Q: Is the CPU or GPU the limiting factor in this game?

A: The data clearly shows the GPU is the limiting factor. The Arc B370 has only 6.144 TFLOPS of FP32 compute, 1280 shading units, and 20 ROPs, with its 5th percentile GPU rank. The CPU's 71st percentile ranking among all processors shows it has relatively more headroom, though the shared memory architecture of the GPU creates a system-level constraint.

GPU Role

The Intel Arc B370 is the dominant constraint in this configuration for Downfall. Its benchmark score of 1184 in 3DMark Steel Nomad DX12 places it at the 5th percentile of all GPUs, with nearest rivals being legacy cards like the ATI Radeon HD 5770 (1190) and ATI Mobility Radeon HD 5570 (1186). The deltaPct values are extremely tight—within 1.4%—meaning the B370 essentially performs on par with these older GPUs, which explains its limited ability to handle modern horror titles.

The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, which is a wide range typical of an integrated graphics processor. The Arc B370 uses system shared memory with system-dependent bandwidth, a design that ties memory performance to the host CPU's DDR4 memory subsystem. The Ryzen 5 4600G supports DDR4-3200 dual-channel memory with 51.2 GB/s bandwidth, which is the practical memory ceiling for the GPU. This shared memory architecture directly explains the frame rate collapses at higher resolutions and settings, as the GPU must compete with the CPU for the same memory bandwidth.

With only 1280 shading units, 40 texture mapping units, and 20 ROPs, the B370 is a very small GPU die. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are modest figures, and the FP32 throughput of 6.144 TFLOPS is low by modern standards. The 10 ray tracing cores are present, but with this low base performance, ray-traced effects would be impractical in Downfall. The GPU's 25 W TDP and integrated form factor (IGP) confirm this is designed for portable or low-power systems, not for high-refresh gaming.

The measured FPS data underscores this GPU limitation. At 1080p Low, the B370 manages 96 FPS, but that is the peak. At 1080p Ultra, the frame rate collapses to 40 FPS—a 58% drop from Low to Ultra at the same resolution. The GPU's 5th percentile rank means it outperforms only a small fraction of the tested GPUs, and its nearest rivals are all older ATI/AMD parts from a different era. The 3DMark Steel Nomad DX12 score of 1184 is the only GPU benchmark recorded, and it confirms the B370 is a low-end part for this game.

CPU Role

The AMD Ryzen 5 4600G provides the compute foundation for this combo, and the data shows it is not the primary bottleneck in Downfall. The CPU ranks at the 71st percentile among all tested CPUs, with an average benchmark score of 17507. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE (17482, 0.1% slower) and the AMD Ryzen 3 8300GE (17614, 0.6% faster), while the Intel Core 7 150U (17395, 0.6% slower) and Intel Core i3-14100T (17648, 0.8% faster) bracket it. These small deltaPct values indicate the 4600G is a mid-pack CPU, with its 6 cores and 12 threads running at a base clock of 3.70 GHz and boost up to 4.20 GHz.

The 4000 series processor is built on the Zen 2 architecture with a 7 nm process from TSMC, using the Renoir codename. It has 9,800 million transistors on a 156 mm² die, with 64 KB L1 and 512 KB L2 cache per core, plus 8 MB of shared L3 cache. In multi-threaded workloads, the CPU scores 13593 in Cinebench R23 multi-core and 5709 in Cinebench R20 multi-core, while single-thread scores reach 1919 and 805 respectively. The Geekbench multi-core score is 6637 and single-core is 1460. These numbers show the CPU is competitive in its class, but the GPU's low percentile rank means the CPU has headroom that the GPU cannot exploit.

The 4600G also includes Radeon Vega 7 integrated graphics, but in this combo the discrete Intel Arc B370 is used. The CPU's 65W TDP and AM4 socket with Gen 3 PCIe (20 lanes) provide a reasonable platform. The memory bandwidth of 51.2 GB/s is shared with the GPU, which is a critical interaction. In Downfall, the game's horror genre likely relies on consistent frame pacing and lighting effects, but the CPU's strong multi-threaded scores (e.g., 13593 in Cinebench R23) suggest it can handle game logic and AI without being the primary constraint.

The percentile data makes this clear: the CPU is in the top 29% of all CPUs, while the GPU is in the bottom 5%. The benchmark results show the CPU delivers high scores relative to its peers, but the GPU's 3DMark score is near the bottom of all GPUs. Thus, for Downfall, the CPU is sufficient, and the performance ceiling is set by the graphics subsystem.

How This Combo Ranks

The combo rank of 3429 out of 3716 tested combinations places this configuration in the 7.7% worst of all tested. The data shows this is a severely GPU-bound pairing, as the CPU's 71st percentile rank contrasts with the GPU's 5th percentile. In a game like Downfall, which has a horror genre and a release date of 2016-02-28, the demands on the GPU are clear from the measured FPS data. The rank of 3429 means that out of 3716 tested combos, this system is faster than only 287 combos, which is a very small fraction.

