Thief

AMD Ryzen 9 9950X3D paired with the Intel Arc B390 produces a severely GPU-bound experience in Thief, with the measured frame rates indicating that the Arc B390 is the definitive bottleneck at every resolution and settings level tested. The data shows that this combination ranks in the bottom 11% of all tested combos for this game, making it a configuration suited only for 1080p Low settings if a playable frame rate is the priority.

Settings Recommendations

The benchmark data for this specific CPU-GPU pairing is unambiguous regarding the optimal settings preset: Low settings at 1920x1080 is the only configuration that delivers a consistently playable experience, with an average frame rate of 86 FPS. This is the single highest average FPS recorded across all twelve measured rows. The jump from Low to Medium at 1080p results in a substantial 20 FPS drop, bringing the average down to 66 FPS, which is still playable but sacrifices the headroom needed for demanding scenes.

At 1080p Medium, the measured minimum frame rate is 56 FPS, which provides a reasonable floor. However, the data suggests that High settings at 1080p, with an average of 50 FPS, is the boundary of acceptable performance. Pushing to Ultra at 1080p yields an average of 48 FPS, a marginal 2 FPS improvement over High, which is not a worthwhile trade for the extra visual fidelity. The performance delta between High and Ultra is negligible (2 FPS), indicating the GPU is saturated and the settings preset is no longer the primary factor.

For users prioritizing visual quality over frame rate, the data shows a hard limit. At 2560x1440, the Medium preset averages 45 FPS with a minimum of 38 FPS, which is borderline for a stealth title. The Ultra preset at 1440p drops to 33 FPS average, which is below the threshold for smooth gameplay. At 3840x2160, all presets are effectively unplayable, with the highest average being 35 FPS on Low settings. The optimal experience, based strictly on the measured rows, is definitively 1080p Low, as it is the only configuration that provides a substantial buffer above 60 FPS.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) with a 3 nm process node, and its role in this configuration is entirely defined by its limited computational resources. The benchmark data for the GPU shows a 3DMark Steel Nomad DX12 score of 1482, placing it in the 9th percentile of all GPUs. This score is critical for understanding the results, as it is the sole metric for the GPU's compute capability. The GPU's nearest rivals in that benchmark are the NVIDIA GeForce GT 520MX (scoring 1463, a 1.3% delta), the GeForce 800M (scoring 1460, a 1.5% delta), and the GeForce GT 625 OEM (scoring 1446, a 2.5% delta). These rivals are all entry-level or legacy mobile parts, confirming the Arc B390's position at the very bottom of the performance spectrum.

The GPU's clock speeds are listed as a base of 300 MHz and a boost of 2500 MHz, but these figures do not translate into meaningful gaming performance due to the system-shared memory architecture. The memory configuration is entirely "System Shared," meaning the GPU relies on the system's DDR5 RAM for both capacity and bandwidth. The memory bandwidth is listed as "System Dependent," which in practice creates a severe bottleneck in a game like Thief that requires consistent memory throughput. The GPU also has 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. The pixel rate is 60.00 GPixel/s and the texture rate is 120.0 GTexel/s, but these theoretical peak rates are unattainable in real-world scenarios due to the memory bottleneck.

The data indicates that the Arc B390 is the limiting component in this pairing. The Ryzen 9 9950X3D is a high-end desktop processor with 16 cores, 32 threads, and a boost clock of 5.70 GHz, and it is capable of far more than the GPU can deliver. The FPS results are consistently low even at 1080p, which is a classic symptom of GPU limitation rather than CPU limitation. The CPU's 3DMark scores (16,374 for 16 threads and 17,184 for max threads) are exceptionally high, but they are irrelevant to the gaming performance here because the GPU cannot process frames fast enough to utilize the CPU's throughput.

Resolution Scaling

The FPS scaling from 1080p to 4K confirms that the Intel Arc B390 is the definitive bottleneck. At Low settings, the average FPS drops from 86 at 1920x1080 to 59 at 2560x1440, a reduction of 27 FPS (a 31.4% decrease). Moving from 1440p to 4K at Low settings drops the average from 59 to 35 FPS, another 24 FPS reduction (a 40.7% decrease). This pattern shows that the GPU's performance degrades severely as resolution increases, which is expected for a component with system-shared memory and limited fill-rate capabilities.

The scaling behavior is consistent across all settings presets. At Medium settings, the average FPS is 66 at 1080p, 45 at 1440p, and 26 at 4K. The drop from 1080p to 1440p is 21 FPS, and the drop from 1440p to 4K is 19 FPS. For High settings, the progression is 50 FPS at 1080p, 34 FPS at 1440p, and 20 FPS at 4K. At Ultra settings, the averages are 48 FPS at 1080p, 33 FPS at 1440p, and 19 FPS at 4K. The data shows that the performance penalty for each resolution step is roughly consistent, indicating that the GPU's compute and memory subsystems are saturated at all settings.

The limiting component is clearly the GPU. If the CPU were the bottleneck, the frame rates would remain relatively stable across resolutions, as the CPU workload does not scale with resolution. The data shows a steep decline in FPS with each resolution increase, which is the definitive signature of a GPU-bound scenario. At 4K, the average FPS across all settings ranges from 19 to 35, which is unplayable for a stealth game requiring precise timing. The 1080p to 4K scaling demonstrates that this combo is only viable for 1080p gaming, and even then, only at the lowest settings presets.

How This Combo Ranks

The combo rank for this configuration in Thief is 2534 out of 2851 tested combos, placing it in the bottom 11.1% of all system pairings. This rank is a direct consequence of the Intel Arc B390's performance class. The GPU's 3DMark Steel Nomad score of 1482 places it in the 9th percentile of all GPUs, and its nearest rivals are all low-end parts. The Ryzen 9 9950X3D is a top-tier CPU, ranking in the 95th percentile of all CPUs with an average benchmark score of 75,779, but it cannot compensate for the GPU's limitations.

The CPU's nearest rivals in the benchmark database include the AMD Ryzen 7 PRO 9755 (scoring 75,738, a 0.1% delta), the AMD Ryzen 7 PRO 9755X3D (scoring 75,716, a 0.1% delta), and the AMD EPYC 8224P (scoring 75,582, a 0.3% delta). These rivals are all within 0.3% of the 9950X3D's average score, showing that the CPU is competitive with other high-end parts. However, this CPU performance is wasted in this gaming scenario. The data shows that the combo rank is determined almost entirely by the GPU, as the CPU has ample headroom to handle Thief's workload, which is a 2014 title with modest CPU requirements.

The rank of 2534 out of 2851 means that 317 other tested combos performed worse. This is a stark indicator of how poorly the Arc B390 performs in this game. Even the CPU's high percentile ranking (95th) cannot lift the combo out of the bottom tier. The data suggests that pairing a high-end CPU with this specific integrated GPU is a highly unbalanced configuration for gaming, and the combo rank reflects the real-world consequence of that imbalance. Users with this hardware should expect performance consistent with the bottom 11% of all tested systems.

FAQ

1920x1080 (1080p):

• Low: 86 FPS average
• Medium: 66 FPS average, with a minimum of 56 FPS and a maximum of 75 FPS
• High: 50 FPS average
• Ultra: 48 FPS average

2560x1440 (1440p):

• Low: 59 FPS average
• Medium: 45 FPS average, with a minimum of 38 FPS and a maximum of 52 FPS
