Downfall

The AMD Ryzen 5 5500 paired with the Intel Arc B370 presents a peculiar case in Downfall, a 2016 horror title that remains demanding on modern hardware. The benchmark data reveals a combination that is heavily constrained by its graphics component, with the CPU showing significant headroom across all tested settings. This analysis breaks down the measured performance, contextualizes it against rival components, and offers clear recommendations based strictly on the provided data.

Resolution Scaling

The performance trajectory from 1080p to 4K clearly identifies the Intel Arc B370 as the primary bottleneck. At 1920x1080 with Low settings, the combo achieves an average of 96 FPS. Moving to 2560x1440 at Low settings, the average drops to 68 FPS, a reduction of 28 FPS. At 3840x2160 with Low settings, the average plummets to 43 FPS, representing a 53 FPS decline from the 1080p baseline. This steep, linear drop-off is typical of a GPU-limited scenario; the rendering workload at higher resolutions outpaces the Arc B370's capabilities.

The scaling pattern holds across all quality presets. At High settings, the average FPS falls from 64 at 1080p to 46 at 1440p, and then to 29 at 4K. The Ultra preset shows the most dramatic degradation: 40 FPS at 1080p, 29 FPS at 1440p, and a barely playable 18 FPS at 4K. The consistent ~30-40% performance hit for each resolution step up indicates that the GPU's pixel throughput and memory bandwidth (both listed as "System Shared" and "System Dependent") are saturated early, leaving the Ryzen 5 5500's six cores largely idle.

The data suggests that the limiting component is unequivocally the GPU. The Ryzen 5 5500, with a boost clock of 4.20 GHz and a strong multi-threaded benchmark profile, is not the constraining factor. If the CPU were the limit, we would expect performance to remain relatively flat across resolutions, as the CPU workload for a given frame count stays constant. Instead, the FPS drops proportionally with pixel count, a classic signature of GPU-bound operation. The 4K Ultra result of 18 FPS, a 55% drop from 1440p Ultra, reinforces this conclusion, as the Arc B370's 6.144 TFLOPS of FP32 compute is simply overwhelmed by the combined demands of high resolution and maximum settings.

FAQ

*Q: Is the AMD Ryzen 5 5500 + Intel Arc B370 combo capable of running Downfall at 60 FPS?*

A: Yes, but only at 1080p. The measured data shows an average of 64 FPS at 1080p High and 78 FPS at 1080p Medium. At 1440p, the average FPS at High (46) and Medium (56) falls below the 60 FPS threshold, and no 4K preset achieves 60 FPS.

Q: How does the Intel Arc B370 compare to its nearest rivals in raw GPU performance?

Q: Does the Arc B370 have dedicated VRAM?

A: No. The GPU's memory configuration is listed as "System Shared" for size, type, and bus width, with bandwidth listed as "System Dependent." This means it relies on the system's DDR4 memory, which the Ryzen 5 5500 supports in dual-channel mode at 51.2 GB/s.

How This Combo Ranks

In the database of tested combos for Downfall, this pairing of AMD Ryzen 5 5500 and Intel Arc B370 ranks 2688 out of 2928 combos. This places it in the bottom 8% of all tested configurations, a position that aligns with the GPU's weak absolute performance. The combo's rank is a direct reflection of the Arc B370's 5th percentile standing among all GPUs; the CPU's 73rd percentile ranking is not enough to lift the overall result.

The deltaPct values for the CPU's rivals show that the Ryzen 5 5500 is not the source of the low ranking. Its nearest rival, the Intel Core i7-10700F, scores 19499 (deltaPct 0.5%), making the Ryzen 5 5500 slightly faster. The Intel Core i5-12500 scores 19668 (deltaPct -0.4%), and the Intel Core i5-11600KF scores 19723 (deltaPct -0.7%). These negligible differences (all within 1%) confirm that swapping the CPU for a comparable model would have almost no impact on the combo's overall rank in Downfall. The ranking is dominated by the GPU's performance ceiling, which is severely limited by its integrated design and shared memory architecture.

This low rank suggests that users of this combo should have modest expectations. While the CPU is a competent mid-range part, the GPU is positioned at the very bottom of the performance spectrum. The combo's 2688th place finish out of 2928 is a clear signal that this configuration is intended for light or older titles, not demanding modern games at high resolutions. In Downfall, it manages to be playable only at 1080p with reduced settings.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's capabilities in Downfall. At 3840x2160, the results are largely unplayable. Ultra settings yield an average of 18 FPS. High settings improve to 29 FPS, Medium to 35 FPS, and Low to 43 FPS. Even at the lowest settings, the 4K average remains below the 30 FPS playability threshold, with the Medium preset showing a minimum of 30 FPS and a maximum of 40 FPS.

At 2560x1440, the situation improves. Low settings average 68 FPS, which is smooth. Medium settings average 56 FPS, with a minimum of 48 FPS and a maximum of 64 FPS, providing a consistent experience. High settings drop to 46 FPS, and Ultra falls to 29 FPS, making the latter two presets less desirable for sustained gameplay.

At 1920x1080, the combo shows its best performance. Low settings achieve a high average of 96 FPS. Medium settings average 78 FPS, with a minimum of 67 FPS and a maximum of 90 FPS, offering a very good balance. High settings average 64 FPS, which is still playable. Ultra settings average 40 FPS, which is below the ideal smoothness threshold but remains functional for a horror game where slower pacing is common.

