Downfall

The AMD Ryzen 7 5800X and AMD Radeon RX 6700 XT combination delivers a solid 1080p and 1440p experience in Downfall, with 4K proving to be the breaking point for ultra settings. This pairing places the 5800X’s 8-core/16-thread Zen 3 architecture against a 12 GB RDNA 2 GPU, resulting in a balanced system that favors high refresh rates at lower resolutions but requires settings compromises at higher ones. The data indicates the CPU carries more weight at 1080p, while the GPU becomes the limiting factor as resolution increases.

CPU Role

The AMD Ryzen 7 5800X is built on the Zen 3 architecture (Vermeer codename) using a 7 nm process from TSMC, featuring 8 cores and 16 threads. Its base clock is 3.80 GHz with a boost clock of 4.70 GHz, and it draws 105 W TDP from the AMD Socket AM4 platform. The processor includes 64 KB of L1 cache per core, 512 KB of L2 per core, and a shared 32 MB L3 cache, providing strong single-thread and multi-thread performance for a horror title like Downfall.

Benchmark data shows the 5800X achieves a Cinebench R23 multicore score of 15476 and a single-core score of 1574.5, with Geekbench scores of 11036 (multicore) and 2032 (single-core). The 3DMark results further illustrate scalability: 1846 for 2 threads, 3543 for 4 threads, 6035 for 8 threads, and 7586 for 16 threads, indicating that performance scales nearly linearly up to 8 threads before plateauing. This pattern suggests Downfall benefits from the 8-core design, but the game does not heavily utilize all 16 threads, as the max-thread score of 7578 is nearly identical to the 8-thread result.

In Downfall, the CPU’s role is most pronounced at lower resolutions where the GPU is not saturated. At 1080p Low, the combo achieves 229 FPS, which drops to 154 FPS at High settings — a gap that reflects both CPU and GPU workload changes. The 5800X’s PassMark multithread score of 27732 and single-thread score of 3445 indicate it handles the game’s logic, physics, and AI demands without bottlenecking the RX 6700 XT at 1080p, but the data shows the CPU’s influence wanes as resolution climbs.

Comparing to its nearest rivals, the 5800X has an average benchmark score of 29123, placing it 0.1% ahead of the Intel Core Ultra 5 135H (29093) and 0.6% ahead of the AMD Ryzen 5 5600XT (28940). It trails the Intel Xeon Phi 7210 by 0.4% (29245) and the Intel Core i5-13500HX by 0.5% (29270). This tight grouping means the 5800X is competitive but not dominant among its peers, with a percentile rank of 81 among all CPUs — a strong showing for a desktop part, though not top-tier.

GPU Role

The AMD Radeon RX 6700 XT is based on the Navi 22 chip with RDNA 2.0 architecture, fabricated on a 7 nm process with 17,200 million transistors on a 335 mm² die. It features 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth, with memory clocked at 2000 MHz (16 Gbps effective). The GPU’s base clock is 2321 MHz, boost clock is 2581 MHz, and game clock is 2424 MHz, with a TDP of 230 W and requiring a 550 W suggested PSU.

The GPU’s shading units number 2560, with 160 TMUs and 64 ROPs, plus 40 ray tracing cores. Its pixel rate is 165.2 GPixel/s and texture rate is 413.0 GTexel/s, while FP32 performance reaches 13.21 TFLOPS. Benchmark results include a PassMark G3D score of 19786 and a Geekbench Vulkan score of 93500, indicating solid DirectX 12 and Vulkan support (DirectX 12 Ultimate, Vulkan 1.4). The GPU’s percentile rank is 72 among all GPUs, with an average benchmark score of 27425.

In Downfall, the RX 6700 XT’s 12 GB VRAM is sufficient for all tested settings, as frame rates at 4K Ultra (43 FPS) and 1080p Ultra (96 FPS) suggest VRAM is not the constraint — compute and bandwidth are. The GPU’s nearest rival is the NVIDIA GeForce RTX 4070 Mobile, which scores 27435 (0% delta), followed by the RTX 3090 at 27565 (-0.5% delta) and the RTX PRO 4000 Blackwell at 27135 (1.1% delta). This places the RX 6700 XT in the upper mid-range tier, capable of high refresh 1080p and solid 1440p, but struggling at 4K Ultra due to the 13.21 TFLOPS FP32 ceiling.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern from 1080p to 4K. At High settings, the average FPS drops from 154 at 1920x1080 to 110 at 2560x1440 (a 28.6% reduction) and further to 68 at 3840x2160 (a 55.8% reduction from 1080p). This steep decline indicates the GPU becomes the primary bottleneck as pixel count increases, since the CPU’s workload remains relatively constant while the GPU’s fill rate and shading demands grow exponentially.

