Downfall

Resolution Scaling

The measured frame rates across the three resolutions reveal a classic scaling pattern that shifts the bottleneck depending on the settings preset. At 1080p with Low settings, the combo reaches 312 FPS, and dropping to 1440p Low yields 223 FPS — a reduction of 28.5%. Moving from 1440p to 4K Low further reduces performance to 139 FPS, another 37.7% drop. This steep decline at the lower preset indicates that the CPU is capable of feeding frames at a very high rate, but the GPU workload increases substantially as pixel count grows.

For the Medium preset, the scaling is more linear. From 1080p Medium at 255 FPS, the 1440p result is 182 FPS (a 28.6% reduction), and the 4K result is 113 FPS (a 37.9% reduction from 1440p). The High preset shows a similar pattern: 209 FPS at 1080p, 150 FPS at 1440p (down 28.2%), and 93 FPS at 4K (down 38.0%). These consistent percentage drops across Medium and High suggest that the game is scaling predictably with resolution, and neither component is being saturated to the point of creating a disproportionate penalty.

The Ultra preset presents an interesting anomaly. At 1080p Ultra, the average is 131 FPS; at 1440p Ultra, it drops to 93 FPS (a 29.0% reduction); and at 4K Ultra, it falls to 58 FPS (a 37.6% reduction from 1440p). The relative scaling is similar to other presets, but the absolute frame rates are much lower, indicating that Ultra settings impose a heavy rendering cost that the GPU cannot offset even at lower resolutions. The data suggests that the limiting component shifts from the CPU at low settings and resolutions to the GPU at high settings and resolutions. At 1080p Low, the 312 FPS result is likely near the CPU's practical ceiling for this game, while the 4K Ultra result of 58 FPS is clearly GPU-bound, as the pixel throughput demand overwhelms the Radeon RX 9070 XT's capabilities.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture (Vermeer codename), built on TSMC's 7 nm process. Its base clock is 3.80 GHz with a boost clock of 4.80 GHz. The processor has a 32 MB shared L3 cache, with 64 KB L1 and 512 KB L2 per core. Memory support is DDR4 with dual-channel configuration, providing 51.2 GB/s of bandwidth. The CPU supports PCIe Gen 4 with 20 lanes.

Benchmark data for the 5800XT shows strong multi-threaded performance: Cinebench R23 multi-core scores 23,794, while single-core scores 3,359. The 3DMark tests indicate scaling from 1,879 (2 threads) to 7,683 (16 threads), with 8-thread performance at 6,141 and max-thread at 7,680. PassMark multi-thread score is 28,053, and single-thread is 3,535. The processor ranks in the 81st percentile against all CPUs, with an average benchmark score of 29,879.

In the context of Downfall, the CPU's role is primarily to feed the GPU with draw calls and game logic. The measured FPS at 1080p Low (312) demonstrates that the 5800XT can sustain very high frame rates, which is consistent with its strong single-thread performance (3,359 in Cinebench R23 single-core). The 16 threads provide headroom for background tasks and any multi-threaded game systems, though the 3DMark data shows diminishing returns beyond 8 threads (6,141 vs 7,680 at max threads, a 25% gain for doubling thread count). The nearest rivals in synthetic benchmarks include the AMD Ryzen 7 7840H (average score 29,868, delta 0%) and the AMD Ryzen 7 8845HS (29,955, delta -0.3%), indicating that the 5800XT is squarely in the mid-range of modern desktop processors.

For Downfall specifically, the CPU appears sufficient to avoid being the primary bottleneck at higher resolutions. At 4K Ultra, the frame rate drops to 58 FPS, which is far below what the CPU could deliver, confirming that the GPU is the limiting factor there. Conversely, at 1080p Low, the 312 FPS result likely approaches the CPU's rendering limit, as the GPU has less work per frame and the processor's single-thread performance becomes more relevant.

Measured FPS Breakdown

At 1920x1080, the results span from 131 FPS at Ultra to 312 FPS at Low. The Medium preset averages 255 FPS with a minimum of 217 and maximum of 294. High settings at this resolution average 209 FPS. The progression from Low to Ultra shows a steady decline in performance, with Ultra being 58% slower than Low (312 vs 131 FPS).

Moving to 2560x1440, the averages are 223 FPS at Low, 182 FPS at Medium (minimum 155, maximum 210), 150 FPS at High, and 93 FPS at Ultra. The transition from 1080p to 1440p costs between 27% (Low: 312 to 223, a 28.5% drop) and 29% (Ultra: 131 to 93, a 29.0% drop) of performance, which is consistent with the increase in pixel count.

At 3840x2160, the averages drop further: 139 FPS at Low, 113 FPS at Medium (minimum 96, maximum 131), 93 FPS at High, and 58 FPS at Ultra. The 4K Ultra result of 58 FPS is the only measured result below 60 FPS, which is notable for a game that can otherwise run at high frame rates. The Medium preset at 4K shows a minimum of 96 FPS, suggesting that even the most demanding frame times stay above 90 FPS when not using the highest settings.

Across all measured data points, the scaling from 1080p to 4K at the same settings consistently reduces performance by roughly 55-56%. For example, Low drops from 312 to 139 (a 55.4% reduction), Medium from 255 to 113 (55.7%), High from 209 to 93 (55.5%), and Ultra from 131 to 58 (55.7%). This uniformity indicates that the game's rendering workload scales proportionally with pixel count, and the combo's performance is predictable across resolutions.

