Downfall

# Downfall with AMD Ryzen 5 4600G + AMD Radeon RX 9070

The pairing of AMD's Zen 2-based Ryzen 5 4600G with the RDNA 4.0 Radeon RX 9070 produces a striking split in Downfall's benchmark results. At 1080p, the system delivers frame rates from 122.7 FPS on Ultra to 294.7 FPS on Low, showcasing significant headroom. However, the scaling pattern across resolutions reveals a classic bottleneck shift, where the 6-core, 12-thread processor begins to limit performance at lower resolutions while the GPU takes over as the primary constraint at 4K. This analysis breaks down the measured FPS data, the roles of each component, and where this combination stands among 1,741 tested combos.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial but not linear across all settings. At Low settings, the average FPS falls from 294.7 at 1080p to 209.9 at 1440p, then to 131.2 at 4K — a reduction of 28.8% from 1080p to 1440p and another 37.5% from 1440p to 4K. This steep decline at Low settings indicates that the GPU is not the limiting factor at 1080p; the RX 9070, with its 16 GB of GDDR6 memory and 644.6 GB/s bandwidth, is capable of far higher output than the Ryzen 5 4600G can feed it.

At Ultra settings, the scaling tells a different story. The average FPS drops from 122.7 at 1080p to 87.8 at 1440p (a 28.4% decrease), then to 53.4 at 4K (a 39.2% decrease). The percentage drops are similar to Low settings, but the absolute values are much lower. This suggests that at Ultra, both components are being taxed heavily — the CPU must handle more draw calls and physics, while the GPU processes more complex shading and effects. The 4K Ultra result of 53.4 FPS is the only sub-60 FPS result in the entire dataset, indicating that this resolution/settings combination pushes the system past its comfort zone.

Medium settings show an intermediate pattern: 240.4 FPS at 1080p, 173.3 at 1440p, and 105.2 at 4K. The delta between 1080p and 1440p is 27.9%, while the 1440p to 4K drop is 39.3%. High settings follow a similar trend with 197.6, 140.6, and 88 FPS respectively. The consistency of these percentage drops across settings — roughly 28% for the first step and 39% for the second — reveals that the bottleneck shifts predictably with pixel count. At 1080p, the CPU's single-thread performance (726 in 3dmark_single_thread, 1,919 in cinebench_r23_singlecore) becomes the ceiling. At 4K, the GPU's raw throughput (36.13 TFLOPS FP32) is the determining factor.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor built on TSMC's 7 nm process, with a base clock of 3.70 GHz and boost clock of 4.20 GHz. It belongs to the 4000 series with the Renoir codename, featuring Zen 2 architecture. Its 8 MB of shared L3 cache is modest by modern standards, but its 51.2 GB/s dual-channel DDR4 memory bandwidth is adequate for most gaming workloads. The processor's 3dmark scores — 4,863 for 16 threads, 4,138 for 8 threads, and 726 for single-thread — paint a picture of a chip that scales decently with multi-threading but lacks the single-core punch of newer designs.

In Downfall, the CPU's role is most evident in the 1080p results. The jump from Low (294.7 FPS) to Medium (240.4 FPS) to High (197.6 FPS) to Ultra (122.7 FPS) at 1080p shows that the processor can maintain high frame rates but struggles to keep up with the GPU's potential at lower graphical loads. The 294.7 FPS Low result is likely near the CPU's practical ceiling for this title, as the GPU would be capable of far more at such light settings. The cinebench_r23_multicore score of 13,593 and passmark_multithread score of 15,992 indicate solid multi-threaded performance, but the single-thread scores — 1,919 in r23, 726 in 3dmark — are the limiting factor when the GPU isn't stressed.

The 4600G's nearest rivals, based on average benchmark scores, include the AMD Ryzen 3 PRO 5355GE (deltaPct 0), Intel Core i5-12450H (deltaPct 0.1), Intel Core i3-14100T (deltaPct -0.8), and Intel Core i3-13100F (deltaPct -1). These deltas are all within 1%, suggesting that the 4600G sits in a tightly contested performance tier. In gaming, however, the 4600G's lower single-thread performance compared to the i3 parts could be more consequential, especially in a horror title like Downfall where frame pacing and consistency matter for atmosphere.

