Thief

How This Combo Ranks

The AMD Ryzen 5 9600X paired with the NVIDIA GeForce GTX 1070 places at rank 1408 out of 1642 tested combinations in Thief. This puts the combo in the lower 15% of all tested systems, which is a telling position given the game's age relative to the components. The ranking reflects a substantial bottleneck: the GTX 1070, which sits at the 51st percentile among all GPUs, is tasked with driving a 2014 title that was designed for hardware of its era. The CPU, by contrast, is a modern part that ranks in the 85th percentile among all processors, with an average benchmark score of 28246. This asymmetry between the two components' capabilities is the defining characteristic of this pairing.

Looking at the CPU's nearest rivals, the Ryzen 5 9600X scores 0.3% higher than the Intel Core i5-13490F and 0.3% higher than the AMD Ryzen 5 230. It trails the AMD Ryzen 7 8845HS by 0.4% and the Intel Core i5-14500T by 0.5%. These margins are negligible, indicating that the processor is performing exactly as expected for its class. The GPU side tells a similar story: the GTX 1070's average benchmark score of 12331 places it just 0.7% above the NVIDIA Quadro K4200, while it sits 1.3% below the GeForce GTX 880M and 1.4% below the GeForce GTX 1650 SUPER. The GPU is firmly in the middle of the pack, neither overperforming nor underwhelming relative to its direct competitors.

The combination's low overall rank in Thief suggests that the game's engine is heavily sensitive to graphics throughput, and the GTX 1070's mid-range standing becomes the limiting factor. The measured frame rates confirm this: at 1080p Ultra, the combo produces 68.2 FPS, which is playable but far from the high-refresh territory that the CPU alone could enable. The rank of 1408 out of 1642 is not a condemnation of either part individually, but rather a reflection of how the GPU's Pascal architecture, released in 2016, interacts with a game from 2014 that was optimized for different hardware generations.

GPU Role

The NVIDIA GeForce GTX 1070 is built on the GP104 chip using the 16 nm Pascal architecture, a design that has been end-of-life for several years. Its 8 GB of GDDR5 memory on a 256-bit bus delivers a bandwidth of 256.3 GB/s, which is sufficient for Thief's texture-heavy environments at most settings. The memory clock runs at 2002 MHz, translating to 8 Gbps effective, and the 1920 shading units are organized into 120 texture mapping units and 64 raster output units. The base clock of 1506 MHz boosts to 1683 MHz, providing a pixel rate of 107.7 GPixel/s and a texture rate of 202.0 GTexel/s. These specifications place the card at 6.463 TFLOPS of FP32 compute, which is modest by modern standards but was respectable for its launch period.

In Thief specifically, the GPU's role is dominant across all resolutions. The data shows that the GTX 1070's performance ceiling is reached early: at 4K Ultra, the combo manages only 27.8 FPS, which falls below the threshold for smooth gameplay. The card's 8 GB frame buffer is not the constraint here; rather, the raw shading and rasterization throughput limit the engine's ability to render the game's dynamic lighting and shadow effects. The 16 nm process and 7,200 million transistors on a 314 mm² die are simply not sufficient for 4K Ultra in this title. The GPU's percentile rank of 51 among all GPUs underscores that this is a middle-of-the-road part, and Thief's results align with that positioning.

The relationship between GPU clocks and frame rates is evident when comparing settings at the same resolution. At 1440p, dropping from Ultra to High improves the average FPS from 47.5 to 50.3, a modest gain, while dropping to Medium yields 64.5 FPS and Low reaches 89.6 FPS. This scaling pattern indicates that the GPU is the primary bottleneck, as the CPU's 6 cores and 12 threads with a boost clock of 5.40 GHz are more than capable of feeding the graphics pipeline. The GTX 1070's 64 ROPs and 120 TMUs are the limiting factors, particularly at higher settings where the game's post-processing effects increase the per-pixel workload.

Settings Recommendations

The measured FPS data provides a clear picture of which settings deliver the best experience for this combo. At 1080p, the most common resolution for this class of hardware, the Ultra preset produces 68.2 FPS, which is playable but not ideal for a stealth game where smooth camera movement matters. The High preset improves this to 73.2 FPS, while Medium reaches 94.9 FPS and Low hits 126.3 FPS. Given that Thief relies on atmospheric lighting and shadow detail for its stealth mechanics, the High preset at 1080p offers the best balance: it maintains a frame rate above 70 FPS while preserving enough visual fidelity to keep the game's moody environments intact. The jump from High to Ultra costs 5 FPS for what is typically a marginal visual gain in this title, making Ultra less attractive.

