Thief

This combo of the Intel Core i9-14900K and the AMD Radeon RX 6750 XT is a high-end pairing that yields a solid performance tier for Thief, though the game's age means the CPU is rarely the limiting factor. The combination ranks 726th out of 1,642 tested combos for this title, placing it in the upper-middle portion of the database. This position is largely determined by the GPU, which sits at the 79th percentile among all tested graphics cards, while the CPU is far more powerful, ranking in the 97th percentile among all CPUs. The data indicates a significant imbalance, with the GPU acting as the primary bottleneck in most scenarios, particularly at higher resolutions.

How This Combo Ranks

The overall rank of 726 out of 1,642 combos suggests that while this pairing is capable of delivering smooth gameplay, it is not at the absolute top tier for Thief. This is a direct consequence of the GPU's standing; the Radeon RX 6750 XT holds the 79th percentile among all GPUs, which is respectable but not flagship-level. In contrast, the Core i9-14900K's 97th percentile ranking shows it is a top-tier processor. The performance delta between the GPU and its nearest rivals is minimal, with the RX 6750 XT's average benchmark score of 35,327 being only 0.2% higher than the AMD Radeon RX 5600M and 1.3% lower than the NVIDIA GeForce RTX 3080. This indicates that the RX 6750 XT is competitive within its performance class, but the i9-14900K has substantial headroom that this game cannot fully utilize.

The benchmark results for the CPU show its immense capability, with a Cinebench R23 multi-core score of 49,872 and a single-core score of 7,040. In the context of Thief, a title from 2014, such processing power is vastly more than sufficient. The CPU's nearest rivals, such as the AMD EPYC 7413 and the Intel Core i9-14900KF, post average scores within 0.7% of this chip, confirming that the i9-14900K is at the peak of consumer performance. However, the in-game FPS data tells the story of a system held back by its graphics solution, especially as resolution increases.

Settings Recommendations

The measured FPS data reveals that the optimal experience depends heavily on the target resolution. At 1080p, the system has ample performance to run the game at its highest preset. The Ultra preset delivers an average of 107.1 FPS, and the High preset achieves 112.9 FPS, both well above the threshold for smooth, responsive gameplay. The data shows that at this resolution, the CPU is not a bottleneck, and the GPU can handle even the most demanding settings with ease. For a 1080p display, the Ultra preset is clearly the best choice, offering the highest visual fidelity without sacrificing frame rate.

Moving to 1440p, the situation becomes more nuanced. The Ultra preset still delivers a playable 71.8 FPS, but the High preset provides a more comfortable margin at 76 FPS. The Medium preset jumps to 100.4 FPS, which is ideal for high-refresh-rate monitors. Given that the GPU is the limiting factor here, choosing between High and Medium is a trade-off between visual quality and frame rate headroom. For most users, the High preset at 1440p offers the best balance, maintaining a solid average FPS while preserving most of the game's graphical features. At 4K, the GPU is clearly overburdened, and the Ultra preset drops to 43.7 FPS, which is often considered the edge of playability. The High preset is only marginally better at 47.2 FPS, so players seeking a consistent experience at this resolution would need to consider the Medium preset at 61.5 FPS or the Low preset at 76.7 FPS.

Resolution Scaling

The performance scaling across resolutions clearly identifies the GPU as the primary constraint. At 1080p with the High preset, the system achieves 112.9 FPS. This drops to 76 FPS at 1440p, a 32.7% reduction, and then to 47.2 FPS at 4K, a further 37.9% decline from the 1440p figure. This pattern is consistent with a GPU-bound scenario; the rendering load increases exponentially with pixel count, and the RX 6750 XT, with its 12 GB of VRAM and 432.0 GB/s of bandwidth, simply runs out of processing power.

The data suggests that the i9-14900K is not a limiting factor at any resolution. The FPS drop from 1080p to 1440p is significant, and the drop to 4K is even more pronounced, which is characteristic of a graphics card that is saturated. If the CPU were the bottleneck, we would expect to see similar frame rates across resolutions, or at least a much smaller performance delta. Instead, the scaling indicates that the GPU is working at its maximum capacity, and the resolution is the primary variable affecting performance. This is a textbook example of a high-end CPU paired with a mid-range GPU, where the latter defines the system's gaming performance ceiling.

Measured FPS Breakdown

At 1920x1080, the system demonstrates excellent performance across all settings. The Low preset yields an average of 195.5 FPS, which is exceptionally high and suggests the game is not taxing the hardware at all. The Medium preset achieves 147 FPS, while the High preset reaches 112.9 FPS. The Ultra preset is still highly playable at 107.1 FPS. The scaling from Low to Ultra shows a 45.2% drop in performance, which is typical for a game that scales well with graphical fidelity. The high frame rates at this resolution suggest that the GPU is not fully utilized, and there is headroom for even higher refresh rates.

At 2560x1440, the performance remains strong but begins to show the GPU's limits. The Low preset delivers 131.8 FPS, which is still very smooth. The Medium preset drops to 100.4 FPS, and the High preset falls to 76 FPS. The Ultra preset is the most demanding, yielding 71.8 FPS. The difference between Low and Ultra is a 45.5% reduction, mirroring the scaling seen at 1080p. The fact that the Ultra preset at 1440p is still above 60 FPS shows that this is a capable pairing for most gaming scenarios.

At 3840x2160, the performance drops significantly, confirming the GPU is the bottleneck. The Low preset manages 76.7 FPS, which is acceptable. The Medium preset achieves 61.5 FPS, and the High preset drops to 47.2 FPS. The Ultra preset is the most demanding, with an average of just 43.7 FPS. The scaling from Low to Ultra shows a 43.0% reduction in performance. The data indicates that this combination is not ideal for 4K gaming on high settings, as the frame rates dip below the 60 FPS threshold. Players wanting to play at 4K would need to use lower presets to maintain smooth gameplay.

GPU Role

The AMD Radeon RX 6750 XT plays the decisive role in this gaming configuration. Its 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, which is sufficient for a 2014 title like Thief, but the GPU's raw compute power is the limiting factor. The card has a base clock of 2150 MHz and a boost clock of 2600 MHz, with a game clock of 2495 MHz. Its 2,560 shading units, 160 TMUs, and 64 ROPs deliver a peak FP32 performance of 13.31 TFLOPS. These specifications place it in the 79th percentile of all GPUs, and its benchmark scores reflect this, with a 3DMark Steel Nomad DX12 score of 2,548 and a Passmark G3D score of 20,700.

The GPU's performance relative to its nearest rivals is tight. Its average benchmark score of 35,327 is only 0.2% higher than the AMD Radeon RX 5600M and 1.3% lower than the NVIDIA GeForce RTX 3080. This means the RX 6750 XT is positioned in a highly competitive segment, and its in-game performance is typical for this class. The measured FPS data confirms that the GPU is the primary determinant of frame rate, especially at higher resolutions. The i9-14900K, with its 24 cores and 32 threads, is vastly over-provisioned for this game, and its high clock speeds and large cache are irrelevant to the performance observed. The GPU's 250 W TDP and dual-slot design are standard for its class, and it requires a 600 W power supply. The card's 40 ray tracing cores are present, but Thief does not utilize ray tracing, so they have no impact on the measured results. In summary, the RX 6750 XT is the component that dictates the gaming experience, and its mid-range standing is the reason this combo ranks 726th rather than higher.
