Thief

The Intel Core i5-14600K paired with the AMD Radeon RX 580 produces a combination that is heavily constrained by its graphics component in Thief, a 2014 stealth title. The CPU, with its 14 cores and 20 threads running at a 3.50 GHz base and 5.30 GHz boost clock, provides substantial processing headroom. Its benchmark profile reinforces this, with a Cinebench R23 multi-core score of 32881 and a single-core score of 4642. However, the measured frame rates across all resolutions and settings suggest that this processing power is rarely the limiting factor. Instead, the data indicates a scenario where the GPU is consistently the bottleneck, as the CPU’s high single-thread performance is more than sufficient for the game's logic and physics.

The CPU’s architectural advantage is apparent in its percentile ranking, sitting at the 93rd percentile of all tested processors. Its average benchmark score of 49166 places it in close competition with the AMD Ryzen 9 5950X, which scores 49062, a mere 0.2% difference. It also edges out the Intel Core i5-14600KF by 0.4% (49367) and the AMD EPYC 4345P by 0.9% (49595). This level of performance means that the CPU can easily feed frames to the GPU. The fact that frame rates drop dramatically when moving from Low to Ultra settings, even at 1080p, points directly to the GPU as the component determining the experience. At 1080p Low, the combination achieves 85.7 FPS, which falls to 48.6 FPS at Ultra, a clear sign that the graphics card is being pushed to its limits while the CPU likely idles.

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

The Core i5-14600K is a modern desktop processor built on the Raptor Lake architecture, featuring a 10 nm process node. With 14 cores and 20 threads, it offers a robust foundation for multitasking and heavily threaded workloads. Its boost clock of 5.30 GHz is particularly relevant for gaming, as Thief's performance is often tied to single-threaded efficiency. The CPU's benchmark results show a strong balance: a Geekbench single-core score of 2803 and a multi-core score of 15846. This balance ensures that the processor does not introduce stutter or frame-pacing issues, even when the GPU is struggling to maintain high frame rates.

In the context of this specific game, the CPU's role is to handle the simulation and game logic. Given that the measured FPS drops from 85.7 at 1080p Low to 33.4 at 4K Low, the data suggests the CPU is never the primary constraint. If the CPU were the bottleneck, the frame rate would remain relatively flat across different resolutions, as the graphical load increases would not affect it. The observed decline indicates that the RX 580 is the limiting factor. The CPU’s performance relative to its nearest rivals, such as being 1% ahead of the Intel Xeon Gold 5318H, further confirms its capability. It is a high-end part that, in this pairing, is waiting on the GPU to deliver frames.

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

The AMD Radeon RX 580 is a much older graphics card, based on the GCN 4.0 architecture and utilizing a 14 nm process. It features 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. Its core clocks are 1257 MHz base and 1340 MHz boost, with a memory clock of 2000 MHz. These specifications, while respectable for its generation, are far below what is needed to drive modern titles at high settings. The GPU's benchmark percentile of 53rd place among all GPUs highlights its mid-range positioning. Its average benchmark score of 13559 is nearly identical to the NVIDIA GeForce GTX 570 (13564, 0% delta) and the NVIDIA GeForce GTX 950 (13549, 0.1% delta), showing that it is competitive with those older parts but not with the CPU it is paired with.

The measured FPS data shows the RX 580 struggling as resolution and settings increase. At 1080p Low, the card achieves 85.7 FPS, which is playable. However, at 1080p Ultra, the average drops to 48.6 FPS. This is a significant reduction, indicating that the GPU is running out of compute and memory bandwidth. The situation worsens at higher resolutions. At 1440p Ultra, the average is 30.2 FPS, and at 4K Ultra, it falls to a barely interactive 16.4 FPS. The 8 GB VRAM is not the issue at these settings for a 2014 game, but the raw shading power of 2304 shading units and 32 ROPs is insufficient. The data makes it clear that the GPU is the primary determinant of performance in this combination.

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

Based on the measured FPS, the optimal settings depend heavily on the target resolution and the user's tolerance for lower frame rates. At 1920x1080, the Low preset provides a very smooth experience at 85.7 FPS, which is ideal for fast-paced action. The Medium preset still offers a respectable 63.7 FPS, while High drops to 50.9 FPS. The Ultra preset, at 48.6 FPS, is borderline but may be acceptable for a stealth game where reaction time is less critical. For a smooth 60 FPS experience at 1080p, the Medium preset appears to be the best choice, as it offers a significant visual improvement over Low while maintaining a comfortable frame rate.

