Downfall

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

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor from the 5000 series, built on the Zen 3 architecture (codenamed Vermeer) at TSMC's 7 nm process. It features a base clock of 3.00 GHz and a boost clock of 4.10 GHz, with a 105 W TDP. The chip carries 64 KB of L1 cache per core, 512 KB of L2 per core, and a substantial 96 MB of shared L3 cache. This large L3 pool is the defining characteristic of the X3D line, and it matters for a game like Downfall, a horror title from 2016 that tends to stress memory latency and cache sensitivity in certain scenes.

Benchmark data shows the processor's multithreaded capabilities are strong relative to its single-thread showing. In Cinebench R23, the multicore score reaches 22366, while the single-core score is 3157. The gap between these numbers indicates that the CPU can leverage all 16 threads effectively, which is useful for background tasks and any engine-level threading in Downfall, but the game itself is not heavily threaded by modern standards. The 3DMark scores reinforce this: the 16-thread score is 6764, the 8-thread score is 5357, and the 4-thread score is 3097. The scaling from 4 to 8 threads is 73%, and from 8 to 16 threads it is 26%, showing diminishing returns as more threads are added. For a 2016 horror title, the engine likely uses 4 to 8 threads at most, so the 5700X3D's 8-core design is more than sufficient.

The CPU's percentile rank against all processors is 77, meaning it outperforms 77% of the CPUs in the benchmark database. Its average benchmark score is 24709. The nearest rival, the AMD Ryzen 5 7600X3D, scores 24728, a delta of -0.1%, meaning the 5700X3D is essentially tied with that chip. The AMD Ryzen 9 5900HX scores 24822 (delta -0.5%), while the Intel Core i5-12450HX scores 24576 (delta +0.5%) and the Intel Core i5-11600 scores 24563 (delta +0.6%). These delta values are all within 1%, indicating that the 5700X3D sits in a tightly packed performance band. None of these rivals have a meaningful edge in raw CPU throughput.

In Downfall, the measured FPS data shows that at 1080p with Low settings, the combo reaches 96 FPS, while at 4K with Ultra, it drops to 18 FPS. The CPU's role becomes more apparent at lower resolutions and settings where the GPU is less of a bottleneck. At 1080p Low, the 96 FPS result suggests the CPU is capable of feeding the GPU adequately at high frame rates. The single-thread score of 804 in 3DMark single-thread is modest, but for a 2016 game, this is not a limiting factor. The 5700X3D's cache configuration likely helps with Downfall's asset streaming and AI routines, which can be cache-sensitive in horror titles with dense environments.

The CPU's memory support is DDR4 with dual-channel configuration, offering 51.2 GB/s of bandwidth. This is adequate for the game's era. The ECC memory support is a feature that does not directly affect gaming performance. The processor has no integrated graphics, so the Intel Arc B370 handles all rendering duties. The launch MSRP is $249, which positions it as a mid-range desktop part, though pricing details are not part of this analysis.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture, codenamed Panther Lake, fabricated on Intel's 3 nm process. It has a base clock of 300 MHz and a boost clock of 2400 MHz. The memory configuration is "System Shared" for size, type, and bus width, with bandwidth described as "System Dependent." This means the GPU does not have dedicated VRAM; it relies on the system memory, which is DDR4 in this case. The shading units number 1280, with 40 texture mapping units and 20 render output units. There are 10 ray tracing cores. The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s. The FP32 performance is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS (2:1 ratio).

The GPU's TDP is just 25 W, and it is classified as an IGP (integrated graphics processor) with no power connectors and a slot width of "IGP." The bus interface is also IGP, meaning it is not a discrete card. Display outputs are "Portable Device Dependent," which suggests this is intended for mobile or compact systems. The API support includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The GPU's benchmark data is sparse: only one test, 3DMark Steel Nomad DX12, with a score of 1184. Its percentile rank against all GPUs is 5, meaning it outperforms just 5% of the GPUs in the database. The average benchmark score is 1184. The nearest rivals are all older, low-end parts: the ATI Mobility Radeon HD 5570 scores 1186 (delta -0.2%), the ATI Radeon HD 5770 scores 1190 (delta -0.5%), the AMD Radeon HD 7650M scores 1192 (delta -0.7%), and the AMD FirePro M2000 scores 1168 (delta +1.4%). This places the Arc B370 in the lowest performance tier of the GPU database. It is not designed for high-end gaming; it is an integrated solution that competes with decade-old discrete mobile GPUs.

