Thief

Resolution Scaling

The measured FPS data for Thief reveals a predictable but steep drop as resolution climbs. At 1080p with Low settings, this combo produces 126 FPS, which falls to 107.9 FPS at 1440p and then to 65.8 FPS at 4K. That is a 47.8% decline from 1080p to 4K at Low settings. The scaling curve tightens considerably when moving to higher presets. At Ultra settings, the frame rate goes from 88 FPS at 1080p to 56.9 FPS at 1440p, and finally to 37.7 FPS at 4K — a 57.2% total reduction from the 1080p baseline.

The pattern indicates a growing GPU bottleneck at higher resolutions. At 1080p, the difference between Low and Ultra is 38 FPS, a substantial range that suggests the CPU can still feed frames quickly when the workload is light. At 4K, the gap between Low and Ultra narrows to 28.1 FPS, with the Ultra preset barely holding above 30 FPS. The data shows that 4K High and Ultra settings both land in the mid-to-high 30s, which is the boundary of playability for a stealth title. The 4K Ultra result of 37.7 FPS and 4K High result of 36.8 FPS are nearly identical, indicating that the GPU has hit a hard ceiling around 37 FPS regardless of minor setting changes.

The 1440p results tell a more balanced story. Medium settings deliver 78.5 FPS, which is a comfortable margin above the 60 FPS threshold. High settings at 1440p produce 59.7 FPS, just shy of that mark. The resolution scaling from 1080p to 1440p at Medium shows a 37.4 FPS drop, while the same resolution step at Low shows only an 18.1 FPS drop. This asymmetry suggests that the GPU's shading units and memory bandwidth become the limiting factor once the pixel count increases, regardless of the preset tier.

How This Combo Ranks

The combination of the AMD Ryzen 5 3600 and AMD Radeon RX 6600 XT ranks 1261 out of 1642 tested combos in Thief. That places this pairing in the lower-middle portion of the database, which is notable given the hardware's individual standing. The CPU sits at the 76th percentile among all processors, while the GPU ranks at the 71st percentile among all graphics cards. The disparity between component percentiles and the combo rank suggests that Thief does not heavily favor this specific pairing.

The CPU's nearest rivals in the broader benchmark database include the Intel Core i5-11400 at a delta of -0.1%, the AMD Ryzen 5 7535HS at +0.2%, the AMD Ryzen 5 1600 at -0.2%, and the AMD EPYC 9274F at -0.3%. These deltas are all within a fraction of a percent, indicating that the Ryzen 5 3600 sits in a tightly clustered performance band where no single rival holds a meaningful advantage. The GPU's nearest rivals are similarly close: the NVIDIA GeForce GTX 980 Ti at +0.1%, the AMD Radeon R9 M395X at +0.4%, the NVIDIA GeForce RTX 3070 at -0.9%, and the AMD FirePro S7150 at -1.5%.

The rank of 1261 out of 1642 means that roughly 23% of tested combos perform worse in Thief. This is a game from 2014, and the data shows that modern mid-range hardware does not achieve top-tier results. The CPU's 6 cores and 12 threads, combined with the GPU's 8 GB of VRAM, produce frame rates that are playable but not exceptional. The combo's position in the database reflects a pairing that is adequate for this title at lower resolutions but struggles to maintain high frame rates at 4K.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with the Navi 23 chip. It features 8 GB of GDDR6 memory on a 128-bit bus, yielding a memory bandwidth of 256.0 GB/s. The GPU's base clock is 1968 MHz, with a boost clock of 2589 MHz and a game clock of 2359 MHz. These clocks are high for the RDNA 2 generation, and the boost clock in particular helps sustain performance in sustained workloads.

The GPU's 2048 shading units, 128 texture mapping units, and 64 render output units provide a solid foundation for a game like Thief, which is not particularly demanding by modern standards. The pixel rate of 165.7 GPixel/s and texture rate of 331.4 GTexel/s are sufficient for 1080p and 1440p gaming. The FP32 performance of 10.60 TFLOPS places this GPU in a competitive position against its nearest rivals, though the RTX 3070 shows a -0.9% delta in average benchmark score, indicating the NVIDIA card is slightly faster overall.