GPU Role

The AMD Radeon RX 9070 is a substantial piece of hardware: 16 GB of GDDR6 on a 256-bit bus, 3,584 shading units, 224 TMUs, and 128 ROPs. Its boost clock of 2520 MHz and game clock of 2070 MHz, combined with 56 ray tracing cores, place it firmly in the high-end segment. The GPU's 3dmark Steel Nomad DX12 score of 6,290 and passmark G3D score of 25,381 demonstrate strong synthetic performance, while its 79th percentile ranking among all GPUs confirms its position.

In Downfall, the GPU's dominance is clear at 4K. Even at High settings, the system maintains 88 FPS, and at Medium it reaches 105.2 FPS. The 4K Low result of 131.2 FPS shows that the RX 9070 has ample raw power for this title at high pixel counts. The GPU's 644.6 GB/s memory bandwidth and 322.6 GPixel/s pixel rate are particularly relevant for 4K rendering, where texture fetch and pixel fill become bottlenecks for lesser cards.

The RX 9070's nearest rivals, based on average benchmark scores, are the NVIDIA A2 (deltaPct -0.2), NVIDIA Quadro GV100 (deltaPct 0.3), AMD Radeon HD 7970 (deltaPct 0.7), and AMD Radeon PRO W6400 (deltaPct 0.8). These comparisons are based on aggregate benchmarks, not gaming-specific performance. In Downfall, the RX 9070's 16 GB VRAM and modern architecture likely give it an edge over older or workstation-oriented cards that might have similar synthetic scores but lack gaming optimizations.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings tiers. At 1920x1080, the system delivers 294.7 FPS on Low, 240.4 FPS on Medium, 197.6 FPS on High, and 122.7 FPS on Ultra. These are all highly playable numbers, with even the Ultra result exceeding 120 FPS. The difference between Low and Ultra at 1080p is 172 FPS, or 58.4% — a massive gap that highlights how much headroom exists at this resolution.

Moving to 2560x1440, the numbers drop to 209.9 FPS on Low, 173.3 FPS on Medium, 140.6 FPS on High, and 87.8 FPS on Ultra. The Ultra result dips below 90 FPS, which is still smooth for most displays but shows the increased load. The gap between Low and Ultra at 1440p is 122.1 FPS, or 58.2% — nearly identical to the 1080p percentage, indicating that the relative performance scaling is consistent.

At 3840x2160, the results are 131.2 FPS on Low, 105.2 FPS on Medium, 88 FPS on High, and 53.4 FPS on Ultra. The Ultra setting falls below 60 FPS, which may be noticeable in a horror game where smooth motion is critical for immersion. The Low-to-Ultra gap at 4K is 77.8 FPS, or 59.3% — again, a similar percentage, confirming that the CPU-GPU balance scales proportionally with resolution. The 4K Ultra result of 53.4 FPS is the only tier where the system fails to maintain 60 FPS, making it the key consideration for players with 4K displays who want maximum visual fidelity.

How This Combo Ranks

The Ryzen 5 4600G + RX 9070 combination ranks 572nd out of 1,741 tested combos in Downfall, placing it in the 67th percentile of all systems tested. This is a respectable position, but it reflects the CPU's limitations more than the GPU's capabilities. Given that the RX 9070 alone ranks in the 79th percentile among GPUs, the combo's lower rank suggests the 4600G is holding back the system's overall gaming performance.

The rank of 572 out of 1,741 means that roughly 1,169 combos perform better in this game. However, it's important to consider that many of those higher-ranked combos likely feature more powerful CPUs paired with similar or better GPUs. The 4600G's single-thread score of 726 in 3dmark and 1,919 in cinebench r23 are the likely culprits for the rank deficit, as Downfall appears sensitive to CPU throughput based on the 1080p scaling data.

For context, the combo sits in the upper third of all tested systems, which is a solid result for a mid-range CPU paired with a high-end GPU. The data suggests that upgrading the processor to something with stronger single-thread performance would yield meaningful gains at 1080p and 1440p, while the 4K results would remain largely unchanged since the GPU becomes the bottleneck there. The 53.4 FPS Ultra 4K result is the system's weakest showing, and it's primarily a GPU limitation given the RX 9070's 36.13 TFLOPS FP32 throughput being taxed by the title's heavy settings. Overall, this combo delivers strong performance for most use cases, with the caveat that CPU-bound scenarios at lower resolutions will not fully utilize the RX 9070's potential.
