Thief

The Intel Core i5-12400 and AMD Radeon RX 7600 XT combination delivers a fascinating performance profile in Thief, a 2014 stealth title that remains demanding at higher resolutions. The measured data reveals a system that is clearly capable of high refresh rates at 1080p but begins to show its limitations as the pixel count climbs. The benchmark results indicate a classic tension between a strong mid-range CPU and a GPU that, while equipped with a large memory buffer, struggles to maintain fluid frame rates at 4K with maximum settings. This analysis will break down how this pairing scales across resolutions, where it ranks among other tested configurations, and what the data implies about the limiting components in this specific game.

Resolution Scaling

The FPS drop from 1080p to 4K is telling. At 1920x1080 with Low settings, the combo produces a very high average of 158.3 FPS. Moving to 2560x1440, that figure falls to 108.6 FPS, and at 3840x2160, it drops to 62.8 FPS. This represents a 60% reduction in frame rate from 1080p to 4K at the lowest quality preset, which suggests the GPU is becoming a significant bottleneck at higher resolutions, even when the graphical load is light.

The scaling pattern is even more pronounced at higher settings. With Ultra settings, the average FPS at 1080p is 88.0, which drops to 58.8 at 1440p and plummets to 34.4 at 4K. The gap between Low and Ultra at 4K is substantial (62.8 FPS vs 34.4 FPS), indicating that the Radeon RX 7600 XT's raw processing power is the primary constraint. At 1080p, the CPU can feed the GPU enough data to maintain high frame rates, but as the resolution increases, the GPU's workload expands exponentially, and its compute units become the limiting factor. The data shows that this is not a CPU-limited scenario at higher resolutions; it is firmly a GPU-bound one.

How This Combo Ranks

In the database of tested combinations for Thief, this specific pairing holds a rank of 1082 out of 1642 combos. This places it in the lower-mid tier of all tested systems, which is a surprising result given the hardware's individual specifications. The percentile ranking suggests that while this is not a weak setup, a significant number of other configurations deliver higher average frame rates in this specific title.

This ranking implies that the combination of the i5-12400 and RX 7600 XT is not optimal for maximising Thief's performance ceiling. The data suggests that other pairings, likely with more powerful GPUs, are able to achieve much higher scores. The rank is a holistic measure, likely incorporating performance across all tested resolutions and settings. Given that the GPU's nearest rivals in general benchmarks include the RTX 2060 SUPER and the RX 7600, its mid-pack standing in this game's specific benchmark is a data point that suggests Thief's engine may not be fully leveraging the strengths of this modern RDNA 3 architecture.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor based on the Alder Lake architecture. It has a base clock of 2.50 GHz and a boost clock of 4.40 GHz. In synthetic benchmarks, it scores 15,935 in Cinebench R23 multicore and 2,249 in single-core tests. This level of single-thread performance is crucial for older games like Thief, which often rely heavily on one or two cores.

The benchmark results suggest the CPU is more than adequate for this game at most settings. At 1080p Low, the 158.3 FPS average indicates the CPU is capable of driving a high frame rate. However, the fact that the FPS does not scale linearly with resolution at Low settings (108.6 FPS at 1440p and 62.8 FPS at 4K) points to the GPU becoming the main constraint. The CPU's 18 MB of shared L3 cache and 12 threads provide ample headroom for the game's logic and physics, meaning that as long as the GPU can keep up, the i5-12400 is unlikely to be the cause of frame drops. Its 77th percentile ranking against all CPUs reinforces that it is a competent performer, sitting just 0.1% ahead of the Intel Core i7-9700 and 0.4% ahead of the Core i5-11600K in average benchmark scores.

Measured FPS Breakdown

The measured data provides a complete picture of performance across three resolutions and four quality presets. At 1920x1080, the combo delivers excellent results: 158.3 FPS on Low, 123.5 FPS on Medium, 92.1 FPS on High, and 88.0 FPS on Ultra. These numbers clearly show that for 1080p gaming, this system is more than capable of providing a very smooth experience, even with the highest settings.

At 2560x1440, performance remains very playable. The average FPS is 108.6 on Low, 86.2 on Medium, 67.1 on High, and 58.8 on Ultra. The drop from High to Ultra at this resolution is notable (67.1 to 58.8 FPS), suggesting that the Ultra preset includes effects that are particularly taxing on the GPU. Moving to 3840x2160, the system begins to struggle. The average FPS is 62.8 on Low, 49.5 on Medium, 36.3 on High, and 34.4 on Ultra. None of the 4K results reach the 60 FPS threshold, and the Ultra preset is effectively unplayable for a smooth experience. The data shows a consistent and predictable degradation in performance as resolution and settings increase.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with a Navi 33 chip. It features 16 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 288.0 GB/s. Its boost clock is rated at 2755 MHz and its game clock at 2470 MHz. In synthetic benchmarks, it achieves a Passmark G3D score of 17,132, placing it in the 63rd percentile of all GPUs.

The GPU's role in Thief is clearly the dominant factor in determining overall performance. The 4K results, where even Low settings only yield 62.8 FPS, highlight a raw compute limit. The 16 GB VRAM buffer is not a limiting factor in this game, as even at 4K Ultra, the memory capacity is likely sufficient. Instead, the bottleneck is the GPU's shading power and fill rate. The data shows that the RX 7600 XT is positioned between the RX 7600 (which has a 0.6% higher average benchmark score) and the RX 460 (which has a 0.3% lower score). This indicates that while it is a solid performer, it does not have the headroom to tackle 4K Ultra settings in this title. The 22.57 TFLOPS of FP32 performance is simply not enough to maintain high frame rates at that resolution with maximum visual fidelity.

Settings Recommendations

Based on the measured data, the optimal experience depends heavily on the target resolution. For 1080p gaming, the Ultra preset is the clear choice, delivering an average of 88.0 FPS and providing the best visual quality without sacrificing smoothness. The High preset is also excellent at 92.1 FPS, but the minimal performance cost of Ultra makes it the better option for users with 1080p monitors.

For 2560x1440, the High preset is the sweet spot. It provides a solid 67.1 FPS average, which is above the 60 FPS threshold for smooth gameplay. The Ultra preset at 58.8 FPS is a viable option for those who prefer maximum visual fidelity over a guaranteed 60 FPS, but it comes with a noticeable performance hit. The Medium preset offers a very high 86.2 FPS, but the visual compromise is likely not worth it when High is so close in performance.

At 3840x2160, the data suggests that this combination is not suited for 4K gaming. The Low preset is the only one that approaches playability at 62.8 FPS, but the visual quality will be severely compromised. The Medium preset at 49.5 FPS and High at 36.3 FPS are too low for a satisfying experience. For 4K users, it is advisable to either lower the resolution to 1440p or significantly reduce the in-game settings to Low, accepting the graphical trade-offs.
