Thief

The Intel Core i5-14600KF paired with the AMD Radeon RX 6650 XT delivers a solid, if not spectacular, experience in Thief, with the data showing that the Ultra preset is largely a trap at higher resolutions. The sweet spot for this combination is the High preset at 1440p, which balances the GPU's 8 GB frame buffer and the CPU's strong single-thread performance to produce a playable and visually consistent 61.6 FPS average. At 1080p, the High preset achieves a smooth 95.6 FPS, but the jump to Ultra at that resolution only yields a 9% reduction in frame rate, suggesting the CPU is still holding the reins. The data indicates that pushing to 4K on any preset except Low will result in sub-60 FPS averages, making High at 1440p the definitive recommendation for this pairing.

Settings Recommendations

The measured FPS rows show a clear hierarchy in performance scaling, and the optimal preset depends heavily on the target resolution. At 1920x1080, the Medium preset delivers 123.9 FPS, which is a 29.6% improvement over High's 95.6 FPS, while the visual difference between Medium and High is typically much smaller than the performance gap. For competitive or high-refresh-rate play, Low at 1080p offers 161.5 FPS, but the jump from Low to Medium costs 23.3% of that performance, indicating a significant GPU workload increase. However, the most balanced experience is at 2560x1440 with the High preset, producing 61.6 FPS—this is the only 1440p setting above 60 FPS besides Low. The Ultra preset at 1440p drops to 62.8 FPS, which is only 1.9% faster than High, making Ultra a poor choice as it likely adds minimal visual fidelity for no measurable frame rate gain. At 4K, the data strongly advises against anything above Low, as the High preset yields just 38.9 FPS, and Ultra falls to 37.6 FPS, both of which are below acceptable playability thresholds. The recommendation is clear: use High at 1440p for the best combination of image quality and performance, or drop to Medium at 1080p if a higher frame rate is prioritized.

CPU Role

The Intel Core i5-14600KF brings 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz, which is a substantial amount of processing power for a 2014 title like Thief. The CPU's benchmark data shows a Cinebench R23 multi-core score of 32889 and a single-core score of 4643, placing it in the 93rd percentile among all CPUs. This single-thread strength is critical for Thief, a game that relies heavily on CPU-bound game logic and AI. The data reveals this dependency through the frame rate scaling at 1080p: from Low to Ultra, the average FPS drops from 161.5 to 87, a 46.1% reduction, but the CPU is still able to push past 87 FPS even at Ultra, showing it is not the bottleneck at that resolution. However, at 1440p, the CPU's influence wanes, as the FPS drop from Low to Ultra is 42.5% (from 109.2 to 62.8), which is a smaller relative decline than at 1080p, indicating the GPU is starting to take over the limiting role. The CPU's 24 MB of L3 cache and 2 MB per-core L2 cache help maintain consistent frame pacing, as evidenced by the lack of any reported minimum FPS dips in the data. The processor's performance relative to its nearest rivals—0.4% ahead of the Core i5-14600K and 0.6% ahead of the Ryzen 9 5950X—confirms it is not leaving performance on the table in CPU-limited scenarios.

GPU Role

The AMD Radeon RX 6650 XT is the primary limiting factor in this pairing at higher resolutions, and its 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s of bandwidth is the key constraint. The GPU's boost clock of 2635 MHz and game clock of 2410 MHz are high for the RDNA 2.0 architecture, but the 10.79 TFLOPS of FP32 performance is modest by modern standards. This is reflected in the benchmark results, where the GPU scores 17166 in Passmark G3D, placing it in the 72nd percentile. In Thief, the GPU's role becomes apparent when examining the 4K results: the High preset averages 38.9 FPS, and Ultra drops to 37.6 FPS, a mere 3.3% difference, while the jump from Low to Medium at 4K costs 22.0% of performance (from 67.2 to 52.4 FPS). This non-linear scaling suggests the 8 GB frame buffer is exhausted at 4K Ultra, causing a hard performance ceiling. At 1440p, the GPU handles the load better, but the Ultra preset at 62.8 FPS is only 2% faster than High's 61.6 FPS, indicating that the GPU is hitting a memory bandwidth wall rather than a compute limit. The GPU's nearest rivals—the RX 6800M, RX 470, and Intel Arc A370M—are all within 0.6% of its average benchmark score, confirming it is a mid-range part that cannot sustain high settings at 4K without significant compromises.

