Thief

The Intel Core i5-14400F and Intel Arc B580 combination delivers playable performance in Thief, but the experience is heavily dependent on resolution and settings. At 1920x1080, this system is exceptionally capable, clearing 60 FPS at every preset, while 2560x1440 remains comfortable at Medium settings. The data shows a sharp drop-off at 3840x2160, where only the Low preset manages to stay above the 60 FPS threshold.

Similar Performance Alternatives

The CPU and GPU sit within a narrow performance band compared to their nearest rivals, meaning the behavior seen in Thief is representative of a specific performance tier rather than an outlier.

For the Intel Core i5-14400F, the benchmark data places it in the 83rd percentile of all CPUs. Its nearest rival, the AMD Ryzen 7 PRO 8840U, has an average score only 0.1% higher, indicating virtually identical computational throughput in synthetic tests. The Intel Core i9-11900 trails by a mere 0.2%, while the AMD Ryzen 7 6800HS is 0.2% slower, and the Intel Core i7-12800H is 0.5% behind. In practical terms for Thief, a game released in 2014 that is not heavily threaded, any of these CPUs would deliver nearly indistinguishable frame rates, as the bottleneck at most settings will be the graphics card, not the processor.

On the graphics side, the Intel Arc B580 ranks in the 68th percentile of all GPUs. Its closest competitor, the AMD Radeon RX 580 2048SP, scores 0.2% higher, making them effectively equal. The NVIDIA GeForce RTX 2080 is 0.6% behind, while the NVIDIA GeForce RTX 3080 is 0.7% ahead, and the NVIDIA P106-100 leads by 1%. These delta percentages are all under 1%, signaling that the Arc B580's raw performance in this game is tightly grouped with these other cards. Consequently, a system swapping the Arc B580 for any of these rivals would see only a handful of frames difference at each resolution and preset in Thief.

CPU and GPU Roles

The performance scaling across resolutions and presets reveals that the Intel Arc B580 is the dominant factor in this configuration for Thief. The CPU's role is secondary, providing sufficient headroom but not being the limiting component.

Evidence for this comes from the frame rate progression as resolution increases. At 1920x1080 with Ultra settings, the system achieves 83.2 FPS. Moving to 2560x1440 at Ultra drops the average to 58.6 FPS, a reduction of roughly 30%. At 3840x2160 Ultra, the average falls to 30.9 FPS, which is about 47% lower than the 1440p figure and 63% lower than 1080p. This steep decline with resolution is characteristic of a GPU-bound workload; the pixel fill rate and memory bandwidth demands of higher resolutions are taxing the Arc B580's 456.0 GB/s bandwidth and 13.67 TFLOPS compute capability.

The preset scaling further confirms this. At 1920x1080, the difference between Low (148.8 FPS) and Ultra (83.2 FPS) is 65.6 FPS, which is substantial but still playable. At 3840x2160, the gap between Low (60.4 FPS) and Ultra (30.9 FPS) is 29.5 FPS, but the absolute numbers are much lower. Since the CPU workload for Thief does not increase proportionally with resolution, the consistent frame drops at higher resolutions are almost entirely attributable to the GPU's rendering load. The Intel Core i5-14400F, with 10 cores and 16 threads, is more than adequate for the game's logic and draw calls, as evidenced by the high frame rates at 1080p, where the CPU would have the most influence relative to the GPU.

Measured FPS Breakdown

The measured data provides a clear picture of performance at each resolution and preset. All figures are average FPS; no minimum or maximum values were recorded.

At 1920x1080, the system is overwhelmingly fast. The Low preset produces 148.8 FPS, which is more than double the playable threshold. Medium increases visual quality while still delivering 115.6 FPS. High settings yield 85.2 FPS, and even the demanding Ultra preset maintains 83.2 FPS. Every setting at this resolution clears 60 FPS by a wide margin, making 1080p the most forgiving and flexible environment for this combo.

At 2560x1440, performance remains strong but requires more careful selection. The Low preset runs at 101.4 FPS, offering a smooth experience with reduced detail. Medium settings still comfortably exceed 60 FPS at 76.8 FPS. High settings dip to 56.8 FPS, just below the 60 FPS target, while Ultra manages 58.6 FPS, also slightly under the threshold. The data indicates that High and Ultra at 1440p are not fully playable if the 60 FPS benchmark is strict, but they are close enough for minor adjustments or a tolerant frame rate cap.

At 3840x2160, the system struggles under higher loads. The Low preset is the only playable option, achieving 60.4 FPS, which barely clears the threshold. Medium drops to 48 FPS, High falls to 33.3 FPS, and Ultra bottoms out at 30.9 FPS. The difference between Low and Medium at 4K is 12.4 FPS, showing that even a modest preset increase has a significant impact at this resolution. The gap between High and Ultra is much smaller at 2.4 FPS, suggesting diminishing returns at the top end of the settings range.

How This Combo Ranks

The combination of the Intel Core i5-14400F and Intel Arc B580 holds a rank of 2826 out of 3720 tested combos in Thief. This places it in the lower-middle portion of the overall distribution, but this ranking must be interpreted with context. The database includes a wide range of hardware, from low-end integrated graphics to top-tier enthusiast setups. A rank in the 75th percentile (2826/3720) means that roughly 25% of tested combos are slower, and 75% are faster.

However, this rank does not diminish the fact that the combo is fully playable at 1080p and partially at 1440p. The ranking reflects absolute performance across all resolutions and presets, including the challenging 4K scenarios where this system falls below 60 FPS on all but the lowest preset. For a 2014 stealth title, the measured frame rates show that this configuration is competitive with many mid-range systems, but it is not positioned for high-refresh-rate or high-resolution gaming. The 68th percentile GPU ranking and 83rd percentile CPU ranking corroborate this; the CPU is stronger relative to its peers than the GPU, but neither component is in the top tier.

The Verdict

This PC can run Thief, and the verdict is clear based on the resolution-specific data. At 1920x1080, the answer is an unqualified yes: all four presets (Low, Medium, High, Ultra) average above 60 FPS, with the lowest being Ultra at 83.2 FPS. This is the recommended resolution for the best experience.

At 2560x1440, the system is conditionally playable. Only the Low (101.4 FPS) and Medium (76.8 FPS) presets clear the 60 FPS threshold. High and Ultra fall short at 56.8 and 58.6 FPS respectively, so players should stick to Medium or lower for a consistent frame rate.

At 3840x2160, the system is barely playable. Only the Low preset achieves 60.4 FPS, which is above the threshold but with no margin for error. Medium (48 FPS), High (33.3 FPS), and Ultra (30.9 FPS) are all below 60 FPS and would result in a noticeably less fluid experience. The verdict for 4K is that it is technically possible but not recommended for smooth gameplay.

Best Settings per Resolution

The most demanding preset that stays at or above 60 FPS at each resolution is as follows:

• 1920x1080: Ultra at 83.2 FPS. All presets are playable, so players can select the highest visual quality without any frame rate concerns.
• 2560x1440: Medium at 76.8 FPS. This is the highest preset that clears 60 FPS; High (56.8 FPS) and Ultra (58.6 FPS) are not recommended if the 60 FPS target is mandatory.
• 3840x2160: Low at 60.4 FPS. This is the only playable preset at 4K, and it just barely meets the threshold. Players seeking higher settings at this resolution would need to accept sub-60 FPS performance or reduce the resolution.
