Thief

Thief, a 2014 stealth title, is not a demanding game by modern standards, but the data shows that the AMD Ryzen 9 5900X and Intel Arc B370 combination requires careful settings management to achieve a playable experience, particularly at higher resolutions. The benchmark results indicate a system that is heavily constrained by the graphics processor, as the Arc B370's performance profile severely limits frame rates in almost every configuration tested. The following analysis breaks down the measured performance to provide practical guidance for configuring the game.

Settings Recommendations

The most critical takeaway from the measured FPS data is that the Ultra preset is effectively unusable across all resolutions, and the High preset is only viable at 1080p. The data shows that the Ultra preset yields an average of 43 FPS at 1920x1080, which is below the threshold for a smooth experience, and this figure drops to a nearly unplayable 17 FPS at 3840x2160. The High preset is more promising, but only at 1080p, where it achieves 45 FPS. At 1440p, High drops to 31 FPS, and at 4K, it falls to 18 FPS.

For the best experience, the Medium preset at 1920x1080 is the clear recommendation. The measured data shows an average of 59 FPS at this setting, with a minimum of 50 FPS and a maximum of 68 FPS. This is the only configuration that consistently stays above the 60 FPS target without dipping into the 40s, providing a stable and responsive gameplay experience. While the Low preset at 1080p is faster at 78 FPS, the visual quality sacrifice is significant, and the Medium preset offers a much better balance.

If you are playing at 2560x1440, the Medium preset is still the best option, but you will have to accept a lower frame rate. The data shows an average of 41 FPS at this resolution, which is playable but not ideal for fast-paced action. The Low preset at 1440p is the only other viable option, achieving 53 FPS, but again, this comes with a substantial visual downgrade. For 4K, the data suggests that even the Low preset at 31 FPS is not a comfortable experience, so users with a 4K display should strongly consider running the game at a lower resolution.

Ultimately, the analysis points to a simple rule: prioritize the Medium preset. It offers the most consistent frame pacing and the best compromise between visual fidelity and performance for this specific hardware combination. The difference between Medium and High is a consistent 14 FPS drop at 1080p, which is a steep price for the marginal visual improvements in a game from 2014.

FAQ

Q: What is the best settings preset for playing Thief at 1080p with this hardware?

A: The Medium preset at 1920x1080 provides the best experience, with a measured average of 59 FPS (minimum 50, maximum 68). The Low preset is faster at 78 FPS, but the Medium preset offers a significantly better visual experience while remaining comfortably playable. The High preset at 45 FPS is noticeably less smooth.

Q: Can this system handle Thief at 4K resolution?

A: No, not playably. The data shows that at 3840x2160, the best average FPS is 31 on the Low preset. The Medium preset drops to 24 FPS, and the High and Ultra presets are at 18 FPS and 17 FPS respectively. All of these are below the acceptable threshold for smooth gameplay.

Q: How much of a performance difference is there between the Low and Ultra presets?

A: The difference is substantial. At 1080p, the Low preset achieves an average of 78 FPS, while the Ultra preset only manages 43 FPS. This represents a 35 FPS drop, or roughly a 45% reduction in frame rate, for the highest visual quality settings.

Q: Is the frame rate more stable at lower resolutions?

A: Yes, the data indicates this. At 1080p on Medium, the minimum FPS is 50 and the maximum is 68, a range of 18 FPS. At 1440p on Medium, the range is 12 FPS (35 to 47), but the average is lower. At 4K, the range narrows further, but the frame rates are too low to be useful.

Q: Which component is the bottleneck for this game?

A: The GPU is the primary bottleneck. The Intel Arc B370's benchmark scores are extremely low, placing it in the 5th percentile of all GPUs. Its performance is comparable to much older cards like the ATI Radeon HD 5770, which is insufficient for modern resolutions and settings in Thief. The CPU is not the limiting factor.

Q: What is the expected performance of the CPU in this system?

A: The AMD Ryzen 9 5900X is a high-end processor, ranking in the 87th percentile of all CPUs. Its benchmark scores are excellent, with a Cinebench R23 multi-core score of 16262 and a single-core score of 1527. It is not a performance constraint for this title.

GPU Role

The Intel Arc B370 is the decisive factor in this system's Thief performance. The data shows a GPU with a 3DMark Steel Nomad DX12 score of only 1184, placing it in the 5th percentile of all GPUs. This score is remarkably low, and the nearest rivals are all legacy parts like the ATI Radeon HD 5770 (score 1190) and the AMD Radeon HD 7650M (score 1192). This places the Arc B370 firmly in the entry-level category, with performance that is not suited for high-fidelity gaming.