At 1440p, the situation changes. The High preset delivers 50.3 FPS, which is borderline for smooth gameplay, while Medium provides 64.5 FPS and Low reaches 89.6 FPS. The Ultra preset falls to 47.5 FPS, which is below the 50 FPS threshold that many players consider the minimum for acceptable responsiveness. For 1440p, the Medium preset is the recommended choice: it offers a 14.2 FPS improvement over High while still retaining enough graphical detail to appreciate the game's art direction. The drop from High to Medium is noticeable but far less impactful than the drop from Medium to Low, which sacrifices too much ambient occlusion and shadow quality for a stealth game.

At 4K, the options are limited. The High preset produces 30.5 FPS, which is playable for a slower-paced game but not ideal. The Medium preset yields 41 FPS, which is the only setting that approaches a smooth experience at this resolution, while Low reaches 51.6 FPS and Ultra falls to 27.8 FPS. For 4K, the Medium preset is the practical ceiling: it provides a playable frame rate without the severe visual degradation of Low. The Ultra preset is effectively unplayable, and High is marginal at best. The data suggests that 4K is not the intended use case for this GPU, but for those who insist on it, Medium is the only sensible option.

Measured FPS Breakdown

The measured frame rates across all resolutions and settings reveal a consistent pattern of GPU-bound performance. At 1080p, the combo achieves 126.3 FPS on Low, 94.9 FPS on Medium, 73.2 FPS on High, and 68.2 FPS on Ultra. The gap between Low and Medium is 31.4 FPS, while the gap between High and Ultra is only 5 FPS, indicating diminishing returns at the top end. The 1080p results are all above the 60 FPS threshold except for Ultra, which barely clears it. This resolution is clearly where the combo is most comfortable, offering a wide range of playable settings.

Moving to 1440p, the frame rates drop significantly. Low produces 89.6 FPS, Medium 64.5 FPS, High 50.3 FPS, and Ultra 47.5 FPS. The drop from Low to Medium is 25.1 FPS, while the drop from High to Ultra is just 2.8 FPS. The 1440p results show that the GPU begins to struggle at the higher settings, with High and Ultra both falling below the 60 FPS mark. The 42.1 FPS difference between Low and Ultra at this resolution highlights how sensitive the GTX 1070 is to the game's graphical demands as pixel count increases.

At 4K, the results are the most constrained. Low produces 51.6 FPS, Medium 41 FPS, High 30.5 FPS, and Ultra 27.8 FPS. The gap between Low and Medium is 10.6 FPS, while High and Ultra are separated by just 2.7 FPS. The 4K data shows that even the lowest settings only achieve a barely playable frame rate, and the higher settings are all below 31 FPS. The 23.8 FPS difference between Low and Ultra at this resolution is the largest absolute drop across all resolutions, underscoring the GPU's inability to handle the pixel count at higher detail levels.

Resolution Scaling

The scaling from 1080p to 4K reveals the extent to which the GPU limits this combo. At Low settings, the frame rate drops from 126.3 FPS at 1080p to 89.6 FPS at 1440p, a 29.1% reduction, and then to 51.6 FPS at 4K, a further 42.4% reduction from 1440p. The total drop from 1080p to 4K at Low is 74.7 FPS, representing a 59.1% decrease. At Medium settings, the progression is 94.9 FPS to 64.5 FPS to 41 FPS, with the 1080p-to-1440p drop being 32.0% and the 1440p-to-4K drop being 36.4%. The total decline from 1080p to 4K at Medium is 53.9 FPS, or 56.8%.

At High settings, the scaling shows a steeper decline: 73.2 FPS at 1080p drops to 50.3 FPS at 1440p, a 31.3% reduction, and then to 30.5 FPS at 4K, a 39.4% reduction from 1440p. The total drop is 42.7 FPS, a 58.3% decrease. At Ultra settings, the pattern is similar but with lower absolute values: 68.2 FPS at 1080p falls to 47.5 FPS at 1440p, a 30.4% reduction, and then to 27.8 FPS at 4K, a 41.5% reduction. The total decline is 40.4 FPS, a 59.2% decrease.

These scaling patterns are remarkably consistent across all settings, with the percentage drops from 1080p to 4K clustering between 56.8% and 59.2%. This uniformity indicates that the bottleneck is purely pixel-throughput-bound, with the GPU's shading and ROP capabilities being the sole constraint. The CPU, with its 32 MB of shared L3 cache and DDR5 memory support providing 89.6 GB/s of bandwidth, is not contributing to the scaling behavior. The fact that the frame rate scales almost linearly with pixel count, rather than showing signs of CPU limitation at lower resolutions, confirms that the GTX 1070 is the definitive limiting component in this pairing. At 1080p, the CPU could push much higher frame rates than the GPU allows, but the GPU's ceiling caps the system's performance at every resolution and setting combination.
