Thief

The Intel Core i7-14700K paired with the NVIDIA GeForce RTX 5090 delivers a high-refresh-rate experience in Thief, but the data reveals a clear pattern: this 2014 stealth classic becomes increasingly GPU-bound as resolution climbs. At 1080p, the combo posts a 221.5 FPS average on Low settings, but that figure drops to 84.8 FPS at 4K on High. The scaling suggests that while the RTX 5090 is the dominant force at higher resolutions, the i7-14700K’s 20 cores and 28 threads are more than sufficient to feed it at lower settings, where the frame rates approach the practical limits of the game’s engine.

Resolution Scaling

The measured FPS data shows a steady, predictable decline as resolution increases, but the rate of that decline varies by settings preset. At Low settings, the drop from 1080p to 1440p is 221.5 FPS to 195.8 FPS, a reduction of roughly 11.6%. Moving from 1440p to 4K at Low yields 150.3 FPS, another 23.2% decrease. This indicates that even at Low settings, the GPU is still the primary bottleneck at 4K, though the absolute numbers remain exceptionally high.

The High preset tells a similar story: 177.6 FPS at 1080p, 145.5 FPS at 1440p, and 84.8 FPS at 4K. The 4K figure is less than half of the 1080p result, which is a steeper drop than the Low preset experienced. This suggests that the High preset introduces effects that are disproportionately expensive at higher pixel counts, likely pushing the RTX 5090’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth harder. The Ultra preset follows the same curve: 179.4 FPS at 1080p, 143 FPS at 1440p, and 85.5 FPS at 4K.

The most revealing jump is between 1440p and 4K on the High and Ultra presets. At 1440p, High delivers 145.5 FPS, but 4K High drops to 84.8 FPS — a 41.7% loss. This is a classic sign of the GPU hitting a memory bandwidth or fill-rate wall, as the RTX 5090’s 423.6 GPixel/s pixel rate and 1,636.8 GTexel/s texture rate are being saturated by the roughly 2.25x increase in pixel count from 1440p to 4K. The i7-14700K, with its 33 MB of shared L3 cache and 5.60 GHz boost clock, is not the limiting factor here; benchmark results indicate the CPU can sustain well over 200 FPS at 1080p, so the scaling curve is almost entirely dictated by the GPU.

FAQ

Q: Does the RTX 5090 bottleneck the i7-14700K at 1080p in this game?

A: No. At 1080p Low, the combo reaches 221.5 FPS, and at 1080p Ultra it still manages 179.4 FPS. These figures are high enough that the i7-14700K’s single-core performance (6,287 in Cinebench R23) keeps pace with the GPU’s output, indicating a balanced pairing at this resolution.

*Q: What is the best resolution to play Thief with this hardware?*

A: For a 144Hz or 165Hz monitor, 1440p is the sweet spot. The High preset delivers 145.5 FPS, and even Ultra manages 143 FPS, both of which are well above refresh-rate thresholds for smooth gameplay. At 4K, you’ll need to stick with Medium (116.4 FPS) to stay above 100 FPS, as High and Ultra drop to the mid-80s.

*Q: How does the RTX 5090’s 32 GB VRAM affect Thief performance?*

A: The 32 GB GDDR7 frame buffer is far more than Thief needs, even at 4K Ultra. The memory bandwidth of 1.79 TB/s is the more relevant factor, as the performance drop from 1440p to 4K suggests the GPU is bandwidth-limited rather than capacity-limited. The game’s 2014 release date means it likely uses only a fraction of the VRAM available.

Q: Is the i7-14700K a good match for the RTX 5090 in this specific title?

A: Yes. The CPU’s 96th percentile ranking among all CPUs and its multi-core score of 44,534 in Cinebench R23 indicate it has ample headroom. The measured FPS at 1080p Low (221.5 FPS) is likely near the engine’s ceiling, so the CPU is not holding back the GPU at any tested setting.

Q: What is the difference between the High and Ultra presets at 4K?

A: Almost none in practice. High averages 84.8 FPS, while Ultra averages 85.5 FPS — a 0.8% difference that is within run-to-run variance. This suggests the Ultra preset adds minimal visual fidelity for the same performance cost, making High the more efficient choice at 4K.

Q: How does this combo rank compared to other tested configurations?

A: This specific pairing ranks 9th out of 1,642 tested combos in Thief. That places it in the top 0.5% of all configurations, though the game’s age and engine limits mean the absolute FPS numbers are more about raw GPU power than CPU tuning.

GPU Role

The NVIDIA GeForce RTX 5090 is the clear performance driver in this pairing. Its 104.8 TFLOPS FP32 compute and 21,760 shading units provide the raw throughput needed to push Thief past 200 FPS at 1080p, but the more interesting data comes from its memory subsystem. The GDDR7 memory runs at 1750 MHz with a 28 Gbps effective rate, feeding a 512-bit bus for a total of 1.79 TB/s. This bandwidth is critical at 4K, where the pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are heavily utilized.

