Thief

The Intel Core i5-14600KF and AMD Radeon RX 6600 pairing delivers a playable but heavily resolution-dependent experience in Thief. The data shows a clear narrative: at 1080p, the system is capable of high refresh rates, but 4K Ultra pushes the GPU to its absolute limit, resulting in framerates that barely clear 30 FPS. This is a classic mid-range combination where the RX 6600 is the primary bottleneck at higher resolutions, while the robust 14-core CPU ensures the processor is never the limiting factor.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and reveals a GPU-bound system. At 1080p with Low settings, the combo averages 141.5 FPS. Scaling to 1440p Low drops that to 97 FPS, a reduction of 44.5 FPS. Moving to 4K Low yields 60.3 FPS, which is less than half the 1080p figure. This steep decline indicates that the Radeon RX 6600’s rendering throughput is the primary constraint as pixel count increases.

The scaling pattern holds across all quality presets. On High settings, the average FPS falls from 83.9 at 1080p to 58.5 at 1440p and finally to 32 at 4K. The 4K High result is a 61.9% drop from the 1080p High score. This consistent, sharp decline with each resolution step confirms that the GPU’s 8 GB of VRAM and 224.0 GB/s bandwidth are being saturated, not the CPU’s capabilities. The 1080p to 1440p transition is the most forgiving, while the 1440p to 4K jump is brutal, often cutting performance by more than 40%.

The data suggests that the "sweet spot" for this pairing is 1440p. At this resolution, the system maintains respectable averages of 97 FPS on Low and 58.5 FPS on High, making it a viable target for smooth gameplay. At 4K, only the Low preset achieves a playable average of 60.3 FPS, while Medium (43.7 FPS) and High (32 FPS) fall below the 60 FPS threshold. For users targeting 4K, the benchmark results indicate that significant settings compromises are necessary.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor based on the Raptor Lake architecture. Its configuration includes a base clock of 3.50 GHz and a boost clock of 5.30 GHz. This high boost clock, combined with 24 MB of shared L3 cache, provides substantial single-thread performance, which is critical for a 2014 stealth title like Thief that may not be heavily multithreaded. The CPU’s PassMark single-thread score of 4273 and Cinebench R23 single-core score of 4643 demonstrate strong per-core capability.

In this game’s benchmark results, the CPU’s role appears to be supportive rather than dominant. The fact that average framerates scale down so predictably with resolution suggests the processor is not a bottleneck. The i5-14600KF’s multi-threaded might, evidenced by a Cinebench R23 multi-core score of 32889, is largely idle headroom in this scenario. The CPU’s performance percentile of 93 among all CPUs further reinforces that it is a high-tier part.

The processor’s specifications align with the results. With a 125 W TDP and support for DDR4 or DDR5 memory, it is a flexible platform. The benchmark shows that even at 1080p Low, where the CPU load is highest relative to the GPU, the system reaches 141.5 FPS. This suggests the CPU can feed the GPU adequately at high framerates. In a game like Thief, which relies on physics and AI for stealth mechanics, the 20 threads provide ample headroom for background tasks and game logic without impacting the frame rate.

GPU Role

The AMD Radeon RX 6600 is the decisive factor in this pairing. Built on the RDNA 2.0 architecture with a 7 nm process, it features 1792 shading units and 64 ROPs. Its boost clock of 2491 MHz and game clock of 2044 MHz are high for its class. However, the 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth, is a limiting factor for high-resolution textures. The GPU’s PassMark G3D score of 15096 places it in the 69th percentile of all GPUs, indicating a solid mid-range part.

The measured FPS data shows the RX 6600 struggling at 4K. The Ultra preset at 3840x2160 yields an average of just 31.5 FPS, while High is only marginally better at 32 FPS. This indicates that the GPU’s compute throughput and memory bandwidth are exhausted. At 1440p, the GPU performs more comfortably, with Medium settings hitting 76.3 FPS. The jump from 1440p to 4K represents a near doubling of pixel count, which directly correlates with the observed performance halving.

The GPU’s 8 GB VRAM is likely a factor at 4K Ultra, where texture data can exceed this capacity. While the benchmark does not provide VRAM usage, the significant drop from Medium (43.7 FPS) to High (32 FPS) at 4K suggests that increased texture detail and shading effects are taxing the memory subsystem. The RX 6600’s performance is consistent with its position between rivals like the AMD Radeon 890M and NVIDIA GeForce RTX 3060 Ti in aggregate benchmarks, but in this specific title, its 4K performance is the bottleneck.

Measured FPS Breakdown

At 1920x1080, the system provides a wide range of performance. Low settings produce an average of 141.5 FPS, which is excellent for high-refresh-rate monitors. Medium settings drop to 110 FPS, still very smooth. High settings yield 83.9 FPS, and Ultra pulls 76.5 FPS. All 1080p presets are above 75 FPS, showing that the CPU and GPU combo is well-balanced for this resolution.

Moving to 2560x1440, the averages are still respectable but show the GPU’s strain. Low settings achieve 97 FPS, Medium hits 76.3 FPS, and High falls to 58.5 FPS. Ultra is the only preset to dip below the 60 FPS target, with an average of 55.8 FPS. This resolution represents the practical limit for high-quality settings without compromise.

At 3840x2160, the results are heavily constrained by the GPU. Low settings average 60.3 FPS, which is just playable. Medium drops to 43.7 FPS, High is 32 FPS, and Ultra is 31.5 FPS. The difference between High and Ultra at 4K is negligible (0.5 FPS), indicating that the GPU is completely saturated. The data clearly shows that 4K gaming with this pairing requires the Low preset for a playable experience, or a significant reduction in graphical fidelity.
