Thief

The AMD Ryzen 9 5950X paired with the Intel Arc B570 produces a distinct performance profile in Thief, characterized by a significant gap between low and high graphical presets across all resolutions. The data shows a system that is clearly capable of high refresh rates at standard resolutions but encounters a hard ceiling at 4K Ultra, where playability becomes marginal. This analysis breaks down the measured frames per second (FPS) data to determine the optimal settings, the role of each component, and how this specific combination ranks against other tested systems.

Settings Recommendations

The benchmark data for Thief reveals a clear hierarchy of performance across its four presets. The primary goal is to identify the settings that offer the best balance between visual fidelity and smooth gameplay, using the measured average FPS as the primary guide.

At 1920x1080, the system demonstrates its full potential. The Ultra preset delivers an average of 73 FPS, which is entirely playable and represents the highest visual quality available. The High preset increases the average to 77 FPS, a marginal gain that does not justify the reduction in visual effects. The Medium preset jumps to 101 FPS, and Low reaches 133 FPS. For a game like Thief, where immersion and atmosphere are key, the Ultra preset at 1080p is the recommended choice, as it provides a smooth experience without compromising on the game's intended visual presentation.

Moving to 2560x1440, the performance cost of higher resolution becomes evident. The Ultra preset drops to an average of 50 FPS. While this is above the threshold for console-like playability, it is not ideal for a fast-paced stealth game where quick camera movements are common. The High preset offers a more solid 53 FPS. The Medium preset provides a more comfortable 69 FPS, and Low reaches 91 FPS. Here, the High preset represents the best compromise. It maintains a playable frame rate that is close to the Ultra experience but with fewer demands on the hardware, ensuring a more consistent performance in demanding scenes. The 3 FPS difference between High and Ultra is not worth the potential for dips below 50 FPS.

At 3840x2160, the system is heavily taxed. The Ultra preset averages only 29 FPS, which is below the standard for smooth gameplay and will likely feel stuttery. The High preset is only marginally better at 31 FPS. The Medium preset, with an average of 41 FPS and a minimum of 35 FPS, becomes the first viable option for 4K. The Low preset is the only one to achieve a solidly playable frame rate, with an average of 54 FPS. Given that the visual jump from Low to Medium is significant, and the frame rate is more stable, the Medium preset is the recommended choice for 4K. It is the highest quality setting that consistently stays above the 30 FPS minimum, offering a playable, though not silky-smooth, experience. The data shows that the Low preset is the only way to get a truly fluid 60 FPS-class experience at this resolution, but the visual sacrifices are substantial.

FAQ

Q: What is the maximum average frame rate this system can achieve in Thief?

A: The highest average frame rate measured is 133 FPS, which is achieved at the 1920x1080 resolution with the Low settings preset.

Q: Is the Intel Arc B570 capable of running Thief at 4K resolution?

A: Yes, but with limitations. At 4K with Medium settings, the system achieves an average of 41 FPS. The Low preset is required for a more comfortable 54 FPS average. The High and Ultra presets fall below 31 FPS, which is not ideal for smooth gameplay.

Q: How much performance is lost when moving from 1080p to 4K at the High preset?

A: At the High preset, the average frame rate drops from 77 FPS at 1920x1080 to 53 FPS at 2560x1440, and finally to 31 FPS at 3840x2160. This represents a 60% reduction in average FPS from 1080p to 4K.

Q: Which component is more likely to be the bottleneck at 4K Ultra settings?

A: The data suggests the GPU is the limiting factor. The frame rate at 4K Ultra is 29 FPS, which is very low. The CPU, with its high multi-threaded performance, is unlikely to be the primary constraint at such a high resolution and graphical load. The GPU is being saturated.

Q: How does the Ryzen 9 5950X's single-thread performance relate to the frame rates seen at 1080p?

