Thief

The Intel Core i5-14600K and Intel Arc B580 combination delivers a performance profile in Thief that is heavily influenced by the graphics card, with the CPU providing ample headroom. The Arc B580’s benchmark scores place it at the 68th percentile among all GPUs, with an average score of 23021. Its nearest rivals in synthetic benchmarks include the AMD Radeon RX 580 2048SP, which scores 23061 (a delta of -0.2%), the NVIDIA GeForce RTX 2080 at 22895 (delta 0.6%), and the NVIDIA GeForce RTX 3080 at 23172 (delta -0.7%). This clustering indicates that while the B580’s raw compute is competitive with these cards, its actual in-game performance in Thief will be the deciding factor. On the CPU side, the i5-14600K sits at the 90th percentile among all CPUs, with an average benchmark score of 48618. Its nearest rivals include the Intel Xeon Gold 5318H (48698, delta -0.2%), the AMD EPYC 4345P (48470, delta 0.3%), the Intel Core Ultra 5 245HX (48287, delta 0.7%), and the Intel Core Ultra 5 245 (48995, delta -0.8%). The negligible deltas—all under 1%—mean that swapping to any of these CPUs would yield nearly identical frame rates in Thief, assuming the GPU remains the same.

Similar Performance Alternatives

For users considering hardware substitutions, the data suggests that the GPU is the primary bottleneck in Thief, making GPU swaps the most impactful change. The Arc B580’s nearest rival, the AMD Radeon RX 580 2048SP, has a nearly identical average benchmark score (23061 vs 23061, delta -0.2%), meaning it would likely produce very similar frame rates in Thief across all resolutions and settings. The NVIDIA GeForce RTX 2080, with a score of 22895 (delta 0.6%), is also a close match, though its older architecture may handle the game’s DirectX features differently. Interestingly, the NVIDIA GeForce RTX 3080 is listed as a rival with a score of 23172 (delta -0.7%), which is within 1% of the B580’s score; despite the RTX 3080 typically being a much faster card in modern titles, the benchmark data here suggests that in this specific synthetic suite, they perform almost identically. For CPU-side alternatives, the Intel Core Ultra 5 245 and the Intel Xeon Gold 5318H are the closest matches, with deltas of -0.8% and -0.2% respectively. Given that the i5-14600K’s multi-core performance (Cinebench R23 multi-core score of 24491) is far above what Thief requires, any of these rival CPUs would maintain the same 60 FPS thresholds observed in this analysis. The practical takeaway is that users with any of these GPUs or CPUs should expect similar playability outcomes, with the GPU choice dictating the resolution and preset ceilings.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the CPU and GPU in Thief. At 1920x1080, the GPU is the limiting factor, as evidenced by the scaling from Low to Ultra settings. The average FPS drops from 152 at Low to 84.9 at High, and further to 83.7 at Ultra. This 45% reduction from Low to Ultra indicates that the GPU’s fill rate and shading capabilities are being stressed, while the CPU’s 14 cores and 20 threads are more than sufficient to feed the GPU. Moving to 2560x1440, the GPU pressure increases, with average FPS falling from 103.1 at Low to 58 at High, and 57.1 at Ultra. The gap between High and Ultra narrows to less than 1 FPS, suggesting that the GPU is hitting a compute ceiling rather than a memory bandwidth limit. At 3840x2160, the GPU is clearly the dominant constraint: average FPS plummets to 32.4 at High and 30.9 at Ultra, while even Medium only manages 45.7. The CPU’s role becomes negligible at 4K, as the i5-14600K’s single-core performance (Cinebench R23 single-core score of 2064) is more than adequate to handle the game’s logic and draw calls. The scaling pattern—where FPS drops by roughly 30-40% from 1080p to 1440p, and another 40-45% from 1440p to 4K at the same settings—confirms that Thief is a GPU-bound title, especially at higher resolutions. The CPU’s influence is only perceptible at 1080p Low, where the 152 FPS average suggests the game is running at a rate where CPU overhead could become a factor, but even then, the i5-14600K’s PassMark single-thread score of 4270 ensures no stutter.

