Thief

Resolution Scaling

The measured FPS data for Thief with the AMD Ryzen 5 5600X and AMD Radeon RX 9070 reveals a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo delivers 165.4 FPS, but dropping to 1440p Low reduces that to 148.1 FPS, and at 4K Low the average falls to 96.6 FPS. This represents a 41.6% performance drop from 1080p Low to 4K Low, indicating that the rendering load at higher resolutions begins to outpace what the GPU can sustain.

The scaling becomes more pronounced at higher quality presets. With Ultra settings, the frame rate goes from 131.8 FPS at 1080p to 92.9 FPS at 1440p, and then down to 50.5 FPS at 4K. That 4K Ultra result is less than half the 1080p Ultra figure, which strongly suggests the Radeon RX 9070 is the limiting component at these settings. The gap between 1440p Ultra (92.9 FPS) and 4K Ultra (50.5 FPS) is a 45.6% reduction, a steeper decline than the 37.2% drop seen from 1080p Ultra to 1440p Ultra.

Interestingly, the High preset shows a similar pattern but with more headroom. At 1080p High, the combo hits 132.4 FPS; at 1440p High, it manages 97.8 FPS; and at 4K High, it falls to 58.7 FPS. The 4K High result remains above 60 FPS territory, but barely, and the trend indicates that any resolution above 1440p will push the GPU to its limits. The data implies that for 4K gaming, the CPU has ample capacity, but the GPU's pixel throughput at 3840x2160 becomes the dominant constraint.

FAQ

CPU Role

The AMD Ryzen 5 5600X brings 6 cores and 12 threads, built on the Zen 3 architecture with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. Its 32 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth contribute to its overall capability. In synthetic benchmarks, the processor scores 2,622 in Cinebench R23 single-core and 18,578 in multi-core, while Geekbench shows 2,111 single-core and 8,673 multi-core. These figures position the CPU with a percentile rank of 78 against all CPUs, meaning it outperforms the majority of tested processors.

For Thief, a game released in 2014, the CPU's single-thread performance is particularly relevant. The game's engine likely relies on fewer threads, so the 5600X's strong single-core score of 917 in 3DMark single-thread suggests it can handle the game's logic without becoming a bottleneck. The measured FPS data supports this: at 1080p Low, the combo reaches 165.4 FPS, which is close to the 3DMark 2-thread score of 1,793, indicating that the CPU is not limiting at lower resolutions. However, at 4K Ultra, the frame rate drops to 50.5 FPS, a level where the GPU's workload dominates, and the CPU's role becomes secondary.

The nearest rivals to the 5600X include the AMD Ryzen 5 5600GT (average score 20,740, delta -0.3%), Intel Core i7-10700 (20,746, -0.3%), and Intel Core i5-12490F (20,794, -0.5%). These deltas are all within 1% of the 5600X's average benchmark score of 20,680, showing that the CPU performs nearly identically to those alternatives. In Thief, the 5600X's 12 threads provide headroom for background tasks, but the game's frame rates are far more sensitive to GPU changes, as evidenced by the scaling patterns.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600X and AMD Radeon RX 9070 ranks 513th out of 1,642 tested combos in Thief. This places it in the 68.8th percentile of all configurations, meaning 68.8% of tested combos perform worse. The rank suggests a capable pairing that sits comfortably above the median, but it is not among the top-tier setups. Given that the GPU has a percentile rank of 79 against all GPUs and the CPU has a percentile rank of 78, the combo's in-game ranking is slightly lower than either component's individual standing, implying that Thief's engine may not fully utilize the hardware.

Compared to other combos, the 513th position indicates that there are 1,129 pairings that achieve higher frame rates. This is likely due to Thief being an older title where newer GPUs may not show their full potential, or where the CPU-GPU balance is less critical than in modern games. The data shows that the combo's 4K Ultra result of 50.5 FPS is below the 60 FPS threshold, which might explain why it ranks lower than combos with faster GPUs or better-optimized pairings.

The GPU's nearest rivals include the NVIDIA A2 (average score 34,866, delta -0.2%), NVIDIA Quadro GV100 (34,677, +0.3%), AMD Radeon HD 7970 (34,541, +0.7%), and AMD Radeon PRO W6400 (34,511, +0.8%). These deltas are small, but the RX 9070's average benchmark score of 34,780 is slightly above most of these, yet the in-game rank suggests Thief may not scale perfectly with the GPU's compute capabilities.

