Downfall

The AMD Ryzen 5 7500X3D paired with the Intel Arc B390 delivers a specific and limited performance profile in Downfall, a horror title from 2016. The data shows a system that is heavily constrained by its graphics component, with playable frame rates achievable only at lower resolutions and settings. This analysis examines the measured results to provide practical settings guidance and component-level insights.

Settings Recommendations

The benchmark data for this combo in Downfall reveals a clear hierarchy of performance across four presets, with the most balanced experience found at Medium settings. At 1920x1080, the Medium preset delivers an average of 87 FPS, with a minimum of 74 FPS and a maximum of 100 FPS. This is the only preset at any resolution that provides both a high average frame rate and a minimum frame rate comfortably above the 60 FPS threshold, making it the recommended choice for a smooth experience.

While the Low preset at 1920x1080 achieves a higher average of 106 FPS, the visual fidelity sacrifice is significant for a horror game where atmosphere and detail contribute to the experience. The High preset at 1080p drops to 71 FPS average, which is still playable but leaves less headroom for demanding scenes. The Ultra preset at 1080p falls to 44 FPS average, which is below the ideal smoothness threshold for a genre that benefits from consistent motion.

At 2560x1440, the Medium preset yields 62 FPS average with a minimum of 53 FPS, which is borderline for a smooth experience. The Low preset at 1440p provides 76 FPS average, making it a viable choice for users prioritizing frame rate over visual quality. The High preset at 1440p drops to 51 FPS average, and the Ultra preset at this resolution is not recommended at 32 FPS average.

The 3840x2160 results are largely unusable for smooth gameplay. Even the Low preset at 4K only reaches 47 FPS average, with the Medium preset at 39 FPS and a minimum of 33 FPS. The High preset at 4K yields 32 FPS, and the Ultra preset is a slideshow at 20 FPS. For the best measured experience, the data clearly points to 1920x1080 with the Medium preset, as it is the only configuration that delivers a minimum frame rate above 60 FPS.

GPU Role

The Intel Arc B390 is the primary bottleneck in this configuration. Its benchmark results show a 3DMark Steel Nomad DX12 score of 1482, placing it in the 9th percentile of all GPUs. This is an extremely low ranking, and the nearest rivals confirm its position: the NVIDIA GeForce GT 520MX scores 1463 (1.3% behind), the GeForce 800M scores 1460 (1.5% behind), and the GeForce GT 625 OEM scores 1446 (2.5% behind). The Arc B390 is only 2.7% ahead of the NVIDIA GeForce GT 710, which scores 1443.

The GPU's memory configuration is "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM. The memory bandwidth is listed as "System Dependent," which introduces variability based on the rest of the system. The clock speeds show a base of 300 MHz and a boost of 2500 MHz, but these numbers do not compensate for the fundamental lack of dedicated graphics memory.

The GPU operates with 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. The FP32 performance is 7.680 TFLOPS, and the pixel rate is 60.00 GPixel/s. While these specifications are not the focus of the measured FPS data, they provide context for why the GPU struggles. The texture rate of 120.0 GTexel/s and the FP16 performance of 15.36 TFLOPS (2:1) indicate a chip that is not designed for high-end gaming workloads.

In the context of Downfall, the GPU's limitations are evident in the frame rate scaling. The game is not heavily demanding by modern standards, yet the Arc B390 cannot maintain high frame rates even at 1080p on higher presets. The integrated nature of the GPU, as an IGP with no dedicated power connectors and a TDP of 80 W, further limits its sustained performance.

Resolution Scaling

The measured frame rates show a consistent and predictable drop as resolution increases from 1920x1080 to 3840x2160. At the Medium preset, the average FPS goes from 87 at 1080p to 62 at 1440p, and then to 39 at 4K. This represents a 55% drop from 1080p to 4K, which is a significant loss in performance.