Measured FPS Breakdown

At 1920x1080, the combination delivers playable performance across all presets. The Low preset achieves an average of 152 FPS, which is more than double the 60 FPS threshold. Medium produces 111.3 FPS, High drops to 84.9 FPS, and Ultra yields 83.7 FPS. The difference between High and Ultra is minimal (1.2 FPS), indicating that the Ultra preset’s additional effects are not heavily taxing the Arc B580 at this resolution. At 2560x1440, the performance profile changes significantly. Low remains smooth at 103.1 FPS, and Medium clears the threshold comfortably at 76.8 FPS. However, High falls just short of the 60 FPS target, averaging 58 FPS, and Ultra is slightly lower at 57.1 FPS. This places the playable ceiling at Medium for 1440p. At 3840x2160, the GPU struggles to maintain playability. Low is the only preset that clears 60 FPS, averaging 62.4 FPS. Medium drops to 45.7 FPS, High to 32.4 FPS, and Ultra to 30.9 FPS. The steep decline from Low to Medium (a 27% reduction) and from Medium to High (a 29% reduction) highlights the memory bandwidth and shading limitations of the B580 at 4K. Notably, the data does not include min or max FPS values, so the analysis relies solely on average FPS, which may mask occasional dips below the threshold.

The Verdict

This PC can run Thief, but the playable experience depends heavily on resolution and settings. At 1920x1080, the system clears the 60 FPS threshold at all four presets: Low (152 FPS), Medium (111.3 FPS), High (84.9 FPS), and Ultra (83.7 FPS). This makes 1080p the most versatile resolution, allowing users to enable the Ultra preset without sacrificing smoothness. At 2560x1440, the system is playable only at Low (103.1 FPS) and Medium (76.8 FPS). The High and Ultra presets fall short, averaging 58 and 57.1 FPS respectively, which is below the 60 FPS playability threshold. At 3840x2160, the only playable setting is Low, which averages 62.4 FPS. Every other preset—Medium (45.7 FPS), High (32.4 FPS), and Ultra (30.9 FPS)—fails to meet the 60 FPS standard. The verdict is clear: this combination is a strong 1080p performer, a capable 1440p machine at medium settings, and a marginal 4K option limited to low settings. For users targeting 4K with higher visual fidelity, the data indicates the GPU is the bottleneck, and no CPU upgrade would change this outcome.

Best Settings per Resolution

At 3840x2160, the only preset that maintains an average at or above 60 FPS is Low, with an average of 62.4 FPS. This is the recommended setting for 4K, as Medium drops to 45.7 FPS, which is below the playable threshold. At 2560x1440, the most demanding preset that stays at or above 60 FPS is Medium, with an average of 76.8 FPS. While Low achieves 103.1 FPS, Medium offers a better visual experience without sacrificing smoothness. At 1920x1080, the Ultra preset is fully playable with an average of 83.7 FPS, making it the best choice for visual quality. The data shows that High (84.9 FPS) and Ultra (83.7 FPS) are nearly identical in performance, so users can enable Ultra without penalty. The recommended settings by resolution are: 4K Low (62.4 FPS), 1440p Medium (76.8 FPS), and 1080p Ultra (83.7 FPS).

How This Combo Ranks

Among all tested CPU and GPU combinations in the database, this pairing ranks 2828 out of 3720 combos, placing it in the 76th percentile. This rank reflects the overall capability of the system across all games, not just Thief. In Thief specifically, the performance is sufficient for 1080p Ultra and 1440p Medium, but the 4K results are limited. The rank of 2828 suggests that while the i5-14600K is a high-end CPU, the Arc B580’s mid-range GPU performance (68th percentile among GPUs) holds the combination back in more demanding scenarios. The fact that the B580’s nearest rivals include the RTX 3080, which typically scores much higher in other games, indicates that Thief’s specific rendering workload is not particularly favorable to the B580’s architecture. For users comparing this combo to others, the 3720 total combos mean that 892 other pairings perform better overall, but the i5-14600K’s strong CPU scores (90th percentile) ensure that future GPU upgrades would significantly improve the rank without requiring a CPU change.
