Downfall

FAQ

Q: What is the average FPS for this combo at 1920x1080 with High settings?

A: The recorded average is 71 FPS, with no min or max data captured for that preset. This clears the 60 FPS playable threshold.

Q: Can this system run Downfall at 3840x2160?

A: No. The best recorded average at 4K is 47 FPS on Low settings, which is below the 60 FPS threshold. No settings preset at this resolution reaches playable frame rates.

Q: Which settings preset at 2560x1440 provides the best playable experience?

A: Medium settings at 2560x1440 delivers an average of 62 FPS, with a minimum of 53 and maximum of 71. Low settings also clears 60 FPS at 76 FPS average, but Medium is the most demanding preset that stays playable.

Q: How does the Intel Arc B390 compare to its closest rival in GPU benchmarks?

A: The Arc B390 scores 1482 in the 3DMark Steel Nomad DX12 test. Its nearest rival, the NVIDIA GeForce GT 520MX, scores 1463, which is 1.3% lower. The GeForce 800M is 1.5% behind, the GT 625 OEM is 2.5% behind, and the GT 710 is 2.7% behind.

Q: What is the combo's rank among all tested system combinations for Downfall?

A: This combination ranks 3303 out of 3716 tested combos. That places it in the lower percentile of systems tested, reflecting the GPU's low benchmark standing.

Q: What is the highest playable settings preset at 1920x1080?

A: High settings at 1920x1080 delivers 71 FPS average and is the most demanding preset that stays at or above 60 FPS. Medium runs at 87 FPS average, and Low runs at 106 FPS average, but High is the best playable option.

CPU and GPU Roles

The benchmark data for Downfall shows a clear pattern: the GPU is the primary constraint at every resolution tested. The Intel Arc B390's 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, which is extremely low. Its nearest rivals are all low-end NVIDIA parts from over a decade ago, including the GT 520MX (1.3% higher), GeForce 800M (1.5% higher), GT 625 OEM (2.5% higher), and GT 710 (2.7% higher). This benchmark profile indicates the GPU is fundamentally limited.

Meanwhile, the AMD Ryzen 5 5500 sits in the 73rd percentile of all CPUs, with an average benchmark score of 19593. Its nearest rivals are closely matched: the AMD Ryzen AI 5 430 is 0.1% behind, the Intel Core i5-12500 is 0.4% ahead, the Intel Core i7-10700F is 0.5% behind, and the Intel Core i5-11600KF is 0.7% ahead. The CPU has substantial headroom for gaming workloads.

The resolution scaling data confirms this imbalance. At 1920x1080, the system averages 106 FPS on Low settings. Moving to 2560x1440 Low drops that to 76 FPS, a reduction of 30 FPS or roughly 28%. At 3840x2160 Low, the average falls to 47 FPS, another 29 FPS drop from 1440p. These large frame rate penalties across resolution steps point to pixel throughput limits, which is a GPU-side constraint.

The settings scaling within each resolution tells the same story. At 1080p, going from Low to Medium costs 19 FPS (106 to 87), and from Medium to High costs another 16 FPS (87 to 71). The jump from High to Ultra costs 27 FPS (71 to 44). At 1440p, Low to Medium costs 14 FPS (76 to 62), Medium to High costs 11 FPS (62 to 51), and High to Ultra costs 19 FPS (51 to 32). At 4K, Low to Medium costs 8 FPS (47 to 39), Medium to High costs 7 FPS (39 to 32), and High to Ultra costs 12 FPS (32 to 20).

The pattern shows that raising resolution has a larger impact than raising settings within a resolution. For example, moving from 1080p Low to 1440p Low costs 30 FPS, while moving from 1080p Low to 1080p Ultra costs 62 FPS. The resolution penalty is proportionally severe at every step, indicating the GPU's fill rate and memory bandwidth (listed as "System Shared" and "System Dependent") are the limiting factors. The CPU, with its 6 cores and 12 threads at boost clocks up to 4.20 GHz, is not the bottleneck in any of these configurations.

