Thief

Thief, a 2014 stealth title, responds predictably but not uniformly to the combination of the Intel Core i9-14900K and the NVIDIA GeForce RTX 5090 D. The measured frame rates across three resolutions and four quality presets reveal a system that is overwhelmingly GPU-bound at higher settings, but begins to show CPU limitations at the lowest preset. This analysis walks through the data to characterize the scaling behavior, component roles, and optimal configuration for this specific pairing.

Resolution Scaling

The frame rate drop from 1920x1080 to 3840x2160 is substantial, but the magnitude of that drop depends heavily on the selected settings preset. At the Ultra preset, the average frame rate falls from 185 FPS at 1080p to 87 FPS at 4K, a reduction of 98 FPS or roughly 53%. This steep decline indicates that the rendering workload at 4K Ultra is taxing the GPU to its limits, leaving little headroom for higher frame rates. The transition from 2560x1440 to 3840x2160 at Ultra shows a similar pattern, with averages dropping from 148 FPS to 87 FPS, a 61 FPS decrease that underscores the pixel-count sensitivity of this configuration.

At the High preset, the scaling is slightly less dramatic but still clearly GPU-bound. The average frame rate moves from 189 FPS at 1080p to 156 FPS at 1440p, then down to 92 FPS at 4K. The 4K High result is only 5 FPS higher than the 4K Ultra result, suggesting that the GPU is approaching a similar performance ceiling regardless of the modest quality reduction between these two presets. The Medium preset tells a more interesting story: at 1080p the average is 208 FPS, at 1440p it is 184 FPS, and at 4K it drops to 120 FPS. The gap between 1440p and 4K here is 64 FPS, which is proportionally larger than the gap between 1080p and 1440p, indicating that the 4K resolution is where the RTX 5090 D begins to struggle with the Medium preset's demands.

The Low preset exhibits the most unusual scaling behavior. At 1080p, the average frame rate is 230 FPS, which is the highest measured result in the entire dataset. At 1440p Low, the average is 203 FPS, and at 4K Low it is 158 FPS. The relative drop from 1080p to 4K is only 72 FPS, or about 31%, which is significantly less than the 53% drop seen at Ultra. This smaller percentage decline at Low settings suggests that the CPU is becoming a more significant factor at lower graphical loads. At 1080p Low, the system is likely hitting a CPU-imposed ceiling, as evidenced by the fact that the 230 FPS average is only 22 FPS higher than the 1080p Low result from a less demanding preset would not be possible if the GPU were the sole bottleneck.

The data reveals a clear inflection point: at 4K, all presets show averages between 87 FPS and 158 FPS, a range of 71 FPS. At 1080p, the range is 185 FPS to 230 FPS, a spread of 45 FPS. The wider range at 4K indicates that the GPU is the dominant limiting component there, while the narrower range at 1080p suggests that other factors, likely the CPU's single-thread performance, are constraining maximum output. For players targeting 4K, the choice of preset has a meaningful impact on frame rate, but even the Low preset cannot reach the 144 FPS threshold that high-refresh-rate 4K displays might demand.

CPU Role

The Intel Core i9-14900K is a 24-core, 32-thread processor based on the Raptor Lake architecture, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. Its benchmark results place it in the 95th percentile among all CPUs, with an average benchmark score of 79,097. In Cinebench R23, it scores 39,399.5 in multi-core and 2,262.5 in single-core, while in Geekbench it achieves 21,697 multi-core and 2,655 single-core. These numbers indicate a processor with exceptional multi-threaded throughput and very strong single-thread performance, which is critical for a game like Thief that was released in 2014 and likely relies on fewer threads.

The CPU's role in Thief is most apparent when examining the Low preset results. At 1080p Low, the average frame rate is 230 FPS, which is only 22 FPS higher than the 1080p Medium result of 208 FPS. This small difference between Low and Medium at 1080p, compared to the 23 FPS difference between Medium and High at the same resolution, suggests that the CPU is nearing its practical limit for this game's engine. The boost clock of 6.00 GHz is among the highest available, and the single-core Cinebench R20 score of 2,935 confirms that this processor can handle legacy workloads efficiently. However, Thief's engine appears to have a frame rate ceiling around 230 FPS in this setup, likely due to game logic or draw call processing that cannot be parallelized across the 32 threads.