The 8 GB VRAM capacity is a critical factor at 4K. The measured FPS at 4K High (36.8 FPS) and 4K Ultra (37.7 FPS) are nearly identical, which points to a memory bandwidth or capacity limitation rather than a raw compute limit. The 256.0 GB/s bandwidth is adequate for 1080p, where the GPU delivers 92.7 FPS at High and 88 FPS at Ultra. At 4K, the same settings drop to roughly 37 FPS, a 60% reduction that aligns with the increased memory pressure from four times the pixel count. The GPU's 64 ROPs appear to be the bottleneck at 4K, as the pixel fill rate cannot keep up with the demand.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 126 FPS, Medium yields 115.9 FPS, High reaches 92.7 FPS, and Ultra falls to 88 FPS. The spread from Low to Ultra is 38 FPS, and the step from Medium to High is 23.2 FPS, which is the largest single-preset drop in the entire dataset. This suggests that High settings introduce a significant increase in shading complexity that the GPU must process.

At 2560x1440, the frame rates are 107.9 FPS at Low, 78.5 FPS at Medium, 59.7 FPS at High, and 56.9 FPS at Ultra. The drop from Low to Medium is 29.4 FPS, which is a substantial hit. The difference between High and Ultra narrows to just 2.8 FPS, indicating diminishing returns from the highest preset. The 1440p High result of 59.7 FPS is just below the 60 FPS target, making Medium the practical choice for smooth gameplay at this resolution.

At 3840x2160, the results are 65.8 FPS at Low, 48.4 FPS at Medium, 36.8 FPS at High, and 37.7 FPS at Ultra. The Low setting is the only one that clears 60 FPS at 4K. Medium drops to 48.4 FPS, which is playable but not fluid. High and Ultra both hover around 37 FPS, making them borderline for a stealth game where quick reaction times are less critical than in an action title. The 4K data shows that the GPU's performance ceiling is reached between Medium and High, with Ultra providing no additional cost in frame rate but also no benefit.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor built on the Zen 2 architecture with a 7 nm process. Its base clock is 3.60 GHz with a boost clock of 4.20 GHz. The CPU has 32 MB of shared L3 cache and 512 KB of L2 cache per core. The single-thread performance, as measured by 3DMark, is 696 points, while the 16-thread score is 4605 points. These figures indicate a balanced processor that can handle both lightly threaded and heavily threaded workloads.

In Thief, the CPU's role is evident in the 1080p Low result of 126 FPS. This is the highest frame rate in the dataset, and it suggests that the CPU can feed the GPU with enough frames to reach this level. The 3DMark single-thread score of 696 and the Cinebench R23 single-core score of 2124 both point to solid per-core performance. The CPU's boost clock of 4.20 GHz is the key enabler for this, as Thief's engine relies on a few primary threads for game logic and scene management.

The CPU's multi-threaded capabilities are less critical for Thief, but the 12 threads still contribute to consistent frame pacing. The Cinebench R23 multi-core score of 15045 shows that the CPU can handle substantial parallel workloads. The nearest rival, the Intel Core i5-11400, has an average benchmark score that is 0.1% lower than the Ryzen 5 3600, making them effectively identical in synthetic tests. The AMD Ryzen 5 7535HS is 0.2% higher, while the Ryzen 5 1600 is 0.2% lower.

The CPU's 65 W TDP and 3,800 million transistors on a 74 mm² die indicate an efficient design. The memory bandwidth of 51.2 GB/s via dual-channel DDR4 is sufficient for this game, as the measured FPS at 1080p Low (126 FPS) shows no obvious CPU bottleneck. However, the 4K results, which range from 65.8 FPS at Low to 37.7 FPS at Ultra, are clearly GPU-limited, as the CPU has ample headroom to push more frames if the GPU could render them. The data confirms that in Thief, the Ryzen 5 3600 is not the limiting component at any resolution above 1080p.
