Thief

The Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 4090 delivers a fascinating performance profile in Thief, a 2014 stealth title that remains surprisingly demanding at high resolutions. The data shows a system with immense headroom, where the GPU is the primary bottleneck at 4K, but the CPU’s strong single-threaded performance ensures that even at lower resolutions, frame rates remain exceptionally high. This combination ranks in the top 2% of all tested combos, making it a formidable setup for this classic title.

Resolution Scaling

The measured FPS data reveals a clear and predictable scaling pattern as resolution increases, with the most dramatic drop occurring between 1440p and 4K. At 1080p with High settings, the system produces an average of 170.7 FPS. Moving to 1440p High, the average dips slightly to 145.3 FPS, a modest reduction of about 15% that suggests the GPU is still comfortably handling the workload. However, the jump to 4K High tells a different story: the average FPS plummets to 83.4, a massive 43% drop from the 1440p figure. This sharp decline at 4K strongly indicates that the NVIDIA GeForce RTX 4090 is hitting its rendering limits, and the game’s visual fidelity at this resolution is placing an immense burden on the graphics card.

The pattern becomes even more pronounced when examining the Low preset. At 1080p Low, the system achieves a staggering 207.1 FPS, which only falls to 184.1 FPS at 1440p. But at 4K Low, the average collapses to 146.3 FPS. While this is still a very playable frame rate, the scaling from 1440p to 4K shows a 20% reduction, confirming that even with minimal graphical load, the 4K resolution is the defining factor. The RTX 4090’s 24 GB of GDDR6X memory and 1.01 TB/s of bandwidth are sufficient, but the sheer pixel count at 3840x2160 is what drives the performance cost.

The data suggests that at 1080p and 1440p, the Intel Core i5-14600KF is often the limiting component, especially on lower presets. The 14 cores and 20 threads, with a boost clock of 5.30 GHz, are more than capable, but the engine’s single-threaded nature in a 2014 title means that raw CPU speed caps out before the GPU is fully utilized. At 4K, however, the bottleneck shifts decisively to the GPU. The RTX 4090’s average FPS at 4K Ultra is 78.9, which is only 10% slower than 4K High (83.4 FPS), showing that the GPU is saturated and additional graphical features have diminishing returns. This is classic GPU-bound behavior, where the resolution has a far greater impact than the preset level.

Settings Recommendations

Based on the measured rows, the optimal balance of visual quality and performance for this combo depends heavily on the target resolution. For 4K gaming, the High preset is the clear winner. It delivers an average of 83.4 FPS, which is just 4.5 FPS higher than the Ultra preset’s 78.9 FPS. The difference between High and Ultra is minimal in performance terms, but High provides a significant boost over Medium, which only reaches 108.9 FPS. Since the GPU is the bottleneck at 4K, choosing High over Ultra is a sensible trade-off that preserves most of the visual fidelity while keeping the frame rate comfortably above 80 FPS.

At 1440p, the story changes. Here, the system has more headroom, and the Ultra preset becomes a viable option. The data shows 138.1 FPS at 1440p Ultra, which is only 7.2 FPS less than High’s 145.3 FPS. Given that the CPU is more of a factor at this resolution, the slight performance cost of Ultra is well worth it for the enhanced detail. For players seeking maximum smoothness, the Medium preset at 1440p offers 168.7 FPS, but this sacrifices visual quality for a frame rate that exceeds the refresh rate of most standard monitors.

At 1080p, the system is overwhelmingly CPU-bound on most presets. The Ultra preset achieves 170.2 FPS, while High achieves 170.7 FPS, a negligible difference. The Medium preset pushes to 190.1 FPS, and Low reaches 207.1 FPS. Since the CPU is the limiting factor at this resolution, upgrading from High to Ultra costs almost nothing in performance. Therefore, the Ultra preset is the recommended choice for 1080p, as it provides the best visual experience without any meaningful FPS penalty. The Low preset is only useful for extreme competitive play, but the gains are marginal compared to the loss in graphical fidelity.

CPU Role

The Intel Core i5-14600KF plays a crucial role in this combo, particularly at lower resolutions where its performance dictates the upper FPS ceiling. This processor, built on the Raptor Lake architecture with a 10 nm process, features 14 cores and 20 threads. Its base clock of 3.50 GHz and boost clock of 5.30 GHz are key assets for Thief, a game that heavily relies on strong single-threaded performance. In synthetic benchmarks, the CPU scores 4,643 points in Cinebench R23 single-core and 2,778 points in Geekbench single-core, which are indicative of its excellent per-core strength.

The data shows that at 1080p Low, the system hits 207.1 FPS, but at 1080p High, it only drops to 170.7 FPS. This relatively small drop suggests that the CPU is holding the system back, preventing the RTX 4090 from pushing even higher frame rates. The 5.30 GHz boost clock is likely the reason why the system can exceed 200 FPS at all; without this high clock speed, the results would be lower. The CPU’s 24 MB of shared L3 cache also helps in feeding the GPU with data, reducing potential stutters.

When compared to its nearest rivals, the i5-14600KF shows a 0.4% higher average benchmark score than the Intel Core i5-14600K, and a 0.6% advantage over the AMD Ryzen 9 5950X. While these differences are small in synthetic tests, they can translate to a few extra FPS in a CPU-bound scenario like 1080p in Thief. The CPU’s performance percentile of 93 vs all CPUs places it in the top tier, confirming that it is not a weak link in this configuration. However, the data clearly shows that at 4K, the CPU’s role diminishes, and the RTX 4090 becomes the sole determinant of performance.

How This Combo Ranks

Looking at the broader database of tested combinations, this pairing of the Intel Core i5-14600KF and NVIDIA GeForce RTX 4090 achieves a rank of 32 out of 1,642 combos in Thief. This places it in the top 2% of all systems tested, which is an exceptional result. The ranking reflects the synergy between a high-end CPU and the flagship GPU, even if the game is nearly a decade old. The combo’s performance is strong enough to dominate the leaderboard, though it is not the absolute fastest, as there are 31 other configurations that produce higher average FPS.

The ranking is particularly impressive given that the RTX 4090 is listed as end-of-life and has a successor in the GeForce 50 series. Despite this, its 91st percentile ranking among all GPUs, alongside the CPU’s 93rd percentile, results in a top-tier gaming experience. The data indicates that the bottleneck at 4K is the GPU, so any combo ranked above this one likely uses a more powerful or more specialized graphics solution. At 1440p and below, the CPU’s strong showing ensures that the system remains competitive with any other pairing.

The deltaPct values for the CPU’s nearest rivals are minimal, with the i5-14600KF being 0.4% faster than the i5-14600K and 1.4% faster than the Intel Xeon Gold 5318H. These small margins suggest that the CPU choice has little impact on the final rank, and the GPU is the primary driver of the combo’s position. For users looking to replicate this performance, the data confirms that a top-tier CPU is necessary to avoid leaving performance on the table at lower resolutions, but the GPU is the star of the show at 4K.
