Thief

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 6600 delivers a highly playable experience in Thief, though the data reveals a clear progression of bottlenecks as resolution increases. At 1920x1080, the combination is exceptionally strong, with average frame rates ranging from 80.8 FPS at Ultra settings to 144.3 FPS at Low settings. The jump from Low to Medium at 1080p costs 36.9 FPS (from 144.3 to 107.4), while the transition from High to Ultra is comparatively mild, dropping from 82.5 FPS to 80.8 FPS. This pattern indicates that at 1080p, the CPU is well ahead of the GPU’s demands, allowing the graphics card to be the primary limiter even at lower settings.

Moving to 2560x1440, the frame rates scale down predictably but remain smooth. The Low setting produces 99.9 FPS, which is still well above typical refresh rate targets, while Medium delivers 74.9 FPS and High drops to 59.6 FPS. Ultra at 1440p yields 53.7 FPS, showing a moderate 11.1% reduction from the High preset. The gap between Low and Medium at this resolution is 25 FPS (from 99.9 to 74.9), which is smaller than the 36.9 FPS gap seen at 1080p, suggesting that the GPU is beginning to take on more of the workload as pixel count rises. At 3840x2160, the scaling becomes steep: Low produces 60.9 FPS, Medium drops to 45.2 FPS, High falls to 35.9 FPS, and Ultra bottoms out at 29.8 FPS. The delta between Low and Ultra at 4K is 31.1 FPS, indicating that the RX 6600 is heavily taxed by the higher resolution, with the CPU no longer the deciding factor.

The data points to a system that is CPU-bound at 1080p, transitioning to a GPU-bound state at 1440p and fully GPU-limited at 4K. The 5800X’s 8-core, 16-thread configuration with a boost clock of 4.70 GHz provides ample headroom for the game’s logic, evidenced by the minimal performance difference between High and Ultra at 1080p (1.7 FPS). In contrast, the 4K Ultra result of 29.8 FPS is only 41% of the 1080p Ultra figure, highlighting the GPU’s inability to maintain performance as resolution scales.

Resolution Scaling

The measured FPS data shows a classic resolution scaling curve for this combo. From 1080p to 1440p, the average frame rate across all settings drops by approximately 27-31%, while the jump from 1440p to 4K results in a further 39-46% reduction. Specifically, at High settings, the sequence is 82.5 FPS (1080p) → 59.6 FPS (1440p) → 35.9 FPS (4K), representing declines of 27.8% and 39.8% respectively. At Low settings, the drop is 144.3 → 99.9 → 60.9 FPS, with the 4K figure being just 42.2% of the 1080p result.

This scaling pattern indicates that the limiting component shifts with resolution. At 1080p Low, the 144.3 FPS result is likely near the CPU’s maximum output for this game, as the GPU has relatively little work to do. As resolution increases, the GPU’s fill-rate and memory bandwidth constraints become more prominent. The RX 6600’s 8 GB of GDDR6 memory on a 128-bit bus with 224.0 GB/s bandwidth is sufficient for 1080p and 1440p, but at 4K Ultra, the data shows the system struggling to maintain 30 FPS. The fact that 4K Low (60.9 FPS) is nearly double 4K Ultra (29.8 FPS) underscores how much the GPU’s shading units and ROPs (64) are stressed by higher quality presets at that resolution.

The 1080p Ultra result of 80.8 FPS being lower than 1440p High (59.6 FPS) is expected, but the margin between them is only 21.2 FPS, suggesting that the CPU is still contributing at 1440p. The largest single-step drop occurs from 1440p Medium to 4K Medium (74.9 → 45.2 FPS, a 39.7% reduction), which aligns with the GPU becoming the sole bottleneck. Overall, the data suggests that for this game, the sweet spot for this combo is 1080p or 1440p with high settings, while 4K requires dropping to Low or Medium to stay fluid.

GPU Role

The AMD Radeon RX 6600 is the primary driver of frame rate differences across settings, with its clock speeds and memory configuration playing a decisive role at higher resolutions. The GPU has a base clock of 1626 MHz and a boost clock of 2491 MHz, with a game clock of 2044 MHz. These clocks, combined with 1792 shading units and 112 TMUs, produce a texture rate of 279.0 GTexel/s and a pixel rate of 159.4 GPixel/s. In Thief, the impact of these specifications is visible in the scaling from Medium to Ultra at each resolution.

At 1080p, the difference between Medium (107.4 FPS) and Ultra (80.8 FPS) is 26.6 FPS, which is a 24.8% reduction. At 1440p, the same settings gap is 21.2 FPS (74.9 → 53.7), and at 4K, it is 15.4 FPS (45.2 → 29.8). The shrinking absolute difference at higher resolutions indicates that the GPU is already saturated, and additional quality settings have diminishing returns. The 8 GB VRAM capacity is not a limiting factor at 1080p or 1440p, but at 4K Ultra, the combination of memory bandwidth (224.0 GB/s) and the 128-bit bus likely contributes to the sub-30 FPS result.

The GPU’s FP32 performance of 8.928 TFLOPS is modest for a 4K workload, and the benchmark results reflect this. The RX 6600’s passmark G3D score is 15096, and its percentile rank of 69 places it in the mid-range tier. In comparison to its nearest rival, the AMD Radeon 890M, the RX 6600 has a 0% deltaPct, meaning they perform identically in synthetic benchmarks. The NVIDIA GeForce RTX 3060 Ti scores 0.5% higher on average, but the RX 6600’s boost clock of 2491 MHz is the key to maintaining competitive performance in a game like Thief, which benefits from raw clock speed rather than ray tracing features.

The GPU’s DirectX 12 Ultimate support and Vulkan 1.4 API compatibility do not appear to offer a unique advantage for this title, as the measured FPS shows a steady decline with each preset increase. The 14 Gbps effective memory speed is adequate for 1080p and 1440p, but the 4K results suggest that the memory subsystem is a bottleneck, with the bus width limiting data throughput.

How This Combo Ranks

The combination of the AMD Ryzen 7 5800X and the AMD Radeon RX 6600 ranks 1312 out of 1642 tested combos in Thief, placing it in the 80th percentile of all tested systems. This rank reflects a configuration that is solidly mid-pack, but not top-tier. The CPU alone has an 84th percentile ranking among all CPUs, with an average benchmark score of 27606, while the GPU has a 69th percentile ranking with an average score of 25235. The combo rank of 1312 is lower than both individual component percentiles, which indicates that the pairing is slightly imbalanced for this particular game.

Examining the CPU’s nearest rivals, the AMD Ryzen 7 5800 scores 0.3% higher on average, while the AMD Ryzen 5 8500GE and Intel Core i7-13700H both score 0.4% lower. The Intel Core i5-12600KF is 0.8% ahead. These deltas are within noise, meaning the 5800X is not the differentiator in this combo. For the GPU, the AMD Radeon 890M is exactly 0% different, the RX 580 2048SP is 0.2% lower, the RX 6700M is 0.2% higher, and the RTX 3060 Ti is 0.5% higher. This suggests that swapping the RX 6600 for a slightly faster GPU would yield only marginal gains.

The combo’s rank of 1312 out of 1642 means that 330 other combos perform better, which is expected given the RX 6600’s mid-range positioning. However, the measured FPS data shows that this combo is still highly capable for Thief at 1080p and 1440p, with all settings except 4K Ultra remaining above 30 FPS. The data indicates that the combo is more CPU-heavy than GPU-heavy, as the 5800X’s 3DMark scores (e.g., 7586 for 16 threads) are strong, but the GPU’s passmark G3D score of 15096 is the limiting factor for higher resolutions.
