Thief

The Intel Core i5-14600KF paired with the Intel Arc B580 delivers a clear, tiered performance profile in Thief: strong at 1080p, solid at 1440p with a settings ceiling, and not viable at 4K. Measured data across twelve resolution and settings combinations shows a system that scales predictably with graphical load, but the GPU becomes the decisive factor at higher resolutions. This analysis walks through the benchmark results, ranks the combo against other tested hardware, and identifies which settings keep frame rates above the 60 FPS playability threshold.

How This Combo Ranks

The combination of the Intel Core i5-14600KF and the Intel Arc B580 ranks 2805 out of 3720 tested combos for Thief. That places the system in the 75th percentile of all tested hardware configurations, meaning roughly a quarter of tested combos perform better in this specific title. The rank is not a reflection of a weak component set; rather, it shows that Thief, a 2014 stealth title, does not heavily tax modern CPUs. The CPU sits in the 90th percentile among all processors in general benchmark data, while the GPU ranks in the 68th percentile among all graphics cards. The gap between those two percentiles indicates the Arc B580 is the limiting factor in this pairing.

The combo rank of 2805 out of 3720 is driven by the GPU’s mid-tier standing. The CPU’s general benchmark average score of 49394 places it among high-end desktop processors, but Thief’s frame rates are constrained by the graphics card at every resolution above 1080p. At 1920x1080, the system achieves 82.3 FPS on Ultra settings, which is comfortably above the 60 FPS threshold. At 2560x1440, the same Ultra preset drops to 55.4 FPS, just below playable. At 3840x2160, even Low settings only reach 58 FPS. This pattern—where the GPU’s percentile rank (68) is far below the CPU’s (90)—explains why the combo rank is not higher.

For context, the CPU’s nearest rivals in general benchmarks are the AMD Ryzen 9 7900, which scores 0.3% higher, and the AMD Ryzen 7 PRO 5755G at 0.4% higher. The Intel Core Ultra 5 245 trails by 0.8%, while the AMD Ryzen AI Max+ 388 leads by 0.8%. These deltas are negligible for gaming, confirming that swapping the CPU for any of these alternatives would not meaningfully change Thief’s performance. The GPU’s nearest rivals show similar proximity: the AMD Radeon RX 580 2048SP scores 0.2% higher, the NVIDIA GeForce RTX 2080 trails by 0.6%, the RTX 3080 leads by 0.7%, and the NVIDIA P106-100 leads by 1.0%. In practice, any of these GPUs would produce nearly identical frame rates in Thief.

CPU and GPU Roles

The data shows a clear division of labor between the CPU and GPU in Thief. At 1920x1080, the system delivers 151.7 FPS on Low settings, 112.3 FPS on Medium, 89.1 FPS on High, and 82.3 FPS on Ultra. The drop from Low to Ultra is 69.4 FPS, a 45.7% reduction. This scaling is entirely attributable to the GPU, as the CPU remains underutilized at these frame rates. The i5-14600KF’s single-core benchmark score of 4594 in Cinebench R23 and its 4273 score in Passmark single-thread tests indicate ample headroom for a 2014 title.

At 2560x1440, the same settings produce 103.7 FPS (Low), 77.2 FPS (Medium), 61.6 FPS (High), and 55.4 FPS (Ultra). The transition from 1080p to 1440p reduces frame rates by 31.7% on Low, 31.3% on Medium, 30.9% on High, and 32.7% on Ultra. This consistent ~31% drop across all presets is a hallmark of GPU-bound rendering. The CPU’s role is static; the graphics card is doing progressively more work per frame.

At 3840x2160, the GPU’s dominance becomes absolute. Low settings yield 58 FPS, Medium drops to 48.4 FPS, High falls to 34.5 FPS, and Ultra bottoms out at 32.1 FPS. The reduction from 1440p to 4K is 44.1% on Low, 37.3% on Medium, 44.0% on High, and 42.1% on Ultra. This is a purely GPU-limited scenario. The Arc B580’s 13.67 TFLOPS of FP32 performance and 456.0 GB/s memory bandwidth are insufficient for 4K in this title, regardless of CPU capability.

The CPU’s contribution is measurable only in the sense that it never becomes a bottleneck. The i5-14600KF has 14 cores and 20 threads with a boost clock of 5.30 GHz, and its Cinebench R23 multi-core score of 32544 places it far above any requirement Thief could impose. Across all resolutions, the frame rate differences between settings are proportional to GPU workload, not CPU workload. The verdict is unambiguous: for this game, the Arc B580 dictates performance at every resolution, while the i5-14600KF provides a comfortable ceiling that never limits the GPU.

Similar Performance Alternatives

Hardware with benchmark scores close to the i5-14600KF would behave identically in Thief. The AMD Ryzen 9 7900 has an average benchmark score of 49228, a 0.3% delta from the i5-14600KF’s 49394. The AMD Ryzen 7 PRO 5755G scores 49196, just 0.4% lower. The Intel Core Ultra 5 245 trails by 0.8% at 48995. The AMD Ryzen AI Max+ 388 leads by 0.8% at 49796. For a game like Thief that relies on single-threaded performance, these differences are imperceptible. Any of these CPUs paired with the Arc B580 would produce frame rates within 1% of each other.

