Thief

The AMD Ryzen 5 5600X paired with the Intel Arc B570 presents a compelling mid-range analysis for the 2014 stealth classic, Thief. The benchmark data reveals a system that is heavily influenced by resolution, with the GPU becoming the primary bottleneck as pixel count increases. This combination ranks 2296th out of 2851 tested combos in this game, placing it in the lower half of the database, which suggests that while it is capable, it is not a top-tier pairing for this title.

Resolution Scaling

The transition from 1080p to 4K dramatically alters the performance profile of this combo. At 1920x1080 with Low settings, the system achieves an average of 133 FPS, which is a very playable frame rate. Moving up to 2560x1440 at the same Low preset, the average drops to 91 FPS, a 31.6% reduction from the 1080p figure. This scaling is significant and points to the GPU starting to feel the load, though the CPU is still likely feeding frames adequately.

The most telling shift occurs when pushing to 3840x2160. At 4K with Low settings, the average FPS plummets to 54, which is a 40.7% drop from the 1440p result. This steep decline indicates that the Intel Arc B570 is now the definitive limiting factor. The data suggests that the Ryzen 5 5600X, with its 6 cores and 12 threads, is capable of handling the game's logic at these lower resolutions, but the GPU's fill rate and memory bandwidth are insufficient to keep up with the massive pixel count at 4K.

This pattern is consistent across all settings. For High settings, the average FPS goes from 77 at 1080p to 53 at 1440p (a 31.2% drop), then to 31 at 4K (a 41.5% drop from 1440p). The scaling factor between 1440p and 4K remains remarkably consistent, hovering around a 40% performance loss. This consistency is a classic sign of a pixel-bound scenario where the GPU's compute units are saturated. The CPU is not the limiting factor here; if it were, we would see a more significant drop in performance at lower resolutions where the GPU is not the bottleneck.

The implication is clear: for smooth 4K gameplay, this combo is not viable. The 4K results, ranging from 29 FPS at Ultra to 54 FPS at Low, are all below the generally accepted 60 FPS threshold for fluid gameplay. This questions the utility of this pairing for high-resolution displays, suggesting it is better suited for 1080p or 1440p gaming, where it can deliver a much more satisfying experience.

GPU Role

The Intel Arc B570, based on the Xe2-HPG architecture, is the dominant component in determining this game's performance, especially at higher resolutions. Its 10 GB of GDDR6 memory on a 160-bit bus provides a memory bandwidth of 380.0 GB/s. This bandwidth is a critical factor for a game like Thief, which features detailed textures and complex lighting. At 4K, the higher memory pressure likely contributes to the significant frame rate drop, as the GPU struggles to feed its shading units with enough texture data.

The GPU's core configuration includes 2304 shading units, 144 texture mapping units, and 80 render output units. These specs, combined with a base and boost clock of 2500 MHz, deliver a pixel rate of 200.0 GPixel/s and a texture rate of 360.0 GTexel/s. The 4K Ultra setting, which demands the highest texture and shading work, yields an average of just 29 FPS. This is a clear indicator that the GPU's raw compute power is insufficient for the highest fidelity at this resolution.

The Arc B570's performance in synthetic benchmarks shows a moderate position, with a percentile of 65 versus all GPUs. Its average benchmark score of 20556 places it near the NVIDIA GeForce RTX 3070 Mobile, which has a deltaPct of 0.1. This suggests that in general compute tasks, the B570 performs similarly to that mobile GPU, but its specific driver and architecture optimization for older games like Thief is what matters here. The data shows that the GPU's role transitions from being a capable performer at 1080p to a severe bottleneck at 4K.

The scaling from Medium to High settings also illustrates the GPU's limitations. At 1440p, Medium averages 69 FPS, while High averages 53 FPS, a 23.2% drop. At 4K, this drop is from 41 FPS to 31 FPS, a 24.4% reduction. This proportional decrease suggests that the extra shading and texture detail from High settings uniformly tax the GPU, regardless of resolution. The GPU is clearly the primary driver of frame rate, and its 10 GB VRAM capacity, while adequate for 1080p, may not be sufficient to hold all the necessary assets for a effortless 4K experience without stuttering.

CPU Role

The AMD Ryzen 5 5600X, with its 6 cores and 12 threads based on the Zen 3 architecture, plays a supporting role in this pairing. Its base clock of 3.70 GHz and boost clock of 4.60 GHz provide strong single-threaded performance, which is crucial for a game like Thief that relies heavily on game logic and AI. In the benchmark data, the CPU's role is most evident at lower resolutions where the GPU is not fully saturated.

