# Thief with Intel Core i5-12600KF + Intel Arc B580

The Intel Core i5-12600KF paired with the Intel Arc B580 delivers a fascinating performance profile in Thief, a 2014 stealth classic that remains surprisingly demanding at higher settings. The measured data reveals a combo that scales predictably with resolution but shows notable sensitivity to preset choices, ultimately ranking 1267th out of 1642 tested combos in this game. This mid-pack placement suggests the pairing performs adequately for 1080p and 1440p play, but struggles to maintain smooth frame rates at 4K with higher quality settings. The combination of a 10-core Alder Lake processor with a 12 GB Battlemage GPU creates an interesting dynamic where neither component consistently becomes the bottleneck—instead, the game's engine and preset selection heavily influence which part shoulders the load.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but not uniform across settings, revealing a GPU-bound scenario at higher resolutions. At Low settings, the average frame rate falls from 150 FPS at 1920x1080 to 104.7 FPS at 2560x1440, a 30.2% reduction, then further to 58.1 FPS at 3840x2160—a cumulative 61.3% drop from 1080p. This pattern indicates the Arc B580's 13.67 TFLOPS of FP32 compute and 456.0 GB/s memory bandwidth are increasingly taxed as pixel count rises.

At Ultra settings, the scaling is more dramatic. The combo delivers 83.8 FPS at 1080p, 56.4 FPS at 1440p (a 32.7% decrease), and just 34.2 FPS at 4K (a 59.2% drop from 1080p). The 4K Ultra result of 34.2 FPS falls below the 60 FPS threshold, suggesting the GPU's 80 ROPs and 213.6 GPixel/s pixel rate cannot keep pace with the combined demands of high resolution and maximum quality. Interestingly, the gap between 1440p and 4K is smaller at Ultra (39.4% reduction) than at Low (44.5% reduction), implying that at 4K, the game becomes increasingly limited by the GPU's raw throughput rather than memory bandwidth alone.

The data indicates that 1080p to 1440p scaling is relatively gentle—the GPU retains playable performance at all settings except 4K Ultra. The 4K Low result of 58.1 FPS shows the Arc B580 can handle 4K only when graphics load is minimized, which points to the GPU as the primary limiting component at this resolution.

Settings Recommendations

The measured rows suggest that Medium settings provide the best balance of visual quality and performance across all three resolutions. At 1080p, Medium delivers 115.3 FPS, which is 26.3 FPS higher than High (89 FPS) and only 34.7 FPS below Low (150 FPS). At 1440p, Medium achieves 80.8 FPS, comfortably above the 60 FPS playability threshold, while High drops to 57.8 FPS and Ultra falls to 56.4 FPS—both marginally below ideal smoothness.

For 4K, the recommendation shifts. Medium yields 48.8 FPS and High delivers 32.6 FPS, while Low reaches 58.1 FPS. Given the data, Low is the only 4K preset that maintains near-60 FPS performance. However, the jump from Low to Medium at 4K (from 58.1 to 48.8 FPS) represents a 16% performance cost that may not justify the visual uplift on a 12 GB GPU with 19 Gbps effective memory.

At 1080p, the 83.8 FPS Ultra result is still playable, but Medium's 115.3 FPS offers a 37.6% performance advantage with presumably modest visual differences. The data suggests that Medium is the "sweet spot" preset for this combo, especially at 1440p where it maintains 80.8 FPS while High and Ultra both fall below 60 FPS.

How This Combo Ranks

This configuration ranks 1267th out of 1642 tested combos in Thief, placing it in the lower 23% of all pairings. This rank is notably lower than what the individual component percentiles might suggest—the CPU sits at the 84th percentile among all processors, and the GPU at the 66th percentile among all GPUs. The discrepancy implies that Thief's engine does not fully exploit the strengths of either component.

The CPU's nearest rivals include the Intel Core i9-10900K (average score 27829, deltaPct 0), Intel Core i5-12600K (27851, -0.1%), and Intel Core Ultra 5 125H (27872, -0.2%). The i5-12600KF's average benchmark score of 27827 places it essentially tied with the i9-10900K, suggesting the 10-core, 16-thread configuration with 20 MB of L3 cache provides comparable computational muscle to a higher-tier previous-generation part. The GPU's nearest rivals include the AMD Radeon 760M (22999, +0.1%), NVIDIA P106-100 (22950, +0.3%), and NVIDIA GeForce RTX 4060 (23181, -0.7%). The Arc B580's average score of 23021 sits within 0.7% of the RTX 4060, indicating similar raw compute capability.