A: The Ryzen 9 5950X has a strong single-thread score of 944 in 3dmark_single_thread and 1614 in cinebench_r23_singlecore. This robust single-core capability helps ensure that the CPU does not bottleneck the GPU at lower resolutions like 1080p, where the GPU can render frames very quickly and the CPU must keep up with the game's logic and draw calls.

Q: What is the frame time consistency like at 1440p Medium settings?

A: The data provides a min and max FPS for this setting: an average of 69 FPS with a minimum of 59 and a maximum of 79. This indicates a relatively consistent frame delivery, with the minimum staying well within a playable range.

Resolution Scaling

The measured FPS data across 1080p, 1440p, and 4K resolutions provides insight into the scaling behavior of this hardware combination in Thief. The performance drop is not linear, and the pattern reveals the system's balance point.

At the Low preset, the frame rates are 133 FPS at 1080p, 91 FPS at 1440p, and 54 FPS at 4K. This shows a clear and substantial impact from increasing pixel count. The drop from 1080p to 1440p is a 32% reduction, while the drop from 1440p to 4K is a 41% reduction. The scaling is severe at this preset because the GPU is not heavily burdened by visual effects, so the raw pixel fill rate becomes the dominant factor.

At the High preset, the average FPS drops from 77 at 1080p to 53 at 1440p (a 31% reduction) and then to 31 at 4K (a 42% reduction from 1440p). This pattern is similar to the Low preset, indicating that the GPU is still the primary bottleneck. The frame rate is being dictated by the number of pixels being rendered.

The Ultra preset shows a similar trend but at lower absolute values: 73 FPS at 1080p, 50 FPS at 1440p, and a nearly unplayable 29 FPS at 4K. The consistent ~30-40% performance penalty for each resolution step up points to a system that is heavily dependent on the GPU's fill rate and memory bandwidth. The Intel Arc B570, with its 10 GB of GDDR6 memory on a 160-bit bus, appears to be the constraining factor as resolution increases.

The data strongly suggests that the GPU is the limiting component in this configuration. The CPU, with its high core count and strong performance metrics, is not the bottleneck. The steep declines in FPS that mirror the increase in pixel count are a classic sign of a GPU-bound scenario. For players wanting to use this combo, the resolution scaling means that 1080p is the sweet spot for high refresh rates, 1440p is viable for a high-quality experience, and 4K is only feasible at lower graphical presets.

Measured FPS Breakdown

The following is a detailed breakdown of the measured average FPS, and where available, minimum and maximum FPS, for each resolution and settings combination.

1920x1080

• Low: Average FPS is 133.
• Medium: Average FPS is 101, with a minimum of 86 and a maximum of 116.
• High: Average FPS is 77.
• Ultra: Average FPS is 73.

At 1080p, the system is clearly CPU-bound at lower settings, as the frame rate scales dramatically from Low to Medium. The gap between High and Ultra is minimal, only 4 FPS, suggesting that the Ultra preset's additional effects are not particularly taxing on the GPU at this resolution.

2560x1440

• Low: Average FPS is 91.
• Medium: Average FPS is 69, with a minimum of 59 and a maximum of 79.
• High: Average FPS is 53.
• Ultra: Average FPS is 50.

At 1440p, the GPU begins to take on a more significant role. The frame rate differences become more compressed between presets, indicating that the GPU is starting to become the primary limiting factor. The 19 FPS difference between Low and Ultra is much smaller than at 1080p.

3840x2160

• Low: Average FPS is 54.
• Medium: Average FPS is 41, with a minimum of 35 and a maximum of 47.
• High: Average FPS is 31.
• Ultra: Average FPS is 29.

At 4K, the GPU is heavily saturated. The difference between High and Ultra is just 2 FPS, confirming that the system is entirely GPU-limited. Even the Low preset, which produces 54 FPS, cannot maintain a steady 60 FPS, highlighting the immense demand of 4K rendering. The Medium preset's minimum of 35 FPS is concerning for consistent smoothness.

