Thief

The AMD Ryzen 5 5600F and AMD Radeon RX 6600 XT pairing delivers a playable but resolution-sensitive experience in Thief, with the data showing a clear shift from CPU-bound behavior at 1080p to GPU-bound behavior at 4K. This combination ranks 2093 out of 2851 tested combos in this game, placing it in the lower-middle portion of the database, and the measured frame rates across three resolutions and four quality presets reveal where this system excels and where it struggles.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and tells a clear story about which component becomes the limiting factor. At High settings, the average FPS falls from 90 at 1920x1080 to 62 at 2560x1440, then to 36 at 3840x2160. That is a 31% reduction from 1080p to 1440p, and another 42% reduction from 1440p to 4K. The scaling is not linear, and the steep decline at 4K indicates the RX 6600 XT is being pushed hard by the pixel count.

Looking at Low settings, the pattern is similar but with higher absolute numbers. At 1920x1080, the combo hits 138 FPS, dropping to 107 at 2560x1440, and then to 63 at 3840x2160. The 1440p to 4K drop here is 41%, nearly identical to the High preset drop. This consistency across presets suggests that at 4K, the GPU's raw throughput—not the settings level—is the primary constraint. Even at Low, the card cannot maintain 60 FPS at 4K, which is a strong indicator that the Radeon RX 6600 XT lacks the fill rate and memory bandwidth for ultra-high-resolution gaming in this title.

The Medium preset provides the only complete data with min and max FPS recorded. At 1920x1080, the average is 118 FPS with a minimum of 100 and maximum of 136. At 2560x1440, the average drops to 81 FPS with a range of 69 to 93. At 3840x2160, the average falls to 48 FPS with a range of 40 to 55. The minimum FPS at 4K Medium is 40, which means there are moments where the experience dips below 30 FPS territory, though the average stays playable. The gap between min and max FPS widens at higher resolutions, going from a 36 FPS spread at 1080p to a 15 FPS spread at 4K—wait, that is incorrect. The spread is 36 FPS at 1080p (100 to 136), 24 FPS at 1440p (69 to 93), and 15 FPS at 4K (40 to 55). So the variance actually shrinks as resolution increases, which is typical of GPU-bound scenarios where frame pacing becomes more consistent under heavy load.

The Ultra preset shows the lowest overall performance, with 85 FPS at 1080p, 59 FPS at 1440p, and 34 FPS at 4K. The 1080p to 1440p drop is 31%, and the 1440p to 4K drop is 42%. These percentages match the High preset almost exactly, reinforcing that the scaling behavior is resolution-driven rather than settings-driven. The data suggests that this combo is best suited for 1080p and 1440p gaming, with 4K being playable only at Low settings (63 FPS average) or Medium settings (48 FPS average) but not at High or Ultra.

CPU Role

The AMD Ryzen 5 5600F is a 6-core, 12-thread processor from the 5000 series, built on the Zen 3 architecture with a 7 nm process. Its base clock is 3.00 GHz and boost clock is 4.00 GHz, with a TDP of 65 W. The CPU has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of shared L3 cache. It supports DDR4 memory with dual-channel configuration and a bandwidth of 51.2 GB/s, and it connects via PCIe Gen 4 with 20 lanes.

In Thief, the CPU's role becomes more apparent at lower resolutions where the GPU is less burdened. At 1080p Low, the combo reaches 138 FPS, which is a high frame rate that requires solid single-thread performance. The Ryzen 5 5600F's PassMark single-thread score is 2872, and its multithread score is 19236. The CPU's percentile versus all CPUs is 85, meaning it outperforms 85% of tested processors in general benchmark terms.

The nearest rivals for the Ryzen 5 5600F are interesting in this context. The Intel Core Ultra 5 225 has an average benchmark score of 36938, which is essentially identical to the Ryzen 5 5600F's 36945, with a delta of 0%. The AMD Ryzen 5 5500X3D scores 37018, which is 0.2% higher. The AMD Ryzen AI 7 PRO 450 scores 37093, 0.4% higher, and the Intel Core i9-12900T scores 37112, 0.5% higher. These are all within a half percent of each other, indicating that the Ryzen 5 5600F is right at the midpoint of its performance class. In Thief, this level of CPU performance is sufficient to feed the GPU at 1080p, as evidenced by the 138 FPS Low result. However, at 1440p and 4K, the frame rates drop in a way that suggests the GPU becomes the bottleneck, not the CPU.

The 6-core, 12-thread configuration is adequate for a 2014 stealth game like Thief, which was released on 2014-02-24 and likely does not scale beyond a few threads. The CPU's 32 MB of L3 cache is generous and helps with game data locality, but the measured FPS data does not show any CPU-related stutter or inconsistency at any resolution. The min FPS values at Medium settings (100 at 1080p, 69 at 1440p, 40 at 4K) are all reasonably close to their averages, suggesting that the CPU is not causing frame time spikes. The Ryzen 5 5600F's PassMark physics score of 1043 is modest, but Thief's physics load appears manageable given the consistent frame rates.

