Thief

Thief, a 2014 stealth title, is an older game, but the benchmark data for this Intel Core i5-14600KF and NVIDIA GeForce RTX 5090 D combination reveals how modern high-end hardware handles legacy code. The results show a system that is massively overqualified for the task, with performance bottlenecks shifting based on resolution and settings. This analysis breaks down the measured FPS data to understand the scaling, ranking, and component roles in this specific configuration.

Resolution Scaling

The most striking observation from the measured data is the relatively flat performance scaling across resolutions, which is unusual for modern games. At High settings, the average FPS only drops from 171 at 1920x1080 to 151 at 2560x1440, and then to 92 at 3840x2160. The drop from 1440p to 4K is significant, representing a roughly 39% reduction in frame rate, but the 1080p to 1440p transition is minimal. This pattern indicates that at lower resolutions, the game is heavily CPU-bound, meaning the processor cannot feed frames fast enough to utilize the GPU's full potential.

The data strongly suggests that the CPU is the limiting factor at 1080p and 1440p. The RTX 5090 D is capable of far more than 171 FPS at 1080p in a game like this, but the i5-14600KF, while powerful, is hitting its limits with the game's engine. This is a classic scenario with older titles that were not designed for multi-threaded processing on modern scales. As we move to 4K, the GPU workload increases substantially, and the frame rate drops to 92 FPS at High settings. This indicates the load is finally shifting to the graphics card, but even at 4K, the 92 FPS result is likely still partially limited by the CPU's single-thread performance in certain scenes.

Looking at the Low settings across resolutions provides further insight. At 1080p Low, the system hits 209 FPS. At 1440p Low, it only drops to 184 FPS, and at 4K Low, it still manages 154 FPS. The relatively small delta between 1080p and 1440p Low (only 25 FPS) again points to a CPU bottleneck. The game simply cannot push more frames. However, the jump from 1440p to 4K Low shows a more substantial 30 FPS drop, confirming that 4K is where the GPU starts to become a more significant factor.

The scaling from Low to Ultra at each resolution is also telling. At 1080p, the difference between Low (209 FPS) and Ultra (168 FPS) is just 41 FPS. At 1440p, the spread is even smaller, from 184 FPS on Low to 148 FPS on Ultra. At 4K, the spread widens significantly, from 154 FPS on Low to 87 FPS on Ultra. This widening gap at higher resolutions confirms that the GPU becomes the primary bottleneck as pixel count and graphical complexity increase. The CPU has more headroom to work with, allowing the GPU's performance characteristics to become the deciding factor.

How This Combo Ranks

This specific combination of the Intel Core i5-14600KF and NVIDIA GeForce RTX 5090 D ranks 58th out of 2851 tested combos in Thief. This places it in the top 2% of all configurations tested, which is an exceptional result. The high ranking is primarily driven by the RTX 5090 D's immense raw power, which ensures that even in a CPU-limited scenario, the frame rates are extremely high. The processor's strong single-core performance, evidenced by its Cinebench R23 single-core score of 4594, also plays a crucial role in maintaining high FPS in this older title.

While a rank of 58 is outstanding, it is important to note that the i5-14600KF is not the absolute best CPU for this game, nor is the RTX 5090 D the absolute best GPU in the database's testing. The CPU's average benchmark score of 49394 puts it in the 90th percentile of all CPUs, and its nearest rival, the AMD Ryzen 9 7900, scores nearly identically at 49228, a delta of just 0.3%. This suggests that many high-end CPUs would perform similarly in Thief. The GPU's average score of 77712 places it in the 92nd percentile, with rivals like the AMD Radeon RX 6850M XT (score 78940, delta -1.6%) and the NVIDIA Tesla P100 PCIe 16 GB (score 79605, delta -2.4%) outperforming it in synthetic benchmarks. However, in actual game testing, the RTX 5090 D's driver optimization and architecture prove highly effective.

The rank of 58 out of 2851 confirms the fact that this is a top-tier gaming combo. The system is capable of delivering an excellent experience at any resolution, and the data shows that the primary limitation is the game's engine, not the hardware. For a 2014 title, achieving a rank this high indicates the pair is more than sufficient for maxing out the game and likely has significant headroom for more modern, demanding titles.

GPU Role

The NVIDIA GeForce RTX 5090 D is the dominant component in this pairing. Its specifications are staggering: 32 GB of GDDR7 memory on a 512-bit bus, yielding a bandwidth of 1.79 TB/s. This massive memory pool is far more than Thief requires, but it ensures that memory capacity is never a limiting factor. The GPU's 21760 shading units and boost clock of 2407 MHz provide the raw compute power needed to push high frame rates, especially at 4K.

In the measured data, the GPU's role becomes increasingly important as resolution and settings increase. At 4K Ultra, the system achieves 87 FPS, which is a demanding scenario that starts to stress the GPU. The jump from 4K High (92 FPS) to 4K Ultra (87 FPS) is small, but it shows that the GPU is beginning to feel the load. The data for 4K Medium shows an average of 120 FPS with a minimum of 102 FPS and a maximum of 138 FPS, indicating a stable performance window that is primarily GPU-limited.