Settings Recommendations

For the best experience per the measured rows, the Medium preset offers the most balanced performance across resolutions. At 1080p Medium, the combo delivers 149.9 FPS, which is only 9.4% lower than Low but provides better visual quality. At 1440p Medium, 127.8 FPS remains well above the 60 FPS threshold, and even at 4K Medium, 73.1 FPS is playable. The jump from Medium to High at 1440p costs 30 FPS (from 127.8 to 97.8), which is a significant trade-off for marginal visual gains.

If prioritizing frame rate, Low is the clear choice, with 165.4 FPS at 1080p and 148.1 FPS at 1440p. However, at 4K, Low (96.6 FPS) is the only preset that stays above 90 FPS, making it the recommended setting for 4K displays. High at 4K drops to 58.7 FPS, which may cause stuttering on some displays, while Ultra at 4K falls to 50.5 FPS, below the 60 FPS standard. For users with 1440p monitors who want a mix of quality and speed, Medium appears optimal, as it retains 127.8 FPS while offering better textures and effects than Low.

Ultra is only recommended for 1080p, where it achieves 131.8 FPS. At 1440p Ultra, the 92.9 FPS result is still acceptable, but the 4K Ultra figure of 50.5 FPS fails to meet the 60 FPS target. The data suggests that Ultra is best suited for 1080p gaming, while Medium is the sweet spot for 1440p and 4K.

Measured FPS Breakdown

At 1920x1080, the combo produces 165.4 FPS on Low, 149.9 FPS on Medium, 132.4 FPS on High, and 131.8 FPS on Ultra. The difference between High and Ultra is negligible at just 0.6 FPS, indicating that Ultra adds little over High at this resolution. The spread from Low to Ultra is 33.6 FPS, with the largest single drop occurring between Medium and High at 17.5 FPS.

At 2560x1440, the results are 148.1 FPS on Low, 127.8 FPS on Medium, 97.8 FPS on High, and 92.9 FPS on Ultra. The gap between Low and Medium is 20.3 FPS, while Medium to High is a 30 FPS drop, the steepest penalty among all presets at this resolution. High and Ultra are again close, with only 4.9 FPS separating them.

At 3840x2160, the figures fall to 96.6 FPS on Low, 73.1 FPS on Medium, 58.7 FPS on High, and 50.5 FPS on Ultra. The drop from Medium to High is 14.4 FPS, and from High to Ultra is 8.2 FPS. Notably, 4K Low is the only 4K preset that exceeds 90 FPS, and 4K Medium is the last preset above 60 FPS.

Comparing across resolutions, the 1080p to 1440p drop for Low is 17.3 FPS (from 165.4 to 148.1), while the 1440p to 4K drop is 51.5 FPS (from 148.1 to 96.6). This shows that the GPU's performance degrades more sharply as resolution increases, reinforcing the GPU-bound nature of the pairing.

GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with a Navi 48 chip, manufactured on a 4 nm process at TSMC. It features 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s of bandwidth. The GPU has 3,584 shading units, 224 texture mapping units, and 128 raster operations pipelines, with 56 ray tracing cores. Its clocks are 1,330 MHz base, 2,070 MHz game, and 2,520 MHz boost, delivering 36.13 TFLOPS of FP32 performance. The 220 W TDP and dual-slot design require a 550 W suggested PSU, and the card connects via PCIe 5.0 x16.

In benchmark tests, the RX 9070 scores 25,381 in Passmark G3D and 13,3741 in Geekbench OpenCL, with a percentile rank of 79 against all GPUs. Its average benchmark score of 34,780 places it slightly above rivals like the NVIDIA A2 (34,866, -0.2%) and Quadro GV100 (34,677, +0.3%). However, in Thief, the GPU's role is constrained by the game's age and rendering requirements. The 4K Ultra result of 50.5 FPS indicates that the GPU is the limiting factor at high resolutions, as the CPU can clearly handle lower resolution workloads.

The 16 GB VRAM is more than sufficient for Thief, which was released in 2014 and likely uses less than 4 GB even at 4K. The GPU's high pixel rate of 322.6 GPixel/s and texture rate of 564.5 GTexel/s should theoretically support high frame rates, but the measured data shows that 4K Ultra falls below 60 FPS. This suggests that Thief's engine may not fully leverage the RDNA 4.0 architecture's strengths, or that the game is optimized for older hardware. The 1080p results, where Low hits 165.4 FPS, show the GPU's raw capability, but the scaling to 4K reveals diminishing returns as pixel count quadruples.
