Thief

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 5070 combination delivers a wide performance envelope in Thief, with frame rates that scale predictably across resolutions and settings. The measured data shows this pairing is capable of high refresh rates at 1080p and remains playable at 4K, though the performance curve reveals where each component’s influence is strongest.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial but not catastrophic, indicating a balanced system that gradually shifts from CPU-bound to GPU-bound behavior. At 1080p with Low settings, the combo produces 226.6 FPS. Moving to 1440p Low drops this to 187.6 FPS, a reduction of 39.0 FPS. At 4K Low, the average falls to 114.1 FPS, which is 112.5 FPS below the 1080p figure. This scaling pattern suggests that at lower resolutions and settings, the CPU has headroom to feed the GPU, but the RTX 5070 still manages to extract high frame rates.

The High preset tells a similar story. At 1080p, the average is 156.4 FPS. At 1440p, it drops to 108.7 FPS, a 47.7 FPS decline. At 4K, the average is 66.3 FPS, which is 90.1 FPS below the 1080p result. The percentage drop from 1440p to 4K is steeper than from 1080p to 1440p, which is typical for a GPU that begins to saturate its memory bandwidth and shading resources at higher pixel counts.

Ultra settings amplify this effect. The 1080p Ultra average is 149.1 FPS. At 1440p, it falls to 104.7 FPS. At 4K Ultra, the average is 63.7 FPS. The gap between 1080p and 4K Ultra is 85.4 FPS, which is a 57.3% reduction. This indicates that Thief’s Ultra preset imposes a significant load on the RTX 5070, particularly at 4K where the 12 GB VRAM and 192-bit memory bus are exercised heavily.

The limiting component at 4K is clearly the GPU. The RTX 5070’s 30.87 TFLOPS FP32 throughput and 672.0 GB/s memory bandwidth are sufficient for 60-plus FPS at High settings, but the Ultra preset at 4K barely holds above 60 FPS. At 1080p, the CPU’s role becomes more apparent, as the 12-core, 24-thread Ryzen 9 9900X with a 5.60 GHz boost clock can drive frame rates above 200 FPS in less demanding settings.

How This Combo Ranks

In the database of tested combinations, this pairing ranks 134 out of 1642 combos for Thief. This places it in the top 8.2% of all tested systems, which is a strong showing for a 2014-era title. The rank reflects the combo’s absolute performance, but the delta between settings is more informative.

The combo’s rank suggests that the Ryzen 9 9900X and RTX 5070 together outperform the vast majority of systems tested with this game. However, the rank is not in the top 50, which indicates that some combinations—likely those with even higher-end GPUs or more aggressive CPU tuning—can achieve better frame rates in Thief’s more demanding presets.

The CPU’s nearest rivals in synthetic benchmarks provide context. The AMD Ryzen 9 9900X3D scores 54681 on average, which is 0.4% higher than the 9900X’s 54450. The Intel Core Ultra 5 245K scores 55304, which is 1.5% higher. These deltas are small, meaning the 9900X is not leaving significant performance on the table relative to its closest competitors. The GPU’s nearest rivals show a similar pattern, with the RTX 5070’s 41687 average score sitting within 0.7% of the AMD Radeon Pro 580X and 0.6% of the RTX 3090.

For Thief specifically, the combo’s rank of 134 out of 1642 indicates that the measured FPS figures are competitive. The gap between the 1080p Low average of 226.6 FPS and the 4K Ultra average of 63.7 FPS shows a wide operating range, which is a hallmark of a system that can adapt to different display and quality preferences.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The CPU’s cache hierarchy includes 80 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3. This configuration provides strong single-threaded and multi-threaded performance, as evidenced by its benchmark scores.

In Thief, the CPU’s role is most pronounced at 1080p with lower settings, where the frame rate exceeds 200 FPS. At 1080p Low, the average is 226.6 FPS, and at 1080p Medium, it is 206.1 FPS. These numbers suggest that the CPU can feed the GPU with enough draw calls and game logic updates to sustain very high frame rates. The 3DMark single-thread score of 1286 and multi-thread score of 13929 indicate that the CPU handles both lightly-threaded and heavily-threaded workloads effectively.

