# Thief with Intel Core i9-14900K + NVIDIA GeForce RTX 5080

The pairing of Intel's 24-core Core i9-14900K with NVIDIA's Blackwell-based RTX 5080 produces a fascinating benchmark story in Thief, a 2014 stealth title that still demands careful analysis. This combination sits at rank 14 out of 1,642 tested combos, placing it in the top 1% of all configurations measured. The data reveals a system that is heavily GPU-bound at higher resolutions, yet shows surprising CPU headroom at 1080p, where the frame rates approach what many would consider the practical ceiling for this engine.

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

The Intel Core i9-14900K brings substantial processing resources to this pairing: 24 cores and 32 threads running on the Raptor Lake architecture, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. The CPU's 36 MB of shared L3 cache and 2 MB per-core L2 cache provide ample data locality for game logic, though Thief's stealth-focused gameplay likely doesn't stress all 24 cores equally.

Benchmark data places this CPU in the 97th percentile among all processors, with an average benchmark score of 79,824. Its nearest rivals include the AMD EPYC 7413 (scoring 80,041, a -0.3% delta) and the Intel Core i9-14900KF (79,245, +0.7% delta), showing the i9-14900K sits in a tightly contested performance band. The single-core Cinebench R23 score of 7,040 and multicore score of 49,872 indicate strong per-thread performance, which matters for game engines that rely on a few primary threads.

In Thief specifically, the CPU appears to be a limiting factor only at the lowest resolution and settings. At 1080p Low, the system achieves 227.9 FPS, but the gap between Low and Ultra settings at 1080p is only 40.7 FPS (227.9 vs 187.2), suggesting that the CPU can feed the GPU sufficiently across all settings at this resolution. The 24-core configuration provides significant headroom, even if the game itself may not utilize all threads efficiently.

How This Combo Ranks — use comboRankInGame vs other tested combos

This configuration's rank of 14 out of 1,642 tested combos places it in the 99.1st percentile of all measured systems. The data indicates that only 13 other combinations deliver higher average frame rates across the tested scenarios. This high ranking is notable given that Thief is a title from 2014, and the combination of a 2023 CPU with a 2025 GPU demonstrates how modern hardware can push older engines to their limits.

The ranking reflects the sum of the CPU's 97th percentile standing and the GPU's 89th percentile positioning. While the RTX 5080 is not the absolute top-tier GPU in the database, the i9-14900K's strong single-thread performance helps ensure that the GPU is not starved for data at lower resolutions. The delta between this combo and the top-ranked systems likely stems from GPUs with higher raw throughput, but the data shows this pairing still outperforms the vast majority of alternatives.

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

The scaling pattern across resolutions reveals a system that transitions from CPU-leaning to GPU-limited as pixel count increases. At High settings, the average FPS drops from 187.7 at 1080p to 136.1 at 1440p (a 27.5% decrease) and then to 82.2 at 4K (a further 39.6% decrease from 1440p). This steep decline at 4K indicates that the RTX 5080 becomes the primary bottleneck at higher resolutions, while the CPU's influence diminishes.

At Low settings, the scaling is even more dramatic: 227.9 FPS at 1080p falls to 200.7 at 1440p (-11.9%) and then to 137.9 at 4K (-31.3% from 1440p). The relatively modest drop from 1080p to 1440p at Low settings suggests the CPU is still able to maintain high frame delivery, but the 4K result shows the GPU struggling to keep pace with the CPU's output. The Ultra settings curve tells a similar story: 187.2 FPS at 1080p, 130.2 at 1440p (-30.4%), and 74.7 at 4K (-42.6% from 1440p).

The pattern across all settings indicates that at 4K, the GPU is the clear limiting factor, with the CPU's role diminishing as resolution increases. At 1080p, the system appears more balanced, with the CPU's strong single-thread performance helping to maintain high frame rates even at Ultra settings.

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

At 1920x1080, the measured frame rates show a narrow band across settings: Low delivers 227.9 FPS, Medium 205.4 FPS, High 187.7 FPS, and Ultra 187.2 FPS. The difference between High and Ultra is negligible (only 0.5 FPS), suggesting that the Ultra preset adds visual features that have minimal performance impact at this resolution.

Moving to 2560x1440, the spread widens: Low produces 200.7 FPS, Medium 179.5 FPS, High 136.1 FPS, and Ultra 130.2 FPS. The gap between Medium and High at 1440p is 43.4 FPS, indicating that the High preset introduces significant rendering costs. The Ultra preset at 1440p delivers 130.2 FPS, which is still well above the 60 FPS threshold for smooth gameplay.

At 3840x2160, the performance hierarchy tightens: Low achieves 137.9 FPS, Medium 103.6 FPS, High 82.2 FPS, and Ultra 74.7 FPS. The 4K results show the most significant performance penalties, with Ultra delivering less than half the frame rate of 1080p Ultra. The data shows that even at 4K Ultra, the system maintains playable frame rates, but the margin above 60 FPS narrows considerably.

Settings Recommendations

The measured data points to 1440p as the optimal resolution for this pairing. At 2560x1440, the Ultra preset delivers 130.2 FPS, which is well above the 60 FPS standard for smooth gameplay and only 6 FPS less than High settings (136.1 FPS). The 6 FPS difference between High and Ultra at 1440p is a reasonable trade for the visual improvements that Ultra typically provides.

For players prioritizing maximum frame rates, 1080p Low delivers 227.9 FPS, which may be beneficial for competitive play or high-refresh-rate displays. However, the 40.7 FPS gap between Low and Ultra at 1080p (227.9 vs 187.2) suggests that Ultra at 1080p still provides excellent performance at 187.2 FPS.

At 4K, the Medium preset at 103.6 FPS offers the best balance between visual fidelity and performance. The High preset at 82.2 FPS and Ultra at 74.7 FPS remain playable, but the step from Medium to High costs 21.4 FPS, making Medium the recommended choice for 4K. The Low preset at 137.9 FPS is the only 4K option that maintains triple-digit frame rates, but it sacrifices significant visual quality.
