Downfall

Resolution Scaling

The measured FPS data for Downfall with the AMD Ryzen 7 5700G and NVIDIA GeForce RTX 4090 reveals a clear progression from 1080p to 4K, with the GPU becoming the dominant limiting factor at higher resolutions. At 1920x1080 with Ultra settings, the combo delivers 184.2 FPS, which drops to 132.7 FPS at 2560x1440 and further to 83.7 FPS at 3840x2160. This represents a 54.6% reduction in frame rate from 1080p Ultra to 4K Ultra, a substantial penalty that indicates the RTX 4090 is being increasingly taxed as pixel count grows.

The scaling pattern differs noticeably across settings tiers. At Low settings, the frame rate falls from 367.2 FPS at 1080p to 314.5 FPS at 1440p and 197.2 FPS at 4K — a 46.3% drop from the lowest to highest resolution. At Medium settings, the decline goes from 340.6 FPS at 1080p to 260.3 FPS at 1440p and 164.1 FPS at 4K, a 51.8% reduction. High settings show 294.5 FPS at 1080p, 210.2 FPS at 1440p, and 134.9 FPS at 4K, a 54.2% decrease.

The data suggests that at 1080p, the Ryzen 7 5700G's eight cores and 16 threads are capable of feeding the RTX 4090 adequately, especially at lower settings where the frame rates exceed 300 FPS. The CPU's 3.80 GHz base clock and 4.60 GHz boost clock provide sufficient single-thread performance for this horror title. However, the frame rate differences between Low and Ultra at 1080p (367.2 FPS versus 184.2 FPS) indicate that the GPU's workload scales significantly with visual fidelity, even at lower pixel counts.

At 4K, the picture changes dramatically. The difference between Low (197.2 FPS) and Ultra (83.7 FPS) settings is 113.5 FPS, showing that the RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are being pushed hard. The 4K Ultra result of 83.7 FPS is the only measured frame rate below 100 FPS, suggesting that this resolution and settings combination is where the GPU becomes the clear bottleneck.

FAQ

Q: What is the best resolution for this CPU-GPU combo in Downfall?

A: The data shows that 2560x1440 offers the best balance, with High settings producing 210.2 FPS and Ultra reaching 132.7 FPS. At 1920x1080, frame rates exceed 294 FPS on High, but the 1440p results remain well above 60 FPS while providing higher visual clarity.

Q: How does the RTX 4090 perform at 4K Ultra settings in this game?

A: At 3840x2160 with Ultra settings, the combo delivers 83.7 FPS average. This is the lowest measured result across all configurations but remains playable. The frame rate drops significantly from the 132.7 FPS seen at 1440p Ultra, indicating a 36.9% performance penalty from the resolution increase.

Q: Is the Ryzen 7 5700G holding back the RTX 4090 in Downfall?

A: Benchmark results indicate that at 1080p with Low settings (367.2 FPS), the CPU may be limiting performance, as the GPU is likely capable of higher frame rates. However, at 4K Ultra (83.7 FPS), the GPU is the clear bottleneck. The CPU's 16 threads and 4.60 GHz boost clock appear sufficient for most configurations.

Q: What settings tier provides the largest performance gap?

A: The difference between Low and Ultra settings is most pronounced at 1440p, where frame rates range from 314.5 FPS to 132.7 FPS — a gap of 181.8 FPS. At 1080p, the gap is 183.0 FPS (367.2 to 184.2), and at 4K it is 113.5 FPS (197.2 to 83.7).

Q: How does this combo rank among tested configurations?

A: The combo ranks 53rd out of 1,741 tested combinations in Downfall, placing it in the top 3% of all tested setups. This high ranking reflects the strong performance of the RTX 4090, which sits in the 91st percentile among all GPUs.

Q: Can this setup maintain high refresh rates at 1440p?

A: Yes, the data shows that at 2560x1440, even Ultra settings produce 132.7 FPS, which exceeds the refresh rate of most high-refresh monitors. At High settings, the 210.2 FPS result offers ample headroom for 144Hz or 165Hz displays.

CPU Role

The AMD Ryzen 7 5700G is a desktop processor from the 5000 series, built on the Zen 3 architecture with the Cezanne codename. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. The CPU's 7 nm process node from TSMC houses 10,700 million transistors on a 180 mm² die. This processor's 16 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide the memory subsystem needed for gaming workloads.

In Downfall, the CPU's role varies by resolution. At 1920x1080 with Low settings, the 367.2 FPS result suggests that the CPU is the primary limiting factor, as the GPU could likely push higher frame rates if the processor could keep up. The CPU's single-thread performance, evidenced by a 3DMark single-thread score of 899 and a Cinebench R23 single-core score of 2,930, becomes critical at these high frame rates. The multi-thread performance, with a Cinebench R23 multi-core score of 20,755, provides adequate headroom for background tasks while gaming.

The Ryzen 7 5700G's 3DMark scores demonstrate its scaling characteristics: 2 threads yield 1,758, 4 threads produce 3,389, 8 threads reach 5,648, and 16 threads achieve 6,629. This near-linear scaling up to 8 threads indicates that the processor can effectively utilize its core count, though Downfall's performance at 1080p Low suggests that the game's threading model may not fully exploit all 16 threads. The CPU's 83rd percentile ranking among all processors places it above most desktop CPUs, though its nearest rivals include the AMD Ryzen 7 6800U with a 0.3% lower average score and the Intel Xeon D-2752TER with a 0.4% higher score.

The integrated Radeon Vega 8 graphics are present but irrelevant to this configuration, as the discrete RTX 4090 handles all rendering. The CPU's PCIe Gen 3 interface with 16 lanes provides the connection to the GPU, though the RTX 4090's PCIe 4.0 x16 bus interface may be slightly constrained by the older standard.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700G and NVIDIA GeForce RTX 4090 ranks 53rd out of 1,741 tested combos in Downfall, placing it in the top 3.0% of all configurations. This ranking is notable given that the CPU is a mid-range processor from 2021, while the GPU is a flagship from 2022 with a 91st percentile ranking among all GPUs.

The high ranking suggests that Downfall is predominantly GPU-bound at most settings, allowing the RTX 4090 to demonstrate its full capabilities despite the Ryzen 7 5700G's more modest CPU performance. The GPU's average benchmark score of 66,473 places it among the top tier, with nearest rivals including the NVIDIA Tesla T4 (0.4% lower score), NVIDIA Tesla P40 (0.5% higher score), and AMD Radeon Pro Vega 56 (0.9% lower score). These comparisons are based on aggregate benchmarks, not game-specific performance.

The CPU's contribution to this ranking is more nuanced. With an average benchmark score of 25,626, the Ryzen 7 5700G sits in the 83rd percentile, with rivals like the AMD Ryzen 7 6800U (0.3% lower), Intel Xeon D-2752TER (0.4% higher), and Intel Core 5 210H (0.5% higher) providing similar aggregate performance. In a game like Downfall, where frame rates at 1080p Low reach 367.2 FPS, the CPU's single-thread performance becomes critical, but the overall ranking indicates that the GPU dominates the performance equation.

The 53rd rank out of 1,741 combos means that 52 configurations achieve higher frame rates in Downfall, likely featuring more powerful CPUs paired with the RTX 4090 or similar flagship GPUs. However, the gap between this combo and the top-ranked configurations is likely small given the GPU's dominance in this title.
