Downfall

How This Combo Ranks

The AMD Ryzen 7 5800XT paired with the NVIDIA GeForce RTX 5090 lands at rank 102 out of 3,716 tested CPU-GPU combinations in Downfall. That places the combo in the top 2.7 percent of all tested configurations, a strong showing that reflects both the high refresh rate potential of the RTX 5090 and the 5800XT's ability to feed it in this horror title. The rank is largely driven by the GPU's raw throughput, but the CPU does not bottleneck the experience meaningfully at the resolutions tested, as the FPS data shows.

The RTX 5090 sits at the 92nd percentile among all GPUs in the database, with an average benchmark score of 79,842. Its nearest rivals in the overall GPU rankings include the NVIDIA Tesla P100 PCIe 16 GB (avg score 79,605, delta 0.3 percent), the Tesla P100 PCIe 12 GB (79,396, delta 0.6 percent), and the AMD Radeon RX 6850M XT (78,940, delta 1.1 percent). The RTX 5090 trails the AMD Radeon Pro Vega 64X by 1.4 percent (80,959) in that comparison, a marginal gap that does not translate into meaningful FPS differences in Downfall. For the CPU, the Ryzen 7 5800XT sits at the 81st percentile among all CPUs, with an average benchmark score of 29,879. Its nearest rivals include the AMD Ryzen 7 7840H (29,868, delta 0.0 percent), the Ryzen 7 8845HS and Ryzen 7 7840HS (both 29,955, delta -0.3 percent), and the AMD Ryzen 5 9600X (29,713, delta 0.6 percent). The CPU's performance delta from these rivals is within one percent, meaning any FPS differences in Downfall come from the GPU or game engine, not the processor.

GPU Role

The NVIDIA GeForce RTX 5090 is built on the Blackwell 2.0 architecture with the GB202 chip, fabricated on a 5 nm process at TSMC. It packs 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9 million per square millimeter. The GPU's base clock runs at 2017 MHz, boosting to 2407 MHz. Memory consists of 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s of bandwidth with an effective memory clock of 28 Gbps. The shader array includes 21,760 shading units, 680 texture mapping units, 176 ROPs, 170 RT cores, and 680 tensor cores. Pixel rate is 423.6 GPixel/s, texture rate is 1,636.8 GTexel/s, and FP32 compute reaches 104.8 TFLOPS, with FP16 at the same 104.8 TFLOPS (1:1 ratio). The card is dual-slot, requires a single 16-pin power connector, and the suggested PSU is 950 W. Its TDP is 575 W. Display outputs include 1x HDMI 2.1b and 3x DisplayPort 2.1b. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. It uses a PCIe 5.0 x16 interface. Physical dimensions are 304 mm in length, 137 mm in height, and 40 mm in width.

In Downfall, the RTX 5090's 32 GB VRAM is far beyond what the game requires at any resolution or setting tested. The game is from 2016, and even at 4K Ultra, the VRAM usage would not approach the capacity. The 1.79 TB/s memory bandwidth is also overkill for this title, but it ensures that texture streaming and asset loading never become bottlenecks. The high boost clock of 2407 MHz, combined with the massive shader count, directly explains the triple-digit FPS numbers seen across all resolutions except 4K Ultra. The GPU's compute capability, 104.8 TFLOPS FP32, allows the engine to push high frame rates even with the horror game's lighting and particle effects. The RTX 5090's nearest rival in the database, the Tesla P100, is a compute-focused card with different driver optimizations, yet the delta is only 0.3 percent in average benchmark score—Downfall benefits from the RTX 5090's gaming-oriented feature set.

CPU Role

The AMD Ryzen 7 5800XT is a Zen 3 architecture processor, codenamed Vermeer, manufactured on TSMC's 7 nm process. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The CPU's TDP is 105 W, and it uses the AMD Socket AM4. It supports DDR4 memory in dual-channel configuration with 51.2 GB/s bandwidth, and ECC memory is supported. The CPU has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of shared L3 cache. It provides 20 PCIe Gen 4 lanes from the CPU. The 5800XT has no integrated graphics. The transistor count is 4,150 million on a 74 mm² die. It was released on 2024-07-30, with a launch MSRP of $249. The multiplier is unlocked. Part number is 100-000001582.

In Downfall, the CPU's role is to feed the RTX 5090 with draw calls and physics data. The 8-core, 16-thread configuration is more than adequate for a horror game from 2016, which typically uses fewer threads. Benchmark results show the 5800XT's single-thread performance at 3dmark_single_thread score of 959, and Cinebench R23 single-core score of 3,359. Multi-threaded performance is strong with Cinebench R23 multi-core score of 23,794, and 3dmark_max_threads score of 7,680. The CPU's 81st percentile ranking among all CPUs means it outperforms most processors in the database, and its nearest rivals—all Ryzen 7 or Ryzen 5 mobile or desktop parts—show deltas under one percent. In practice, the 5800XT does not limit the RTX 5090 at any resolution tested, as the FPS scaling from 1080p to 4K follows GPU-bound behavior. The CPU's 4.80 GHz boost clock ensures that single-threaded game logic runs without stutter, and the 32 MB L3 cache helps with level streaming in Downfall's environments.