The nearest GPU rivals provide context: the ATI Radeon HD 5770 (1190) and ATI Mobility Radeon HD 5570 (1186) are within 0.5% of the Arc B370's score, and the AMD Radeon HD 7650M (1192) is 0.7% faster. These are all legacy GPUs from the early 2010s, so the B370 is effectively at that performance level. The combo rank reflects this, as the system is grouped with much older hardware in the overall ranking.

The CPU's nearest rivals are also informative. The AMD Ryzen 3 PRO 5355GE (17482) and Intel Core 7 150U (17395) are within 0.6% of the 4600G's average score, meaning the CPU is not the reason for the low rank. If the GPU were swapped for a stronger part, the CPU would likely allow a much higher combo rank, but the data only measures this specific pairing. The 0.1% deltaPct to the PRO 5355GE and the 0.6% to the Core 7 150U show the CPU is in a tight performance cluster, but the GPU's low rank dominates the combo's position.

Resolution Scaling

The resolution scaling shows a clear pattern of GPU bottlenecking. At 1920x1080, the system produces playable frame rates on Low (96 FPS), Medium (78 FPS), and High (64 FPS), but Ultra drops to 40 FPS. Moving to 2560x1440, the frame rates fall to 68 FPS at Low, 56 FPS at Medium, 46 FPS at High, and 29 FPS at Ultra. At 3840x2160, the system manages only 43 FPS at Low, 35 FPS at Medium, 29 FPS at High, and 18 FPS at Ultra.

The percentage drops from 1080p to 4K reveal the limiting component. At Low settings, the FPS drops from 96 to 43, a 55% reduction. At Medium, the drop is from 78 to 35, a 55% reduction. At High, the drop is from 64 to 29, a 55% reduction. At Ultra, the drop is from 40 to 18, a 55% reduction. The consistency of the 55% drop across all settings indicates that the GPU is the primary bottleneck, as the CPU's performance does not change with resolution, and the GPU's fillrate and memory bandwidth are insufficient at higher pixel counts.

The data also shows that the gap between settings widens with resolution. At 1080p, the difference between Low and Ultra is 56 FPS (96 vs 40). At 1440p, the gap is 39 FPS (68 vs 29). At 4K, the gap is 25 FPS (43 vs 18). This narrowing gap suggests that at 4K, even the lowest settings are hitting a hard GPU limit, and the settings change provides diminishing returns. The 4K Low score of 43 FPS and 4K Ultra score of 18 FPS are both below the 60 FPS target, so this system is not suitable for 4K gaming in Downfall.

The CPU's 51.2 GB/s memory bandwidth is shared with the GPU, so at higher resolutions, the memory subsystem becomes even more stressed. The GPU's system-shared memory with "System Dependent" bandwidth means the effective GPU memory bandwidth is tied to the CPU's DDR4-1280 dual-channel bandwidth, which is a major limitation at 4Kp. The data shows that 1080p Low is the only setting that achieves 60 FPS or above, and even then, the 96 FPS average is the sole triple-digit result.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's performance in Downfall across all settings and resolutions.

1920x1080 (1080p):

• Low: 96 FPS average. This is the best result for this combo, achieving near triple-digit performance.
• Medium: 78 FPS average, with a minimum of 67 FPS and maximum of 90 FPS. This is a comfortable frame rate for most users.
• High: 64 FPS average. This is still playable, but the drop from Medium is 14 FPS.
• Ultra: 40 FPS average. This is a 40 FPS drop from Low, showing the heavy cost of Ultra settings.

2560x1440 (1440p):

• Low: 68 FPS average. A 28 FPS drop from 1080p Low, but still above 60 FPS.
• Medium: 56 FPS average, with a minimum of 48 FPS and maximum of 64 FPS. The average is below 60 FPS.
• High: 46 FPS average. The gap from Low to High is 22 FPS.
• Ultra: 29 FPS average. This is below 30 FPS, making it nearly unplayable.

3840x2160 (4K):

• Low: 43 FPS average. This is the only 4Kp setting above 40 FPS.
• Medium: 35 FPS average, with a minimum of 30 FPS and maximum of 40 FPS. The average is 35 FPS, which is borderline.
• High: 29 FPS average. This is a 14 FPS drop from 4Kp Low.
• Ultra: 18 FPS average. This is the worst result, at 18 FPS.

The data shows that the system is only viable at 1080p with Low or Medium settings, and at 1440p with Low settings. The 1080p Medium average of 78 FPS with a minimum of 67 FPS is the most playable configuration for a consistent experience. The 1080p High average of 64 FPS is also acceptable, but the Ultra setting at 40 FPS is marginal. At 1440p, only Low (68 FPS) achieves 60 FPS, while Medium (56 FPS) and High (46 FPS) are below that. At 4Kp, all settings are below 45 FPS, and the 4Kp Ultra of 18 FPS is far below playable. The maximum FPS values are only recorded for the Medium settings, showing a 90 FPS peak at 1080p, 64 FPS at 1440p, and 40 FPS at 4Kp. The minimum FPS values are also only recorded for Medium settings, with 67 FPS at 1080p, 48 FPS at 1440p, and 30 FPS at 4Kp. These numbers highlight the frame rate collapse as resolution increases, with the GPU being the limiting factor.