The CPU’s 3DMark 16-thread score of 12552 is relevant because Thief, while not a modern multi-core showcase, can utilize multiple threads for physics and AI. The Cinebench R23 multi-core score of 46438 confirms that the 9900X has ample computational headroom. However, at 4K, the CPU’s influence diminishes. The frame rate difference between 4K Low (114.1 FPS) and 4K High (66.3 FPS) is driven more by the GPU’s ability to render the scene than by CPU throughput.

The CPU’s percentile rank of 94 among all tested CPUs means it outperforms 94% of processors in the database. This high percentile, combined with the 12-core count, ensures that Thief is unlikely to be CPU-limited in any scenario except possibly at 1080p with the lowest settings, where the frame rate approaches the CPU’s practical ceiling.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture with the GB205 chip. It has 6144 shading units, 192 texture mapping units, and 80 raster output pipelines. The GPU’s boost clock is 2512 MHz, and its memory operates at 1750 MHz with 28 Gbps effective throughput. The 12 GB GDDR7 memory on a 192-bit bus provides 672.0 GB/s of bandwidth.

In Thief, the GPU’s role is most evident in the scaling between settings at 4K. The jump from Low (114.1 FPS) to Medium (81.6 FPS) to High (66.3 FPS) to Ultra (63.7 FPS) shows a clear performance degradation as the GPU takes on more shading and texture work. The 48 RT cores and 192 tensor cores, while not directly relevant to Thief’s 2014 rendering pipeline, contribute to the GPU’s overall compute capability.

The RTX 5070’s 3DMark Steel Nomad DX12 score of 5077 and Geekbench OpenCL score of 185269 indicate strong raw compute performance. In Thief, this translates to playable frame rates even at 4K Ultra, where the average of 63.7 FPS is just above the 60 FPS target. The GPU’s percentile rank of 83 among all GPUs means it outperforms 83% of the database, which is a solid position for a mid-range-to-high-end card.

The GPU’s nearest rival, the NVIDIA GeForce RTX 3090, has an average score of 41441, which is 0.6% lower than the RTX 5070’s 41687. This proximity in synthetic benchmarks suggests that the RTX 5070 can match or slightly exceed the previous generation’s flagship in certain workloads. In Thief, this equates to the 4K High average of 66.3 FPS, which is a strong result for a game that relies heavily on GPU rasterization.

Settings Recommendations

The measured data provides a clear hierarchy for settings optimization. For players targeting 60 FPS at 4K, the High preset is the best choice, as it delivers 66.3 FPS. The Ultra preset at 4K drops to 63.7 FPS, which is still playable but leaves less headroom for frame time spikes. The Medium preset at 4K offers 81.6 FPS, which is a comfortable margin above 60 FPS and likely provides a more consistent experience.

At 1440p, all settings deliver well above 60 FPS. The Low preset averages 187.6 FPS, Medium 144.5 FPS, High 108.7 FPS, and Ultra 104.7 FPS. For a high-refresh-rate monitor, the Medium preset at 1440p provides a good balance between visual quality and frame rate, as the 144.5 FPS average is sufficient for most displays. The Ultra preset at 1440p still maintains over 100 FPS, making it a viable option for players who prioritize image quality.

At 1080p, every setting exceeds 140 FPS. The Low preset hits 226.6 FPS, Medium 206.1 FPS, High 156.4 FPS, and Ultra 149.1 FPS. For competitive play or maximum responsiveness, the Low preset offers the highest frame rates. However, the High preset at 1080p still provides 156.4 FPS, which is smooth and visually superior. The Ultra preset at 1080p is the most demanding, but its 149.1 FPS average is still excellent.

The data suggests that the optimal experience depends on the display’s resolution and refresh rate. For 4K owners, High settings are recommended to maintain a 60 FPS baseline. For 1440p, Medium or High settings balance quality and speed. For 1080p, High settings offer the best visual fidelity without sacrificing frame rate, as the 156.4 FPS average is more than adequate for most users. The Ultra preset is best reserved for players with high-refresh-rate displays at 1080p or 1440p, as it delivers 149.1 and 104.7 FPS respectively.