The GPU's synthetic benchmark scores, such as its 3DMark Steel Nomad DX12 score of 14326 and its Passmark G3D score of 44065, confirm its high-end positioning. Its nearest rivals in synthetic tests are mobile GPUs like the AMD Radeon RX 6850M XT, which it outperforms in this game despite having a lower average synthetic score. This suggests that the RTX 5090 D's architecture, Blackwell 2.0, is particularly well-suited for Thief's rendering methods. The 92nd percentile ranking versus all GPUs underscores that this is a flagship-level part, and its performance in this game is excellent, even if the CPU holds it back at lower resolutions.

The GPU's high pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are more than enough to handle the game's maximum detail settings. At no point in the measured data does the GPU appear to be a weakness. Instead, it provides a ceiling that the CPU cannot always reach. The 32 GB of VRAM is also a non-issue, as Thief will never come close to using it, leaving plenty of headroom for texture mods or running the game at extremely high resolutions with supersampling.

FAQ

Q: At what resolution does this combo become GPU-bound instead of CPU-bound?

A: Based on the FPS data, the system is heavily CPU-bound at 1080p and 1440p. The transition to being GPU-bound becomes apparent at 4K, where the average FPS drops more significantly between settings (e.g., 154 FPS at Low to 87 FPS at Ultra), indicating the graphics card is now the primary limiting factor.

Q: What is the best resolution to play Thief with this hardware for a high refresh rate experience?

A: At 2560x1440, the system achieves an average of 167 FPS on Medium settings and 151 FPS on High, which is excellent for a high refresh rate monitor. At 1920x1080, it can push over 200 FPS on Low (209 FPS) and 171 FPS on High, but the CPU bottleneck limits the gains.

Q: Is the RTX 5090 D's 32 GB of VRAM necessary for Thief?

A: No. Thief is a 2014 title and its texture requirements are modest. The 32 GB of GDDR7 memory is far more than the game needs. However, this headroom ensures there are no memory-related stutters or texture pop-in, and provides massive future-proofing for other games.

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

A: This combination ranks 58th out of 2851 tested combos in Thief. This places it in the top 2% of all configurations, confirming it as a high-end performer that is more than capable of maxing out this game.

Q: What are the minimum FPS figures at 4K Medium settings?

A: At 3840x2160 with Medium settings, the combo produces an average of 120 FPS with a minimum of 102 FPS and a maximum of 138 FPS. This shows a stable performance floor that remains well above 100 FPS.

Q: Is the Intel Core i5-14600KF holding back the RTX 5090 D in this game?

A: Yes, clearly. The small FPS gains from 1080p to 1440p at the same settings (e.g., High goes from 171 to 151 FPS) indicate a CPU bottleneck. The CPU's 14 cores and 20 threads are not fully utilized by Thief, and its strong single-core performance, while good, cannot feed the GPU fast enough at lower resolutions.

Settings Recommendations

The benchmark data reveals that this system has more than enough power to run Thief at maximum settings at any resolution. The optimal choice depends on the user's display and preference for frame rate over visual fidelity. For a 4K display, the High preset is the best balance, delivering an average of 92 FPS. Moving to Ultra only yields a 5 FPS reduction to 87 FPS, but the visual improvement may be negligible to some. The Medium preset at 4K offers a significant boost to 120 FPS, which is preferable if a higher refresh rate is the priority.

At 2560x1440, the Ultra preset is the clear recommendation. The average of 148 FPS is well above the 144 Hz threshold, and the system has enough headroom to handle the maximum visual details without dropping below playable levels. The High preset at 151 FPS is nearly identical, so there is little reason not to use Ultra. For those with a 240 Hz monitor, dropping to Medium (167 FPS) or Low (184 FPS) could be considered, but the visual sacrifice is substantial for a modest FPS gain.

At 1920x1080, the system is heavily CPU-bound, and the FPS differences between settings are minimal. The Ultra preset still delivers an excellent 168 FPS average, making it the best choice for the highest visual quality without a meaningful performance penalty. The High preset is nearly identical at 171 FPS. Using Low or Medium settings would only provide a marginal FPS increase (up to 209 FPS on Low) at the cost of drastically reduced visual quality. In this scenario, it is always best to use the Ultra preset, as the CPU is the limiting factor, not the GPU.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor based on the Raptor Lake architecture. Its base clock of 3.50 GHz and boost clock of 5.30 GHz provide excellent single-threaded performance, which is critical for older games like Thief that often rely on one or two primary threads. The CPU's Cinebench R23 single-core score of 4594 highlights its strength in this area. However, the game's engine is not designed to utilize the full multi-threading capabilities of modern processors, which is why the CPU becomes a bottleneck.

The data shows that the CPU is the limiting factor at 1080p and 1440p. For example, at 1080p, the average FPS only drops from 209 on Low to 168 on Ultra, a 41 FPS difference. This relatively small spread indicates that the CPU is working hard to maintain these high frame rates, and the GPU has little impact on the final result. The same pattern is visible at 1440p, where the difference between Low (184 FPS) and Ultra (148 FPS) is just 36 FPS. The CPU's inability to scale beyond these numbers is the primary constraint.

Its multi-core performance, with a Cinebench R23 multi-core score of 32544 and a Passmark multithread score of 38697, is not relevant for this specific game. While the 14 cores and 20 threads are excellent for modern, heavily-threaded titles, Thief does not benefit from them. The CPU's 24 MB of shared L3 cache is more than sufficient for the game's data needs, but the processing bottleneck remains. The CPU's 90th percentile ranking versus all CPUs shows it is a top-tier part, but in this context, it is the weaker link in the chain, preventing the RTX 5090 D from achieving even higher frame rates at lower resolutions.
