Downfall

The AMD Ryzen 5 7600 paired with the Intel Arc B370 produces a playable but heavily compromised experience in Downfall, with performance collapsing as resolution and settings increase. The data shows this is a GPU-bound system at high resolutions, but the CPU’s strong single-threaded pedigree is insufficient to offset the graphics card’s severe limitations. The Arc B370 ranks in the 5th percentile of all GPUs, and this is reflected in the frame rates, which drop below 30 FPS at 4K Ultra and only reach playable levels at 1080p with low settings.

Resolution Scaling

The measured FPS data reveals a clear and steep performance cliff as resolution increases. At 1080p Low, the system averages 96 FPS, which is the highest score recorded for any configuration. Moving to 1440p Low drops that figure to 68 FPS, a reduction of 28 FPS (or roughly 29%). At 4K Low, the average falls further to 43 FPS, which is a 53 FPS drop from the 1080p baseline—a 55% decrease in performance. This scaling pattern indicates that the Intel Arc B370 is the primary limiting component, as its fillrate and memory bandwidth (both system-shared) are saturated by the increase in pixel count.

The scaling from Medium settings is similarly steep, though less dramatic. At 1080p Medium, the average is 78 FPS, which drops to 56 FPS at 1440p (a 28% reduction) and then to 35 FPS at 4K (a further 38% reduction from 1440p). The 4K Medium result includes a minimum of 30 FPS and a maximum of 40 FPS, showing that even the average is barely above the threshold for playability. The gap between 1440p and 4K is larger than the gap between 1080p and 1440p for every setting, confirming that the GPU’s performance degrades non-linearly as resolution increases.

For High settings, the trend is consistent: 64 FPS at 1080p, 46 FPS at 1440p, and 29 FPS at 4K. The 4K High result is below the 30 FPS playability threshold, and the 1440p High result is borderline. Ultra settings are the worst case, with 40 FPS at 1080p, 29 FPS at 1440p, and only 18 FPS at 4K. The 4K Ultra result is a slideshow, and even 1080p Ultra is not smooth. The data indicates that the resolution scaling is entirely GPU-limited; the Ryzen 5 7600, with its 6 cores and 12 threads, is not the bottleneck here, as evidenced by the consistent frame rate drops that track pixel count rather than CPU workload.

GPU Role

The Intel Arc B370 is an integrated graphics solution on the Panther Lake chip, using the Xe3-LPG architecture on a 3 nm process. Its base clock is 300 MHz, boosting to 2400 MHz, and it has 1280 shading units, 40 TMUs, and 20 ROPs. The memory is system-shared, meaning bandwidth and capacity are dependent on the host system, which is a major constraint in Downfall. The GPU’s 3DMark Steel Nomad DX12 score is 1184, placing it in the 5th percentile of all GPUs, and its nearest rivals include the ATI Mobility Radeon HD 5570 (delta -0.2%) and the AMD Radeon HD 7650M (delta -0.7%). This score reflects a GPU that is several generations behind modern discrete parts, and the game’s frame rates confirm it.

The GPU’s clock behavior is noteworthy: the boost clock of 2400 MHz is high for an integrated part, but the base clock of 300 MHz suggests aggressive power management (TDP is 25 W). In practice, the sustained clock speed under gaming load is likely closer to the boost, but the 20 ROPs and 6.144 TFLOPS FP32 performance are simply insufficient for rendering Downfall at high resolutions. The pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s, but these are theoretical limits that cannot be reached with system-shared memory.

The GPU’s memory being system-shared is the critical weakness. Unlike a dedicated card with its own VRAM, the Arc B370 must compete with the CPU for bandwidth. The Ryzen 5 7600 supports dual-channel DDR5 with a bandwidth of 83.2 GB/s, but this is shared between the CPU and GPU, and the game’s textures and framebuffer will consume a significant portion. This explains why the FPS drops so sharply at 4K, where the memory pressure is highest. The GPU simply cannot feed its shaders fast enough, and the result is the observed 18 FPS at 4K Ultra. The 3DMark score of 1184 is a better predictor of performance than the theoretical TFLOPS, and it aligns with the game’s results: this is a low-end part that struggles with a 2016 horror title.

Settings Recommendations

Based on the measured FPS rows, the optimal experience is at 1080p with Low settings, which delivers 96 FPS. This is the only configuration that achieves a frame rate comfortable for fast-paced action, and it leaves headroom for occasional drops. The 1080p Medium setting is also viable at 78 FPS, with a minimum of 67 FPS and a maximum of 90 FPS, making it the best balance of visual quality and performance if the player accepts slightly lower frame rates. The 1080p High setting at 64 FPS is playable but not ideal, as it may dip below 60 FPS in demanding scenes.

At 1440p, the only recommended setting is Low, which yields 68 FPS. The Medium setting at 56 FPS (min 48, max 64) is borderline, but the minimum of 48 FPS is too low for a consistent experience. The High setting at 46 FPS is not recommended, and Ultra at 29 FPS is unplayable. At 4K, no setting is recommended: Low at 43 FPS is technically above 30 FPS, but it is a poor visual experience, and Medium at 35 FPS (min 30) is too close to the edge. The High and Ultra settings, at 29 and 18 FPS respectively, should be avoided entirely.

The data suggests that players should prioritize resolution over settings. Dropping from 1440p Medium to 1080p Medium provides a 22 FPS gain (from 56 to 78), which is more impactful than dropping from 1440p High to 1440p Medium (a 10 FPS gain). The sweet spot is 1080p Medium, which offers a 78 FPS average with a minimum of 67 FPS, ensuring smooth gameplay without the visual degradation of Low settings. For players who demand 4K, the only option is Low at 43 FPS, but this is a compromise on both resolution and quality, and the game will still feel sluggish.