In Downfall, the measured FPS data reflects this GPU's limitations. At 1080p Low, the combo achieves 96 FPS, which is playable. However, as resolution and settings increase, the frame rate drops sharply. At 1080p Medium, it falls to 78 FPS; at 1080p High, 64 FPS; and at 1080p Ultra, just 40 FPS. At 1440p, the numbers are 68 FPS (Low), 56 FPS (Medium), 46 FPS (High), and 29 FPS (Ultra). At 4K, the results are 43 FPS (Low), 35 FPS (Medium), 29 FPS (High), and 18 FPS (Ultra). The GPU's lack of dedicated VRAM and low compute throughput become evident at higher resolutions, where the system memory bandwidth bottleneck and the limited pixel fill rate (48.00 GPixel/s) constrain performance.

The 25 W TDP is extremely low, indicating this is not a performance-oriented part. The boost clock of 2400 MHz is high for an integrated GPU, but the small number of shading units (1280) and ROPs (20) limit its actual throughput. The 6.144 TFLOPS FP32 figure is theoretical; real-world gaming performance, as shown by the measured FPS, is far below what that number might suggest. The GPU's role in Downfall is clearly the limiting factor at higher resolution and settings, as the CPU is more than capable of handling the game's logic.

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

The measured FPS data provides four presets—Low, Medium, High, and Ultra—across three resolutions. The goal is to find the preset that offers the best playable experience, balancing frame rate and visual quality.

At 1080p, the Low preset delivers 96 FPS, Medium delivers 78 FPS, High delivers 64 FPS, and Ultra delivers 40 FPS. All of these are above the 30 FPS threshold, but Low is clearly the smoothest. However, Medium at 78 FPS with a minimum of 67 FPS and maximum of 90 FPS provides a more stable experience than Low, which has no min/max data but likely fluctuates more. The Medium preset at 1080p is the best choice because it maintains a high average frame rate while offering better visuals than Low. High at 64 FPS is also acceptable, but the jump from Medium to High costs 14 FPS, which is significant for a horror game where smoothness matters for immersion.

At 1440p, the Low preset drops to 68 FPS, Medium to 56 FPS, High to 46 FPS, and Ultra to 29 FPS. The Medium preset at 1440p delivers 56 FPS with a minimum of 48 FPS, which is still playable, but the drop from 1080p Medium (78 FPS) to 1440p Medium (56 FPS) is 22 FPS, a 28% reduction. High at 46 FPS is borderline, and Ultra at 29 FPS is below the 30 FPS playability threshold. For 1440p, the Medium preset is the recommended choice, as it stays above 30 FPS and offers a reasonable visual upgrade over Low.

At 4K, the situation is dire. Low delivers 43 FPS, Medium 35 FPS (with a minimum of 30 FPS and maximum of 40 FPS), High 29 FPS, and Ultra 18 FPS. The Medium preset at 4K is the only one that maintains an average above 30 FPS, but its minimum of 30 FPS means it will occasionally dip below that. Low at 43 FPS is playable but visually sparse. For 4K, the Low preset is the safest recommendation, as it provides the highest average frame rate. However, if visual quality is a priority and the user can tolerate occasional dips, Medium at 35 FPS is acceptable.

Across all resolutions, the pattern is clear: the GPU is the bottleneck, and the Medium preset offers the best balance of frame rate and visual fidelity. At 1080p, Medium is the sweet spot. At 1440p, Medium is still viable. At 4K, Low is the only reliable option for consistent playability. The Ultra preset is not recommended at any resolution, as it drops below 30 FPS at 1440p and 4K, and even at 1080p it only reaches 40 FPS, which is suboptimal for a horror game that benefits from responsive controls.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo of the AMD Ryzen 7 5700X3D and the Intel Arc B370 ranks 2688 out of 2928 tested combos in Downfall. This places it in the bottom 8% of all combinations tested, with a percentile position that is clearly in the lower tier. The rank of 2688 out of 2928 means that only 240 combos perform worse, and the vast majority of tested systems achieve higher frame rates.

