Thief

Thief, a 2014 stealth title, exhibits a substantial performance scaling curve when paired with the AMD Ryzen 5 5600 and Intel Arc B570. The measured data shows a clear transition from a fluid high-refresh experience at 1080p to a demanding, often sub-60 FPS scenario at 4K, indicating that the graphics card becomes the primary bottleneck as resolution increases. This analysis breaks down the measured frame rates, setting recommendations, and the distinct roles played by the CPU and GPU in this specific configuration.

Resolution Scaling

The performance drop from 1920x1080 to 3840x2160 is steep and consistent across all tested settings, underscoring the dominance of the GPU in determining frame rates at higher resolutions. At the High preset, the average frame rate falls from 77 FPS at 1080p to 53 FPS at 1440p, a reduction of approximately 31%. Moving to 4K, the average drops further to 31 FPS, which is a 60% decrease from the 1080p figure. This pattern is mirrored in the Low preset, where the average FPS goes from 133 at 1080p to 91 at 1440p and finally to 54 at 4K.

The scaling behavior provides a clear diagnostic. At 1080p, the performance gap between the Low and Ultra presets is 60 FPS (133 vs. 73), demonstrating that the GPU has headroom to render more complex scenes. However, at 4K, the gap narrows to 25 FPS (54 vs. 29), suggesting that the GPU is nearing its absolute limit and that frame rates are constrained by raw pixel throughput. The 4K results, with averages of 31, 41, and 29 FPS for High, Medium, and Ultra respectively, all fall below the 60 FPS threshold, indicating that this combination is not suited for 4K gaming with these settings.

The data suggests that the limiting component at 4K is unequivocally the Intel Arc B570. The Ryzen 5 5600, with its 6 cores and 12 threads, is demonstrably capable of high frame rates at lower resolutions, as evidenced by the 133 FPS average at 1080p Low. As resolution increases, the workload shifts from the CPU to the GPU, and the B570's performance characteristics become the deciding factor. The 1440p results are a middle ground; while playable at all presets, the High and Ultra settings (53 and 50 FPS) hover near the edge of smooth gameplay, suggesting that users targeting a locked 60 FPS should consider adjusting settings.

Settings Recommendations

For each resolution, the measured data points to a specific preset that offers the most balanced experience in terms of frame rate and visual fidelity. The Medium preset consistently provides a significant boost over High and Ultra while closing much of the gap to Low.

At 1920x1080, the Medium preset delivers an average of 101 FPS, with a minimum of 86 FPS. This is a substantial 24 FPS improvement over the High preset (77 FPS), and it remains well above the 60 FPS threshold for smooth gameplay. The Ultra preset, at 73 FPS, is also playable, but the 28 FPS penalty compared to Medium is significant for a likely marginal visual gain. For users with 144Hz displays, the Low preset at 133 FPS is the only option that approaches that refresh rate. The data indicates that Medium is the sweet spot for a high-quality, high-frame-rate experience at this resolution.

At 2560x1440, the Medium preset again provides the best balance, averaging 69 FPS with a minimum of 59 FPS. This keeps the experience mostly smooth, albeit with occasional dips below 60 FPS. The High preset drops to 53 FPS, which introduces noticeable judder in a stealth game where smooth camera movement is important. The Low preset, at 91 FPS, is the only option that guarantees a locked 60 FPS experience with significant headroom. Therefore, for a fixed 60Hz display, Medium is the recommended choice, while Low is the safer bet for maintaining a consistent frame rate.

At 3840x2160, the situation is more challenging. No preset achieves a 60 FPS average. The highest average is found at Low, with 54 FPS. The Medium preset averages 41 FPS, with a minimum of 35 FPS, which is a playable but less fluid experience. High and Ultra fall to 31 and 29 FPS respectively, making them unsuitable for a game that relies on timing and awareness. The recommendation for 4K is to use the Low preset if playability is the priority, as it is the only setting that keeps the average FPS above 50.

