Thief

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6600 lands at rank 2892 out of 3720 tested combos in Thief. That places this configuration in the lower-middle portion of the overall database, meaning it will handle the game but without the headroom found in higher-tier pairings. The percentile standing of the individual components reinforces this: the CPU sits at the 74th percentile against all processors, while the GPU is at the 63rd percentile against all graphics cards. In practical terms, this combo is not a top-tier performer for Thief, but it is far from the bottom of the barrel. The data shows a system that can deliver playable frame rates at most settings, provided the resolution is kept in check.

The ranking becomes more meaningful when you consider that the CPU's average benchmark score of 21088 is nearly identical to that of its nearest rivals. The Intel Core i3-1220P scores 21066, a delta of just 0.1%, and the Intel Core Ultra 7 256V scores 21112, a delta of -0.1%. This tells you the processor is not a bottleneck in any unique way; it performs exactly where its specifications suggest it should. The GPU tells a similar story with an average benchmark score of 19036, sitting within 0.4% of the NVIDIA RTX 2000 Ada Generation and within 0.1% of the NVIDIA GeForce RTX 4050 Mobile. Neither component is an outlier, so the measured FPS in Thief is a direct reflection of their combined mid-range capability.

GPU Role

The Radeon RX 6600 is the primary driver of visual output in this pairing, and its specifications explain a lot about the measured results. It comes with 8 GB of GDDR6 memory on a 128-bit bus, delivering 224.0 GB/s of bandwidth. For a game released in 2014, that memory configuration is more than sufficient for texture loading and asset streaming at 1080p and 1440p. The GPU's clock behavior is also relevant: the base clock is 1626 MHz, but the boost clock reaches 2491 MHz, with a game clock of 2044 MHz. The difference between base and boost is substantial, and in a title like Thief that does not stress the GPU to its absolute limits, the card will likely spend most of its time near the boost ceiling.

The architecture is RDNA 2.0 on a 7 nm process from TSMC, with 1792 shading units and 64 ROPs. The pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s are modest figures by modern standards, but they are adequate for a stealth game that relies on interior environments and controlled lighting rather than sprawling open-world vistas. The GPU's FP32 performance of 8.928 TFLOPS gives it enough compute headroom for the DirectX 11-era rendering path that Thief uses. It is also worth remembering the card supports DirectX 12 Ultimate, so it is not lacking in API compatibility, but the game itself will not take advantage of that. In this specific benchmark, the GPU is not the limiting factor at lower resolutions, but its role becomes more pronounced as resolution increases and the pixel fill rate starts to matter more.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases from 1080p to 4K. At 1080p with Low settings, the combo produces 142 FPS. Moving to 1440p at Low drops that to 98 FPS, a reduction of roughly 31%. At 4K Low, the frame rate falls to 57 FPS, which is about 42% lower than the 1440p figure and 60% lower than the 1080p result. This steep drop-off indicates that the GPU is being pushed harder as pixel count rises, but the CPU is still keeping up. The story changes when you look at the highest settings. At Ultra, the frame rates are 78 FPS at 1080p, 54 FPS at 1440p, and 32 FPS at 4K. The gap between 1080p and 1440p at Ultra is about 31%, and the gap between 1440p and 4K is about 41%.

These percentages tell you that the scaling is relatively consistent across settings, which points to a GPU-bound scenario at higher resolutions. At 1080p Low, the frame rate of 142 FPS suggests the CPU is still capable of feeding the GPU without bottlenecking, but the 4K Low result of 57 FPS indicates the GPU is now the primary constraint. The limiting component shifts depending on resolution. At 1080p, the combination is balanced, with the CPU able to push enough frames to keep the GPU busy. At 4K, the RX 6600's 8 GB of VRAM and 128-bit bus become the ceiling, and the CPU's performance becomes almost irrelevant. The data shows that if you want to play at 4K, you will be firmly GPU-limited, while at 1080p, the system is more evenly matched.

Settings Recommendations

Looking at the measured rows, the best experience per the data is at 1080p with Medium settings. The average FPS there is 108, with a minimum of 92 and a maximum of 124. That gives you a comfortable margin above the 60 FPS threshold, and the min frame rate of 92 ensures that even in demanding scenes, you will not drop into stutter territory. High settings at 1080p still deliver a solid 82 FPS average, but the lack of min/max data makes it harder to judge consistency. Ultra at 1080p drops to 78 FPS, which is still playable, but you are giving up headroom for visual gains that may not be noticeable in a game like Thief, where the art style is already dark and atmospheric.

