Thief

The Intel Core i5-14600K paired with the NVIDIA GeForce RTX 5070 Ti delivers a performance profile in Thief that is heavily influenced by the game’s age and the sheer headroom of both components. The measured frame rates across the three tested resolutions reveal a system that is rarely stressed, but the scaling patterns provide clear insight into where the bottleneck shifts. At 1080p, the average frame rates range from 171.3 FPS at High settings to 210.1 FPS at Low, indicating that the CPU is doing the heavy lifting but is far from saturated. Moving to 1440p, the frame rates remain exceptionally high, with the Ultra preset still delivering 115.8 FPS. At 4K, the GPU begins to assert its dominance, with the Ultra preset dropping to 69.5 FPS and the High preset settling at 72.4 FPS. This scaling from 1080p to 4K—a drop of roughly 59% for Ultra settings—shows that while the RTX 5070 Ti is capable, the game’s engine and the CPU’s rapid single-thread performance keep the system from ever feeling constrained at lower resolutions.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 is telling. At 1080p with Low settings, the system produces 210.1 FPS, which drops to 187.2 FPS at 1440p and then to 126.1 FPS at 4K. This pattern shows a 40% reduction from 1080p to 4K, a smaller delta than one might expect from a GPU-heavy title, suggesting that the CPU’s 5.30 GHz boost clock is masking some of the GPU’s workload at lower resolutions. The High preset tells a similar story: 171.3 FPS at 1080p, 126.3 FPS at 1440p, and 72.4 FPS at 4K. Here, the 4K figure is less than half of the 1080p result, which is a clear sign that the GPU is becoming the limiting factor. The RTX 5070 Ti’s 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are sufficient for 4K, but the raw pixel throughput of 235.4 GPixel/s is being taxed by the higher resolution. Notably, the gap between Medium and High settings narrows as resolution increases: at 1080p, the difference is 20.2 FPS, but at 4K, it shrinks to 25.4 FPS, indicating that the GPU’s shading units are the primary constraint at 4K rather than memory bandwidth.

Settings Recommendations

For the best experience per the measured rows, the data points to the High preset as the sweet spot. At 1440p, High yields 126.3 FPS, which is only 11.1 FPS lower than Medium at 163.2 FPS, but the visual quality jump is substantial. At 4K, High produces 72.4 FPS, which is playable for a stealth title, while Ultra drops to 69.5 FPS—a negligible 2.9 FPS improvement over High, making Ultra a poor trade-off for the extra GPU load. The Low preset at 4K hits 126.1 FPS, but it leaves performance on the table; the jump to Medium at 97.8 FPS is more reasonable, yet High’s 72.4 FPS is still above the 60 FPS threshold. For users with high-refresh displays, 1080p Medium at 191.5 FPS is the most balanced choice, as it stays above 144 Hz while providing better fidelity than Low. The Ultra preset at 1080p (171.7 FPS) is only 19.8 FPS slower than Medium, which is a minor cost for maximum settings. At 1440p, Ultra at 115.8 FPS is still fluid, but High at 126.3 FPS offers a better margin for 120 Hz displays. The recommendation is to prioritize High across all resolutions, as it consistently sits in the upper tier of performance without the diminishing returns seen in Ultra.

GPU Role

The NVIDIA GeForce RTX 5070 Ti’s specifications directly explain its behavior in Thief. With a boost clock of 2452 MHz and 8960 shading units, the GPU is capable of immense throughput, but the game’s 2014 engine does not fully utilize the Blackwell 2.0 architecture’s features. The 16 GB of GDDR7 memory is never a constraint; even at 4K Ultra, the frame rate drops are due to pixel fill rate and shader work, not memory capacity. The GPU’s 43.94 TFLOPS of FP32 performance is overkill for a title of this era, which is why the 4K Low preset still achieves 126.1 FPS. The memory clock of 1750 MHz (28 Gbps effective) provides 896.0 GB/s of bandwidth, which is ample for the game’s texture streaming at any resolution. The GPU’s percentileVsAllGpus of 87 places it in the upper echelon, and its nearest rival, the NVIDIA GeForce RTX 4080, has an identical average benchmark score with a deltaPct of 0. This parity is reflected in the game’s measured results, where the RTX 5070 Ti’s performance is smooth but not revelatory—the game simply does not push the GPU hard enough to differentiate it from lower-tier cards. The pixel rate of 235.4 GPixel/s is the limiting factor at 4K, as evidenced by the 69.5 FPS Ultra result, which aligns with the GPU’s 96 ROPs doing the heavy lifting.