How This Combo Ranks

In the database of tested combinations, the AMD Ryzen 9 5950X and Intel Arc B570 pairing ranks 2296 out of 2851 for Thief. This places it in the bottom 20% of all tested systems for this specific game.

This ranking is notably low, despite the individual components having respectable average benchmark scores. The CPU has an average benchmark score of 51947, which is in the 91st percentile of all CPUs. The GPU's average benchmark score is 20556, placing it in the 65th percentile of all GPUs. The low in-game rank suggests that Thief's specific engine and workload do not favor this combination as much as other games might.

The CPU's nearest rival, the Intel Core Ultra 5 235HX, has an average score that is 0.2% higher. The Intel Core i9-13900F is 0.4% lower. These are very close scores. The GPU's nearest rivals include the Intel Arc A750, which is 0.1% lower, and the NVIDIA GeForce RTX 3070 Mobile, which is 0.1% higher. Again, the performance is very close to these parts.

The discrepancy between the high benchmark percentiles and the low in-game rank indicates that Thief is not a title that scales well with the strengths of this particular hardware. The game, released in 2014, likely has a rendering path that does not fully utilize the advanced features or driver optimizations of the newer Intel Arc architecture. The result is a system that performs well in synthetic benchmarks but underperforms relative to its peers in this specific title, landing in the 2296th position.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture. It has a base clock of 3.40 GHz and a boost clock of 4.90 GHz. In Thief, the CPU's role is to handle game logic, physics, and draw calls, feeding the GPU with data.

The benchmark data shows that the 5950X has impressive multi-threaded capabilities, with a Cinebench R23 multi-core score of 26017 and a 3dmark_max_threads score of 11597. However, Thief is a game from 2014 that is unlikely to use all 16 cores effectively. More important for gaming is the single-thread performance. The 5950X scores 944 in the 3dmark_single_thread test and 1614 in Cinebench R23 single-core. These are strong numbers, indicating that the CPU can handle the game's primary thread effectively.

The evidence for the CPU not being a bottleneck is clear in the resolution scaling. At 1080p Low, the system hits 133 FPS. If the CPU were a major limiting factor, we would not see such a high frame rate. As resolution increases, the frame rate drops significantly, which is the signature of a GPU bottleneck. The CPU is providing enough performance headroom to allow the GPU to be the limiting factor at all resolutions and settings tested. The 5950X's high clock speeds and robust per-core performance ensure that it can keep up with the Arc B570, even at lower resolutions where the GPU demands data at a very fast pace.

GPU Role

The Intel Arc B570 is a graphics card based on the Xe2-HPG architecture, manufactured on a 5 nm process. It features 10 GB of GDDR6 memory on a 160-bit bus, providing 380.0 GB/s of memory bandwidth. Its base and boost clocks are both 2500 MHz. The GPU's performance in synthetic tests is solid, with a Passmark G3D score of 14195 and a Geekbench Vulkan score of 96844.

In Thief, the GPU is the primary determinant of performance, especially at higher resolutions and settings. The data shows a clear pattern of frame rate being directly tied to the graphical load. At 1080p Medium, the GPU produces 101 FPS. At 1440p Medium, it produces 69 FPS, and at 4K Medium, it produces 41 FPS. This scaling is consistent with a GPU that is being progressively more saturated.

The 10 GB VRAM buffer is likely sufficient for Thief at these settings, as the game is not known for being excessively memory-hungry. The bottleneck appears to be the raw compute and fill rate of the GPU, as well as its memory bandwidth. The 160-bit bus and 380.0 GB/s bandwidth are modest figures, and they are likely a limiting factor at 4K resolution. The 29 FPS at 4K Ultra shows that the GPU is completely overwhelmed. The data indicates that the Arc B570 is a capable mid-range card, but Thief at 4K Ultra is beyond its capabilities. Its performance is best suited for 1080p and 1440p gaming, where it can provide a good balance of visual quality and frame rate.