Measured FPS Breakdown

The measured FPS data covers three resolutions—1920x1080, 2560x1440, and 3840x2160—across four settings levels: Low, Medium, High, and Ultra. The data is marked as measured, not simulated.

At 1920x1080, the average FPS ranges from 395 on Low to 190 on Ultra. Medium yields 368 FPS (min 312, max 423), and High yields 303 FPS. The step from Low to Medium is a 6.8 percent drop, from Medium to High is 17.7 percent, and from High to Ultra is 37.3 percent. These are large absolute numbers; even at Ultra, the 190 FPS average is far above any 60 Hz display's refresh rate.

At 2560x1440, the pattern is similar but with lower absolute values. Low produces 323 FPS, Medium 264 FPS (min 225, max 304), High 217 FPS, and Ultra 135 FPS. The drop from Low to Medium is 18.3 percent, Medium to High is 17.8 percent, and High to Ultra is 37.8 percent. The Ultra setting at 1440p still clears 135 FPS, which is sufficient for high-refresh monitors.

At 3840x2160, the numbers compress. Low yields 201 FPS, Medium 164 FPS (min 140, max 189), High 135 FPS, and Ultra 84 FPS. The drop from Low to Medium is 18.4 percent, Medium to High is 17.7 percent, and High to Ultra is 37.8 percent. At 4K Ultra, the average dips below 90 FPS, which is still playable but shows the GPU's limits under maximum settings.

The min FPS data is only available for Medium settings: at 1080p, the min is 312 FPS; at 1440p, 225 FPS; at 4K, 140 FPS. These min values indicate that frame pacing remains consistent, with no severe drops below the average. The max FPS at Medium follows the same trend: 423 at 1080p, 304 at 1440p, and 189 at 4K.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the limiting component. At Low settings, scaling from 1080p to 1440p reduces FPS by 18.2 percent (395 to 323), and from 1440p to 4K by 37.8 percent (323 to 201). At Medium, the reductions are 28.3 percent (368 to 264) and 37.9 percent (264 to 164). At High, 28.4 percent (303 to 217) and 37.8 percent (217 to 135). At Ultra, 28.9 percent (190 to 135) and 37.8 percent (135 to 84).

The near-constant 37.8 percent drop from 1440p to 4K across all settings indicates a GPU-bound scenario. The 4K resolution quadruples the pixel count from 1080p, and the drop from 1080p to 4K is approximately 79 percent at Low (395 to 201), 55 percent at Medium (368 to 164), 55 percent at High (303 to 135), and 56 percent at Ultra (190 to 84). The nonlinear scaling—larger drops at lower settings—suggests that at Low, the CPU may still be contributing some overhead, but at Medium and above, the GPU is fully saturated.

The RTX 5090's 32 GB VRAM and 1.79 TB/s bandwidth ensure that memory is not the bottleneck at 4K. The 4K Ultra result of 84 FPS is the only sub-100 FPS figure in the entire dataset, and it comes from the GPU's compute limits, not from memory or CPU. The scaling pattern is textbook GPU-bound: each settings tier at the same resolution costs roughly the same percentage of performance, regardless of resolution. This means that for users with a 1440p 144 Hz monitor, the combo can handle High settings at 217 FPS with headroom; for 4K 120 Hz displays, Medium at 164 FPS is the safe choice.

Settings Recommendations

Based on the measured FPS rows, the best experience per the data depends on the display's refresh rate. For 1080p, every setting from Low to Ultra delivers over 190 FPS, so the recommendation is to use Ultra for maximum visual quality—the 190 FPS average is still far beyond what most 1080p monitors support (typically 144 Hz or 240 Hz). If a 240 Hz display is in use, High at 303 FPS or Medium at 368 FPS would be better, but the difference between High and Ultra in visual terms may not justify the FPS drop for competitive play.

For 1440p, the sweet spot is High at 217 FPS. This clears 144 Hz and 165 Hz refresh rates with significant margin. Ultra at 135 FPS still exceeds 120 Hz, but the 37.8 percent drop from High to Ultra makes High the better choice for fluid motion; the visual uplift from High to Ultra in a 2016 horror game is unlikely to be worth losing 82 FPS. For 4K, the situation is different. Ultra at 84 FPS is playable on a 60 Hz display, but Medium at 164 FPS is the highest setting that clears 120 Hz. High at 135 FPS also clears 120 Hz, but Medium provides a 21.5 percent FPS improvement over High (164 vs 135) with presumably similar visual impact at 4K. The min FPS data for Medium—140 at 4K, 225 at 1440p, 312 at 1080p—shows that Medium maintains consistent frame times, avoiding the stutter that might occur at Ultra.

In summary, the data suggests: for 1080p, use Ultra (190 FPS). For 1440p, use High (217 FPS). For 4K, use Medium (164 FPS) to balance frame rate and quality. These choices maximize the FPS headroom relative to the visual settings, based on the measured rows.