At 1080p with Low settings, the average FPS is 133. This high frame rate indicates that the CPU is capable of processing the game's data far faster than the GPU can render it. The CPU is not the limiting factor here. However, as the resolution increases, the gap between CPU and GPU performance narrows, and the CPU's influence on the final frame rate diminishes. The consistent ~30% drop in FPS from 1080p to 1440p across all settings is a direct result of the GPU's increased workload, not a CPU limitation.

The CPU's synthetic benchmark scores support its capability. Its 3dmark_max_threads score of 5588 and cinebench_r23_multicore score of 11838 show a solid multi-threaded performance. Its single-threaded performance, with a 3dmark_single_thread score of 917 and a cinebench_r23_singlecore score of 1541, is strong. This suggests that the Ryzen 5 5600X is more than adequate for Thief's CPU demands. The data indicates that this CPU will not bottleneck the Arc B570 in this title, particularly at 1080p, but its performance headroom becomes irrelevant as the GPU's pixel throughput becomes the deciding factor.

The CPU's percentile versus all CPUs is 75, placing it in the top quarter of processors. Its nearest rival, the AMD Ryzen 7 4800H, has a deltaPct of 0.1, showing that the 5600X is statistically tied with that mobile processor in average benchmark score. This confirms that the CPU is a strong performer, but its impact on this game's frame rates is secondary to the GPU. The data suggests that a user with a more powerful GPU would see higher FPS in this game, but the CPU would not be the reason for a performance ceiling.

Looking at the CPU's rivals, the AMD Ryzen 7 4800H has an average score very close to the 5600X (deltaPct of 0.1), suggesting that a system with that CPU and a different GPU could perform very differently in this game. The GPU's rival, the Intel Arc A750, also has a near-identical average score (deltaPct of -0.1), but the B570's performance in Thief is what is being measured here. The low combo rank highlights that the interaction between these two specific components in this game is not a strong one.

Measured FPS Breakdown

The following is a detailed breakdown of the measured average FPS for the AMD Ryzen 5 5600X and Intel Arc B570 in Thief, across all tested resolutions and settings.

At 1920x1080, the results show a clear hierarchy based on settings. Low settings yield the highest average at 133 FPS. Medium settings average 101 FPS, with a minimum of 86 FPS and a maximum of 116 FPS. High settings average 77 FPS. Ultra settings average 73 FPS. This shows that even at the lowest resolution, there is a 60 FPS difference between the lowest and highest quality presets, indicating the game is graphically demanding.

Moving to 2560x1440, the performance drops are consistent. Low settings average 91 FPS. Medium settings average 69 FPS, with a minimum of 59 FPS and a maximum of 79 FPS. High settings average 53 FPS. Ultra settings average 50 FPS. At this resolution, only the Low and Medium presets provide an average above 60 FPS, suggesting that users will need to compromise on visual quality to achieve smooth gameplay.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings average 54 FPS. Medium settings average 41 FPS, with a minimum of 35 FPS and a maximum of 47 FPS. High settings average 31 FPS. Ultra settings average 29 FPS. None of these results reach 60 FPS, confirming that 4K is not a viable option for this combo in Thief. The data shows a linear scaling of performance, with the Ultra preset being only marginally slower than High, suggesting that the GPU is completely saturated at this resolution.

Settings Recommendations

For the best experience in Thief with this hardware, the data strongly points towards 1920x1080 as the target resolution. At this resolution, the Medium preset offers an average of 101 FPS with a minimum of 86 FPS, which ensures a very smooth and responsive experience. This is the best balance between visual fidelity and performance, as it stays well above the 60 FPS threshold while still providing a significant upgrade in graphics quality over the Low preset.

If a user has a 1440p monitor, the options are more limited. The Medium preset at 2560x1440 averages 69 FPS, which is playable, but the minimum of 59 FPS means there will be occasional dips below 60 FPS. The Low preset averages 91 FPS, providing a much more comfortable margin, but with a significant reduction in visual quality. For a consistent experience, the Low preset at 1440p is the safer choice.

For users who prioritize visual fidelity above all else, the High or Ultra presets at 1080p are the only viable options that maintain an average above 70 FPS. Both 77 FPS and 73 FPS respectively are perfectly playable. The data suggests that using the High preset at 1080p is recommended for a more immersive experience without sacrificing performance. The 4K resolution should be avoided entirely, as even the Low preset fails to provide a consistently smooth experience, making the game feel unresponsive and visually stuttery.
