Downfall

The AMD Ryzen 7 5700G and Intel Arc B390 combination delivers playable frame rates in Downfall only at lower resolutions and settings, with the system ranking in the bottom 12% of all tested configurations. The data indicates a severe GPU bottleneck, as the Arc B390's integrated-class performance consistently limits the 8-core CPU's potential.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5700G is a desktop processor built on the Zen 3 architecture (Cezanne codename) using TSMC's 7 nm process. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. The CPU's 16 MB of L3 cache and dual-channel DDR4 memory support (51.2 GB/s bandwidth) provide adequate bandwidth for gaming workloads. Its 65 W TDP and unlocked multiplier make it a flexible platform component, while the integrated Radeon Vega 8 graphics serve as a fallback, though the system under analysis uses the discrete-class Intel Arc B390.

In synthetic benchmarks, the Ryzen 7 5700G scores 12,830.5 in Cinebench R23 multi-core and 1,494 in single-core. The 3DMark results show scaling from 899 (single-thread) to 6,629 (16-thread), indicating solid multi-threading efficiency. Relative to other CPUs, it sits at the 79th percentile, with an average benchmark score of 27,051. Its nearest rivals include the Intel Core i9-9900K (27,097, -0.2% delta), AMD Ryzen AI 7 445 (26,936, +0.4%), Intel Core i5-14400T (27,166, -0.4%), and Intel Core i7-1370P (26,900, +0.6%). These margins are negligible, showing the 5700G is competitive with mid-range and older high-end processors.

However, in Downfall, the CPU's theoretical strength is largely irrelevant. The measured frame rates show that even at 1080p Low, the system achieves 106 FPS, which is the highest score recorded. At 1080p High, it drops to 71 FPS. This pattern — where lowering settings yields substantial gains — points to the GPU as the limiting factor. The Intel Arc B390, with its 1,536 shading units, 48 TMUs, and 24 ROPs, delivers only 7.680 TFLOPS of FP32 performance. Its 3DMark Steel Nomad DX12 score of 1,482 places it at the 9th percentile among all GPUs, with nearest rivals being the NVIDIA GeForce GT 520MX (1,463, +1.3%), GeForce 800M (1,460, +1.5%), GT 625 OEM (1,446, +2.5%), and GT 710 (1,443, +2.7%). This GPU is fundamentally entry-level, and the CPU cannot compensate for its limitations.

The 5700G's 16 threads do help maintain minimum frame rates in CPU-light scenes, but the bottleneck manifests clearly in the resolution scaling. As resolution increases from 1080p to 4K, the frame rate drops proportionally more than the pixel count increases, confirming that the Arc B390's fill rate and shading capacity are exhausted. The CPU's role here is to feed the GPU adequately; it does so without becoming the primary constraint, as evidenced by the fact that average FPS scales almost linearly with GPU load.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

*Q: What is the best performance this combo can achieve in Downfall?*

A: The highest measured average FPS is 106 at 1920x1080 with Low settings. This is the only configuration that breaks the 100 FPS threshold, and it represents the ceiling for this combination.

Q: How does the Intel Arc B390 compare to its closest GPU rivals?

A: The Arc B390 scores 1,482 in 3DMark Steel Nomad DX12, which is 1.3% higher than the NVIDIA GeForce GT 520MX (1,463), 1.5% higher than the GeForce 800M (1,460), 2.5% higher than the GT 625 OEM (1,446), and 2.7% higher than the GT 710 (1,443). These are all sub-10th percentile GPUs, indicating the Arc B390 is at the very bottom of the performance spectrum.

Q: Is the Ryzen 7 5700G a bottleneck at 4K resolution?

A: No. At 3840x2160 Ultra, the system averages 20 FPS, while at 1440p Ultra it averages 32 FPS, and at 1080p Ultra it averages 44 FPS. The consistent ~12 FPS gap between each resolution step at Ultra settings shows the GPU is the limiting factor, not the CPU, which maintains identical multi-threaded performance regardless of resolution.

Q: What settings provide the most stable frame pacing at 1440p?

A: The Medium preset at 2560x1440 yields 62 FPS average with a minimum of 53 FPS and maximum of 71 FPS. This is the only 1440p configuration with reported min/max values, and the 9 FPS spread between min and max indicates relatively consistent frame pacing compared to other settings.

Q: How does this CPU compare to the Intel Core i9-9900K?