Measured FPS Breakdown

The complete dataset of measured frames per second is as follows:

1920x1080:

• Low: 96 FPS average
• Medium: 78 FPS average, 67 FPS minimum, 90 FPS maximum
• High: 64 FPS average
• Ultra: 40 FPS average

2560x1440:

• Low: 68 FPS average
• Medium: 56 FPS average, 48 FPS minimum, 64 FPS maximum
• High: 46 FPS average
• Ultra: 29 FPS average

3840x2160:

• Low: 43 FPS average
• Medium: 35 FPS average, 30 FPS minimum, 40 FPS maximum
• High: 29 FPS average
• Ultra: 18 FPS average

The 1080p Low result of 96 FPS is the only score above 90 FPS, and it represents the peak of this system’s capability. The 1080p Medium range (67-90 FPS) shows a wide variance, indicating that the game’s complexity varies significantly between scenes. The 1440p results show a clear drop, with the Low setting at 68 FPS being the only option above 60 FPS. The 4K results are uniformly poor, with the Medium setting’s minimum of 30 FPS being the playability floor.

The Ultra settings are consistently the worst, with a 58% drop from Low at the same resolution (96 to 40 FPS at 1080p; 68 to 29 FPS at 1440p; 43 to 18 FPS at 4K). This indicates that Ultra settings introduce effects that are disproportionately expensive for the Arc B370’s limited ROPs and memory bandwidth. The gap between Medium and High is smaller (14 FPS at 1080p, 10 FPS at 1440p, 6 FPS at 4K), suggesting that High is a moderate step up from Medium, but Ultra is a massive jump that the GPU cannot handle.

FAQ

*Q: Is this system capable of running Downfall at 60 FPS?*

A: Yes, but only at 1080p with Low settings, where it averages 96 FPS. At 1080p Medium, it averages 78 FPS, which is also above 60 FPS. No other resolution or settings combination achieves a 60 FPS average.

Q: What is the best settings preset for 1440p gaming?

A: The Low preset is the only viable option at 1440p, delivering 68 FPS. The Medium preset drops to 56 FPS with a minimum of 48 FPS, which is too inconsistent for smooth play.

Q: How does the Intel Arc B370 compare to its nearest rivals?

A: The Arc B370 scores 1184 in 3DMark Steel Nomad DX12, which is 0.2% lower than the ATI Mobility Radeon HD 5570 (1186) and 0.5% lower than the ATI Radeon HD 5770 (1190). It is 1.4% higher than the AMD FirePro M2000 (1168).

*Q: Does the CPU limit performance in Downfall?*

A: The data indicates the GPU is the primary bottleneck. The Ryzen 5 7600 has a strong single-thread score of 1852 in Cinebench R23 and 999 in 3DMark single-thread, but the frame rate drops are consistent with GPU load rather than CPU limitations.

Q: What is the expected frame rate at 4K Ultra?

A: The measured average is 18 FPS, which is unplayable. The 4K High setting averages 29 FPS, and the 4K Medium setting averages 35 FPS with a 30 FPS minimum.

Q: Why is the memory system-shared a problem for this game?

A: The Arc B370 uses system-shared memory, meaning it draws from the same DDR5 pool as the CPU. The Ryzen 5 7600 has a memory bandwidth of 83.2 GB/s, but this is shared, and Downfall’s high-resolution textures and framebuffer consume significant bandwidth, causing the steep FPS drops at 4K.

CPU Role

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael, built on TSMC’s 5 nm process. It has a base clock of 3.80 GHz and a boost clock of 5.10 GHz, with a TDP of 65 W. The cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. In Downfall, the CPU is not the limiting factor, but its performance characteristics still shape the results.

The CPU’s benchmark scores show strong single-threaded capability: 1852 in Cinebench R23 single-core, 999 in 3DMark single-thread, and 3910 in PassMark single-thread. These scores place it in the 78th percentile of all CPUs, with an average benchmark score of 26324. Its nearest rivals include the AMD Ryzen 9 6900HX (0.2% higher score), AMD Ryzen 7 7435HS (0.3% lower), and Intel Core i9-11900KF (0.4% higher). This single-thread strength means that Downfall, which likely relies on a few primary threads for game logic and rendering calls, will not be starved for CPU resources.

The multithreaded scores are also solid: 12735 in Cinebench R23 multicore and 13413 in GeekBench multicore. The 3DMark scores scale from 1938 for 2 threads to 6503 for max threads, showing good scaling across the 12 threads. However, the game’s frame rates are far below what this CPU can feed, confirming that the Arc B370 is the bottleneck. The CPU’s 32 MB L3 cache and dual-channel DDR5 memory support (83.2 GB/s bandwidth) are more than adequate for a 2016 horror title.

The CPU’s role in this pairing is to provide a stable platform for the GPU, and it does so without issue. The measured FPS does not show any signs of CPU stuttering or frame time spikes—the minimum FPS values (e.g., 48 FPS at 1440p Medium, 67 FPS at 1080p Medium) are consistent with GPU limitations rather than CPU hitches. The Ryzen 5 7600, with its 5.10 GHz boost clock and 6 cores, is a capable partner, but it cannot rescue the Arc B370 from its low-end position. Players seeking higher frame rates would need to upgrade the GPU, not the CPU, as the data clearly shows the graphics card is the constraint in every resolution and settings combination.