For users targeting 2560x1440, the options are more limited. The Low preset yields 59.8 FPS, which is the only setting that approaches a playable 60 FPS threshold. Medium drops to 44.8 FPS, and High to 32.9 FPS. At this resolution, the Low preset is the only viable option for a consistently smooth experience. At 3840x2160, all settings are below 34 FPS, with Low at 33.4 FPS. This resolution is not recommended for this combination, as even the lowest settings fail to provide a playable experience. Given the data, the best experience is at 1080p Medium, balancing visual fidelity and performance, or 1440p Low if higher resolution is preferred over visual details.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-14600K and AMD Radeon RX 580 ranks 1520 out of 1642 tested combinations in Thief. This places it in the bottom 7% of all tested pairings. This low ranking is a direct consequence of the massive performance gap between the CPU and GPU. The CPU is a top-tier processor, but the GPU is a mid-range part from an older generation. The pairing creates a significant bottleneck, where the GPU holds back the overall system performance. The data shows that this combo is not well-suited for this game, as most other combinations, likely with more balanced or newer GPUs, achieve higher frame rates.

This rank is particularly telling when considering the CPU's individual performance. The i5-14600K is in the 93rd percentile of all CPUs, but the combo's rank in the game is in the 7th percentile. This disparity underscores the fact that the GPU is the limiting factor. The benchmark results suggest that any modern mid-range GPU would yield a much better result with this CPU. The combo's rank reflects the overall system capability, and in this case, it is severely hampered by the graphics card. The measured FPS values, which are often below 60 FPS even at 1080p, confirm this assessment.

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

The FPS scaling across resolutions provides clear evidence of the GPU bottleneck. At High settings, the average FPS drops from 50.9 at 1080p to 32.9 at 1440p, a reduction of 35.4%. Moving from 1440p to 4K, the FPS drops further to 19.1, a reduction of 41.9%. This scaling pattern is characteristic of a GPU-limited scenario. As the resolution increases, the number of pixels the GPU must render grows, and the RX 580 simply cannot keep up. The CPU's performance is unaffected by resolution, so if the CPU were the bottleneck, the frame rates would remain similar across resolutions.

The data shows a consistent drop across all settings. For instance, at Low settings, the FPS goes from 85.7 at 1080p to 59.8 at 1440p and then to 33.4 at 4K. This is a clear sign that the GPU is being tasked with more work at each resolution step, and its rendering capabilities are the limiting factor. The 4K results, where even Low settings only achieve 33.4 FPS, confirm that the RX 580 is not capable of handling this game at high pixel counts. The scaling indicates that for this game, resolution is the primary determinant of performance, and the GPU is the component that dictates the playability.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the measured average FPS values are as follows: Low settings yield 85.7 FPS, providing a very smooth experience. Medium settings drop to 63.7 FPS, which is still playable. High settings yield 50.9 FPS, and Ultra settings produce 48.6 FPS. The progression from Low to Ultra shows a steady decline, with the biggest single drop occurring from Low to Medium, a 22.0 FPS difference. This indicates that the Medium preset introduces significantly more graphical load than Low, but the card can handle it. The difference between High and Ultra is smaller, at 2.3 FPS, suggesting diminishing returns at the highest settings.

Moving to 2560x1440, the average FPS values are lower across the board. Low settings achieve 59.8 FPS, which is just shy of a 60 FPS target. Medium settings drop to 44.8 FPS, High to 32.9 FPS, and Ultra to 30.2 FPS. The drop from Low to Medium is 15.0 FPS, and the drop from High to Ultra is 2.7 FPS. At this resolution, the GPU is clearly stressed, with only the Low preset providing a near-playable experience. At 3840x2160, the results are marginal. Low settings yield 33.4 FPS, Medium 24 FPS, High 19.1 FPS, and Ultra 16.4 FPS. None of these are playable for a smooth experience. The data shows that this combination is only viable at 1080p or 1440p Low for a playable frame rate, and the GPU is the definitive bottleneck in all scenarios.
