Thief

Thief is a 2014 stealth title that remains remarkably playable on this Intel Core i5-12400 + NVIDIA GeForce RTX 4060 pairing, but the data reveals a clear tension between visual fidelity and frame rate consistency. At 1080p, the combo delivers excellent performance across all settings, yet the transition to 4K exposes the GPU's limits. The benchmark results indicate that the optimal experience hinges on resolution: at 1440p and below, Ultra settings are viable; at 4K, a drop to Medium is necessary to maintain playable fluidity.

Settings Recommendations

The measured FPS data strongly suggests that the Ultra preset is the best choice for 1080p and 1440p gaming. At 1920x1080, Ultra delivers 104.9 FPS average, which is only a 3% reduction from High (108 FPS) and a 26% drop from Medium (142.3 FPS). This narrow gap between High and Ultra at 1080p indicates that the visual enhancements of Ultra come at a negligible performance cost relative to the baseline. Similarly, at 2560x1440, Ultra achieves 72.9 FPS, which is nearly identical to High's 72.4 FPS (a 0.7% difference), making Ultra the superior choice for image quality without sacrificing smoothness.

For 4K (3840x2160), the situation changes dramatically. Ultra drops to 44.2 FPS, which falls below the 60 FPS threshold most players prefer. High is only marginally better at 40.7 FPS, making both presets suboptimal for 4K. The Medium preset, however, provides 57.7 FPS — a 31% improvement over Ultra and a 42% improvement over High. While not a locked 60 FPS, Medium at 4K offers the best balance between visual fidelity and playability. Low at 4K yields 73.2 FPS, but the graphical compromises are severe for a stealth game that relies on lighting and shadow detail.

The data suggests a simple rule: use Ultra for 1080p and 1440p, switch to Medium for 4K. The Low preset at any resolution (172.4 FPS at 1080p, 128.2 FPS at 1440p, 73.2 FPS at 4K) is only necessary for extreme refresh rate displays or if the user prioritizes absolute frame rate over visual quality.

GPU Role

The NVIDIA GeForce RTX 4060, with its 8 GB of GDDR6 memory on a 128-bit bus and 272.0 GB/s bandwidth, plays the dominant role in determining Thief's performance ceiling at higher resolutions. The GPU's boost clock of 2460 MHz and base clock of 1830 MHz, combined with 3072 shading units, drive the rendering pipeline. The data shows that the GPU becomes the limiting factor as resolution increases: from 1080p Medium (142.3 FPS) to 1440p Medium (95.3 FPS), there is a 33% performance drop, and from 1440p Medium to 4K Medium (57.7 FPS), another 39% drop. This scaling pattern is characteristic of a GPU-bound scenario at higher resolutions.

The 8 GB VRAM capacity is sufficient for Thief's 2014-era textures, as evidenced by the fact that the game runs without apparent memory-related stutters even at 4K Ultra (44.2 FPS). However, the 128-bit memory bus and 272.0 GB/s bandwidth are modest by modern standards, which explains why the RTX 4060's performance in this title trails its nearest rivals. The GPU's average benchmark score of 23181 places it at the 66th percentile of all GPUs, with the AMD Radeon RX 6600M scoring 0.6% higher and the Intel Arc B580 scoring 0.7% lower. This close grouping indicates that the RTX 4060 is competitive but not class-leading in raw throughput.

How This Combo Ranks

This specific combination of Intel Core i5-12400 and NVIDIA GeForce RTX 4060 ranks 859th out of 1642 tested combos in Thief, placing it in the 48th percentile of all system configurations. This mid-pack ranking is somewhat surprising given the individual components' performance, but it reflects the fact that Thief is a 2014 title that many higher-end modern GPUs can max out with ease. The i5-12400 itself ranks at the 77th percentile among all CPUs, with an average benchmark score of 19850, while the RTX 4060 sits at the 66th percentile among GPUs with a score of 23181.

The combo's rank suggests that while this system delivers solid playable performance, it does not push the upper echelons of Thief's leaderboard. The CPU's nearest rivals — the Intel Core i7-9700 (0.1% higher score), Intel Core i7-8700 (0.2% lower), and Intel Core i5-11600K (0.4% higher) — all produce nearly identical CPU-bound results. Similarly, the GPU's nearest rivals are within 0.8% of its average score. This indicates that the combo's rank is primarily determined by the GPU's mid-tier standing rather than any CPU limitation.

CPU Role

The Intel Core i5-12400 brings 6 cores and 12 threads with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its Alder Lake architecture and 18 MB of shared L3 cache provide ample processing power for Thief's AI-driven stealth mechanics and physics calculations. The CPU's benchmark results show strong multi-threaded performance: a Cinebench R23 multi-core score of 15935 and a Passmark multithread score of 18747. Single-thread performance is equally robust, with a Cinebench R23 single-core score of 2249 and a Passmark single-thread score of 3456.

In Thief, the CPU's role is largely secondary to the GPU, but it ensures that frame rates remain stable even in complex scenes with multiple AI enemies and dynamic lighting. The data supports this assessment: at 1080p Low, the system reaches 172.4 FPS, which is well beyond what most displays can show, indicating that the CPU is not creating a bottleneck. The i5-12400's 65W TDP and dual-channel DDR4/DDR5 memory support further contribute to consistent performance, though the game itself does not stress the CPU to its limits.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across twelve configurations. At 1920x1080, the results are: Low 172.4 FPS, Medium 142.3 FPS, High 108 FPS, and Ultra 104.9 FPS. The progression from Low to Ultra shows a 39% reduction in frame rate, with the largest single drop occurring between Medium and High (24% decrease). At 2560x1440, the numbers are: Low 128.2 FPS, Medium 95.3 FPS, High 72.4 FPS, and Ultra 72.9 FPS. Notably, High and Ultra are nearly identical at this resolution, differing by only 0.7%.

At 3840x2160, the performance falls significantly: Low 73.2 FPS, Medium 57.7 FPS, High 40.7 FPS, and Ultra 44.2 FPS. Interestingly, Ultra outperforms High at 4K by 8.6%, which is an anomaly likely related to specific rendering paths in the game engine. Across all resolutions, Low settings always exceed 70 FPS, ensuring that even the most demanding 4K displays can achieve smooth playback with reduced visual fidelity.

Resolution Scaling

The resolution scaling behavior reveals a classic GPU-bound pattern. Moving from 1080p to 1440p at Medium settings reduces average FPS from 142.3 to 95.3, a 33% drop. Continuing to 4K Medium brings another 39% reduction to 57.7 FPS. This compounding effect — a total 59% decrease from 1080p to 4K — demonstrates that the RTX 4060's rendering throughput is the limiting factor at higher pixel counts.

At Ultra settings, the scaling is even more pronounced: 104.9 FPS at 1080p drops to 72.9 FPS at 1440p (31% reduction) and then to 44.2 FPS at 4K (57% reduction from 1440p, 58% from 1080p). The 4K Ultra result of 44.2 FPS is barely playable, confirming that this setting is not recommended for 4K. The Low preset shows the least severe scaling: 172.4 FPS at 1080p, 128.2 FPS at 1440p (26% drop), and 73.2 FPS at 4K (43% drop from 1440p). This suggests that as the GPU load decreases (via lower settings), the CPU begins to play a more significant role, mitigating the resolution penalty.

The data clearly indicates that the RTX 4060 is the primary bottleneck at 4K, while at 1080p, the system has sufficient headroom that even Ultra settings leave performance headroom for background tasks or streaming. For users targeting 4K, the Medium preset is the practical ceiling; for those with 1080p or 1440p displays, Ultra provides the best experience without meaningful compromise.
