Thief

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 4090 achieves a combo rank of 79 out of 1642 tested combinations in Thief, placing it in the top 4.8% of all systems benchmarked. This is a dominant position that reflects a pairing capable of maxing out the game’s visual demands, though the data reveals that the GPU is doing the heavy lifting while the CPU remains largely underutilized. The combination’s high percentile ranking is consistent across resolutions, but the performance gaps between settings tiers tell a more nuanced story about where the bottleneck lies.

How This Combo Ranks

The combo ranks 79th overall out of 1,642 tested configurations, a strong result that places it well ahead of the vast majority of systems. This ranking is driven by the RTX 4090’s immense raw throughput; the GPU alone sits in the 91st percentile versus all GPUs, while the i5-12600KF holds an 84th percentile position among CPUs. The average benchmark score for this pairing is 27,827, which is effectively identical to the Intel Core i9-10900K’s 27,829 score (0% delta), indicating that the 12th-gen processor trades blows with a previous flagship in synthetic workloads. Interestingly, the i5-12600K scores 27,851, a negligible 0.1% advantage over this KF variant, and the Core Ultra 5 125H is 0.2% behind, meaning the CPU choice within this tier has virtually no impact on overall system capability.

In actual game performance, the combo’s rank underscores that it is not merely competitive but exceptional. The measured frames per second (FPS) figures at every resolution and settings preset exceed 79 FPS, which is well above the threshold for smooth gameplay. The ranking reflects that only 78 other combinations out of 1,642 deliver higher aggregate performance, evidence of the GPU’s dominance. However, the data also shows that the CPU’s contribution is secondary; its 10 cores and 16 threads are more than sufficient for Thief, a title from 2014 that does not scale heavily with modern multi-core processors.

Settings Recommendations

The optimal settings preset depends on the target resolution, but the data clearly favors Ultra at 1080p and 1440p, with High being the compromise at 4K. At 1920x1080, Ultra delivers 155.4 FPS, which is only 3.1% slower than High’s 160.3 FPS and 9.3% slower than Low’s 190.3 FPS. The visual fidelity gain from Ultra over High is worth the minor FPS drop, especially since even Ultra at 1080p remains far above any refresh-rate ceiling. At 2560x1440, Ultra hits 137.9 FPS, while High reaches 139.9 FPS and Medium 153.3 FPS; the gap between Ultra and High is a mere 1.4%, making Ultra the clear choice for maximum image quality without sacrificing fluidity.

At 3840x2160, the situation changes. Ultra drops to 79.4 FPS, which is still playable but noticeably lower than High’s 83.2 FPS. The difference between Ultra and High at 4K is 4.6%, while Medium offers 112.7 FPS and Low 140.8 FPS. For a 60Hz display, Ultra at 4K is acceptable, but for higher refresh rates, High is the better balance, delivering a 4.8% improvement over Ultra. The data suggests that the GPU’s 24 GB of VRAM and 1.01 TB/s bandwidth are not the limiting factors; instead, the rendering load at 4K Ultra pushes the GPU to its limits, making High the recommended preset for those prioritizing frame rate over marginal settings increases.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear GPU-bound scenario. At High settings, the average FPS drops from 160.3 at 1080p to 139.9 at 1440p (a 12.7% decrease) and then to 83.2 at 4K (a 48.1% decrease from 1080p). This steep drop at 4K is characteristic of a GPU bottleneck, as the RTX 4090’s shading units (16,384) and texture units (512) are saturated by the increased pixel count. The CPU’s role is minimal, as evidenced by the relatively small FPS difference between 1080p and 1440p; the 20.4 FPS gap between these resolutions is far smaller than the 56.7 FPS gap between 1440p and 4K.

At Low settings, the scaling is more linear: 190.3 FPS at 1080p, 168.8 FPS at 1440p (an 11.3% drop), and 140.8 FPS at 4K (a 26.0% drop from 1080p). This pattern indicates that even at Low settings, the GPU remains the primary limiter, though the CPU’s 3.70 GHz base clock and 4.90 GHz boost clock are sufficient to avoid becoming a constraint. The data shows that the RTX 4090’s 82.58 TFLOPS of FP32 performance is the dominant factor; the i5-12600KF’s 20 MB of shared L3 cache and 10 cores are never the bottleneck, as evidenced by the consistent FPS gains from 4K to 1080p at all settings.

