Thief

The AMD Ryzen 5 5600F paired with the Intel Arc B390 produces a distinctive performance profile in Thief, a 2014 stealth title that remains demanding under modern scrutiny. The data shows a system that is playable at lower resolutions and settings, but one that becomes progressively constrained as graphical load increases. This analysis breaks down the measured FPS results, the roles of the CPU and GPU, and how this specific combination ranks against other tested configurations.

Resolution Scaling

The measured FPS data across the three tested resolutions reveals a clear and consistent pattern: performance is heavily dictated by resolution, with the most significant drop occurring between 1440p and 4K. At 1080p with Low settings, the combo achieves an average of 86 FPS. Moving to 1440p at the same Low settings yields 59 FPS, a substantial 31.4% reduction. The step to 4K at Low settings brings the average down to 35 FPS, a further 40.7% reduction from the 1440p figure. This scaling behavior indicates that the rendering pipeline is becoming saturated with pixel workload.

The trend is consistent across all settings presets. At High settings, the average FPS drops from 50 at 1080p to 34 at 1440p (a 32% decrease), and then to 20 at 4K (a 41.2% decrease from 1440p). The Medium preset shows a similar trajectory: 66 FPS at 1080p, 45 FPS at 1440p, and 26 FPS at 4K. Even the Ultra preset, which is the most demanding, follows the same pattern with averages of 48, 33, and 19 FPS at 1080p, 1440p, and 4K, respectively.

What does this scaling tell us about the limiting component? The fact that the FPS drops by roughly a third when moving from 1080p to 1440p, and then by another 40% when moving to 4K, suggests a strong dependence on the pixel fill rate and memory bandwidth. The Intel Arc B390 is an integrated graphics processor (IGP) with a memory interface described as "System Shared," and its memory bandwidth is "System Dependent." This means the GPU is relying on the system's main memory for its framebuffer, which is a classic bottleneck at higher resolutions where the amount of data being written to and read from memory increases dramatically.

The GPU's pixel rate is listed as 60.00 GPixel/s, and while that number is not directly comparable to the measured FPS, the scaling pattern strongly implies that the GPU is the primary limiting factor at 1440p and 4K. The CPU, on the other hand, appears to be providing sufficient headroom, as the performance degradation aligns closely with the increase in pixel count. The system moves from a playable 86 FPS at 1080p Low to a barely interactive 19 FPS at 4K Ultra, a 78% total drop, which is characteristic of a GPU that is overburdened by resolution.

GPU Role

The Intel Arc B390 is the clear performance ceiling for this combination. Its benchmark data shows a single 3DMark Steel Nomad DX12 score of 1482, placing it in the 9th percentile of all GPUs. This is a very low standing, and the nearest rivals in the database are the NVIDIA GeForce GT 520MX (with an average score of 1463, a delta of 1.3%), the GeForce 800M (1460, 1.5%), and the GeForce GT 625 OEM (1446, 2.5%). The Arc B390 is only 2.7% ahead of the GeForce GT 710 (1443). These comparisons place the B390 in the entry-level, or even legacy, performance tier.

This low raw performance is reflected in the actual game results. The GPU's architecture is Xe3-LPG, built on a 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 render output units. It also has 12 ray tracing cores. The base clock is 300 MHz, with a boost clock of 2500 MHz. However, the most critical specification for this analysis is the memory: it is "System Shared," meaning there is no dedicated VRAM. The bus width is also "System Shared," and the bandwidth is "System Dependent." In Thief, this lack of dedicated memory is likely a major factor in the poor performance at higher resolutions, as the GPU must compete with the CPU for memory access.

The measured FPS data corroborates the benchmark score. At 4K Ultra, the average FPS is just 19, which is effectively unplayable. Even at 1080p Ultra, the average is only 48 FPS. The GPU's texture rate is 120.0 GTexel/s and its FP32 throughput is 7.680 TFLOPS, but these theoretical figures do not translate into smooth gameplay. The data shows that the Arc B390 is a component that can handle Thief at low to medium settings and at 1080p, but it struggles to maintain fluid frame rates as the resolution and detail levels increase. The system's performance is fundamentally bound by this IGP's limited processing and memory resources.

Measured FPS Breakdown

The measured data provides a complete matrix of performance across three resolutions and four settings. The following breakdown details every recorded data point.

At 1920x1080, the system performs at its best. With Low settings, the average FPS is 86. The Medium setting yields an average of 66 FPS, with a recorded minimum of 56 and a maximum of 75 FPS. On High settings, the average drops to 50 FPS. The Ultra preset produces an average of 48 FPS. This shows a linear progression where each step up in quality costs a significant number of frames.

At 2560x1440, performance falls into a less comfortable range. The Low setting average is 59 FPS. The Medium setting average is 45 FPS, with a minimum of 38 and a maximum of 52 FPS. The High setting average is 34 FPS, and the Ultra setting average is 33 FPS. The gap between Low and Medium is 14 FPS, while the gap between Medium and High is 11 FPS. The difference between High and Ultra is minimal at just 1 FPS.

