Thief

The AMD Ryzen 7 5800XT paired with the NVIDIA GeForce RTX 4070 delivers a robust performance profile in Thief, with the data showing a system that scales predictably across resolutions and settings. The measured frames per second (FPS) reveal a configuration where the GPU becomes the primary bottleneck only at higher resolutions and quality presets, while the CPU provides ample headroom at lower loads. This analysis breaks down the measured FPS rows to interpret the limiting components and provide actionable settings guidance.

Resolution Scaling

The measured FPS data shows a clear and expected degradation as resolution increases from 1920x1080 to 3840x2160. At Low settings, the system delivers 175.3 FPS at 1080p, which drops to 152.0 FPS at 1440p and further to 105.3 FPS at 4K. This represents a substantial 40% reduction in average FPS from 1080p to 4K at Low settings, indicating that even at the lowest graphical load, the higher pixel count places a significant burden on the rendering pipeline.

Under High settings, the scaling is more pronounced. The average FPS falls from 142.0 at 1080p to 100.0 at 1440p, and finally to 60.3 at 4K. The drop from 1440p to 4K is particularly steep, representing a 40% performance loss, which strongly suggests that the NVIDIA GeForce RTX 4070’s memory bandwidth and fill rate are being saturated at the higher resolution. The Ultra preset shows a similar pattern, with 139.9 FPS at 1080p, 94.5 FPS at 1440p, and 55.1 FPS at 4K.

The gap between 1080p and 1440p is smaller than the gap between 1440p and 4K across all presets. For instance, at Medium settings, the FPS goes from 155.6 at 1080p to 129.5 at 1440p (a 17% drop), then to 76.1 at 4K (a 41% drop). This non-linear scaling indicates that the system is not purely CPU-limited at 1080p; otherwise, the FPS would remain flat. Instead, the data suggests that while the CPU is capable of high frame rates, the GPU’s architecture begins to struggle as the pixel count approaches 4K, making it the definitive limiting component at that resolution.

At 4K, even the Low preset cannot maintain a frame rate above 105.3 FPS, while the Ultra preset dips below 60 FPS. This shows that 4K gaming on this combination is viable but requires careful settings management to maintain smooth gameplay.

GPU Role

The NVIDIA GeForce RTX 4070 is the central component in determining the frame rate at higher resolutions. Its 12 GB of GDDR6X memory and 192-bit bus width provide a memory bandwidth of 504.2 GB/s, which is a critical resource for rendering Thief’s detailed environments at high pixel counts. The data shows a clear correlation between the GPU’s workload and the FPS drop at 4K, confirming that the graphics card is the bottleneck in this scenario.

The GPU’s clock speeds, with a base of 1920 MHz and a boost of 2475 MHz, are responsible for its compute throughput. The benchmark scores further illustrate its capabilities: the Passmark G3D score of 26927 and the 3DMark Steel Nomad DX12 score of 3854 place it in the 81st percentile among all GPUs. Its nearest rivals, such as the AMD Radeon RX Vega 56 with a deltaPct of -0.6, show that the RTX 4070 performs within a narrow band of its direct competitors, but the data indicates it is not a top-tier part for extreme resolutions.

The GPU’s 5888 shading units and 184 texture mapping units (TMUs) contribute to its texture fill rate of 455.4 GTexel/s. This high texturing capability is why the FPS at 1080p and 1440p remains high, as the GPU can process the geometry and textures without becoming the limiting factor. However, the pixel rate of 158.4 GPixel/s and 64 ROPs become strained at 4K, which is why the FPS drops so sharply between 1440p and 4K. The data suggests that the RTX 4070 is over-provisioned for 1080p gaming but adequately matched for 1440p, while 4K pushes its limits.

CPU Role

The AMD Ryzen 7 5800XT plays a supporting role in this configuration, proving sufficient to keep the GPU fed at lower resolutions. With 8 cores and 16 threads, this Zen 3 processor has a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its Cinebench R23 multi-core score of 23794 and single-core score of 3359 demonstrate strong raw compute power, placing it in the 86th percentile of all CPUs.

At 1080p, the FPS differences between presets are relatively small, ranging from 139.9 at Ultra to 175.3 at Low. This narrow margin indicates that the CPU is not the primary constraint at this resolution; the GPU’s performance is the differentiator. However, the CPU’s 32 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth ensure that game logic and asset streaming do not cause stutters, allowing the FPS to remain high.

The CPU’s benchmark scores, such as the 3DMark 16-thread score of 7683 and the Passmark multi-thread score of 27988, show it is a capable multi-tasking part. Its nearest rivals, including the AMD Ryzen 7 PRO 5755GE with a deltaPct of 0.1, are all within a 0.3% performance delta, indicating that the 5800XT is a well-balanced processor. The data reveals that even in the most CPU-intensive scenarios at 1080p, the processor does not cause a bottleneck, as the FPS does not plateau regardless of the settings.

The CPU’s role becomes more pronounced when comparing the 1080p and 1440p results. The average FPS drop from 1080p to 1440p is consistent across presets, which suggests the CPU is still capable of maintaining high frame rates, and the GPU is taking on the extra load. Only at 4K does the CPU’s influence wane, as the GPU’s limits are reached first.

Settings Recommendations

Based on the measured FPS rows, the optimal balance between visual quality and performance for this system is the High preset at 2560x1440. This configuration achieves 100.0 FPS, which is well above the 60 FPS threshold for smooth gameplay, while still offering a significant visual upgrade over Medium settings. The data shows that High at 1440p provides a 6% performance increase over Ultra at the same resolution, while the visual difference is typically minimal in Thief.

For users with a 1920x1080 monitor, the Ultra preset is the best choice, as it delivers 139.9 FPS, which is only slightly below the High preset’s 142.0 FPS. This indicates that the system has ample headroom at 1080p to run the highest settings without a meaningful performance penalty. The Medium preset at 1080p offers 155.6 FPS, but the incremental gain over Ultra does not justify the loss in visual fidelity.

At 3840x2160, the High preset is the recommended choice, providing 60.3 FPS. This is just above the 60 FPS target for most displays, making it the best balance of quality and performance. The Ultra preset at 4K, with 55.1 FPS, drops below the 60 FPS threshold and may result in noticeable stutter, while the Medium preset’s 76.1 FPS offers a smoother experience but with reduced detail. For the best experience at 4K, the data suggests sticking with High settings to avoid the performance cliff seen in Ultra.

The Low preset is not recommended for any resolution, as the FPS gains are not proportional to the loss in visual quality. The system is capable of running the game at High or Ultra on 1080p and 1440p displays, and the data indicates that users should prioritize these settings over lower presets.
