Downfall

The AMD Ryzen 9 5900X paired with the AMD Radeon RX 7700 XT is a desktop combination built around a 12-core Zen 3 processor and a 12 GB RDNA 3 graphics card. In the 2016 horror game Downfall, this pairing produces a wide spread of frame rates depending on resolution and quality preset, ranging from a demanding 49 FPS at 4K Ultra to a fluid 263 FPS at 1080p Low. The data shows a system that can handle high-refresh 1080p and 1440p gaming comfortably, while 4K Ultra remains a challenge that requires settings adjustments.

How This Combo Ranks

Within the benchmark database’s tested combinations for Downfall, this specific CPU-GPU pairing lands at rank 1392 out of 3716 total combos. That places it in the upper third of all tested systems, indicating a solidly above-average configuration for this title. The rank reflects the combined capability of the Ryzen 9 5900X and RX 7700 XT when running this particular horror game, not a universal performance index.

The CPU itself sits in the 87th percentile when compared against all processors in the database, meaning it outperforms roughly 87% of all tested CPUs in general benchmark workloads. Its average benchmark score of 41376 places it in a tight cluster with several recent mobile and desktop chips. The nearest rival, the Intel Core Ultra 7 366H, scores 41263, a delta of just 0.3% — essentially a statistical tie. The Intel Core Ultra 7 356H and AMD Ryzen AI 5 PRO 440 also sit within 0.4% of the 5900X’s average score. On the other side, the Intel Core i7-14650HX trails by 0.5% with a score of 41576, meaning the 5900X actually leads that chip by a small margin in this aggregate metric. These tiny deltas show that, in synthetic CPU benchmarks, the 5900X remains competitive with much newer processors despite its 2020 release date.

The GPU’s percentile ranking is lower, at 67th among all graphics cards, with an average benchmark score of 22549. Its nearest rivals include the NVIDIA GeForce RTX 5060 Mobile, which scores 22435 (0.5% behind the RX 7700 XT), and the RTX 4060 Mobile at 22729 (0.8% ahead). The RTX 2080 leads by 1.5% with a score of 22895, while the older AMD Radeon RX 5700 trails by 1.7% at 22170. These margins are narrow, suggesting the RX 7700 XT occupies a performance tier similar to these cards in synthetic tests, though its real-world Downfall results are what matter most for this analysis.

The combo rank of 1392 out of 3716 means that roughly 62% of tested systems outperform this pairing in Downfall, while 38% fall below it. That may sound modest, but given the game’s age and the fact that many tested combos include newer flagship GPUs, the 5900X + RX 7700 XT still delivers playable performance across most settings, as the measured FPS data will show.

GPU Role

The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5 nm process at TSMC. It packs 28,100 million transistors on a 346 mm² die, giving it a transistor density of 81.2 million per square millimeter. The GPU contains 3,456 shading units, 216 texture mapping units, and 96 raster output units, along with 54 ray tracing cores. Its compute capabilities are rated at 35.17 TFLOPS for both FP32 and FP16 (1:1 ratio), which drives the pixel rate of 244.2 GPixel/s and texture rate of 549.5 GTexel/s.

Memory is a 12 GB pool of GDDR6 on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The memory clock is rated at 2250 MHz, which translates to 18 Gbps effective. For a 2016 horror game like Downfall, 12 GB is more than sufficient — even at 4K with Ultra settings, the game’s texture demands are unlikely to exceed this capacity, though the frame rate data suggests other bottlenecks emerge at that extreme preset.

Clock speeds see a base of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz. The difference between game and boost clocks indicates thermal and power headroom, but the measured FPS in Downfall reflects the sustained performance under load. The card’s TDP is rated at 245 W, requiring a 550 W suggested PSU and two 8-pin power connectors. Its dual-slot design spans 267 mm in length, 135 mm in height, and 50 mm in width, with display outputs including 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C.

In synthetic benchmarks, the RX 7700 XT scores 3316 in 3DMark Steel Nomad DX12, 138383 in Geekbench OpenCL, and 46443 in Geekbench Vulkan. Passmark results show 22547 in G3D and 12912 in GPU compute. These numbers place the card in the 67th percentile overall. Its nearest rival, the RTX 5060 Mobile, is only 0.5% behind, while the RTX 4060 Mobile is 0.8% ahead — a tight grouping that suggests the RX 7700 XT competes directly with those mobile parts in raw compute, though desktop power limits may shift real-game results.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, codenamed Vermeer, and built on TSMC’s 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a TDP of 105 W. The chip uses the AMD Socket AM4 platform with PCIe Gen 4 support. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 64 MB L3 cache — the latter being shared across all cores via Zen 3’s unified design. Memory support is DDR4 with dual-channel access, providing a bandwidth of 51.2 GB/s, and ECC memory is supported.

The 5900X was released on November 4, 2020, with a launch MSRP of $549. It contains 8,300 million transistors across a dual-chiplet design with a total die size of 2x 74 mm². The multiplier is unlocked, making it a viable choice for overclocking, though the benchmark data here reflects stock performance.

Synthetic CPU benchmarks show a strong multi-threaded showing: Cinebench R23 multicore scores 16262, while single-core reaches 1527. Geekbench multicore hits 14118 with single-core at 2083. 3DMark tests reveal scaling from 1852 in 2-thread to 10075 in max-threads, with 16-thread at 9075. Passmark results include a multithread score of 39002, single-thread of 3469, integer math at 140851, floating point math at 77700, and data encryption at 31106. The average benchmark score of 41376 places the 5900X in the 87th percentile of all CPUs, with nearest rivals within 0.5% as noted earlier.

