Downfall

The AMD Ryzen 5 4600G paired with the Intel Arc B390 produces a playable but constrained experience in Downfall, with performance scaling that clearly identifies the integrated GPU as the primary bottleneck. The combination ranks near the bottom of the database, at 2589 out of 2928 tested combos, placing it in the 12th percentile of all systems. Across all resolutions, the average frame rates range from a low of 20 FPS at 4K Ultra to a high of 106 FPS at 1080p Low, indicating that while the CPU has sufficient headroom, the graphics solution limits the overall experience.

Resolution Scaling

The measured frame rates show a steep decline as resolution increases, a pattern that points directly at the GPU as the limiting factor. At 1080p High, the system delivers 71 FPS, but this drops to 51 FPS at 1440p High and further to 32 FPS at 4K High. This represents a 55% reduction in performance from 1080p to 4K at the High preset, which is a classic symptom of a graphics-bound workload where the rendering pipeline cannot keep up with the increasing pixel count.

The scaling pattern becomes even more telling when examining the Low settings across resolutions. At 1080p Low, the system achieves 106 FPS, which drops to 76 FPS at 1440p Low and 47 FPS at 4K Low. The percentage drop from 1080p to 1440p is 28%, while the drop from 1440p to 4K is 38%. This accelerating degradation with resolution suggests that the GPU’s shading units and memory bandwidth are saturated, as the Arc B390 relies on system shared memory with bandwidth described as "System Dependent."

The Medium preset, which includes minimum and maximum frame rate data, provides additional insight. At 1080p Medium, the average is 87 FPS with a range of 74 to 100 FPS. At 1440p Medium, this falls to 62 FPS with a range of 53 to 71 FPS. At 4K Medium, the average drops to 39 FPS with a range of 33 to 44 FPS. The consistency of the frame pacing, as evidenced by the tight min-max ranges, indicates that the performance ceiling is stable rather than erratic, which is typical of a GPU that is consistently maxed out.

The Ultra preset shows the most dramatic resolution sensitivity. At 1080p Ultra, the system manages 44 FPS, which is already marginal for a horror game. At 1440p Ultra, this drops to 32 FPS, and at 4K Ultra, it collapses to 20 FPS. The 55% reduction from 1080p Ultra to 4K Ultra mirrors the High preset drop, confirming that the GPU’s compute resources are the limiting factor rather than any CPU-side constraint. The data suggests that resolution scaling in Downfall is almost entirely GPU-bound for this combo, with the CPU showing no signs of becoming a bottleneck even at the lowest resolution and settings.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its benchmark scores show a substantial multi-threaded capability, with a Cinebench R23 multicore score of 13593 and a Geekbench multicore score of 6637. The single-thread performance is more modest, with a Cinebench R23 single-core score of 1919 and a Geekbench single-core score of 1460, but this is adequate for gaming workloads that typically rely on a mix of single and multi-threaded tasks.

In the context of Downfall, the CPU’s role appears to be secondary to the GPU. The fact that the frame rate drops consistently from 106 FPS at 1080p Low to 47 FPS at 4K Low, with no sign of a CPU-induced plateau, indicates that the processor is not the limiting component in any configuration tested. The 3DMark scores support this interpretation: the 2-thread score of 1430 and the 4-thread score of 2732 suggest that even older games with lower thread utilization would not be constrained by this CPU in most scenarios.

The CPU’s 8 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for feeding the GPU, but the system shared memory architecture of the Arc B390 means that the CPU’s memory controller also handles graphics data. This could theoretically create a shared bandwidth bottleneck, but the measured results do not show this as a primary issue, since the frame rates scale smoothly with resolution rather than exhibiting sudden drops that would indicate memory contention.

The Ryzen 5 4600G’s percentile ranking of 71 among all CPUs suggests it is a mid-range processor, and its nearest rivals include the AMD Ryzen 3 PRO 5355GE (0.1% faster), the Intel Core 7 150U (0.6% slower), and the Intel Core i3-14100T (0.8% faster). These close margins indicate that the CPU is performing as expected for its class, and the game’s performance is not being artificially held back by a weak processor. The data shows that the CPU is providing a stable platform for the GPU to work within its limits.

GPU Role

The Intel Arc B390 is the clear limiting factor in this combination. This integrated GPU, based on the Xe3-LPG architecture on a 3 nm process, features 1536 shading units, 48 texture mapping units, and 24 raster output units. Its 12 ray tracing cores and support for DirectX 12 Ultimate indicate modern feature support, but its raw throughput is limited. The FP32 performance is rated at 7.680 TFLOPS, and the pixel rate is 60.00 GPixel/s with a texture rate of 120.0 GTexel/s.

