Thief

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor built on the Zen 3 architecture with a 7 nm process. It runs at a base clock of 3.50 GHz and boosts to 4.40 GHz, with 32 MB of shared L3 cache and 512 KB of L2 cache per core. The CPU supports DDR4 memory via a dual-channel bus, delivering 51.2 GB/s of memory bandwidth. Its 65 W TDP places it firmly in the mainstream desktop segment, and it uses the AMD Socket AM4 platform. The processor’s 3DMark single-thread score of 882 and PassMark single-thread score of 3256 indicate solid per-core performance for a 2022 release.

In Thief, a 2014 stealth title, the CPU’s role is less about raw thread count and more about consistent frame pacing and draw-call handling. The Ryzen 5 5600’s 12 threads are more than sufficient for a game of this era, which was designed around quad-core CPUs. The processor’s Cinebench R23 multi-core score of 18309 and single-core score of 2584 show that it can handle both lightly threaded game logic and background tasks without becoming a bottleneck. The PassMark multithread score of 21541 further confirms this, placing the CPU in the 79th percentile among all tested processors.

Benchmark results indicate that at 1080p, where CPU overhead is most pronounced, the combination still achieves 129.1 FPS on High settings. This suggests the 5600 is not limiting the experience at lower resolutions. The CPU’s nearest rivals in average benchmark score include the Intel Xeon D-1746TER (0.6% higher), AMD EPYC 9554P (0.6% lower), and AMD EPYC 9534 (0.6% lower), while the Intel Core i7-11700F trails by 0.9%. These are all server or workstation parts, which underscores that the 5600’s desktop-oriented design is well matched to gaming workloads like Thief. The game’s stealth mechanics rely on AI pathfinding and reactive environments, both of which benefit from the 5600’s strong single-thread performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 9070 XT is built on the RDNA 4.0 architecture with a 4 nm process, featuring 4096 shading units, 256 texture mapping units, and 128 ROPs. It carries 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The GPU’s base clock is 1660 MHz, with a boost clock of 2970 MHz and a game clock of 2400 MHz. Memory runs at 2518 MHz (20.1 Gbps effective). The card draws up to 304 W and requires a 700 W power supply. Its PassMark G3D score of 26795 places it in the 82nd percentile among all GPUs.

For a 2014 game like Thief, the RX 9070 XT is massively overprovisioned in terms of raw compute. The GPU’s FP32 performance of 48.66 TFLOPS and pixel rate of 380.2 GPixel/s are far beyond what this title’s rendering pipeline can utilize. However, the 16 GB VRAM becomes relevant because Thief’s Ultra preset at 4K can consume significant memory for textures and shadow maps. Benchmark data shows the GPU maintains 56.6 FPS at 4K Ultra, which is playable but not smooth, indicating that even a modern high-end GPU struggles with this game’s older engine at maximum settings.

The GPU’s nearest rivals in average benchmark score include the AMD Radeon Pro 575 (0.1% higher), NVIDIA RTX A500 Mobile (0.2% lower), and AMD Radeon Pro 575X (0.5% higher). The RX 9070 XT outperforms the Radeon RX Vega 64 by 0.6%. These deltas are small, suggesting that the GPU’s performance class is well established. In Thief specifically, the GPU’s DirectX 11 PassMark score of 292 indicates strong compatibility with the game’s API, which is reflected in the measured frame rates across resolutions.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern. At 1080p High, the combo delivers 129.1 FPS; at 1440p High, it drops to 101.9 FPS; and at 4K High, it falls to 58.8 FPS. This represents a 54.4% drop from 1080p to 4K. The Low preset shows a smaller relative decline: 160.1 FPS at 1080p, 140.1 FPS at 1440p, and 102.5 FPS at 4K, a 36.0% reduction. Medium settings follow a similar pattern: 147.6 FPS at 1080p, 127.5 FPS at 1440p, and 77.2 FPS at 4K, a 47.7% drop. Ultra settings show the steepest decline: 129.7 FPS at 1080p, 96.4 FPS at 1440p, and 56.6 FPS at 4K, a 56.4% reduction.

These scaling curves indicate that the GPU becomes the primary limiting component as resolution increases. At 1080p, the frame rates across presets are tightly clustered (ranging from 129.1 to 160.1 FPS), which suggests the CPU is keeping pace and the GPU has headroom. At 4K, the spread widens significantly (from 56.6 to 102.5 FPS), showing that the GPU’s fill rate and memory bandwidth are being taxed. The fact that Low at 4K (102.5 FPS) is nearly double Ultra at 4K (56.6 FPS) points to the game’s shader complexity and texture filtering being the main cost drivers.

