Thief

The AMD Ryzen 5 2600 and Radeon RX 6600 pairing in Thief shows a system that is clearly rendering-bound at higher resolutions, with the CPU proving sufficient for the game's 2014-era engine demands. The recorded data indicates that the graphics card is the primary limiting factor when moving beyond 1080p, while the processor's six cores and twelve threads provide ample headroom for the stealth title's workload.

Resolution Scaling

The measured FPS data shows a consistent and predictable drop as resolution increases from 1920x1080 to 3840x2160. At Medium settings, the average frame rate falls from 99 FPS at 1080p to 74 FPS at 1440p, then to 44 FPS at 4K. This represents a 25% reduction moving from 1080p to 1440p, followed by a 41% reduction moving from 1440p to 4K. The scaling pattern indicates that pixel throughput becomes the dominant constraint at higher resolutions, which is typical for a GPU with an 8 GB memory buffer and a 128-bit bus.

At High settings, the same trend appears: 82 FPS at 1080p, 56 FPS at 1440p, and 33 FPS at 4K. The percentage drops are steeper here, with a 32% loss from 1080p to 1440p and a 41% loss from 1440p to 4K. This steeper falloff at High settings compared to Medium suggests that the additional shading work at higher quality presets amplifies the GPU's workload more than the resolution change alone.

Low settings show the most dramatic scaling behavior. The system delivers 110 FPS at 1080p, 97 FPS at 1440p, and 57 FPS at 4K. The 1080p to 1440p drop is relatively mild at 12%, but the 1440p to 4K drop is severe at 41%. This pattern hints that at Low settings, the GPU is less saturated at lower resolutions, allowing the CPU to push higher frame rates, but the 4K pixel count overwhelms the Radeon RX 6600 regardless of settings.

Ultra settings produce the lowest numbers across all resolutions: 78 FPS at 1080p, 54 FPS at 1440p, and 32 FPS at 4K. The 1080p Ultra result sits just 4 FPS below the High preset, indicating that the Ultra preset's additional effects do not cost much at that resolution. At 4K, however, the Ultra and High presets converge to nearly identical results, 32 FPS and 33 FPS respectively, which confirms that the GPU has reached its throughput ceiling and further visual quality settings cannot be compensated for.

The data indicates that 1080p is the comfortable operating range for this combo, with all presets maintaining playable averages. At 1440p, Medium and High remain viable, but the 4K results fall below 60 FPS across every preset, making that resolution impractical for smooth gameplay. The limiting component at 4K is clearly the GPU, as the CPU's workload does not scale with resolution in a way that would explain these frame rates.

CPU Role

The AMD Ryzen 5 2600 operates with six cores and twelve threads, using a base clock of 3.40 GHz and a boost clock of 3.90 GHz. This processor belongs to the 2000 series, built on the Zen architecture with a 12 nm process from GlobalFoundries. The chip carries 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache, which provides a solid foundation for gaming workloads.

The CPU's benchmark results show a balanced profile. In Cinebench R15, it scores 1248 points in multi-core and 157.3 points in single-core tests. Geekbench results follow a similar pattern: 5648 multi-core and 1154 single-core. PassMark tests reveal strong integer math performance at 44518, floating point math at 22942, and a multithread score of 13160. The single-thread PassMark score of 2239 indicates that individual core performance is modest by modern standards, but Thief's engine does not appear to demand exceptionally high single-core throughput.

The Ryzen 5 2600 sits at the 75th percentile among all CPUs in the database, with an average benchmark score of 21484. Its nearest rivals in the database include the Intel Core Ultra 5 228V, which scores 21440 and trails by 0.2%, and the Intel Core i9-11900H at 21367, which is 0.5% behind. The AMD EPYC 9454 scores 21223, placing it 1.2% behind the Ryzen 5 2600, while the Intel Xeon D-1746TER scores 21635, leading by 0.7%. These rivals are spread across mobile, desktop, and server segments, yet all land within a narrow band of the Ryzen 5 2600's aggregate performance.

The absence of a meaningful CPU bottleneck in Thief is evident from the frame rate behavior. At 1080p Low, the system reaches 110 FPS, which is a high enough figure that a weaker processor would likely show limitations. The fact that the frame rate drops by only 12% moving to 1440p at Low settings, but by 41% moving to 4K, indicates that the CPU is not the limiting factor at higher resolutions. The processor's 65 W TDP and dual-channel DDR4 memory support with 46.9 GB/s bandwidth are adequate for this game's requirements.

The Ryzen 5 2600's memory bandwidth of 46.9 GB/s, combined with its 16 MB shared L3 cache, provides sufficient data throughput for Thief's level streaming and AI routines. The game's stealth mechanics, which involve enemy patrols and line-of-sight checks, do not present the kind of massive parallel workload that would stress the CPU's twelve threads. The recorded data suggests that the processor operates well within its capabilities, leaving performance headroom that the GPU cannot exploit at higher resolutions.

GPU Role

The AMD Radeon RX 6600 uses the Navi 23 chip, built on RDNA 2.0 architecture with a 7 nm process from TSMC. The GPU contains 11,060 million transistors on a 237 mm² die, with a transistor density of 46.7 million per square millimeter. Its clock speeds include a base of 1626 MHz, a boost of 2491 MHz, and a game clock of 2044 MHz. The memory subsystem consists of 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth at 1750 MHz or 14 Gbps effective.

The GPU's compute resources include 1792 shading units, 112 texture mapping units, and 64 raster operation units. It also carries 28 ray tracing cores, though Thief's 2014 engine does not utilize ray tracing, so these cores remain idle during gameplay. The pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s define the card's fillrate capabilities, which directly influence the resolution scaling observed in the measured data.

