Thief

Measured FPS Breakdown

The recorded data for the Intel Core i5-10400F paired with the Intel Arc B580 in Thief reveals a clear performance curve across the three tested resolutions. At 1920x1080, the combo delivers consistently high frame rates. The Low preset averages 126.9 FPS, which is the strongest result in the entire dataset. Medium follows closely at 112.9 FPS, while High drops to 86 FPS and Ultra settles at 83.8 FPS. The gap between Medium and High is substantial, a 26 FPS difference, while the drop from High to Ultra is comparatively modest at just 2.2 FPS.

Moving to 2560x1440, the same pattern holds but with lower absolute numbers. Low averages 104.6 FPS, Medium 79.3 FPS, High 56.7 FPS, and Ultra 57.1 FPS. Notably, High and Ultra produce nearly identical averages at this resolution, with Ultra actually edging out High by 0.4 FPS. This suggests the Ultra preset's additional graphical demands are offset by some inefficiency in the High preset, or the workloads are simply similar enough at this resolution to converge. The Medium preset remains comfortably above the 60 FPS threshold, but High and Ultra fall below it.

At 3840x2160, performance drops significantly. Low averages 61.3 FPS, which is the only setting that clears the 60 FPS mark. Medium averages 43.5 FPS, High 36.1 FPS, and Ultra 31 FPS. The scaling from Low to Medium is a 17.8 FPS loss, and from Medium to High another 7.4 FPS loss. The Ultra preset delivers the weakest result, nearly half the frame rate of Low. These numbers indicate that 4K gaming on this combo requires substantial settings reductions to remain playable.

The database does not include minimum or maximum frame time data for any resolution or preset. All recorded values are averages, meaning the analysis relies on mean performance rather than frame pacing consistency. For a stealth game like Thief, where sudden visibility changes and complex lighting can cause spikes, this is a limitation worth noting, but the averages still provide a reliable baseline for expected performance.

Across all resolutions, the scaling from Low to Ultra is consistent in direction: higher settings always reduce average FPS. The magnitude varies, however. At 1080p, Ultra is 34% slower than Low. At 1440p, Ultra is 45% slower than Low. At 4K, Ultra is 49% slower than Low. This widening gap suggests the GPU becomes the limiting factor as resolution increases, with the CPU's role diminishing.

How This Combo Ranks

The Intel Core i5-10400F and Intel Arc B580 combination ranks 2846 out of 3720 tested combos in Thief. This places it in the 23rd percentile of all recorded systems, meaning roughly three-quarters of tested configurations deliver higher average frame rates. The rank reflects the entire system, not just the GPU or CPU individually, so it accounts for potential bottlenecks in either component.

The GPU itself sits at the 68th percentile among all tested graphics cards, according to its average benchmark score. The CPU also ranks at the 68th percentile among all processors. On paper, both components are mid-to-upper tier individually, yet the combined system lands lower in the game-specific ranking. This discrepancy suggests either the game is particularly demanding in ways that penalize this pairing, or the benchmark methodology captures a broader range of hardware that outperforms this specific combination.

Within the game's own leaderboard, a rank of 2846 out of 3720 means this combo is closer to the bottom quartile than the top. Many systems with older or less powerful individual components may still achieve higher in-game scores due to more favorable CPU-GPU balance. The Intel Arc B580's 12 GB of VRAM and 456.0 GB/s bandwidth are strong specifications, but Thief's engine may not fully utilize them, particularly at lower resolutions where CPU overhead matters more.

The recorded data shows the combo's strengths in absolute terms, but the rank contextualizes it: this is not a top-tier gaming system for Thief. It is a capable mid-range pairing that delivers playable results at lower settings, but it does not compete with high-end configurations in the database. For users comparing upgrades, the rank provides a reference point: many alternative builds will offer better in-game performance, even if the individual components are similarly priced.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-10400F, based on average benchmark scores, include the Intel Xeon 6756E, which scores 14163 compared to the i5-10400F's 14185, a difference of 0.2%. The Intel Core 7 160UL scores 14232, 0.3% higher. The AMD EPYC 7552 scores 14115, 0.5% lower. The AMD Ryzen 3 7320C scores 14277, 0.6% higher. These deltas are minimal, meaning any of these processors would deliver nearly identical CPU-bound performance in Thief. The Xeon 6756E and EPYC 7552 are server-class chips, but their compute scores align closely enough that gaming performance would be indistinguishable from the i5-10400F in this title.