At 1440p, Medium settings produce a 74 FPS average with a min of 63 and a max of 85. That is borderline acceptable for a smooth experience, but the min of 63 means you will occasionally dip near 60 FPS. If you have a 144 Hz monitor, you will want to stick to 1080p. If you are on a 60 Hz display, 1440p Medium is the sweet spot. The data does not support 4K as a viable option for this combo. Even at Low settings, 4K only reaches 57 FPS, and at Medium it drops to 44 FPS with a min of 37. That is not a smooth experience. The recommendation is clear: prioritize 1080p Medium or High for the best balance of visual quality and frame rate, or 1440p Medium if you can tolerate occasional dips near 60 FPS.

Measured FPS Breakdown

The measured data covers three resolutions and four settings levels, providing a complete picture of performance. At 1920x1080, the frame rates are as follows: Low averages 142 FPS, Medium averages 108 FPS with a range of 92 to 124, High averages 82 FPS, and Ultra averages 78 FPS. The jump from Low to Medium is a 24% reduction, while the jump from Medium to High is another 24% reduction. The difference between High and Ultra is only 4 FPS, which suggests that Ultra is not offering significant visual improvements over High for the performance cost.

At 2560x1440, the results are: Low averages 98 FPS, Medium averages 74 FPS with a range of 63 to 85, High averages 56 FPS, and Ultra averages 54 FPS. The scaling from Low to Medium is a 24% drop, and from Medium to High it is another 24% drop. The High to Ultra transition is again minimal, with only a 2 FPS difference. This pattern repeats at 3840x2160: Low averages 57 FPS, Medium averages 44 FPS with a range of 37 to 50, High averages 33 FPS, and Ultra averages 32 FPS. The drop from Low to Medium is 23%, and from Medium to High it is 25%. The High to Ultra gap is just 1 FPS.

The consistency of these percentage drops across resolutions is notable. It indicates that the game's settings have a uniform impact on performance regardless of pixel count. The only exception is the High to Ultra transition, which consistently yields less than 5% improvement in frame rate, suggesting that Ultra is largely a placebo setting in this game for this hardware. The data shows that Low settings are the only option for a playable 4K experience, and even then, 57 FPS is marginal. For 1440p, Medium is the highest you can go while staying above 60 FPS on average. For 1080p, you have the freedom to choose any setting, with Ultra still delivering 78 FPS.

FAQ

Q: Can this combo run Thief at 4K smoothly?

A: No. The data shows that at 4K, even Low settings only produce 57 FPS on average. Medium drops to 44 FPS with a minimum of 37 FPS, and High and Ultra fall to 33 and 32 FPS respectively. This is not a smooth experience for a game that benefits from consistent frame pacing.

Q: What is the best resolution for a 60 Hz monitor?

A: 1440p with Medium settings is the best option for a 60 Hz display. The average FPS is 74, with a minimum of 63, so you will stay above the refresh rate most of the time. If you want more headroom, 1080p High delivers 82 FPS on average.

Q: Is the CPU or GPU the bottleneck in this game?

A: It depends on the resolution. At 1080p Low, the combo reaches 142 FPS, indicating the CPU is capable of driving high frame rates. At 4K Low, the frame rate drops to 57 FPS, showing the GPU is the limiting factor at higher resolutions. The bottleneck shifts from balanced at 1080p to GPU-bound at 4K.

Q: How does the RX 6600 compare to its nearest rival in this context?

A: The RX 6600 has an average benchmark score of 19036, which is within 0.1% of the NVIDIA GeForce RTX 4050 Mobile and exactly 0% from the NVIDIA Quadro K6000. The performance delta is negligible, so you should not expect significant differences in Thief based on these comparison points.

Q: Is the Ryzen 5 5600G holding back the RX 6600 in Thief?

A: The data does not suggest the CPU is a significant bottleneck. The Ryzen 5 5600G has an average benchmark score of 21088, which is within 0.1% of the Intel Core i3-1220P. At 1080p Low, the combo produces 142 FPS, which indicates the processor can feed the GPU effectively at mainstream resolutions.
