Thief

The Intel Core i3-12100F and Intel Arc B580 pairing produces a remarkably consistent scaling pattern in Thief, with the CPU providing a solid foundation and the GPU governing performance across the tested settings and resolutions. The data reveals a system that is well-balanced at 1080p but increasingly GPU-bound as resolution climbs, making settings choices critical for maintaining smooth gameplay.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake generation, operating at a base clock of 3.30 GHz and boosting to 4.30 GHz. Its benchmark profile shows a substantial gap between single-threaded and multi-threaded performance, with a 3dmark single-thread score of 893 versus a 4-thread score of 2859 and an 8-thread score of 4026. This pattern suggests that Thief, a 2014 stealth title, does not heavily tax the CPU’s multi-threading capabilities; the game’s frame rates are far more sensitive to graphical settings than to processor workload.

In the measured results, the CPU’s headroom is evident at 1080p Low, where the system achieves 149.2 FPS. At this setting, the GPU is not the limiting factor, yet the frame rate still scales cleanly upward from higher presets, indicating the i3-12100F is not bottlenecking even in lighter loads. The processor’s Cinebench R23 multicore score of 11912 and single-core score of 1681 reinforce that it can handle the game’s logic and draw calls without issue, as Thief’s engine does not require the thread counts found in modern multi-core-heavy titles.

The CPU’s position relative to rivals further contextualizes its role. The i3-12100F’s average benchmark score of 13516 places it 0.1% behind the AMD Ryzen Threadripper PRO 3975WX (13534) and 0.4% ahead of the Intel Core i7-1250U (13462). It also leads the Intel Core i3-10105 by 0.6% and the Intel Core i7-7700K by 1.8%. These margins are negligible, meaning the i3-12100F’s performance in Thief will be effectively indistinguishable from those processors. The data shows that the CPU’s 12 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support are more than sufficient for a game of this era, as the frame rates across all resolutions and settings remain stable without signs of CPU-induced stutter.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B580 is built on the Xe2-HPG architecture with a 5 nm process, featuring 12 GB of GDDR6 memory on a 192-bit bus, delivering 456.0 GB/s of bandwidth. Its boost clock is fixed at 2670 MHz, and it offers 2560 shading units, 160 TMUs, and 80 ROPs. In Thief, the GPU’s role is dominant, as evidenced by the dramatic FPS swings when changing settings at any given resolution. The GPU’s average benchmark score of 23021 places it in the 66th percentile of all GPUs, and it sits just 0.7% behind the NVIDIA GeForce RTX 4060 (23181) while being 0.1% ahead of the AMD Radeon 760M (22999) and 1.3% ahead of the NVIDIA GeForce RTX 4060 Mobile (22729).

At 1080p, the B580’s capabilities are fully utilized, with scores ranging from 149.2 FPS at Low to 80 FPS at Ultra. The 12 GB VRAM is not a limiting factor in this game, as even at 4K Ultra with 36.1 FPS, the memory bandwidth remains sufficient for texture streaming. The GPU’s pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s suggest that Thief’s visual effects, such as shadows and lighting, are handled efficiently. The data indicates that the B580 is the primary driver of performance differences, as the FPS drops are consistent with GPU load rather than CPU constraints. For instance, moving from 1080p High (85.7 FPS) to 4K High (35.1 FPS) represents a 59% reduction, which aligns with the increased pixel count and graphical complexity.

Settings Recommendations — which preset gives the best experience per the measured rows

Given the measured results, the optimal settings depend on the target resolution and refresh rate. At 1080p, the High preset delivers 85.7 FPS, which is smooth for most displays, while Ultra drops to 80 FPS—a marginal difference of 5.7 FPS that may not justify the visual upgrade. Medium at 112.9 FPS offers a significant boost over High without a proportional visual loss, making it the sweet spot for high-refresh-rate monitors. Low at 149.2 FPS is excessive for most users, but it demonstrates the system’s ceiling.

At 1440p, the High preset dips to 57.8 FPS, which is playable but not ideal for fast-paced stealth sequences. Medium at 81.2 FPS provides a better balance, keeping frame rates above 60 FPS while retaining moderate visual fidelity. Ultra at 53.9 FPS is borderline, and the 27.3 FPS gap between High and Medium suggests that Medium is the recommended choice for consistent smoothness. Low at 105.2 FPS remains an option for competitive play, but the visual downgrade is pronounced.

At 4K, the situation changes drastically. High yields 35.1 FPS, which is below the threshold for comfortable gameplay. Medium at 44.9 FPS is still not ideal, and Ultra at 36.1 FPS is similarly constrained. Low at 60.8 FPS is the only preset that achieves a playable frame rate, making it the sole viable option for 4K. The data shows that the B580 cannot sustain high settings at this resolution, so users with 4K displays should either accept Low or reduce their resolution.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of GPU-bound scaling. At 1080p High, the system runs at 85.7 FPS; at 1440p High, it drops to 57.8 FPS (a 32.6% reduction); and at 4K High, it falls to 35.1 FPS (a 59% reduction from 1080p). This steep decline is characteristic of a GPU that is fully utilized, as the pixel count quadruples from 1080p to 4K, while the CPU’s workload remains relatively constant.

The same trend holds for other settings. At Low, 1080p produces 149.2 FPS, 1440p produces 105.2 FPS, and 4K produces 60.8 FPS—a 59.3% drop from 1080p to 4K. At Medium, the values are 112.9, 81.2, and 44.9 FPS, respectively, showing a 60.2% reduction. Ultra follows with 80, 53.9, and 36.1 FPS, a 54.9% decline. The consistency of these drops—around 55-60%—indicates that the GPU is the limiting component across all settings. If the CPU were the bottleneck, the frame rates would plateau at higher resolutions, but the data shows no such leveling off.

The B580’s 12 GB VRAM and 456.0 GB/s bandwidth are sufficient for 4K, as the FPS drops are proportional to resolution rather than sudden, which would indicate memory or bandwidth constraints. The pixel rate of 213.6 GPixel/s suggests the GPU is compute-bound, not memory-bound. This analysis confirms that Thief is primarily a GPU workload for this system, and users should prioritize graphical settings over CPU upgrades when seeking higher frame rates.