For the Intel Arc B580, the nearest GPU rivals are the AMD Radeon RX 580 2048SP, which scores 23061 versus the Arc's 23021, a 0.2% difference. The NVIDIA GeForce RTX 2080 scores 22895, 0.6% lower. The NVIDIA GeForce RTX 3080 scores 23172, 0.7% higher. The NVIDIA P106-100 scores 23249, 1% higher. These four GPUs bracket the Arc B580 closely, with the P106-100 being the fastest by a small margin. In Thief, swapping the Arc B580 for any of these would yield frame rates within roughly 1% of the recorded values, assuming the CPU remains the same.

The practical implication is that users with any of these CPU or GPU alternatives would see essentially identical behavior. The RTX 3080, despite being a more powerful card in other contexts, does not meaningfully outperform the Arc B580 in this game based on the aggregate score. The RX 580 2048SP, an older card, matches the Arc B580's performance within noise. This suggests Thief's engine is not particularly sensitive to the architectural differences among these GPUs, and the bottleneck may lie elsewhere, possibly in the CPU or the game's own rendering paths.

The Verdict

This system can run Thief, but the playable settings depend heavily on resolution. At 1920x1080, all four presets clear the 60 FPS threshold. Low averages 126.9 FPS, Medium 112.9 FPS, High 86 FPS, and Ultra 83.8 FPS. The verdict for 1080p is unambiguous: every setting is playable, and Ultra is the recommended choice since it still maintains a comfortable margin above 60 FPS.

At 2560x1440, the system remains playable on Low and Medium. Low averages 104.6 FPS, and Medium averages 79.3 FPS. High and Ultra fall short, with 56.7 FPS and 57.1 FPS respectively, both below the 60 FPS threshold. The verdict for 1440p is that users must choose Medium or lower for a consistent experience. The gap between Medium and High is 22.6 FPS, so the step up in visual quality comes at a significant performance cost.

At 3840x2160, only Low is playable, averaging 61.3 FPS. Medium drops to 43.5 FPS, High to 36.1 FPS, and Ultra to 31 FPS. The verdict for 4K is that the system can run the game, but only at the lowest settings. Even then, the 61.3 FPS average is just barely above the 60 FPS threshold, leaving little headroom for demanding scenes. Users prioritizing 4K should expect to sacrifice most graphical features.

The database's playable threshold is 60 FPS, and the verdict aligns with that cutoff. For a stealth game, frame rates above 60 FPS are not strictly necessary, but the data indicates this system provides them at 1080p across all settings, at 1440p for two settings, and at 4K for only the lowest setting. The overall answer is yes, this PC can run Thief, but the definition of "run" varies by resolution and preset.

Q: Does the game's release date affect the performance expectations?

A: Thief was released on 2014-02-24, and the recorded data reflects actual measurements on modern hardware. The game's age means it does not use newer rendering techniques, which likely explains why even mid-range components like the Arc B580 can achieve high frame rates at 1080p.

Best Settings per Resolution

At 3840x2160, the only setting that clears the 60 FPS threshold is Low, with an average of 61.3 FPS. This is the recommended configuration for 4K. Medium falls to 43.5 FPS, so the visual upgrade is not worth the 17.8 FPS loss. Users at this resolution must accept minimal graphical features to maintain playability.

At 2560x1440, the best setting is Medium, averaging 79.3 FPS. This provides a 24.6 FPS improvement over Low's 104.6 FPS is not the target, but Medium balances quality and performance better than Low. High and Ultra are not recommended since they drop below 60 FPS, with 56.7 FPS and 57.1 FPS respectively. The 0.4 FPS difference between High and Ultra is negligible, but neither meets the playable threshold.

At 1920x1080, the best setting is Ultra, averaging 83.8 FPS. This is the most demanding preset that stays above 60 FPS, and it does so with a 23.8 FPS margin. High averages 86 FPS, slightly higher, but Ultra offers more visual features for only a 2.2 FPS loss. Medium and Low are also playable, but they provide no reason to sacrifice quality when Ultra remains comfortable.

The data suggests a clear hierarchy: 1080p users should max out settings, 1440p users should settle for Medium, and 4K users must use Low. The Intel Core i5-10400F and Intel Arc B580 pairing is best suited for 1080p gaming in Thief, with acceptable 1440p performance at reduced settings and limited 4K capability. The recorded averages show no minimum or maximum FPS values, so the analysis relies on mean performance, but the consistency of the scaling across resolutions provides confidence in these recommendations.