The GPU’s benchmark results are stark. In 3DMark Steel Nomad DX12, it scores 1482, which places it in the 9th percentile of all GPUs. Its nearest rivals are older, low-end discrete GPUs: the NVIDIA GeForce GT 520MX (1.3% faster), the NVIDIA GeForce 800M (1.5% faster), the NVIDIA GeForce GT 625 OEM (2.5% faster), and the NVIDIA GeForce GT 710 (2.7% faster). This positioning makes it clear that the Arc B390 is not a gaming-focused part, and its performance in Downfall reflects this.

The GPU’s clock speeds are notable: a base clock of 300 MHz and a boost clock of 2500 MHz. This wide range suggests that the GPU can ramp up significantly under load, but the thermal and power constraints of an integrated design (80 W TDP) likely prevent sustained high clocks. The memory situation is particularly important for a game like Downfall, as the GPU uses "System Shared" memory with "System Dependent" bandwidth. This means the GPU is competing with the CPU for memory access, which can reduce effective bandwidth in demanding scenes.

The measured frame rates align with the GPU’s low benchmark scores. At 1080p Low, the 106 FPS average shows that the GPU can handle light loads, but the steep drop to 44 FPS at 1080p Ultra indicates that the shading units are quickly overwhelmed by higher graphical fidelity. The 4K results, ranging from 20 FPS at Ultra to 47 FPS at Low, confirm that the GPU lacks the fill rate and memory bandwidth for high-resolution rendering. The data indicates that the Arc B390 is the primary determinant of performance in this combo, and its capabilities are the ceiling for the entire system.

How This Combo Ranks

The AMD Ryzen 5 4600G and Intel Arc B390 combination ranks 2589 out of 2928 tested combos in Downfall, placing it in the bottom 12% of all systems. This rank is consistent with the individual component performance: the CPU sits at the 71st percentile among all processors, while the GPU sits at the 9th percentile among all GPUs. The low GPU ranking dominates the overall combo performance, as the game is heavily graphics-bound.

The rank position indicates that this combo is significantly below average for gaming, but it is not the worst tested. The 339 combos ranked below this one likely feature even older or weaker integrated graphics or severely mismatched CPU-GPU pairings. In the context of this database, the combo’s performance is predictable given the GPU’s benchmark scores, and the system behaves as expected for a modern integrated graphics solution.

The CPU’s performance relative to its rivals shows that the processor is not the issue. The Ryzen 5 4600G’s average benchmark score of 17507 is nearly identical to its nearest rivals, with deltas of only 0.1% to 0.8%. This means that swapping the CPU for a marginally faster model would not meaningfully improve Downfall performance, as the GPU would remain the bottleneck. Conversely, the GPU’s rivals are all older NVIDIA parts that are only slightly slower, confirming that the Arc B390 is at the very bottom of the graphics performance spectrum.

The data indicates that this combo is best suited for low-resolution, low-settings gaming or non-gaming workloads. Its rank of 2589 suggests that users should not expect a smooth experience at high resolutions or settings in Downfall, and the system is more appropriate for older titles or indie games with lower graphical demands.

Settings Recommendations

Based on the measured frame rates, the optimal settings for this combo depend on the target resolution and the user’s preference for smoothness versus visual fidelity. At 1080p, the Medium preset is the recommended choice, delivering an average of 87 FPS with a minimum of 74 FPS and a maximum of 100 FPS. This provides a consistently smooth experience that is well above the 60 FPS threshold, with only minor visual compromises compared to High settings.

For users who prioritize visual quality over frame rate, the High preset at 1080p offers 71 FPS, which is still playable and provides better graphical detail. The Ultra preset at 1080p drops to 44 FPS, which may be acceptable for a horror game where atmosphere matters more than fast action, but it carries the risk of frame drops in demanding scenes. The Low preset at 1080p achieves 106 FPS, but the visual quality reduction is likely too severe for most players.

At 1440p, the Medium preset is the most viable option, with an average of 62 FPS and a minimum of 53 FPS. This is playable, though it may dip below 60 FPS in intense moments. The High preset at 1440p averages 51 FPS, which is borderline, while the Low preset at 76 FPS is smooth but visually basic. The Ultra preset at 1440p, with an average of 32 FPS, is not recommended for general play.

At 4K, the options are limited. The Low preset averages 47 FPS, which is the only setting that approaches playability, but it comes with significant visual compromises. The Medium preset averages 39 FPS, and the High preset drops to 32 FPS. The Ultra preset at 4K, with an average of 20 FPS, is effectively unplayable. For 4K gaming, users should stick to Low settings and accept the visual quality reduction, or consider lowering the resolution to 1440p for a better experience.

The data supports a clear recommendation: the Medium preset at 1080p offers the best overall experience for this combo, balancing visual quality and performance. For users with a 1440p monitor, Medium is also the best choice, while 4K gaming should be avoided unless the user is willing to accept Low settings and frame rates below 50 FPS. The measured frame times at Medium settings show good consistency, with the 1080p range of 74 to 100 FPS indicating minimal stuttering, which is important for maintaining immersion in a horror game.
