stealth sequences. The data shows that the RTX 5070 is capable of handling Thief at 4K Medium with ease, and the Ryzen 5 3600 provides sufficient CPU support to avoid becoming a bottleneck at this resolution.