This low rank is almost entirely attributable to the GPU. The CPU's percentile rank of 77 is respectable, but the GPU's percentile rank of 5 drags the overall combo down. The measured FPS data confirms this: at 1080p Ultra, the combo only manages 40 FPS, which is far below what a mid-range discrete GPU would achieve. The GPU's nearest rivals are all integrated or low-end discrete parts from over a decade ago, and the Arc B370's score of 1184 in 3DMark Steel Nomad DX12 is the only benchmark available for it.

The combo's rank in Downfall is not a reflection of the CPU's capabilities. The 5700X3D is a strong processor, as evidenced by its Cinebench R23 multicore score of 22366 and its 77th percentile rank. However, the GPU's performance is so limited that it caps the entire system. In a game like Downfall, which is not particularly demanding by modern standards, this combo struggles at higher settings and resolutions, but it can achieve playable frame rates at 1080p Low to Medium.

When compared to other combos in the database, this pairing is clearly at the lower end. The rank of 2688 out of 2928 suggests that users would need to significantly lower settings or resolution to get a smooth experience. The data shows that at 1080p Low, the combo reaches 96 FPS, which is acceptable, but any increase in graphical fidelity comes at a steep cost. The GPU's 5th percentile rank means that 95% of GPUs in the database are faster, and this is the primary driver of the combo's low overall rank.

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

The measured FPS data across resolutions reveals a clear trend: performance degrades significantly as resolution increases, indicating that the GPU is the limiting component. At Low settings, the average FPS drops from 96 at 1080p to 68 at 1440p, then to 43 at 4K. This is a 29% drop from 1080p to 1440p, and a 37% drop from 1440p to 4K. The total drop from 1080p to 4K is 55%, meaning the frame rate is nearly halved.

At Medium settings, the average FPS goes from 78 at 1080p to 56 at 1440p, then to 35 at 4K. The drop from 1080p to 1440p is 28%, and from 1440p to 4K is 38%. The total drop is 55% again, consistent with the Low preset. At High settings, the average FPS drops from 64 at 1080p to 46 at 1440p, then to 29 at 4K. This is a 28% drop from 1080p to 1440p, and a 37% drop from 1440p to 4K, with a total drop of 55%. At Ultra settings, the average FPS drops from 40 at 1080p to 29 at 1440p, then to 18 at 4K. The drop from 1080p to 1440p is 28%, and from 1440p to 4K is 38%, with a total drop of 55%.

The consistency of these percentage drops across all settings is telling. A 55% reduction in frame rate from 1080p to 4K is characteristic of a GPU-bound system, where the number of pixels being rendered increases by a factor of four (though the exact pixel counts are not in the fact pack). The CPU's performance does not scale with resolution; it processes the same game logic regardless of how many pixels are drawn. Therefore, the fact that FPS drops uniformly with resolution indicates that the GPU is saturated and cannot keep up with the increased pixel workload.

The GPU's system-shared memory and low bandwidth (described as "System Dependent") exacerbate this issue. At 4K, the GPU must access system memory for textures and frame buffers more frequently, and the shared nature of the memory bus creates a bottleneck. The CPU, with its 51.2 GB/s memory bandwidth, is not the issue here; the GPU's lack of dedicated VRAM and its low compute throughput (6.144 TFLOPS FP32) are the limiting factors.

The resolution scaling data also shows that the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the difference between Low (96 FPS) and Ultra (40 FPS) is 56 FPS. At 1440p, the difference is 39 FPS (68 vs 29). At 4K, the difference is 25 FPS (43 vs 18). This narrowing suggests that at higher resolutions, the GPU is so overwhelmed that the settings have less impact on performance; the pixel fill rate becomes the dominant constraint. The pixel rate of 48.00 GPixel/s is simply too low for 4K gaming, regardless of settings.