The Radeon RX 6600's benchmark scores place it at the 63rd percentile among all GPUs, with an average score of 19036. Its nearest rivals include the NVIDIA Quadro K6000 at 19030, a 0% difference, and the NVIDIA GeForce RTX 4050 Mobile at 19049, which leads by 0.1%. The NVIDIA Tesla K20m scores 19089, ahead by 0.3%, while the NVIDIA RTX 2000 Ada Generation trails at 18954, a 0.4% deficit. These rivals span professional and mobile segments, yet the RX 6600 holds its own in aggregate benchmarks.

In DirectX tests, the RX 6600 scores 197 in DirectX 9, 152 in DirectX 11, and 51 in DirectX 12. The PassMark G3D score of 15096 and G2D score of 889 provide additional context. The GPU compute score of 6554 reflects its general compute capability. Thief, released in 2014, primarily relies on DirectX 11 rendering paths, which aligns with the card's strongest DirectX performance.

The 8 GB VRAM capacity is not a limiting factor in Thief, as the game's textures and geometry fit comfortably within that buffer at all tested resolutions. The 128-bit memory bus and 224.0 GB/s bandwidth, however, become increasingly restrictive as resolution rises. At 4K, the pixel fillrate required to maintain 60 FPS exceeds what the card can deliver, as shown by the 33 FPS average at High settings. The 4K Ultra result of 32 FPS, nearly identical to High, confirms that the GPU is saturated and additional settings have negligible impact.

The card's 132 W TDP and PCIe 4.0 x8 interface are consistent with its mid-range positioning. The dual-slot design, 190 mm length, and single 8-pin power connector indicate a straightforward installation profile. The suggested power supply of 300 W reflects the card's modest power draw, which aligns with its performance class.

How This Combo Ranks

The combination of the AMD Ryzen 5 2600 and AMD Radeon RX 6600 ranks 2993 out of 3720 tested combos in the database for Thief. This places the pairing in the lower portion of the ranking, meaning approximately 80% of tested CPU and GPU combinations deliver higher frame rates in this game. The rank reflects the age of the CPU and the mid-range positioning of the GPU relative to the full spectrum of tested hardware.

The ranking position is driven primarily by the GPU's performance ceiling rather than the CPU's capabilities. The Ryzen 5 2600's 75th percentile standing among CPUs shows that the processor is not the weak link in this pairing. The Radeon RX 6600's 63rd percentile GPU ranking is lower, and when paired with a six-core processor from 2018, the combined result lands in the 2993rd position. The gap between the CPU's percentile and the combo's rank suggests that the GPU holds back the overall result more than the CPU does.

Compared to other combos in the database, this pairing delivers playable performance at 1080p across all presets, with the lowest result being 78 FPS at Ultra. At 1440p, the system remains viable for Medium and High settings, but the 4K results are all below 60 FPS. The ranking position of 2993 out of 3720 indicates that many newer or higher-tier combinations achieve better results, but the data also shows that this combo is far from the bottom of the list, with 727 combinations ranking below it.

The combo's performance in Thief specifically is influenced by the game's age and rendering requirements. A 2014 title with DirectX 11 focus does not stress modern multi-core processors heavily, which benefits the Ryzen 5 2600. The GPU, however, must still render the game's detailed environments and lighting, and the RX 6600's 8 GB VRAM and 128-bit bus are adequate for 1080p but insufficient for high-refresh 4K play. The resulting rank of 2993 reflects this balance of strengths and weaknesses.

Measured FPS Breakdown

At 1920x1080, the recorded data shows the following average frame rates: Low settings deliver 110 FPS, Medium settings deliver 99 FPS with a minimum of 84 and maximum of 114, High settings deliver 82 FPS, and Ultra settings deliver 78 FPS. The spread between Low and Ultra is 32 FPS, indicating that visual quality presets have a moderate impact at this resolution. The Medium preset's frame time data shows a 30 FPS range, which is the widest spread recorded at any resolution and setting combination.

At 2560x1440, the averages are: Low at 97 FPS, Medium at 74 FPS with a minimum of 63 and maximum of 85, High at 56 FPS, and Ultra at 54 FPS. The gap between Low and Ultra narrows to 43 FPS, and the Medium preset's range tightens to 22 FPS. The 1440p results show that Low settings remain above 90 FPS, but the higher presets fall below 60 FPS, with High and Ultra both settling in the mid-50s.

At 3840x2160, the averages drop to: Low at 57 FPS, Medium at 44 FPS with a minimum of 37 and maximum of 50, High at 33 FPS, and Ultra at 32 FPS. The Low preset is the only 4K configuration that approaches 60 FPS, and it still falls short. The Medium preset's frame time range narrows to 13 FPS, showing that the GPU's consistent saturation at 4K produces smoother frame pacing even at lower average rates. The High and Ultra results, 33 and 32 FPS respectively, are nearly identical, confirming that the GPU cannot differentiate between these presets at 4K.

Comparing presets across resolutions, the Low setting shows the smallest absolute drop from 1080p to 1440p, from 110 to 97 FPS, but the largest percentage drop from 1440p to 4K, from 97 to 57 FPS. The Ultra setting shows a more linear decline: 78 to 54 to 32 FPS. The Medium setting's frame time data at 1080p shows a 30 FPS range, at 1440p a 22 FPS range, and at 4K a 13 FPS range. This narrowing range at higher resolutions indicates that the GPU becomes the sole limiter, reducing frame time variance as it operates at full capacity.

The overall data set shows that this combo's sweet spot is 1080p with any preset, 1440p with Low or Medium settings, and 4K only at Low settings with a 57 FPS average that still falls below 60. The measured results provide a clear picture of a system that can handle Thief comfortably at mainstream resolutions but cannot sustain high frame rates at 4K, with the GPU consistently acting as the performance boundary.