How This Combo Ranks

This specific combination of the Core i5-14600KF and Radeon RX 6650 XT ranks 1020 out of 1642 tested combos in Thief, placing it in the 62nd percentile of all possible pairings. This ranking is notably lower than the individual components' percentiles (93rd for CPU, 72nd for GPU), which indicates that the pairing is not optimally balanced for this game—the GPU is dragging down the overall result. The data shows that the CPU is capable of much higher frame rates, as evidenced by the 161.5 FPS at 1080p Low, but the GPU cannot maintain that pace at higher settings. Compared to other combos, this rank suggests that a weaker CPU with a stronger GPU would likely score better in Thief, as the game is more GPU-bound at the resolutions where this combo struggles. The rank of 1020 out of 1642 means 622 other combinations perform better, which is a significant number, but it also means 380 combos perform worse, so this is not a bottom-tier setup. The benchmark results indicate that the combo is well-suited for 1080p and 1440p gaming at medium-to-high settings, but it falls behind in 4K scenarios where the GPU's limitations are exposed.

Resolution Scaling

The FPS data reveals a dramatic scaling pattern from 1080p to 4K, which clearly identifies the GPU as the bottleneck at higher resolutions. When moving from 1920x1080 to 2560x1440 on the High preset, the average FPS drops from 95.6 to 61.6, a 35.6% reduction. Scaling further to 3840x2160 at High, the FPS falls to 38.9, which is a 59.3% drop from 1080p. This scaling is not linear—the pixel count increases by 2.25x from 1080p to 4K, but the FPS drops by only 59.3%, suggesting that the CPU is still providing some headroom at 4K Low (which achieves 67.2 FPS). The Low preset shows the least degradation: from 161.5 FPS at 1080p to 109.2 at 1440p (32.4% drop) to 67.2 at 4K (58.4% drop from 1080p). This pattern indicates that the GPU's compute units are saturated at 4K, but the memory subsystem is the true limiter—the 280.3 GB/s bandwidth is insufficient for 4K textures. The Ultra preset shows the most severe scaling, with a 56.8% drop from 1080p (87 FPS) to 4K (37.6 FPS), which is consistent with the GPU running out of both compute and memory resources. The data conclusively shows that this combo is not viable for 4K gaming beyond Low settings, and the limiting component shifts from the CPU at 1080p to the GPU at 1440p and above.

|------------|----------|-------------|

| 3840x2160 | High | 38.9 |

| 3840x2160 | Low | 67.2 |

| 3840x2160 | Medium | 52.4 |

| 3840x2160 | Ultra | 37.6 |

| 2560x1440 | High | 61.6 |

| 2560x1440 | Low | 109.2 |

| 2560x1440 | Medium | 85.9 |

| 2560x1440 | Ultra | 62.8 |

| 1920x1080 | High | 95.6 |

| 1920x1080 | Low | 161.5 |

| 1920x1080 | Medium | 123.9 |

| 1920x1080 | Ultra | 87.0 |

The data shows that the Medium preset at 1440p (85.9 FPS) is the highest setting that maintains a 60+ FPS average at that resolution, while at 1080p, even Ultra (87 FPS) remains comfortably playable. The Ultra preset's performance at 4K (37.6 FPS) is nearly identical to High (38.9 FPS), a 3.3% difference that suggests the GPU is completely saturated. Conversely, the jump from Medium to High at 1080p costs 22.8% of performance (from 123.9 to 95.6 FPS), which is a larger relative drop than the 4K Ultra-to-High comparison, highlighting how the CPU mitigates GPU load at lower resolutions. The 1440p results show a more gradual scaling, with Medium (85.9) to High (61.6) representing a 28.3% reduction, and High to Ultra (62.8) showing a negligible 1.9% increase, which is likely measurement variance rather than a real performance gain.