GPU Role

The AMD Radeon RX 6600 XT is a RDNA 2.0 architecture GPU with the Navi 23 chip, built on a 7 nm process at TSMC. It has 2048 shading units, 128 texture mapping units, and 64 raster output units, along with 32 ray tracing cores. The GPU's base clock is 1968 MHz, its game clock is 2359 MHz, and its boost clock is 2589 MHz. The memory configuration consists of 8 GB of GDDR6 on a 128-bit bus, with a bandwidth of 256.0 GB/s. The memory clock is 2000 MHz or 16 Gbps effective. The GPU has a TDP of 160 W and requires a 450 W suggested PSU. Its pixel rate is 165.7 GPixel/s, texture rate is 331.4 GTexel/s, and FP32 performance is 10.60 TFLOPS.

In Thief, the RX 6600 XT's 8 GB of VRAM is not a limiting factor at any resolution, as the game is from 2014 and does not have massive texture requirements. The GPU's 128-bit memory bus and 256.0 GB/s bandwidth are sufficient for this title's demands. The GPU's PassMark G3D score is 16461, and its percentile versus all GPUs is 70, meaning it outperforms 70% of tested graphics cards.

The nearest rivals for the RX 6600 XT are notable. The NVIDIA GeForce GTX 1630 has an average score of 24277, which is 0.7% lower than the RX 6600 XT's 24442. The Intel Arc A350M scores 24647, which is 0.8% higher. The NVIDIA GeForce GTX 780 Ti scores 24236, 0.8% lower, and the NVIDIA GeForce RTX 2080 SUPER scores 24170, 1.1% lower. This is a strange grouping because the RTX 2080 SUPER is a much more powerful card in real-world gaming, but the benchmark averages place it slightly below the RX 6600 XT. Regardless, the RX 6600 XT's performance in Thief is what matters here.

At 1080p, the GPU is clearly capable of high frame rates, with 138 FPS at Low and 90 FPS at High. At 1440p, it delivers 107 FPS at Low and 62 FPS at High, which is still playable. At 4K, the GPU struggles, with 63 FPS at Low being the only preset that exceeds 60 FPS. The 4K Ultra result of 34 FPS is the worst-case scenario, and even 4K High at 36 FPS is not smooth. The GPU's 10.60 TFLOPS of FP32 performance is simply not enough to maintain high frame rates at 4K in this game, especially with the demanding Ultra settings. The texture rate of 331.4 GTexel/s and pixel rate of 165.7 GPixel/s are the theoretical limits, and the measured data shows the card approaching those limits at 4K.

Measured FPS Breakdown

At 1920x1080, the combo delivers strong performance across all settings. Low settings produce an average of 138 FPS, Medium produces 118 FPS with a range of 100 to 136, High produces 90 FPS, and Ultra produces 85 FPS. The gap between High and Ultra is only 5 FPS, which suggests that the Ultra preset adds visual features that do not heavily tax the GPU at this resolution. The 1080p results are all above 60 FPS, making this resolution ideal for the combo.

At 2560x1440, the performance drops noticeably but remains playable. Low settings average 107 FPS, Medium averages 81 FPS with a range of 69 to 93, High averages 62 FPS, and Ultra averages 59 FPS. The High and Ultra results are very close, with only 3 FPS separating them. The 1440p Medium result of 81 FPS is solid, but the High and Ultra presets dip below 60 FPS, which may be noticeable on a 60 Hz monitor. The minimum FPS at 1440p Medium is 69, which is still above 60, indicating good frame pacing.

At 3840x2160, the combo falls below 60 FPS for most settings. Low settings average 63 FPS, which is just above the 60 FPS threshold. Medium averages 48 FPS with a range of 40 to 55, High averages 36 FPS, and Ultra averages 34 FPS. The 4K results show that this combination is not suited for 4K gaming at high quality. Even at Low, the average of 63 FPS is marginal, and any heavy scene could push it below 60. The Medium preset's minimum of 40 FPS indicates that there are moments of significant slowdown. The 4K Ultra result of 34 FPS is barely playable and would likely be frustrating for most users.

The data across all resolutions shows a consistent pattern: the combo excels at 1080p, handles 1440p reasonably well, and struggles at 4K. The settings scaling is also consistent, with Low to Medium providing the biggest FPS gains, while High to Ultra provides diminishing returns. For example, at 1080p, going from Low to Medium costs 20 FPS (138 to 118), Medium to High costs 28 FPS (118 to 90), and High to Ultra costs only 5 FPS (90 to 85). This suggests that the Ultra preset is not well optimized or that the visual improvements are minimal compared to the performance cost.

How This Combo Ranks

The combo ranks 2093 out of 2851 tested combos in Thief, placing it at approximately the 73rd percentile of all combinations. This means that about 73% of tested combos perform better than this pairing in this specific game. The rank is heavily influenced by the GPU's limitations at higher resolutions, as the CPU is relatively strong with an 85th percentile score.

The ranking context becomes clearer when considering the individual components. The Ryzen 5 5600F is in the top 15% of CPUs, while the RX 6600 XT is in the top 30% of GPUs. The combo's rank of 2093 out of 2851 suggests that Thief is a game where the GPU is more important than the CPU, and the RX 6600 XT's mid-range positioning drags the overall rank down. A combination with a stronger GPU would likely rank higher, even with a weaker CPU, because Thief's performance scales more with GPU than CPU.

The rank also indicates that this combo is not a top-tier choice for Thief, but it is not a poor one either. It is firmly in the middle of the database, which means it can play the game at acceptable frame rates at 1080p and 1440p, but it will not provide a high-refresh-rate experience at 4K. The data suggests that users with this combo should stick to 1080p or 1440p and adjust settings to match their preferred frame rate target.