A: The Ryzen 7 5700G has an average benchmark score of 27,051, which is 0.2% lower than the i9-9900K's 27,097. This puts them statistically at parity, with the 5700G offering similar multi-threaded performance despite being a generation newer.

Q: Does the system achieve playable frame rates at 4K?

A: At 3840x2160, the highest average FPS is 47 with Low settings, and 32 FPS with High settings. Only the Low preset at 4K exceeds 30 FPS, and even then it falls short of 60 FPS. Medium and Ultra presets at 4K average 39 FPS and 20 FPS respectively, making 4K gaming impractical except at the lowest settings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured data reveals a clear pattern of GPU-bound scaling across all settings. At Low settings, the average FPS progresses from 106 at 1080p, to 76 at 1440p, to 47 at 4K. This represents a 28.3% drop from 1080p to 1440p, and a 38.2% further drop from 1440p to 4K. For comparison, the pixel count increases by 77.8% from 1080p to 1440p and by 125% from 1440p to 4K. The FPS drops are proportionally smaller than the pixel increases, which is typical for a GPU that is already near its limits at lower resolutions — the additional workload doesn't scale linearly because the GPU is already saturated.

At Medium settings, the pattern is similar: 87 FPS at 1080p, 62 FPS at 1440p, and 39 FPS at 4K. The drop from 1080p to 1440p is 28.7%, nearly identical to the Low setting's drop, suggesting the GPU's compute resources are consistently the constraint. At High settings, the progression is 71 FPS (1080p), 51 FPS (1440p), and 32 FPS (4K), with a 28.2% drop from 1080p to 1440p. Ultra settings show the steepest absolute decline: 44 FPS at 1080p, 32 FPS at 1440p, and 20 FPS at 4K — a 27.3% drop followed by a 37.5% drop.

The consistency of these percentage drops across all four settings presets is the key indicator. If the CPU were the bottleneck, the FPS would remain relatively flat as resolution increases, because the CPU's workload doesn't change with resolution. Instead, every setting shows roughly a 28% reduction from 1080p to 1440p and a further 35-38% reduction from 1440p to 4K. This aligns with the GPU's fill rate and pixel throughput limitations. The Arc B390's 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are simply insufficient for higher resolutions, and the system's frame rate tracks these hardware limits rather than any CPU constraint.

The min/max FPS data at Medium settings reinforces this: at 1080p, the range is 74-100 FPS (26 FPS spread); at 1440p, it's 53-71 FPS (18 FPS spread); at 4K, it's 33-44 FPS (11 FPS spread). The narrowing spread at higher resolutions indicates the GPU is becoming fully saturated, reducing frame time variance as it works at maximum capacity. This is a classic symptom of GPU bottlenecking, where the GPU's fixed performance ceiling dominates regardless of scene complexity.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers its best results. Low settings average 106 FPS, which is the only triple-digit result in the entire dataset. Medium settings average 87 FPS with a minimum of 74 FPS and maximum of 100 FPS, showing a 26 FPS variance that suggests occasional dips below the average. High settings average 71 FPS, still comfortably above the 60 FPS threshold for smooth gameplay. Ultra settings drop to 44 FPS, which is below the ideal smoothness threshold but still playable for a horror title where atmospheric pacing matters more than twitch reaction.

At 2560x1440, performance degrades noticeably. Low settings average 76 FPS, which remains playable but represents a 28.3% reduction from the 1080p result. Medium settings average 62 FPS with a minimum of 53 and maximum of 71, meaning the system can dip below 60 FPS during demanding scenes. High settings average 51 FPS, which is borderline for smooth gameplay. Ultra settings average 32 FPS, which is below the 30 FPS minimum for acceptable playability in most genres, though horror games can sometimes tolerate lower frame rates.

At 3840x2160, the system struggles. Low settings average 47 FPS, which is the only 4K configuration above 40 FPS. Medium settings average 39 FPS with a minimum of 33 and maximum of 44, putting the minimum right at the edge of playability. High settings average 32 FPS, which barely clears the 30 FPS threshold. Ultra settings average 20 FPS, which is effectively unplayable for any interactive experience. The gap between Low and Ultra at 4K is 27 FPS, compared to a 62 FPS gap at 1080p, showing that the GPU's performance ceiling compresses the settings range as resolution increases.