At Low settings, the scaling is similar: 229 FPS at 1080p, 164 FPS at 1440p (28.4% drop), and 102 FPS at 4K (55.5% drop). The consistency of these percentage drops across settings — roughly 28% from 1080p to 1440p and 55% from 1080p to 4K — strongly suggests the RX 6700 XT is the limiting component at higher resolutions, while the 5800X has ample headroom. If the CPU were the bottleneck, the 1080p-to-1440p drop would be smaller, as the GPU would still have spare capacity.

However, the settings impact at each resolution tells a different story. At 1080p, moving from Low to Ultra drops FPS from 229 to 96 (a 58% reduction), which is a massive hit that indicates the GPU is fully utilized even at 1080p Ultra. At 4K, the same settings change drops FPS from 102 to 43 (a 57.8% reduction), showing that the GPU’s compute limits are consistent regardless of resolution. The data indicates the combo is CPU-bound at 1080p Low and Medium, but GPU-bound at 4K and at Ultra settings across all resolutions.

Measured FPS Breakdown

1920x1080: At Low settings, the combo achieves an average of 229 FPS. Medium settings reduce this to 187 FPS (with min/max of 159/215), High settings yield 154 FPS, and Ultra drops to 96 FPS. The 229 FPS at Low suggests the CPU can push well beyond 200 FPS when the GPU is not stressed, but the 96 FPS at Ultra indicates the RX 6700 XT’s limits are reached even at 1080p when all effects are enabled.

2560x1440: Low settings produce 164 FPS, Medium 134 FPS (min/max 114/154), High 110 FPS, and Ultra 69 FPS. The 1440p results show a similar pattern to 1080p but with roughly 30% lower frame rates across the board, reflecting the increased pixel count. The Ultra setting at 69 FPS is still playable but noticeably lower than the 96 FPS at 1080p Ultra, indicating that 1440p Ultra is the edge of comfortable performance.

3840x2160: Low settings deliver 102 FPS, Medium 83 FPS (min/max 71/96), High 68 FPS, and Ultra 43 FPS. At 4K, even Low settings cannot maintain 144 FPS, and Ultra falls below 60 FPS, making it unsuitable for smooth gameplay. The 43 FPS at Ultra is a 55.2% drop from the 96 FPS at 1080p Ultra, confirming the GPU’s performance scales poorly with resolution increases.

How This Combo Ranks

The AMD Ryzen 7 5800X + AMD Radeon RX 6700 XT combination ranks 1949 out of 3716 tested combos in Downfall, placing it in the 52.4th percentile (top 47.6%). This mid-pack ranking reflects the balance between the 5800X’s strong CPU performance (81st percentile among CPUs) and the RX 6700 XT’s more modest GPU standing (72nd percentile among GPUs). The combo outperforms many lower-tier pairings but lags behind systems with higher-end GPUs like the RTX 3090, which is a nearest rival to the RX 6700 XT.

The rank suggests that while this pairing is competent for 1080p and 1440p gaming, it does not excel at 4K, which is consistent with the measured FPS data. The 5800X’s CPU headroom is evident in the high 1080p Low FPS (229), but the GPU’s limitations cap the overall ranking. Compared to other combos in the database, this setup offers a strong balance of CPU and GPU for the price point, though the fact pack does not include pricing details beyond launch MSRP values.

FAQ

*Q: Is the AMD Ryzen 7 5800X or the AMD Radeon RX 6700 XT the bottleneck in Downfall?*

A: The data indicates the GPU is the bottleneck at higher resolutions and at Ultra settings, while the CPU has headroom. At 1080p Low, the combo hits 229 FPS, but at 4K Ultra it drops to 43 FPS, showing the GPU limits performance as resolution increases.

Q: What is the best resolution and settings for this combo to achieve 60+ FPS?

A: The combo achieves 60+ FPS at 1080p Ultra (96 FPS), 1440p High (110 FPS), and 4K High (68 FPS). However, 4K Ultra (43 FPS) and 1440p Ultra (69 FPS) fall below or near the 60 FPS threshold, so users should avoid Ultra at 4K.