The 1080p to 1440p transition is gentler, with average drops of 20-25 FPS across presets. This suggests that at 1440p, the system is still balanced, but the GPU is beginning to feel the load. The 1440p to 4K jump is the most punishing, with losses of 43-45 FPS on High and Ultra. For a 2014 game running on modern hardware, this pattern is typical: older engines often have inefficient draw calls and memory management that disproportionately hurt at higher resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 5 5600 and AMD Radeon RX 9070 XT ranks 505th out of 1642 tested combos in Thief. This places it in the 69th percentile of all configurations, meaning roughly 31% of tested combos perform better in this game. Given that the GPU is a high-end 2025 release and the CPU is a mid-range 2022 part, this ranking reflects a slight mismatch: the GPU is capable of much higher frame rates, but the CPU’s single-thread performance, while solid, is not exceptional by modern standards.

The rank is more impressive when considering the game’s age. Thief was released in 2014, and its engine was designed for hardware of that era. The fact that this combo still ranks in the top 31% of all tested configurations suggests that both components are handling the game’s legacy code well. The CPU’s 79th percentile ranking among all CPUs and the GPU’s 82nd percentile among all GPUs are both strong, but the combo’s 69th percentile in this specific game indicates that the pairing is slightly less effective than the individual parts’ standings would suggest.

Comparatively, if the CPU were upgraded to a newer, faster part, the GPU could likely push higher frame rates at 1080p, where the CPU bottleneck is more evident. At 4K, however, the ranking would likely improve because the GPU becomes the dominant factor. The data shows that at 4K High, the combo achieves 58.8 FPS, which is just shy of the 60 FPS target that many users consider the threshold for smooth gameplay. At 1440p High, the 101.9 FPS result is well above that threshold, making this combo a strong candidate for high-refresh-rate 1440p gaming in Thief.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS rows provide a clear picture of the trade-offs between visual quality and performance. At 1080p, every preset exceeds 129 FPS, with Low reaching 160.1 FPS and Medium at 147.6 FPS. The Ultra preset at 1080p delivers 129.7 FPS, which is only 0.6 FPS higher than High’s 129.1 FPS. This near-identical performance suggests that Ultra and High at 1080p are effectively equivalent in frame rate, so the choice comes down to visual quality. Given that a 2014 game’s Ultra settings typically include enhanced shadows and ambient occlusion, and the frame rate cost is negligible, Ultra is the recommended preset at 1080p.

At 1440p, the situation changes. High delivers 101.9 FPS, Medium hits 127.5 FPS, and Low reaches 140.1 FPS. Ultra drops to 96.4 FPS. The gap between High and Ultra is 5.5 FPS, which is noticeable but not dramatic. For users with 1440p displays running at 60 Hz or 75 Hz, Ultra is still viable. However, for 1440p 144 Hz monitors, Medium or High would be a better choice to maintain higher frame rates. The data suggests that High at 1440p provides a balanced experience: it delivers 101.9 FPS, which is well above the 60 FPS threshold, while retaining most of the visual improvements over Medium.

At 4K, the choices become more constrained. Ultra drops to 56.6 FPS, which is below the 60 FPS target. High achieves 58.8 FPS, barely above 60 FPS but still close. Medium reaches 77.2 FPS, providing a comfortable margin above 60 FPS. Low hits 102.5 FPS, which is excellent for 4K but sacrifices the visual fidelity that makes Thief’s atmospherically lit environments shine. For 4K users, Medium is the recommended preset: it delivers 77.2 FPS, which is smooth, while retaining enough texture detail and shadow quality to preserve the game’s stealth-heavy mood. The 4K Ultra and High presets are not recommended because their sub-60 FPS results can cause stutter in a game where precise timing matters for stealth mechanics.

Overall, the best experience per the measured rows is 1080p Ultra for maximum visual quality, 1440p High for a balance of quality and speed, and 4K Medium for users who prioritize smooth gameplay over maximum detail. The combo’s 16 GB VRAM ensures that memory capacity is never a concern, even at 4K Ultra, so the frame rate drops are purely a function of GPU compute and the game’s engine limitations.