The Medium settings provide the most complete data with min/max values at all three resolutions. The 1080p Medium result (87 FPS avg, 74 min, 100 max) offers a balanced experience, while the 1440p Medium (62 FPS avg, 53 min, 71 max) is the best high-resolution option. The 4K Medium (39 FPS avg, 33 min, 44 max) shows that even this modest preset cannot maintain 60 FPS at 4K, confirming the GPU's fundamental inadequacy for this resolution.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 7 5700G and Intel Arc B390 ranks 2,589 out of 2,928 tested combos in Downfall. This places it in the bottom 11.6% of all configurations, meaning roughly 88% of tested systems outperform it. The rank of 2,589 is particularly telling given the CPU's relatively strong position — the Ryzen 7 5700G sits at the 79th percentile among all CPUs, but the GPU's 9th percentile ranking drags the entire combo down.

The disparity between CPU and GPU percentiles (79 vs 9) is extreme. A 70-point gap between component percentiles typically indicates a severe imbalance, and in this case, the GPU is unequivocally the weak link. The combo's rank of 2,589 is much closer to the GPU's percentile position than the CPU's, confirming that the Arc B390's performance dictates the overall experience. If the CPU were the limiting factor, the combo rank would likely fall near the 79th percentile (roughly rank 615 out of 2,928), but instead it sits near the bottom.

Compared to other combos, this system would be expected to perform similarly to configurations pairing the Ryzen 7 5700G with other sub-10th percentile GPUs. The GPU's nearest rivals — GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — are all legacy or entry-level parts, and any combo using them would likely rank in a similar range. The 2,589 rank suggests that in a game like Downfall, which has modest system requirements, the GPU's low fill rate and compute capacity prevent the capable CPU from demonstrating any advantage.

For context, the rank of 2,589 means there are 339 combos that perform worse. These would likely pair even weaker GPUs with older or less capable CPUs. However, the fact that this combo outperforms only 11.6% of tested systems underscores that the Arc B390 is not suitable for modern gaming at competitive settings, even in a horror game released in 2016. The combo's rank is a direct consequence of the GPU's 9th percentile standing, and no amount of CPU headroom can compensate for this fundamental hardware limitation.

Settings Recommendations — which preset gives the best experience per the measured rows

The data supports Medium settings at 1920x1080 as the optimal configuration for this combo. This preset delivers 87 FPS average with a minimum of 74 FPS, ensuring that frame rates never drop below 60 FPS even during demanding scenes. The 74 FPS minimum is higher than the average FPS of any 1440p or 4K preset, and the 26 FPS spread between min and max (74-100) indicates acceptable frame pacing for a horror game. Low settings at 1080p offer 106 FPS, but the jump to Medium only costs 19 FPS (17.9% reduction) while providing noticeably better visual quality. High settings at 1080p drop to 71 FPS average, which is still smooth but lacks the safety margin of Medium's 74 FPS minimum.

If the user prioritizes visual fidelity over frame rate, High settings at 2560x1440 (51 FPS average) is the highest-quality preset that remains above 30 FPS. However, the 51 FPS average leaves no headroom for frame drops, and without min/max data, there's risk of dips below 45 FPS during intense scenes. A safer alternative is Medium settings at 2560x1440, which averages 62 FPS with a minimum of 53 FPS. The 53 FPS minimum is acceptable for a horror game, where slower pacing and atmospheric tension are more important than competitive frame rates. This configuration provides a 1440p experience while maintaining playable performance, though it sacrifices the visual detail of High settings.

At 4K, only Low settings (47 FPS average) are viable, and even this is marginal. The 47 FPS average is below 60 FPS and likely dips into the 30s during complex scenes. Medium settings at 4K (39 FPS average, 33 FPS minimum) are technically playable but uncomfortable for extended sessions. Ultra settings at any resolution are not recommended: 44 FPS at 1080p, 32 FPS at 1440p, and 20 FPS at 4K all fall short of smooth gameplay, and the visual improvements over High or Medium are unlikely to compensate for the frame rate penalty.

The best balance of visual quality and performance is Medium at 1080p (87 FPS average, 74 FPS minimum). For users with 1440p displays, Medium at 1440p (62 FPS average, 53 FPS minimum) is the recommended fallback. This combo should avoid Ultra settings entirely, as the 20-44 FPS range across resolutions is insufficient for consistent gameplay. The data shows that Medium settings at 1080p or 1440p provide the most stable experience, with the GPU's limitations making High and Ultra settings impractical beyond 1080p.