At the Low preset, the scaling is similar: 106 FPS at 1080p, 76 FPS at 1440p, and 47 FPS at 4K. This is a 56% drop from 1080p to 4K. The High preset shows 71 FPS at 1080p, 51 FPS at 1440p, and 32 FPS at 4K, a 55% reduction. The Ultra preset drops from 44 FPS at 1080p to 32 FPS at 1440p and then to 20 FPS at 4K, a 55% decline.

The consistency of these percentage drops across all presets indicates that the resolution scaling is governed by the GPU's fill rate and pixel throughput rather than by CPU limitations. The 24 ROPs of the Arc B390 are a limiting factor, as higher resolutions demand more pixel processing. The data suggests that the GPU is the dominant constraint at all resolutions, and the CPU is not a factor in these frame rate reductions.

The 1080p to 1440p transition is particularly telling. At Medium settings, the drop from 87 to 62 FPS is a 29% reduction, while the 1440p to 4K transition drops from 62 to 39 FPS, a 37% reduction. This shows that the GPU's workload scales superlinearly with resolution, which is expected given the increased pixel count. The fact that the 4K results are all below 50 FPS, even at Low settings, confirms that this GPU is not suited for 4K gaming in Downfall.

How This Combo Ranks

This specific combination of the AMD Ryzen 5 7500X3D and Intel Arc B390 ranks 2589 out of 2928 tested combos in Downfall. This places it in the bottom 12% of all configurations, which aligns with the low GPU percentile ranking. The combo rank reflects the overall gaming performance of the pair, and the data shows that the GPU's weakness drags down the entire system.

The CPU in this combo is a strong performer. The AMD Ryzen 5 7500X3D has an average benchmark score of 44573, placing it in the 89th percentile of all CPUs. Its nearest rivals include the Intel Core Ultra X9 388H (avg score 44466, 0.2% behind), the Intel Core i9-13950HX (avg score 44342, 0.5% behind), and the AMD Ryzen AI Max 385 (avg score 44309, 0.6% behind). The CPU is also 0.7% ahead of the Intel Core i5-14600, which scores 44889.

Despite the CPU's strength, the combo rank of 2589 out of 2928 shows that the GPU is the determining factor for gaming performance. The CPU is capable of handling modern workloads, but in Downfall, the frame rates are limited by the GPU at every resolution and setting. The data indicates that pairing this CPU with a more capable GPU would dramatically improve the combo's ranking, but as measured, the Arc B390 holds the system back.

The gap between the CPU's high percentile (89th) and the GPU's low percentile (9th) is stark. This mismatch is reflected in the combo rank, which sits near the bottom of the distribution. For a user considering this configuration, the data suggests that the CPU is not the limiting factor, and any upgrade to the GPU would yield substantial improvements in Downfall.

CPU Role

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor from the 7000 series, based on the Raphael codename and Zen 4 architecture. It operates at a base clock of 4.00 GHz and a boost clock of 4.50 GHz, with a TDP of 65 W. The CPU has a 96 MB shared L3 cache, which is a defining feature of the X3D series, and it supports DDR5 memory with a dual-channel bus and 83.2 GB/s bandwidth.

In this system, the CPU's role in Downfall is secondary to the GPU. The measured frame rates do not show CPU-related bottlenecks, as the performance scales consistently with resolution and settings. The CPU's benchmark scores demonstrate its capability: a Passmark single-thread score of 3494, a multithread score of 25047, and a physics score of 2779. These numbers place the CPU in the 89th percentile of all CPUs.

The CPU's strong single-thread performance is relevant for a game like Downfall, which likely has a single-threaded game logic component. However, the data does not show any CPU limitation at any resolution. The 1080p Low preset at 106 FPS is the highest measured average, and this is likely near the practical limit of the GPU rather than the CPU. If the CPU were the bottleneck, we would expect to see frame rates plateau at higher resolutions, but the data shows a steady decline with resolution.

The CPU's 12 threads and 96 MB L3 cache provide ample headroom for gaming and multitasking. The data shows that the CPU is not the constraint in this pairing, and the 2589 combo rank is almost entirely attributable to the GPU. For a user with this CPU, the recommendation would be to invest in a more powerful GPU to unlock the CPU's full potential in gaming.