Measured FPS Breakdown

At 1920x1080, the average FPS ranges from 155.4 at Ultra to 190.3 at Low. Medium delivers 171.4 FPS, and High reaches 160.3 FPS. The spread between Low and Ultra is 34.9 FPS, or 18.3% of Low’s score, indicating that the GPU has ample headroom even at maximum settings. At 2560x1440, the numbers shift: Low hits 168.8 FPS, Medium 153.3 FPS, High 139.9 FPS, and Ultra 137.9 FPS. The difference between High and Ultra here is only 2.0 FPS, showing that the Ultra preset adds minimal overhead at this resolution.

At 3840x2160, the averages are 140.8 FPS for Low, 112.7 FPS for Medium, 83.2 FPS for High, and 79.4 FPS for Ultra. The gap between Medium and High is 29.5 FPS, which is the largest single-preset jump across all resolutions, highlighting that High settings at 4K impose a significant rendering cost. The progression from Low to Ultra at 4K shows a 61.4 FPS drop, or 43.6% of Low’s score, which is nearly double the percentage drop seen at 1080p. This demonstrates that the GPU’s 24 GB GDDR6X memory and 384-bit bus width are being fully exercised at 4K, with the 1.01 TB/s bandwidth becoming a critical resource.

GPU Role

The NVIDIA GeForce RTX 4090 is the undisputed performance driver in this combo. Its 24 GB of GDDR6X memory on a 384-bit bus provides 1.01 TB/s of bandwidth, which is essential for maintaining high frame rates at 4K Ultra, where the game’s textures and shadows demand substantial memory throughput. The GPU’s boost clock of 2520 MHz and base clock of 2235 MHz support its 82.58 TFLOPS of FP32 compute, enabling the high FPS figures observed. The data shows that the GPU’s 91st percentile ranking versus all GPUs is well-earned, as its average benchmark score of 66,473 is competitive with the NVIDIA Tesla T4 (66,733, -0.4%), though it trails the AMD Radeon Pro Vega 56 (67,097, -0.9%).

In Thief specifically, the GPU’s pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s are the key enablers of the measured FPS. At 4K High, the 83.2 FPS result indicates that the GPU is processing roughly 331 million pixels per second, well within its theoretical limits. However, at 4K Ultra, the 79.4 FPS score shows that the extra settings push the GPU closer to its ceiling, as the 16,384 shading units are fully occupied. The GPU’s 128 RT cores and 512 tensor cores are not directly relevant to Thief’s non-ray-traced rendering, but they contribute to the card’s overall benchmark scores, reinforcing its top-tier status.

CPU Role

The Intel Core i5-12600KF plays a supportive but non-limiting role in this combo. Its 10 cores (6 performance + 4 efficiency) and 16 threads operate at a base clock of 3.70 GHz and boost to 4.90 GHz, providing ample single-threaded and multi-threaded capability for Thief, a title released in 2014. The CPU’s 20 MB of shared L3 cache and 1.25 MB per-core L2 cache ensure that game logic and AI calculations are handled without stutter, but the benchmark data shows that the GPU is the primary driver of FPS. The CPU’s average benchmark score of 27,827 places it in the 84th percentile of all CPUs, yet this performance headroom is largely unused in this game, as the FPS scales directly with resolution and settings, a hallmark of GPU limitation.

The CPU’s nearest rivals include the Intel Core i9-10900K (27,829, 0% delta), i5-12600K (27,851, -0.1% delta), and Core Ultra 5 125H (27,872, -0.2% delta), all of which would perform identically in Thief. This is because the game’s engine does not leverage the i5-12600KF’s 16 threads to a significant degree; the 3DMark scores show a single-thread score of 1,016 and an 8-thread score of 6,128, indicating that the CPU’s strength lies in multi-threaded workloads that Thief does not heavily utilize. The 125W TDP and Intel Socket 1700 platform are irrelevant to in-game FPS, but they confirm that this is a desktop-class processor with sufficient power delivery for sustained loads. Ultimately, the data indicates that swapping this CPU for any of its nearest rivals would yield no measurable change in Thief’s frame rates, cementing the RTX 4090 as the sole determinant of performance.
