How This Combo Ranks

The combo's rank of 2889 out of 3716 tested combinations places it in the 22nd percentile of all tested systems for Downfall. This low ranking is not a reflection of weak components individually—the CPU's average benchmark score of 37943 puts it in the 86th percentile of all CPUs, while the GPU's average score of 19036 places it in the 63rd percentile of all GPUs. Rather, the ranking reflects how the game responds to this specific hardware pairing, where the GPU's mid-range position becomes the dominant factor.

The CPU's nearest rivals illustrate its strong synthetic performance. The AMD Ryzen 7 9700X scores just 0.1% above the Intel Core i9-14901E (37911) and 0.1% above the AMD Ryzen AI 9 HX 370 (37904), with a 0.3% lead over the Intel Core 5 211E (37829) and 0.4% over the AMD Ryzen AI Embedded P132 (37804). These margins are negligible, indicating the 9700X is firmly positioned in a competitive cluster of high-end processors.

For the GPU, the AMD Radeon RX 6600 sits in a tight grouping as well. It matches the NVIDIA Quadro K6000 (19030) at a 0% delta, trails the NVIDIA GeForce RTX 4050 Mobile (19049) by 0.1%, and leads both the NVIDIA Tesla K20m (19089) and NVIDIA RTX 2000 Ada Generation (18954) by 0.3% and 0.4% respectively. These near-identical scores mean the RX 6600's positioning in Downfall is determined by game-specific optimization rather than raw compute potential.

Given that the CPU outperforms the GPU in their respective percentile standings by 23 points, the data suggests that a more balanced GPU would likely improve this combo's rank substantially. The measured FPS confirms this interpretation, as even at 1080p the GPU is unable to fully utilize the CPU's capabilities.

FAQ

Q: Is this combo better suited for 1080p or 4K gaming in Downfall?

A: The data shows playable performance at 1080p across all settings, while 4K becomes marginal. At 1080p Medium, the combo delivers 143 average FPS, but at 4K Ultra it drops to 33 average FPS, indicating the GPU cannot sustain high frame rates at higher resolutions.

Resolution Scaling

The FPS progression from 1080p to 4K reveals a GPU-bound scenario at all resolutions. At Low settings, the combo delivers 175 FPS at 1080p, 125 FPS at 1440p, and 78 FPS at 4K. This represents a 29% drop from 1080p to 1440p and a 55% drop from 1440p to 4K. The scaling pattern indicates the GPU is the limiting component, as the CPU's high single-thread performance (1280 in 3DMark single-thread) would not bottleneck at these frame rates.

At Medium settings, the pattern continues: 143 FPS at 1080p, 102 FPS at 1440p, and 64 FPS at 4K. The 4K result includes a min FPS of 54 and max of 73, showing noticeable frame-time variance. The drop from 1440p to 4K is 37%, which is consistent with a GPU that has only 8 GB of VRAM and 224.0 GB/s bandwidth struggling with higher pixel counts.

High settings show a similar trend: 117 FPS at 1080p, 84 FPS at 1440p, and 52 FPS at 4K. The 1440p to 4K drop is 38%, nearly identical to the Medium setting's drop. This consistency suggests the GPU's memory bandwidth, not its compute units, is the primary constraint at higher resolutions.

Ultra settings reveal the steepest scaling: 73 FPS at 1080p, 52 FPS at 1440p, and 33 FPS at 4K. The 1080p to 1440p drop is 29%, and the 1440p to 4K drop is 37%. The 4K Ultra result of 33 FPS is below playable thresholds for most users, confirming that this combo is not viable at maximum settings in 4K.

The CPU's role in this scaling is minimal. With a boost clock of 5.50 GHz and 3DMark 16-thread score of 9824, the 9700X can easily feed the GPU at all tested resolutions. The bottleneck is consistently the RX 6600, whose 8.928 TFLOPS FP32 performance and 159.4 GPixel/s pixel rate are exhausted by higher resolutions.

Measured FPS Breakdown

1920x1080 (1080p):

• Low: 175 average FPS
• Medium: 143 average FPS (min 122, max 164)
• High: 117 average FPS
• Ultra: 73 average FPS

At 1080p, all settings deliver playable frame rates. The jump from Low to Medium is a 18% reduction, Medium to High is 18%, and High to Ultra is 38%. The Ultra setting's 73 FPS is still smooth, making 1080p the sweet spot for this combo.

2560x1440 (1440p):

• Low: 125 average FPS
• Medium: 102 average FPS (min 87, max 117)
• High: 84 average FPS
• Ultra: 52 average FPS

1440p shows a clear degradation. Low and Medium remain playable, but High drops to 84 FPS and Ultra to 52 FPS. The Medium settings' min FPS of 87 indicates occasional frame drops, while Ultra's 52 average may feel inconsistent in fast-paced scenes.

3840x2160 (4K):

• Low: 78 average FPS
• Medium: 64 average FPS (min 54, max 73)
• High: 52 average FPS
• Ultra: 33 average FPS

4K is only viable at Low and Medium settings. The 78 FPS at Low is acceptable, but Medium's 64 FPS with a 54 FPS minimum approaches the edge of playability. High at 52 FPS is marginal, and Ultra at 33 FPS is not recommended.

