Thief

The AMD Radeon RX 7600 XT paired with the Intel Core i5-9400 delivers a highly playable experience in Thief across most settings, with the data indicating that 1080p remains the resolution where this combination truly shines. At 1440p, the combo still produces strong frame rates, but the step to 4K exposes the GPU's limitations under higher graphical loads. The measured results show a clear hierarchy: Low settings push frame rates well past 100 FPS at 1080p, while Ultra settings at 4K drop below the 40 FPS threshold, making the choice of preset and resolution critical for a smooth experience.

Settings Recommendations

The benchmark data for Thief reveals that the High preset at 2560x1440 offers the most balanced experience for this hardware combination, producing an average of 63.4 FPS. This is a significant jump from the 4K High result of 36.3 FPS, which falls below a comfortable playability threshold. At 1080p, the High preset yields 96.8 FPS, which is excellent, but the move to 1440p retains the visual fidelity while still maintaining a frame rate that is well above 60 FPS. For users prioritizing a locked 60 FPS experience at 4K, the data shows that only the Low preset at 3840x2160 achieves this, with an average of 66.1 FPS.

The Medium preset at 1440p provides 86.3 FPS, which is noticeably higher than High, but the difference in visual quality is often less impactful than the performance gain. However, the High preset at 1440p represents a more substantial visual upgrade over Medium while still delivering a smooth 63.4 FPS. At 1080p, the Ultra preset is the best choice for maximizing image quality, as it still achieves a very respectable 86.5 FPS, only slightly behind the High preset's 96.8 FPS. Given that the Ultra preset at 1440p drops to 60.2 FPS, the data suggests that 1080p Ultra is the sweet spot for those who want the highest settings without compromising on fluidity. The Low preset at 1080p, with its 118 FPS average, is the only option that approaches high-refresh-rate territory, but it sacrifices too much visual fidelity for most users.

How This Combo Ranks

In the database of tested hardware combinations for Thief, this pairing of the Intel Core i5-9400 and AMD Radeon RX 7600 XT holds a rank of 1262 out of 1642 tested combos. This places it in the lower-middle portion of the rankings, suggesting that while the combo is certainly capable, there are many other configurations that deliver higher frame rates in this specific title. The ranking indicates that the CPU is a potential bottleneck in this pairing, as its benchmark scores are modest compared to the GPU's capabilities. The Intel Core i5-9400 has a 50th percentile ranking among all CPUs, while the RX 7600 XT sits at the 63rd percentile among all GPUs, showing a slight mismatch where the GPU is relatively stronger.

When examining the CPU's nearest rivals, the data shows the Core i5-9400 is extremely close in average benchmark score to the Intel Core i3-10305, with a 0.2% difference, and the Intel Core i3-1125G4, also a 0.2% difference. It is also 0.4% ahead of the Intel Xeon E-2134. This suggests there is no significant performance separation between these processors in general compute tasks. For the GPU, the RX 7600 XT is only 0.3% ahead of the AMD Radeon RX 460 in average benchmark score, and 0.6% behind the AMD Radeon RX 7600. This tight grouping indicates the RX 7600 XT's performance is well-understood and that its position in the Thief rankings is likely influenced by the CPU's limitations.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with a Navi 33 chip, manufactured on a 6 nm process. It features 16 GB of GDDR6 memory on a 128-bit bus, delivering a memory bandwidth of 288.0 GB/s. The GPU's core clocks are substantial, with a boost clock of 2755 MHz and a game clock of 2470 MHz. These specifications contribute to a strong fill rate, with a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s. The GPU also supports DirectX 12 Ultimate, ensuring compatibility with modern rendering features.

In the context of Thief, the GPU's role becomes increasingly dominant as resolution increases. The data shows a clear trend: the frame rate at 1080p Low is 118 FPS, but at 4K Low it drops to 66.1 FPS, a reduction of approximately 44%. This indicates that even at Low settings, the sheer number of pixels at 4K places a heavy load on the GPU. The 16 GB VRAM buffer is more than sufficient for this 2014 title, so memory capacity is not a limiting factor. Instead, the GPU's raw compute power, represented by its 22.57 TFLOPS of FP32 performance, is what drives the frame rates. The high boost clock of 2755 MHz helps maintain performance, but the data confirms that the RX 7600 XT is best suited for 1080p and 1440p gaming in this title, rather than 4K.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are consistently high across all presets. The Low preset achieves 118 FPS, the Medium preset reaches 107.9 FPS, the High preset records 96.8 FPS, and the Ultra preset delivers 86.5 FPS. The variation from Low to Ultra is about 31 FPS, showing that the GPU has ample headroom to handle the increased graphical load at this resolution. The gap between Medium and High is 11.1 FPS, while the gap between High and Ultra is 10.3 FPS, indicating a smooth scaling curve.

Moving to 2560x1440, the frame rates remain playable but show a more pronounced impact from the settings. The Low preset produces 106.3 FPS, which is a modest 11.7 FPS drop from the 1080p result. The Medium preset delivers 86.3 FPS, the High preset manages 63.4 FPS, and the Ultra preset falls to 60.2 FPS. The most significant drop occurs between Medium and High, where the frame rate decreases by 22.9 FPS, suggesting that the High preset introduces a substantial increase in GPU workload. At this resolution, the Ultra preset barely maintains a 60 FPS average, making High the more sensible choice for a consistent experience.

At 3840x2160, the GPU's limitations become evident. The Low preset is the only one that remains comfortably playable, with an average of 66.1 FPS. The Medium preset drops to 49.9 FPS, while both the High and Ultra presets fall below 40 FPS, with averages of 36.3 FPS and 36.1 FPS, respectively. The difference between High and Ultra at 4K is negligible, at just 0.2 FPS, indicating that the Ultra preset offers no performance penalty but also no meaningful gain over High in this title. The data strongly suggests avoiding High or Ultra settings at 4K with this combo.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a clear picture of the system's bottleneck. At the Low preset, the average frame rate drops from 118 FPS at 1080p to 106.3 FPS at 1440p, a decrease of 9.9%. From 1440p to 4K, it drops further to 66.1 FPS, a much steeper 37.8% decrease. This pattern indicates that at Low settings, the CPU is able to feed the GPU adequately at 1080p and 1440p, but the GPU becomes the limiting factor at 4K due to the massive increase in pixel count.

At the High preset, the scaling is even more dramatic. The frame rate falls from 96.8 FPS at 1080p to 63.4 FPS at 1440p, a 34.5% drop, and then to 36.3 FPS at 4K, a 42.7% drop from 1440p. This steep decline highlights that the GPU is the primary constraint at higher resolutions and settings. The Ultra preset shows a similar trend, with a 30.4% drop from 1080p to 1440p (from 86.5 to 60.2 FPS) and a 40% drop from 1440p to 4K (from 60.2 to 36.1 FPS). The data indicates that the Intel Core i5-9400 provides sufficient performance for this game at 1080p, but the RX 7600 XT's pixel throughput is the deciding factor as resolution scales, particularly beyond 1440p.

FAQ

*Q: What is the best resolution for this combo in Thief?*

A: The data shows that 1080p is the most consistent resolution, with all presets delivering above 86 FPS. At 1440p, High and Ultra presets hover near 60 FPS, while 4K only offers playable frame rates on the Low preset.