For Downfall, a game released in 2016, the 5900X’s 12 cores and 24 threads are far beyond what the title likely utilizes. The game’s engine probably scales to only a handful of threads, meaning the CPU’s single-thread performance (3dmark_single_thread score of 941, Passmark single-thread of 3469) becomes more relevant than its massive multi-core throughput. The boost clock of 4.80 GHz ensures that the game’s primary thread has ample headroom, which is crucial for maintaining high frame rates at lower resolutions where CPU overhead can become a limiting factor. At 1080p Low, the measured 263 FPS suggests the CPU is keeping up with the GPU’s output, though the frame rate ceiling at that preset is likely more GPU-bound than CPU-bound given the RX 7700 XT’s capabilities.

Measured FPS Breakdown

The measured FPS data covers four resolutions (3840x2160, 2560x1440, 1920x1080) and four quality presets (Low, Medium, High, Ultra), with average FPS recorded for all, plus minimum and maximum FPS for Medium settings only.

At 1080p, the RX 7700 XT and 5900X combination delivers its highest frame rates. Low settings produce an average of 263 FPS. Medium settings drop to 215 FPS on average, with a minimum of 183 FPS and maximum of 247 FPS — the min-to-max spread of 64 FPS indicates some scene-to-scene variance but nothing that would cause stutter on a 144 Hz display. High settings average 176 FPS. Ultra settings still manage 110 FPS on average, which is playable on a high-refresh monitor but noticeably lower than the other presets.

At 1440p, the pattern continues with lower but still strong numbers. Low settings average 188 FPS. Medium averages 154 FPS, with a range of 131 to 177 FPS (a 46 FPS spread, tighter than at 1080p Medium). High settings average 126 FPS. Ultra drops to 79 FPS on average, which is above the 60 FPS threshold for smooth play but below what many gamers would want for fast-paced action — though Downfall is a horror title, not a competitive shooter, so 79 FPS may be acceptable.

At 4K (3840x2160), the GPU begins to strain. Low settings average 117 FPS, which is still respectable. Medium averages 96 FPS, with a minimum of 81 FPS and maximum of 110 FPS — the 29 FPS spread is the smallest of any Medium preset, indicating consistent performance. High settings average 78 FPS. Ultra settings plunge to 49 FPS on average, which is below the 60 FPS standard for smooth gameplay and suggests that Ultra at 4K is not a realistic option for this combo without significant settings tweaks or upscaling.

The Medium preset’s min-max data across resolutions reveals how the game scales: at 1080p Medium, the 183-247 FPS range shows the GPU has headroom; at 1440p Medium, 131-177 FPS shows a proportional drop; at 4K Medium, 81-110 FPS shows the GPU nearing its limit. The lack of min/max data for Low, High, and Ultra presets means only average FPS can be analyzed for those settings, but the averages alone tell a clear story of diminishing returns as resolution increases.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and reveals the limiting component in this system. At Low settings, average FPS goes from 263 at 1080p to 188 at 1440p (a 28.5% drop) and then to 117 at 4K (a 37.8% drop from 1440p, or 55.5% from 1080p). This scaling pattern is characteristic of a GPU-bound scenario — as pixel count increases, the GPU’s fill rate and bandwidth become the bottleneck, while the CPU’s frame generation capacity remains underutilized.

At Medium settings, the averages are 215 at 1080p, 154 at 1440p (a 28.4% drop), and 96 at 4K (a 37.7% drop from 1440p, or 55.3% from 1080p). The percentage drops are nearly identical to Low settings, reinforcing that the GPU is the primary limiter regardless of quality preset. The RX 7700 XT’s 432.0 GB/s memory bandwidth and 244.2 GPixel/s pixel rate are being taxed more heavily as resolution climbs, and the consistent ~55% reduction from 1080p to 4K across presets suggests a purely pixel-driven workload.

At High settings, the pattern holds: 176 at 1080p, 126 at 1440p (a 28.4% drop), and 78 at 4K (a 38.1% drop from 1440p, or 55.7% from 1080p). At Ultra settings, 110 at 1080p, 79 at 1440p (a 28.2% drop), and 49 at 4K (a 38.0% drop from 1440p, or 55.5% from 1080p). The uniformity of these percentage drops — all within a fraction of a point of 28% for 1080p-to-1440p and 38% for 1440p-to-4K — indicates that Downfall scales almost perfectly with resolution, with no sudden cliff or plateau that would suggest a CPU bottleneck at any particular resolution.

The fact that 1080p Low hits 263 FPS while 4K Ultra drops to 49 FPS means the combo is capable of a 5.4x range in performance depending on settings. The limiting component at 4K Ultra is clearly the GPU — the 5900X’s 12 cores are not the constraint when the RX 7700 XT is already producing 49 FPS at 4K Ultra, since the same CPU drives 110 FPS at 1080p Ultra. Conversely, at 1080p Low, the 263 FPS ceiling is likely close to the CPU’s frame rate limit for this game, as the GPU has less work to do per frame. However, without separate CPU and GPU utilization data, the exact crossover point cannot be determined from the FACT PACK alone.