Best Settings per Resolution

3840x2160: No settings preset achieves 60 FPS. The closest is Low at 47 FPS average. Medium averages 39 FPS, High averages 32 FPS, and Ultra averages 20 FPS. The database records no playable settings at this resolution.

2560x1440: Medium settings is the best playable preset, averaging 62 FPS with a minimum of 53 and maximum of 71. Low settings averages 76 FPS and is also playable, but Medium is more demanding while staying above the 60 FPS threshold. High settings averages 51 FPS, which falls below playable, and Ultra averages 32 FPS.

1920x1080: High settings is the best playable preset, averaging 71 FPS. Medium averages 87 FPS with a minimum of 74 and maximum of 100, and Low averages 106 FPS. All three are above 60 FPS. Ultra averages 44 FPS and is not playable.

How This Combo Ranks

The AMD Ryzen 5 5500 with Intel Arc B390 combination ranks 3303 out of 3716 tested combos for Downfall. This places it in the bottom 11% of all systems in the database. The rank is driven almost entirely by the GPU, which sits at the 9th percentile of all GPUs. The CPU, by contrast, is at the 73rd percentile. This large gap between component percentiles explains why the system struggles even at lower resolutions.

The measured frame rates align with this rank. At 1080p, the system stays playable on three of four presets, but only just barely on High at 71 FPS. At 1440p, only Low and Medium stay playable. At 4K, nothing clears 60 FPS. This performance profile is consistent with a system in the lower decile of the database.

Similar Performance Alternatives

For the CPU, the nearest rivals in the database are all within 0.7% of the Ryzen 5 5500's average benchmark score of 19593. The AMD Ryzen AI 5 430 scores 19617, which is effectively identical. The Intel Core i5-12500 scores 19668, the Intel Core i7-10700F scores 19499, and the Intel Core i5-11600KF scores 19723. Any of these processors would deliver nearly the same CPU-side performance in Downfall.

For the GPU, the nearest rivals are all low-end NVIDIA parts from the early 2010s. The GeForce GT 520MX scores 1463 (1.3% behind the Arc B390), the GeForce 800M scores 1460 (1.5% behind), the GeForce GT 625 OEM scores 1446 (2.5% behind), and the GeForce GT 710 scores 1443 (2.7% behind). These deltas are small, meaning the Arc B390 would behave nearly identically to any of these GPUs in Downfall.

A system pairing any of the four rival CPUs with the Arc B390 would produce frame rates essentially unchanged from this combo. Similarly, swapping the Arc B390 for any of the four rival GPUs while keeping the Ryzen 5 5500 would produce frame rates within a few percent. The system's performance is constrained by the GPU, so CPU swaps within this rival group would have negligible impact on the measured FPS.

The Verdict

The database's verdict is mixed across resolutions. At 3840x2160, no settings preset reaches 60 FPS, so the system is not playable at 4K. The best option is Low at 47 FPS, which may be acceptable for some players but does not meet the playable threshold.

At 2560x1440, the system is playable on Low (76 FPS) and Medium (62 FPS). The best playable preset is Medium, with a 62 FPS average. High settings at 51 FPS and Ultra at 32 FPS fall short.

At 1920x1080, the system is playable on Low (106 FPS), Medium (87 FPS), and High (71 FPS). The best playable preset is High at 71 FPS. Ultra at 44 FPS is not playable.

In summary, this PC can run Downfall at 1080p with High settings and at 1440p with Medium settings, both comfortably above 60 FPS. At 4K, it cannot maintain playable frame rates on any preset.

The only presets with complete min and max data are Medium at each resolution. At 1080p Medium, the frame range spans 74 to 100 FPS, a 26 FPS spread. At 1440p Medium, the range is 53 to 71 FPS, an 18 FPS spread. At 4K Medium, the range is 33 to 44 FPS, an 11 FPS spread. The narrowing range at higher resolutions suggests the GPU is consistently saturated, leaving less variance in frame times. The system's performance ceiling is clearly defined by the Arc B390's rendering throughput, not by the Ryzen 5 5500's processing power.