The low combo rank relative to component percentiles suggests that Thief's 2014 engine may not be optimized for modern multi-core processors or the Xe2-HPG architecture. The game launched in February 2014, predating the Alder Lake architecture by nearly eight years, which could explain suboptimal thread scheduling on the 10-core hybrid design.

Measured FPS Breakdown

The complete measured dataset shows consistent performance degradation as resolution increases. At 1920x1080, the combo delivers 150 FPS on Low, 115.3 FPS on Medium, 89 FPS on High, and 83.8 FPS on Ultra. The spread from Low to Ultra is 66.2 FPS, or 44.1% of the Low value, indicating that quality presets have substantial impact at this resolution.

At 2560x1440, performance drops to 104.7 FPS on Low, 80.8 FPS on Medium, 57.8 FPS on High, and 56.4 FPS on Ultra. The 1440p results show a tighter grouping between High and Ultra (only 1.4 FPS difference), suggesting that the transition from High to Ultra adds minimal visual benefit while costing performance. The 1440p Low result of 104.7 FPS remains well above 60 FPS, but High and Ultra both fall below that threshold.

At 3840x2160, the GPU begins to struggle. Low averages 58.1 FPS, Medium drops to 48.8 FPS, High falls to 32.6 FPS, and Ultra bottoms out at 34.2 FPS. Interestingly, High and Ultra at 4K are nearly identical (32.6 vs 34.2 FPS), with Ultra actually performing 4.9% better—likely within measurement variance. The 4K results show that this combo cannot sustain 60 FPS at any preset, with even Low barely missing the mark at 58.1 FPS.

GPU Role

The Intel Arc B580's specifications explain much of the observed scaling behavior. With 12 GB of GDDR6 memory on a 192-bit bus delivering 456.0 GB/s bandwidth, the GPU has ample memory capacity for Thief's needs, but the bandwidth becomes a constraint at 4K Ultra settings. The 2560 shading units and 160 texture mapping units provide 427.2 GTexel/s texture rate, which supports the 1080p and 1440p results well.

The GPU's base and boost clocks are both 2670 MHz, indicating a fixed clock behavior that maintains consistent performance. The 80 ROPs deliver 213.6 GPixel/s, which explains the 4K performance ceiling—at 3840x2160 (8.3 million pixels), the pixel rate theoretically allows 25.7 frames per second if every pixel requires one ROP pass, though measured results exceed this due to the game's actual rendering characteristics.

The 19,600 million transistors on a 272 mm² die (72.1M transistors per mm²) using a 5 nm TSMC process gives the Arc B580 a 13.67 TFLOPS FP32 throughput. This positions the GPU at the 66th percentile among all GPUs, with an average benchmark score of 23021. In Thief, the 4K Low result of 58.1 FPS suggests the GPU can handle the game's geometry and textures when effects are minimized, but the 4K Ultra result of 34.2 FPS reveals that advanced lighting and shadow techniques from the 2014 engine tax the architecture heavily.

CPU Role

The Intel Core i5-12600KF provides substantial computational headroom that the measured data suggests is underutilized in Thief. With 10 cores and 16 threads running at a 3.70 GHz base clock and 4.90 GHz boost, the processor delivers strong multi-threaded performance—evidenced by its Cinebench R23 multi-core score of 23444 and 3DMark max threads score of 7952. The 20 MB of shared L3 cache and 1.25 MB per-core L2 cache should provide ample data locality for game workloads.

The CPU's single-thread performance is equally robust, with a 3DMark single-thread score of 1016 and Cinebench R15 single-core score of 333. This matters for Thief, a 2014 title likely designed around single or dual-core execution. The 3DMark 2-thread score of 1995 indicates strong dual-core performance, which aligns with the game's era. However, the fact that 4K Low (58.1 FPS) and 1080p Low (150 FPS) show such a wide spread—a 61.3% reduction—proves the GPU, not CPU, becomes the limiting factor at higher resolutions.

The CPU's percentile ranking of 84th among all processors, with an average benchmark score of 27827, shows it performs comparably to the Intel Core i9-10900K (deltaPct 0) and just 0.1% behind the i5-12600K. In Thief, the 1080p Low result of 150 FPS likely approaches the engine's frame rate ceiling on this CPU, while the 4K Ultra result of 34.2 FPS is purely GPU-bound. The data implies the CPU has significant headroom even at 4K, as evidenced by the 1080p Low result exceeding 150 FPS.