The CPU's 36 MB of shared L3 cache and 2 MB per-core L2 cache provide ample memory for game assets, but the 2014 release date means the game was not designed to exploit such large cache hierarchies. The data shows that at 1440p Low, the average frame rate is 203 FPS, which is 27 FPS lower than 1080p Low. This drop indicates that even at Low settings, the GPU is still contributing to the overall performance, and the CPU is not the sole bottleneck until lower resolutions. The closest CPU rival, the Intel Core i9-14900KF, has an average benchmark score of 79,371, which is 0.3% higher than the 14900K, but this difference is negligible for gaming. The AMD Ryzen AI Max+ 395 scores 77,740, which is 1.7% lower, but again, this gap does not translate into meaningful frame rate differences in Thief.

For the measured results, the CPU's impact is most visible in the minimum frame rates recorded at Medium settings. At 1080p Medium, the minimum FPS is 177, while at 1440p Medium it is 156 and at 4K Medium it is 102. These minimums are likely tied to CPU-side frame pacing, as the GPU is capable of higher throughput at lower resolutions. The 177 FPS minimum at 1080p Medium is close to the 185 FPS average at 1080p Ultra, suggesting that the CPU can maintain a consistent frame delivery even when the GPU is less stressed.

GPU Role

The NVIDIA GeForce RTX 5090 D is a 5 nm Blackwell architecture GPU with a massive 92,200 million transistors on a 750 mm² die. It features 32 GB of GDDR7 memory on a 512-bit bus, yielding a bandwidth of 1.79 TB/s. The boost clock is 2407 MHz, and the GPU has 21,760 shading units, 680 TMUs, and 176 ROPs. Its benchmark results place it in the 92nd percentile among all GPUs, with an average benchmark score of 77,712. In 3DMark Steel Nomad DX12, it scores 14,326, and in Geekbench Vulkan it achieves 376,915, which are strong indicators of modern rendering performance.

In Thief, the GPU's role becomes dominant at higher resolutions and settings. At 4K Ultra, the average frame rate is 87 FPS, which is the lowest measured result in the dataset. This is a clear sign that the RTX 5090 D is being pushed hard by the combination of 4K resolution and Ultra quality settings. The 32 GB VRAM is more than sufficient for Thief's textures, even at 4K, so memory capacity is not a limiting factor. The 1.79 TB/s bandwidth ensures that texture streaming is not a bottleneck, but the raw compute requirements of the Ultra preset at 4K still cap the frame rate below 90 FPS.

The GPU's performance scaling with settings is instructive. At 4K, moving from Low to Medium raises the average from 158 FPS to 120 FPS, a 38 FPS drop. Moving from Medium to High lowers it to 92 FPS, another 28 FPS drop, and from High to Ultra it falls to 87 FPS, an additional 5 FPS drop. The diminishing impact of the High-to-Ultra transition suggests that the Ultra preset adds effects that are particularly expensive at 4K, but the GPU is already near its limit at High. At 1440p, the pattern is similar but with higher absolute numbers: Low averages 203 FPS, Medium 184 FPS, High 156 FPS, and Ultra 148 FPS. The 8 FPS difference between High and Ultra at 1440p is larger than the 5 FPS difference at 4K, indicating that the GPU has more headroom at lower resolutions.

The RTX 5090 D's closest rivals in the benchmark database show interesting deltas. The AMD Radeon RX 6850M XT has an average score of 78,940, which is 1.6% higher, while the NVIDIA Tesla P100 PCIe 16 GB scores 79,605, 2.4% higher. These are not direct gaming competitors, but the data shows that the RTX 5090 D is slightly below these in raw compute benchmarks. However, in Thief, the GPU's actual gaming performance is what matters, and the measured FPS at all resolutions and presets exceeds 87 FPS, which is playable for most users.

The GPU's 104.8 TFLOPS FP32 performance is substantial, but Thief's 2014 engine likely does not utilize modern features like ray tracing or DLSS, so the GPU is running in a more traditional rendering mode. The 2407 MHz boost clock is high, but the game's draw calls and shader complexity are from an era before such powerful GPUs, so the RTX 5090 D is not being fully utilized at lower settings. At 1080p Low, the 230 FPS average is likely close to the CPU's limit, as the GPU is capable of much higher frame rates in less CPU-constrained scenarios.

FAQ

Q: What is the difference in average FPS between the High and Ultra presets at 1080p?

A: At 1920x1080, the High preset averages 189 FPS, while the Ultra preset averages 185 FPS, a difference of only 4 FPS. This suggests that the Ultra preset's additional visual effects have minimal performance impact at this resolution.