The GPU’s boost clock of 2407 MHz and base clock of 2017 MHz are relatively modest for a flagship, but the Blackwell 2.0 architecture’s efficiency is evident in the benchmark scores. The 3DMark Steel Nomad DX12 score of 14,411 and Passmark G3D score of 39,650 place the RTX 5090 in the 94th percentile of all GPUs. In Thief, the GPU’s role is most apparent when comparing Low to Medium settings at 4K: the jump from 150.3 FPS to 116.4 FPS is a 22.6% drop, which is a larger relative loss than the 1080p equivalent (221.5 to 197.8 FPS, an 10.7% drop). This indicates that the Medium preset’s additional lighting and shadow effects are more computationally expensive at higher resolutions, confirming the GPU is the primary constraint.

The RTX 5090’s 575 W TDP and 950 W suggested PSU are worth noting for system builders, but in terms of Thief performance, the card’s 32 GB GDDR7 memory is never a limiting factor. The game was released in 2014, so its texture budgets are likely small, meaning the GPU’s bandwidth and compute are what matter, not its capacity.

How This Combo Ranks

In the benchmark database, the Intel Core i7-14700K + NVIDIA GeForce RTX 5090 combination ranks 9th out of 1,642 tested combos in Thief. This top-10 placement is expected given the hardware’s pedigree, but the data shows that the gap between this combo and the 8th or 10th place is likely minimal, as the game’s engine caps out around 220 FPS regardless of CPU or GPU muscle. The combo’s 1080p Low score of 221.5 FPS is probably near the engine’s hard limit, meaning that lower-ranked combos with slower GPUs may achieve identical or near-identical results at that resolution.

At 4K, the rank becomes more meaningful. The 84.8 FPS High result and 85.5 FPS Ultra result are high enough that only a handful of other combos — likely those with the RTX 5090 D or similar top-tier GPUs — could match or beat them. The CPU’s nearest rivals, including the Intel Core i7-14700KF and AMD Ryzen 9 9950X, have similar average benchmark scores (70,104 and 70,420 respectively), which means swapping the CPU would not materially change the Thief FPS. The GPU’s nearest rivals, such as the RTX 5090 D, have nearly identical average scores (84,241 vs. 84,306), reinforcing that this combo’s rank is primarily a function of the GPU, not the CPU.

Settings Recommendations

For a 60 Hz 4K display, the Medium preset is the optimal choice. It delivers 116.4 FPS at 3840x2160, which is well above 60 FPS and leaves headroom for frame drops. High and Ultra both sit in the mid-80s, which is playable but not ideal for a 120 Hz or 144 Hz 4K panel. If you have a 144 Hz 4K monitor, you’ll need to step down to Low (150.3 FPS) to fully utilize the refresh rate, but the visual compromise may not be worth it for a game like Thief, where atmosphere matters.

At 1440p, the High preset (145.5 FPS) is the best balance of quality and speed. Ultra (143 FPS) is nearly identical, so choose based on personal preference for minor visual tweaks. Low (195.8 FPS) and Medium (175.4 FPS) are unnecessary unless you’re chasing 200+ FPS on a 240 Hz monitor. At 1080p, all presets are viable, with Ultra (179.4 FPS) and High (177.6 FPS) being the most sensible picks for high-refresh-rate gaming. The data shows that the difference between High and Ultra is negligible across all resolutions, so High is the recommended preset for consistency and efficiency.

Measured FPS Breakdown

3840x2160 (4K):

• Low: 150.3 FPS average
• Medium: 116.4 FPS average
• High: 84.8 FPS average
• Ultra: 85.5 FPS average

2560x1440 (1440p):

• Low: 195.8 FPS average
• Medium: 175.4 FPS average
• High: 145.5 FPS average
• Ultra: 143 FPS average

1920x1080 (1080p):

• Low: 221.5 FPS average
• Medium: 197.8 FPS average
• High: 177.6 FPS average
• Ultra: 179.4 FPS average

The data reveals two notable anomalies. First, at 1080p, Ultra (179.4 FPS) outperforms High (177.6 FPS) by 1.8 FPS, which is within margin of error but suggests the Ultra preset might use different draw calls or LOD distances that interact favorably with the i7-14700K’s cache hierarchy. Second, at 4K, Ultra (85.5 FPS) is faster than High (84.8 FPS) by 0.7 FPS, again a negligible difference. These small variances indicate that the High and Ultra presets are nearly identical in cost, and the measured differences are likely run-to-run noise rather than systematic. The larger trend is consistent: each step from Low to Medium costs roughly 20-25% of FPS at 4K, while the step from Medium to High costs about 27%, confirming that the higher presets are exponentially more demanding at higher resolutions.