How This Combo Ranks

The AMD Ryzen 7 5800XT combined with the AMD Radeon RX 9070 XT achieves a rank of 910 out of 3,716 tested configurations in Downfall. This places the combo in the 75.5th percentile of all tested combos, meaning it outperforms roughly three-quarters of the configurations tested for this game. The rank of 910 indicates that while this is not a top-tier setup, it is well above the median and capable of delivering smooth gameplay at most settings.

The GPU's synthetic benchmark scores provide context for this ranking. The RX 9070 XT scores 26,795 in PassMark G3D and 15,864 in GPU compute, with a 3DMark Steel Nomad DX12 score of 7,260. Its percentile rank against all GPUs is 55th, and its average benchmark score is 13,543. The nearest rivals in the GPU benchmark database are the AMD Radeon HD 7770M (average score 13,536, delta 0.1%), the NVIDIA GeForce GTX 570 (13,515, delta 0.2%), and the NVIDIA P106-090 (13,470, delta 0.5%). This places the RX 9070 XT's synthetic score in a curious position — it is not in the top tier of GPUs by this metric, yet its real-world performance in Downfall is sufficient to rank in the top quarter of combos.

The CPU's contribution to this rank is also significant. With an 81st percentile rank against all CPUs and an average benchmark score of 29,879, the 5800XT is a solid mid-to-high-range processor. Its nearest rivals include the AMD Ryzen 7 7840H (delta 0%), the AMD Ryzen 7 8845HS (delta -0.3%), and the AMD Ryzen 5 9600X (delta 0.6%). The CPU's strong multi-threaded scores (23,794 in Cinebench R23 multi-core) ensure that the combo does not suffer from CPU bottlenecks in most scenarios, which likely contributes to its favorable ranking in Downfall.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1080p gaming, the Medium preset at 255 FPS offers an excellent balance between visual quality and performance, with a minimum of 217 FPS ensuring smooth gameplay even in demanding scenes. The High preset at 209 FPS is also viable, but the 18% frame rate reduction from Medium may not justify the visual gains for competitive play. Ultra at 1080p drops to 131 FPS, which is still playable but represents a significant performance cost.

At 1440p, the Medium preset at 182 FPS is the recommended choice for high-refresh-rate displays, as it maintains a minimum of 155 FPS. High at 150 FPS is also acceptable for 144 Hz monitors, though the margin above the refresh rate is thinner. Ultra at 1440p (93 FPS) is suitable for 90 Hz displays but may not fully utilize 120 Hz or higher refresh rates. Low at 223 FPS is only recommended if visual fidelity is not a priority, as the frame rate gains over Medium are modest (22.5%) compared to the visual quality loss.

For 4K gaming, the Medium preset at 113 FPS (minimum 96) is the best option, as it stays above 90 FPS and provides a smooth experience on 60-100 Hz displays. High at 93 FPS is also viable for 60 Hz panels, but the 17.7% performance drop from Medium may not be worth the visual improvement. Ultra at 58 FPS is below the 60 FPS threshold, which can lead to perceptible stuttering on standard 60 Hz displays, and Low at 139 FPS sacrifices too much visual quality for the resolution. The data clearly indicates that Medium is the sweet spot for this combo at 4K, balancing the GPU's rendering load with acceptable frame delivery.

GPU Role

The AMD Radeon RX 9070 XT is built on the RDNA 4.0 architecture (Navi 48 chip) using TSMC's 4 nm process, with 53,900 million transistors on a 357 mm² die. The GPU has 4,096 shading units, 256 TMUs, and 128 ROPs, along with 64 ray tracing cores. Its base clock is 1660 MHz, game clock is 2400 MHz, and boost clock reaches 2970 MHz. The memory subsystem consists of 16 GB of GDDR6 on a 256-bit bus, providing 644.6 GB/s of bandwidth at 2518 MHz (20.1 Gbps effective). The card's pixel rate is 380.2 GPixel/s, texture rate is 760.3 GTexel/s, and FP32 performance is 48.66 TFLOPS.

In Downfall, the GPU's role becomes increasingly dominant as resolution and settings increase. The measured FPS at 4K Ultra (58) is clearly GPU-limited, as the CPU's strong performance (evidenced by 312 FPS at 1080p Low) cannot compensate for the rendering workload. The 16 GB VRAM is likely sufficient for this game even at 4K Ultra, as the game's release date of 2016 suggests it does not require excessive memory capacity. The GPU's bandwidth of 644.6 GB/s provides ample data throughput for texture streaming at high resolutions.

The GPU's synthetic benchmark scores show a percentile rank of 55 against all GPUs, with a PassMark G3D score of 26,795. However, the nearest rivals in the benchmark database (AMD Radeon HD 7770M, NVIDIA GeForce GTX 570, NVIDIA P106-090, AMD Radeon Pro 555) all have average scores around 13,400-13,500, which is nearly half the RX 9070 XT's own average score of 13,543 — this discrepancy suggests the synthetic average is skewed by the lower DirectX 10 and 12 scores (154 and 78, respectively) compared to the higher OpenCL (17,428) and Vulkan (65,879) results. The real-world gaming performance, as measured in Downfall, demonstrates that the GPU is capable of delivering 93 FPS at 4K High and 150 FPS at 1440p High, which are strong results for a modern mid-range card. The 4K Ultra result of 58 FPS indicates that the GPU reaches its practical limit at the highest settings, where the combination of pixel count and rendering features overwhelms the 48.66 TFLOPS of compute throughput.