CPU Role

The AMD Ryzen 5 5600 plays a supporting role in this configuration, providing enough processing power to avoid becoming a bottleneck at the tested resolutions. The CPU is a 6-core, 12-thread part based on the Zen 3 architecture, with a base clock of 3.50 GHz and a boost clock of 4.40 GHz. Its performance in synthetic benchmarks, such as a Cinebench R23 multi-core score of 18,309 and a single-core score of 2,584, places it in the 74th percentile of all CPUs, indicating solid mainstream performance.

In the context of Thief, the game's engine appears to be well-optimized for the 5600's capabilities. The sharp increase in frame rates when lowering resolution, particularly the jump from 77 FPS at 1080p High to 91 FPS at 1440p Low, suggests that the CPU is not the primary constraint. If the CPU were the limiting factor, the frame rates would remain relatively flat regardless of resolution. Instead, the data shows a clear scaling pattern that is characteristic of a GPU-bound scenario. The 12 threads ensure that background tasks and the game's main thread have ample resources, preventing stutters that could affect the 1% lows.

The CPU's memory bandwidth of 51.2 GB/s and its support for DDR4 memory are sufficient for this title. While the 5600's performance is not exceptional, it is clearly adequate. The benchmark results show that it sits close to rivals like the Intel Core Ultra 7 258V and the AMD Ryzen 5 8500G, with an average benchmark score of 20,468. This suggests that a more powerful CPU would yield diminishing returns in Thief, as the GPU would still be the limiting factor at most settings and resolutions. The CPU's role is to maintain a stable frame delivery, which it does effectively.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600 and the Intel Arc B570 ranks 2,296 out of 2,851 tested combos for Thief. This places it in the bottom 20% of all configurations, which is a direct result of the GPU's performance ceiling in this specific title. The rank is a holistic measure that considers the combined capabilities of both components. While the CPU is a competent performer, the GPU's measured data pulls the combo's ranking down.

The GPU, Intel Arc B570, has an average benchmark score of 20,556 and sits in the 65th percentile of all GPUs. Its performance is very close to the NVIDIA GeForce RTX 3070 Mobile, with a deltaPct of 0.1% higher, and the Intel Arc A750, which is 0.1% faster. This positions it as a mid-range graphics card. In Thief, however, its performance at higher resolutions is below what its synthetic scores might suggest. The 4K scores, which are all below 55 FPS, contribute to the low combo ranking.

The low rank is not necessarily an indictment of poor performance but rather a reflection of the game's demands. The combo excels at 1080p, where its rank would be significantly better than at 4K. The overall rank of 2,296 is a weighted average that accounts for all tested resolutions and settings. For a user with a 1080p monitor, this combo would provide a very good experience, but for 4K enthusiasts, it would be a poor choice. The data suggests that this combo is best suited for 1080p or 1440p gaming, where it can deliver playable frame rates at moderate to high settings.

GPU Role

The Intel Arc B570 is the primary determinant of performance in this configuration, especially as resolution increases. The GPU is built on the Xe2-HPG architecture (Battlemage) and features 2,304 shading units, 144 TMUs, and 80 ROPs. It has a boost clock of 2500 MHz and is equipped with 10 GB of GDDR6 memory on a 160-bit bus, providing a bandwidth of 380.0 GB/s. These specifications position it as a capable 1080p and 1440p card, which is consistent with the measured results.

The GPU's performance in Thief shows a clear processing limit at higher resolutions. The pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s are taxed heavily at 4K, as evidenced by the sub-60 FPS averages. The 10 GB VRAM buffer, while adequate for this title, is not the bottleneck; the raw compute throughput of 11.52 TFLOPS is the limiting factor. The data shows a significant drop-off in performance when moving from 1440p to 4K, indicating that the GPU's fillrate and shading capacity are insufficient for the increased pixel count.

The B570's closest performance rival, according to benchmark scores, is the Intel Arc A750, which is 0.1% faster. This suggests that the B570 is a slight refinement over its predecessor in the Alchemist series. In Thief, the GPU behaves as expected for its class: it provides excellent frame rates at 1080p, good frame rates at 1440p with settings adjustments, and playable but not ideal frame rates at 4K. The data confirms that the GPU is the component that users should focus on when upgrading for higher resolutions in this game.