On the GPU side, the nearest rivals are more varied in architecture but similar in raw benchmark score. The AMD Radeon RX 580 2048SP scores 23061, which is 0.2% higher than the Arc B580’s 23021. The NVIDIA GeForce RTX 2080 scores 22895, a 0.6% deficit. The NVIDIA GeForce RTX 3080 scores 23172, a 0.7% advantage. The NVIDIA P106-100 scores 23249, a 1.0% lead. In Thief, these GPUs would deliver frame rates within 1-2 FPS of each other at any given resolution and settings preset. The RTX 3080, despite being a more powerful card in other titles, shows no meaningful advantage here because the benchmark score delta is under 1%.

What this means in practice is that the measured FPS data for this combo is representative of a wide range of similarly-scoring hardware. A system with an AMD Ryzen 9 7900 and an RTX 3080 would produce nearly identical results in Thief, as would a system with an Intel Core Ultra 5 245 and an RX 580 2048SP. The performance envelope is defined by the GPU’s 68th percentile standing, not by any specific brand or model. For users upgrading from an older CPU, the data confirms that the i5-14600KF is not the constraint. For those considering a GPU swap, any card with an average benchmark score near 23000 will match the Arc B580’s Thief performance.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings average 151.7 FPS, Medium averages 112.3 FPS, High averages 89.1 FPS, and Ultra averages 82.3 FPS. The spread from Low to Ultra is 69.4 FPS, with the largest single drop occurring between Low and Medium at 39.4 FPS. The difference between High and Ultra is only 6.8 FPS, suggesting diminishing returns at the top end.

At 2560x1440, performance scales down proportionally. Low settings average 103.7 FPS, Medium averages 77.2 FPS, High averages 61.6 FPS, and Ultra averages 55.4 FPS. The gap between Low and Ultra is 48.3 FPS. Notably, Ultra falls 4.6 FPS short of the 60 FPS threshold, while High clears it by 1.6 FPS. This makes High the most demanding playable preset at this resolution.

At 3840x2160, the GPU is overwhelmed. Low settings average 58 FPS, which is 2 FPS below the playability threshold. Medium averages 48.4 FPS, High averages 34.5 FPS, and Ultra averages 32.1 FPS. The difference between High and Ultra is only 2.4 FPS, indicating that both presets are equally unplayable. The system cannot maintain 60 FPS at any settings preset in 4K.

The data shows no min or max FPS values for any measurement, only averages. This means the analysis relies on average frame rates alone. The consistency of the scaling—roughly 31% reduction from 1080p to 1440p and another 40% from 1440p to 4K—suggests stable performance without extreme frame time spikes, but the absence of min/max data prevents a full assessment of frame pacing.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which averages 82.3 FPS. This is the highest settings preset available, and it clears the threshold by 22.3 FPS. Lower presets also remain playable, with High at 89.1 FPS, Medium at 112.3 FPS, and Low at 151.7 FPS. There is no reason to reduce settings below Ultra at this resolution for playability, though users seeking higher frame rates could drop to High for a 6.8 FPS gain.

At 2560x1440, the best playable preset is High, averaging 61.6 FPS. This clears the 60 FPS threshold by only 1.6 FPS, leaving minimal headroom. Medium averages 77.2 FPS and Low averages 103.7 FPS, both of which are also playable. Ultra averages 55.4 FPS, which is below the threshold and therefore not recommended. For users who prefer a safety margin above 60 FPS, Medium at 77.2 FPS is a more comfortable choice, but High is technically the highest playable preset.

At 3840x2160, no preset achieves 60 FPS. The closest is Low at 58 FPS, which is 2 FPS short. Medium averages 48.4 FPS, High averages 34.5 FPS, and Ultra averages 32.1 FPS. There is no best settings preset at this resolution because none are playable. Users must either lower the resolution to 1440p or accept sub-60 FPS performance.

The Verdict

Can this PC run Thief? The answer depends entirely on resolution. At 1920x1080, the system runs the game flawlessly, with all four settings presets clearing the 60 FPS threshold. Ultra settings deliver 82.3 FPS, and even the most demanding preset leaves 22 FPS of headroom. This is a fully playable configuration for 1080p gaming.

At 2560x1440, the system is playable but with a caveat. High settings average 61.6 FPS, which is just above the threshold. Medium at 77.2 FPS and Low at 103.7 FPS provide more comfortable margins. Ultra is not playable at 55.4 FPS. Users with 1440p monitors should use High settings or lower for a smooth experience.

At 3840x2160, the system cannot run Thief at playable frame rates. The best result is Low settings at 58 FPS, which falls 2 FPS short of the threshold. All other presets are significantly below 60 FPS. The Arc B580’s 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are insufficient for 4K in this title, regardless of the CPU’s capability.

The overall verdict is that this combo is a capable 1080p and 1440p gaming system for Thief, but not a 4K system. The i5-14600KF provides more than enough processing power, ranking in the 90th percentile among CPUs. The Arc B580, ranking in the 68th percentile among GPUs, is the bottleneck at higher resolutions. For the best experience, users should target 1920x1080 with Ultra settings for 82.3 FPS, or 2560x1440 with High settings for 61.6 FPS. At 4K, the system falls short of the 60 FPS playability threshold on every settings preset.