The pattern across all resolutions is consistent: Medium settings provide the best balance of visual quality and performance, with a 23% reduction from Low at 1080p, 18% at 1440p, and 18% at 4K. Ultra settings impose a disproportionate penalty, with the largest relative drops at all resolutions.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, manufactured on a 7 nm process at TSMC with 11,060 million transistors on a 237 mm² die. Its 1792 shading units, 112 texture mapping units, and 64 ROPs provide the compute foundation for Downfall's rendering. The GPU's 28 ray tracing cores support the game's horror visuals, though the game's performance suggests rasterization is the primary workload.

The GPU's clock behavior is notable: a base clock of 1626 MHz, game clock of 2044 MHz, and boost clock of 2491 MHz. The 408 MHz difference between base and boost indicates aggressive power management, with the 132W TDP allowing sustained boost under load. The 8 GB of GDDR6 memory operates at 1750 MHz (14 Gbps effective) across a 128-bit bus, yielding 224.0 GB/s bandwidth. This bandwidth is likely the limiting factor at 4K, as the 128-bit bus is narrow for high-resolution textures.

The GPU's 3DMark Steel Nomad DX12 score of 1492 and PassMark G3D score of 15096 place it in the 63rd percentile of all GPUs. Its nearest rivals—the NVIDIA Quadro K6000, RTX 4050 Mobile, Tesla K20m, and RTX 2000 Ada Generation—all score within 0.4% of the RX 6600, confirming its mid-range position. In Downfall, this translates to 52 FPS at 4K High and 33 FPS at 4K Ultra, indicating the GPU cannot handle the game's most demanding settings.

The GPU's FP32 performance of 8.928 TFLOPS and texture rate of 279.0 GTexel/s are sufficient for 1080p gaming but stretch at higher resolutions. The pixel rate of 159.4 GPixel/s directly impacts fill-rate-bound scenes, and the 64 ROPs are modest for 4K workloads. The PCIe 4.0 x8 interface provides 8 lanes of bandwidth, which is adequate for this GPU class but not excessive.

CPU Role

The AMD Ryzen 7 9700X is a Zen 5 architecture processor (Granite Ridge codename) built on TSMC's 4 nm process with 8,315 million transistors on a 70.6 mm² die. Its 8 cores and 16 threads run at a base clock of 3.80 GHz and boost to 5.50 GHz, with a 65W TDP that allows the CPU to maintain high clocks without excessive power draw. The 4 nm process node gives it a significant efficiency advantage over older designs.

The CPU's cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. This configuration supports the 89.6 GB/s dual-channel DDR5 memory bandwidth, which is ample for feeding the GPU in Downfall. The CPU's 3DMark scores show strong scaling: 1280 single-thread, 2525 for 2 threads, 4869 for 4 threads, 8184 for 8 threads, and 9771 for max threads. This near-linear scaling up to 8 threads indicates the Zen 5 architecture efficiently utilizes all cores.

In synthetic benchmarks, the 9700X achieves 2211 in Cinebench R23 single-core and 20485 in multi-core, with Geekbench scores of 3023 single-core and 17906 multi-core. Its PassMark multi-thread score of 37161 and single-thread score of 4654 place it in the 86th percentile of all CPUs. The nearest rivals—Intel Core i9-14901E, AMD Ryzen AI 9 HX 370, Intel Core 5 211E, and AMD Ryzen AI Embedded P132—are all within 0.4% of the 9700X's average score of 37943.

Despite this CPU strength, the measured FPS in Downfall never exceeds 175 at 1080p Low, which is well below the CPU's potential frame generation capability. The bottleneck is clearly the GPU, as the CPU's 5.50 GHz boost clock and 16 threads can easily handle the game's logic and physics at all tested settings. The CPU's 65W TDP and AM5 socket also allow for overclocking (multiplier unlocked), though the stock performance is already sufficient for this game.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and frame rate preference.

For 1080p (1920x1080): Ultra settings at 73 average FPS provide an excellent experience, as the frame rate remains above 60 FPS. If higher frame rates are preferred, High at 117 FPS offers a 60% improvement over Ultra with minimal visual degradation. Medium at 143 FPS is the best choice for competitive play, with a minimum FPS of 122 ensuring smooth performance. Low at 175 FPS is unnecessary unless chasing maximum refresh rates.

For 1440p (2560x1440): High settings at 84 average FPS are the recommended starting point, providing good visual fidelity with playable performance. Medium at 102 FPS is a strong alternative if frame rate consistency is prioritized, with a minimum FPS of 87. Ultra at 52 FPS is borderline and should only be used in slower-paced sections. Low at 125 FPS is viable for high-refresh monitors but sacrifices visual quality.

For 4K (3840x2160): Low settings at 78 average FPS are the only fully playable option, offering a smooth experience for the game's horror atmosphere. Medium at 64 FPS (min 54) is playable but may exhibit occasional stutter. High at 52 FPS is marginal and not recommended for extended sessions. Ultra at 33 FPS is not viable for gameplay.

The data indicates that Medium settings provide the most balanced experience across all resolutions, with an average FPS of 143 at 1080p, 102 at 1440p, and 64 at 4K. The 1080p Medium result includes a narrow frame-time spread (min 122, max 164), suggesting consistent performance. For users prioritizing visual quality, High settings at 1080p (117 FPS) or 1440p (84 FPS) offer the best compromise, while 4K users should stick to Low settings to maintain playability. The GPU's 8 GB VRAM and 224.0 GB/s bandwidth are adequate for 1080p and 1440p at Medium-to-High settings, but the 4K results show that the combo is not designed for that resolution in Downfall.