How This Combo Ranks

In the database of tested combos for Thief, this pairing of the Intel Core i5-14600K and NVIDIA GeForce RTX 5070 Ti ranks 71st out of 1642 combinations. This places it in the top 4.3% of all tested systems, which is a strong showing given the game’s age. The rank reflects that while the GPU is top-tier, the CPU’s architecture is not the absolute fastest for this workload; the i5-14600K’s 14 cores and 20 threads are more than sufficient, but its cinebench_r23 multicore score of 32881 and single-core score of 4642 are mid-pack among modern CPUs. The combo’s position is buoyed by the GPU’s high average benchmark score of 52086, which is 87th percentile among all GPUs. The CPU’s avgBenchmarkScore of 49166 is in the 93rd percentile, but its nearest rivals—the AMD Ryzen 9 5950X (0.2% faster) and the Intel Core i5-14600KF (0.4% slower)—show that the CPU is not a differentiator in this game. The rank of 71 suggests that there are 70 combos with faster CPUs or GPUs, but for Thief, the frame rates are so high that the ranking is more about theoretical headroom than practical playability. The data shows that this combo is overkill for the game, but it does not waste its potential—the 4K Ultra result of 69.5 FPS is the only sub-70 figure, and it is still playable.

CPU Role

The Intel Core i5-14600K’s performance in Thief is defined by its single-thread capabilities. The CPU’s boost clock of 5.30 GHz is the key driver, as the game’s engine relies heavily on a few cores. The cinebench_r15 single-core score of 467 and geekbench_singlecore score of 2803 indicate strong per-core performance, which is why the 1080p Low preset hits 210.1 FPS. The CPU’s 14 cores (6 performance and 8 efficiency) are not fully utilized, but the 20 threads ensure that background tasks do not interfere. The L3 cache of 24 MB shared is adequate, and the 10 nm process node keeps latency low. The CPU’s percentileVsAllCpus of 93 means it is faster than 93% of all tested CPUs, but its nearest rivals show it is not class-leading. The AMD Ryzen 9 5950X has a deltaPct of 0.2% faster, which is negligible, and the Intel Core i5-14600KF is 0.4% slower, confirming that the CPU is a known quantity. In Thief, the CPU’s role is to feed the GPU without bottlenecking, and the data shows it does so effectively: at 1080p, the frame rates are CPU-limited, but the jump from High (171.3 FPS) to Low (210.1 FPS) is only 38.8 FPS, suggesting that even the CPU is not the sole limiter. The CPU’s passmark_single_thread score of 4270 and passmark_multithread score of 38682 show that it has ample headroom, but the game simply does not demand more.

Measured FPS Breakdown

The exact measured frame rates reveal a consistent hierarchy across settings and resolutions. At 1920x1080, the average FPS starts at 210.1 for Low, drops to 191.5 for Medium, then 171.3 for High, and finally 171.7 for Ultra. The near-equal High and Ultra results (a 0.4 FPS difference) indicate that Ultra is not taxing the GPU further at this resolution—the CPU is the limit. At 2560x1440, the spread widens: Low produces 187.2 FPS, Medium 163.2 FPS, High 126.3 FPS, and Ultra 115.8 FPS. The gap between Medium and High is 36.9 FPS, showing that the GPU is beginning to work harder. At 3840x2160, the results are 126.1 FPS for Low, 97.8 FPS for Medium, 72.4 FPS for High, and 69.5 FPS for Ultra. The drop from Low to Medium at 4K is 28.3 FPS, and from Medium to High is 25.4 FPS, while High to Ultra is only 2.9 FPS. This final small delta confirms that Ultra’s extra settings are not worth the performance cost. The data also shows that the 1440p High result (126.3 FPS) is nearly identical to the 4K Low result (126.1 FPS), which is an interesting crossover point—it suggests that users can achieve the same frame rate by either lowering resolution or lowering settings. The 1080p Ultra result of 171.7 FPS is slightly higher than the 1080p High result of 171.3 FPS, which is a statistical anomaly that reinforces the CPU-bound nature at that resolution. Across all 12 measured rows, the system never dips below 69.5 FPS, making it more than capable of delivering a smooth experience in Thief at any preset.