The data shows a clear hierarchy: 1080p is the target resolution for this combo, 1440p is playable with reduced settings, and 4K is not recommended for any preset. The min/max FPS data for the Medium presets shows a tight range (e.g., 67-90 at 1080p), indicating stable frame pacing without major stutters, which is a positive sign for the CPU's frame delivery.

GPU Role

The Intel Arc B370 is the decisive component in this combo's performance, and its specifications explain why. The GPU is based on the Xe3-LPG architecture with a Panther Lake chip, built on a 3 nm process. It has 1280 shading units, 40 TMUs, and 20 ROPs. Its clock speeds are listed as a base of 300 MHz and a boost of 2400 MHz. These specs contribute to a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The FP32 compute is rated at 6.144 TFLOPS.

Critically, the memory configuration is "System Shared" across size, type, and bus width, with bandwidth listed as "System Dependent." This is a fundamental limitation. The GPU has no dedicated VRAM of its own and must compete with the CPU for access to the system's DDR4 memory. The Ryzen 5 5500 supports dual-channel DDR4 with a theoretical maximum bandwidth of 51.2 GB/s, but this is shared between the CPU and GPU. In Downfall, a game that requires substantial texture and geometry data, this shared bandwidth becomes a severe bottleneck, especially at higher resolutions.

The GPU's benchmark score of 1184 in 3DMark Steel Nomad (DX12) puts it in the 5th percentile of all GPUs. Its nearest rivals are all older, low-power parts: the ATI Mobility Radeon HD 5570 (1186, -0.2%), ATI Radeon HD 5770 (1190, -0.5%), AMD Radeon HD 7650M (1192, -0.7%), and AMD FirePro M2000 (1168, 1.4%). This places the Arc B370 in the same performance tier as a decade-old discrete GPU, which is consistent with its IGP (Integrated Graphics Processor) designation and 25 W TDP. The data indicates that the GPU's role in this combo is to provide basic 1080p gaming capability, but it lacks the resources (dedicated VRAM, higher bandwidth) to push Downfall to higher resolutions or settings.

CPU Role

The AMD Ryzen 5 5500 plays a supporting, but ultimately non-limiting, role. This is a 6-core, 12-thread processor based on the Zen 3 architecture (Cezanne codename), manufactured on TSMC's 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.20 GHz. Its cache configuration includes 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The CPU's memory support is dual-channel DDR4, with a memory bandwidth of 51.2 GB/s.

In synthetic benchmarks, the Ryzen 5 5500 demonstrates solid multi-threaded performance. It scores 16429 in Cinebench R23 multi-core and 6900 in Cinebench R20 multi-core. Its average benchmark score is 19593, placing it in the 73rd percentile of all CPUs. Its nearest rivals include the AMD Ryzen AI 5 430 (19617, -0.1%), Intel Core i5-12500 (19668, -0.4%), Intel Core i7-10700F (19499, 0.5%), and Intel Core i5-11600KF (19723, -0.7%). These rivals are all within a 1% performance delta, confirming that the Ryzen 5 5500 is a well-positioned mid-range CPU.

In Downfall, the CPU's role is to feed the GPU with frame data. Given the GPU's low performance ceiling, the CPU is rarely stressed. For instance, at 1080p Low, the combo hits 96 FPS, but this is still limited by the GPU's ability to render frames, not the CPU's ability to submit them. The CPU's high single-thread score (2319 in Cinebench R23) ensures that the game's main thread logic is handled efficiently. However, the data shows no instance where the CPU becomes the bottleneck; the FPS drops are entirely correlated with resolution increases, which tax the GPU. The CPU's 73rd percentile ranking is a distant counterpoint to the GPU's 5th percentile, and in this pairing, the CPU's strength is effectively wasted, as it is always waiting for the GPU to finish its work.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. For a smooth, high-refresh experience, 1920x1080 with Low settings is the best choice, yielding an average of 96 FPS. This is the only preset that approaches 100 FPS and is ideal for maximizing frame rate.

For the best balance of visual quality and performance at 1080p, Medium settings are recommended. The average of 78 FPS is well above the 60 FPS threshold, and the minimum of 67 FPS ensures no significant dips. The High preset at 1080p, with an average of 64 FPS, is also viable, but it offers diminishing returns over Medium given the 14 FPS penalty. The Ultra preset at 1080p, averaging 40 FPS, is not recommended for consistent gameplay, as the frame rate can become choppy in intense scenes.

At 2560x1440, the Medium preset is the only sensible option for a playable experience, with an average of 56 FPS and a minimum of 48 FPS. The Low preset averages 68 FPS, which is smoother, but the visual quality reduction from Medium is significant. The High (46 FPS) and Ultra (29 FPS) presets at 1440p are too demanding for this GPU, resulting in frame rates that are below the standard for smooth action.

For 4K resolution, no settings preset is recommended. Even the Low preset averages only 43 FPS, and the Medium preset's minimum of 30 FPS is borderline unplayable. The Ultra preset's 18 FPS average is a slideshow. Users with a 4K display should lower the resolution to 1440p or 1080p for this game.

In summary, the data recommends 1080p Medium as the primary choice for this combo in Downfall, offering a 78 FPS average with a stable frame time range. For users who prioritize frame rate over visuals, 1080p Low at 96 FPS is the alternative. At higher resolutions, users must accept significant compromises, with 1440p Medium being the absolute ceiling for acceptable performance.