How This Combo Ranks

The combination of the Intel Core i9-14900K and the NVIDIA GeForce RTX 5090 D achieves a rank of 9 out of 2,851 tested combos in Thief, placing it in the top 0.3% of all configurations. This rank reflects the high-end nature of both components, but it is notable that the combo does not reach the top spot, suggesting that other pairings may yield even higher frame rates in this specific game. The rank of 9 indicates that there are only 8 other combinations that outperform this setup in Thief, which is a small margin given the database contains over 2,800 entries.

The combo's performance is consistent with the individual component rankings: the CPU is in the 95th percentile and the GPU is in the 92nd percentile, so a combined rank of 9 is slightly better than either component's percentile would suggest. This could be due to the CPU's high single-thread performance, which is critical for Thief's older engine, and the GPU's ample bandwidth for texture-heavy scenes. The nearest rival CPUs, such as the Core i9-14900KF with a 0.3% higher average score, are unlikely to produce significantly different results in Thief, as the game does not stress multi-core performance to the extent that Cinebench does.

The rank of 9 also suggests that while this is an exceptionally fast configuration, there is headroom for improvement with other components. For example, a CPU with even higher single-thread performance or a GPU with better driver optimization for legacy titles could potentially push the combo higher. However, for most users, being in the top 0.3% of all tested combinations is more than sufficient for a smooth experience in Thief, even at 4K Ultra where the average frame rate is 87 FPS.

Settings Recommendations

Based on the measured data, the optimal settings preset depends heavily on the target resolution and desired frame rate. For 4K gaming, the High preset at 92 FPS average is the best balance between visual quality and performance, as the Ultra preset only delivers 87 FPS, a marginal 5 FPS improvement in quality is not worth the 5 FPS loss. The Medium preset at 120 FPS is also a strong choice for 4K if higher frame rates are preferred, as it offers a 28 FPS advantage over High while still maintaining reasonable visual fidelity.

At 1440p, the High preset at 156 FPS is the recommended choice for most users, as it approaches the 165 Hz refresh rate common on many 1440p monitors. The Ultra preset at 148 FPS is close behind, and the 8 FPS difference may be acceptable for those who prioritize maximum quality. The Medium preset at 184 FPS is better suited for competitive play or high-refresh-rate displays, but the visual downgrade from High is noticeable.

For 1080p, the High preset at 189 FPS is the sweet spot, as the Ultra preset only adds 4 FPS in quality for a 4 FPS performance hit, making High the more efficient choice. The Medium preset at 208 FPS is ideal for 240 Hz displays, but the Low preset at 230 FPS is only 22 FPS higher, so the CPU limit is near and the visual quality loss is significant. In all cases, the data shows that the Low preset is rarely worth using, as the Medium preset provides substantially better visuals for a modest FPS reduction at every resolution.

Measured FPS Breakdown

At 1920x1080, the measured averages are as follows: Low averages 230 FPS, Medium averages 208 FPS with a minimum of 177 FPS and a maximum of 240 FPS, High averages 189 FPS, and Ultra averages 185 FPS. The Medium preset's minimum of 177 FPS is notably lower than its average, indicating some frame pacing variance, but the maximum of 240 FPS suggests the GPU can burst higher when the scene is less demanding. The spread between Low and Ultra is 45 FPS, which is the smallest across all resolutions, reinforcing the CPU-bound nature at 1080p.

At 2560x1440, the averages are: Low at 203 FPS, Medium at 184 FPS with a minimum of 156 FPS and a maximum of 211 FPS, High at 156 FPS, and Ultra at 148 FPS. The Medium preset's minimum of 156 FPS is exactly equal to the High preset's average, indicating that the High preset may experience occasional drops below that figure, even though no minimum was recorded. The gap between Low and Ultra is 55 FPS, wider than at 1080p, showing the GPU's increasing role.

At 3840x2160, the averages are: Low at 158 FPS, Medium at 120 FPS with a minimum of 102 FPS and a maximum of 138 FPS, High at 92 FPS, and Ultra at 87 FPS. The Medium preset's maximum of 138 FPS is higher than the High preset's average of 92 FPS, demonstrating that the GPU can achieve higher frame rates in less demanding scenes even at 4K. The gap between Low and Ultra is 71 FPS, the largest of any resolution, confirming that 4K is where the GPU is most stressed. The Ultra preset's 87 FPS average is the only result below 90 FPS in the entire dataset, making it the most demanding configuration tested.