The GPU's specifications support this conclusion. It has a base clock of 300 MHz and a boost clock of 2400 MHz, but its memory configuration is "System Shared." This means it relies on the system's main memory for its frame buffer, which is a significant disadvantage. The memory bandwidth is listed as "System Dependent," which means it is limited by the CPU's memory support, in this case, the Ryzen 9 5900X's dual-channel DDR4 setup with a bandwidth of 51.2 GB/s. This is far slower than a dedicated graphics card's VRAM.

The combination of low raw compute power (6.144 TFLOPS FP32) and shared system memory results in the poor frame rates seen in the measurements. The GPU is simply overwhelmed by the graphical demands of Thief at higher settings and resolutions. The data shows that the difference between Low and Ultra presets is around 35 FPS at 1080p, which is a direct consequence of the GPU's limited shading units (1280) and texture mapping units (40). The 20 ROPs are also a constraint, limiting the pixel fill rate to just 48.00 GPixel/s, which is insufficient for modern resolutions.

Measured FPS Breakdown

The measured data provides a clear picture of the system's performance envelope. At 1920x1080, the frame rates range from a low of 43 FPS on Ultra to a high of 78 FPS on Low. The Medium preset is the most balanced, with an average of 59 FPS and a tight range between 50 and 68 FPS. The High preset is a step down, averaging 45 FPS.

At 2560x1440, all presets take a significant hit. The Low preset is the only one that remains over 50 FPS, with an average of 53 FPS. The Medium preset drops to 41 FPS, with a range of 35 to 47 FPS. High and Ultra average 31 FPS and 29 FPS respectively, which is a marginal difference and indicates that the GPU is fully saturated.

At 3840x2160, the situation becomes dire. The Low preset is the "best" performer, with an average of 31 FPS. Medium averages 24 FPS, with a minimum of 20 FPS and a maximum of 27 FPS. High and Ultra are nearly identical at 18 FPS and 17 FPS, respectively. This demonstrates that the GPU is completely unable to handle the pixel count at 4K, and the frame rate collapses to a slideshow.

The data pattern is consistent: the delta between presets shrinks as resolution increases. At 1080p, the gap between Low and Ultra is 35 FPS. At 1440p, it narrows to 24 FPS. At 4K, it is only 14 FPS. This is a classic sign of a GPU-limited scenario, where the processor is no longer the bottleneck, and the graphics card is working at its absolute maximum capacity regardless of the settings.

Resolution Scaling

The frame rate scaling from 1080p to 4K confirms that the GPU is the sole limiting factor. Moving from 1920x1080 to 2560x1440 on the Medium preset reduces the average FPS from 59 to 41, a drop of 18 FPS (approximately 30%). Moving further to 3840x2160 reduces the average to 24 FPS, another drop of 17 FPS (approximately 41%).

This scaling behavior is expected when a system is GPU-bound. The number of pixels rendered increases substantially with each resolution step, and the Arc B370 does not have the raw throughput to maintain its frame rate. The data for the Low preset shows a similar trend: 78 FPS at 1080p, 53 FPS at 1440p, and 31 FPS at 4K. The frame rate roughly halves from 1080p to 4K, which is a direct consequence of the fourfold increase in pixel count.

The implication is clear: the CPU is not a factor in this game's performance. The Ryzen 9 5900X is a high-end 12-core processor, but Thief is an older title that does not heavily utilize many cores. The benchmark data shows that the CPU is well ahead of its rivals, and its performance is not the reason for the low frame rates. The resolution scaling provides definitive evidence that to improve performance, the user must either lower the resolution or the settings, as the GPU is the bottleneck in every scenario.

CPU Role

The AMD Ryzen 9 5900X is an exceptionally powerful processor that is completely underutilized by this workload. With 12 cores and 24 threads, based on the Zen 3 architecture, it is a multi-threaded powerhouse. Its benchmark scores are impressive, including a Cinebench R23 multi-core score of 16262 and a Geekbench multi-core score of 14118. It ranks in the 87th percentile of all CPUs, demonstrating that it is a top-tier part.

However, the game's performance is not determined by these metrics. The measured FPS data shows that the system is GPU-limited in all configurations. The CPU's role in this title is to feed the GPU with draw calls and game logic, and it does so without breaking a sweat. The single-threaded performance, as measured by a 3DMark single-thread score of 941 and a Geekbench single-core score of 2083, is more than sufficient for a game from 2014.

The data suggests that even a much weaker CPU would not improve the frame rates, as the GPU is the clear bottleneck. The Ryzen 9 5900X's high memory bandwidth (51.2 GB/s) and PCIe Gen 4 support ensure that it can communicate with the system memory efficiently, but the shared memory architecture of the Arc B370 negates any potential advantage. In this specific combination, the CPU is not a performance constraint; it is a high-end component paired with a low-end GPU, resulting in a system where the GPU's limitations are the only thing that matters for Thief.