At 3840x2160, the system is largely overwhelmed. The Low setting average is 35 FPS. The Medium setting average is 26 FPS, with a minimum of 22 and a maximum of 30 FPS. The High setting average is 20 FPS, and the Ultra setting average is 19 FPS. At this resolution, even the most aggressive quality reduction cannot bring the frame rate into a playable range, with the difference between High and Ultra being a negligible 1 FPS.

The data reveals that the most significant performance gains come from resolution scaling rather than settings scaling. For example, moving from 1080p Ultra (48 FPS) to 1440p Low (59 FPS) actually results in a higher frame rate, despite the increase in resolution, because the graphical load is reduced. Conversely, moving from 1440p Low (59 FPS) to 1080p Ultra (48 FPS) yields a lower frame rate. This suggests that lowering the resolution is a more effective strategy for improving performance than lowering the in-game quality settings.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Thief, the AMD Ryzen 5 5600F and Intel Arc B390 pairing occupies a very low position. It holds a combo rank of 2534 out of 2851 total combos. This places it in the bottom 11.1% of all systems tested, indicating that it is a low-performance configuration overall.

This ranking is primarily driven by the GPU's poor showing. The Arc B390's 9th percentile standing in the GPU benchmarks is a strong indicator of its limited capabilities. The CPU, on the other hand, performs much better. The Ryzen 5 5600F has an average benchmark score of 36945, placing it in the 85th percentile of all CPUs. Its nearest rivals include the Intel Core Ultra 5 225 (average score 36938, delta 0%), the AMD Ryzen 5 5500X3D (37018, -0.2%), and the AMD Ryzen AI 7 PRO 450 (37093, -0.4%).

The stark contrast between the CPU's high percentile (85th) and the GPU's low percentile (9th) creates a significant bottleneck. The CPU is capable of feeding data much faster than the GPU can process it. In Thief, this imbalance is apparent in the resolution scaling, where the GPU's inability to handle pixel throughput becomes the limiting factor. The system's overall rank of 2534rd is a reflection of this imbalance, showing that the combination is held back by its weakest link. The data suggests that this processor would pair much more effectively with a more powerful discrete graphics card, but as configured, the system's performance is firmly in the entry-level tier.

CPU Role

The AMD Ryzen 5 5600F is a 6-core, 12-thread processor based on the Zen 3 architecture. It has a base clock of 3.00 GHz and a boost clock of 4.00 GHz. The CPU's benchmark scores are robust, with a single-thread score of 2872 and a multi-thread score of 19236. Its average benchmark score of 36945 places it in the 85th percentile of all CPUs, showing that it is a capable mid-range processor.

In Thief, the CPU's role appears to be largely supportive. Given the game's 2014 release date, it is unlikely to be heavily multi-threaded, but the Ryzen 5 5600F's 12 threads provide ample processing headroom. The measured FPS data shows that performance scales almost exclusively with resolution and graphics settings, not with CPU-bound factors. If the CPU were the limiting component, we would expect to see a plateau in FPS at lower resolutions where the GPU is less stressed. However, the data shows a clear increase from 48 FPS at 1080p Ultra to 86 FPS at 1080p Low, indicating that the GPU is the primary bottleneck even at the lowest resolution.

The CPU's memory support is DDR4 with a dual-channel bus and a bandwidth of 51.2 GB/s. This memory bandwidth is likely sufficient for the game at 1080p, but the "System Dependent" bandwidth of the GPU's shared memory architecture means that the CPU and GPU are competing for the same memory resources. This could introduce stuttering or frame drops in memory-intensive scenes, though the measured data for Medium settings shows a relatively stable range (e.g., 56-75 FPS at 1080p). The CPU's high percentile ranking versus the GPU's low ranking suggests that the processor is not the cause of the low frame rates; rather, it is waiting on the GPU to complete its rendering tasks.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this system depends heavily on the user's target resolution and tolerance for frame rate fluctuations.

For 1080p, the best balance of visual quality and performance is the Medium preset. It delivers an average of 66 FPS, with a minimum of 56 FPS and a maximum of 75 FPS. This is the highest settings level that maintains an average above 60 FPS, which is generally considered the threshold for smooth gameplay. The High preset drops to 50 FPS, which is playable but not as fluid. The Ultra preset offers no significant advantage over High (48 vs 50 FPS) and is not worth the performance cost.

For 1440p, the only playable option is the Low preset, which yields an average of 59 FPS. This is just below the 60 FPS target but is still acceptable. The Medium preset at 45 FPS is noticeably less smooth, and the High and Ultra presets (34 and 33 FPS, respectively) are too sluggish for a stealth game that requires precise timing. If a user is locked to 1440p, they should accept the Low settings as the standard.

At 4K, the data indicates that this system is not suited for gameplay. The best average is 35 FPS at Low settings, which is below the playable threshold. The Medium, High, and Ultra presets (26, 20, and 19 FPS) are all effectively unplayable.

The overall recommendation is to play Thief at 1920x1080 with the Medium preset. This configuration provides the highest visual fidelity while maintaining an average FPS above 60. Users who prioritize frame rate above all else could drop to Low settings at 1080p for a very smooth 86 FPS, but the Medium preset offers a more balanced experience. The data clearly shows that pushing this system beyond 1080p, or beyond Medium settings, results in a significant degradation of playability.
