Lockdown Protocol

Lockdown Protocol’s benchmark data for the AMD Ryzen 9 5900X and AMD Radeon RX 7900 XT combination shows a system that scales predictably with settings and resolution. The dataset provides twelve measured average FPS points across four presets and three resolutions, offering a clear picture of where this pairing performs best and where its bottlenecks emerge.

Settings Recommendations

The measured rows indicate that the High preset at 2560x1440 delivers the most balanced experience for this combo. At 1440p High, the average FPS is 129.6, which is comfortably above the 83.5 FPS recorded at 4K High but still far from the 273.9 FPS ceiling seen at 1080p Low. The jump from High to Ultra at 1440p is steep—a drop from 129.6 to 96.5 FPS—while the step from Medium to High costs only 16.9 FPS (146.5 to 129.6). This suggests High is the sweet spot, as it retains most of the visual fidelity of Ultra without the disproportionate frame rate penalty.

For users prioritizing maximum smoothness over visuals, 1080p Medium offers an excellent compromise: 202.6 FPS average, which is more than double the 4K High result and only 71.3 FPS below the absolute maximum recorded on this system. The Low preset at 1080p hits 273.9 FPS, but the gap between Low and Medium (71.3 FPS) is much larger than the gap between Medium and High (29.1 FPS), indicating that Medium captures most of the performance headroom while adding meaningful quality.

At 4K, the situation changes. The Ultra preset drops to 60.6 FPS, which is technically playable but leaves little margin for frame time spikes. High at 4K (83.5 FPS) is the more sensible choice for UHD displays, as it stays above the 60 FPS threshold while Medium (92.2 FPS) and Low (135.1 FPS) offer progressively more headroom. The data clearly shows that High at 1440p is the default recommendation, with 1080p Medium as the alternative for high-refresh monitors.

CPU Role

The Ryzen 9 5900X brings 12 cores and 24 threads to this pairing, with a base clock of 3.70 GHz and a boost clock of 4.80 GHz. Its architecture is Zen 3 on the Vermeer codename, built on a 7 nm process at TSMC. The CPU’s benchmark profile shows strong multi-threaded performance: Cinebench R23 multicore scores 33150, while the single-core score is 4680. Geekbench multicore reaches 11877 and single-core 2202. These numbers place the CPU in the 90th percentile against all CPUs, with an average benchmark score of 39453.

In Lockdown Protocol, the CPU’s 12 cores appear sufficient to avoid bottlenecking the GPU at lower resolutions. At 1080p Low, the system produces 273.9 FPS, which is likely limited by the engine’s single-thread performance rather than the CPU’s core count. The 3DMark 16-thread score of 9075 and max-thread score of 10075 indicate that the CPU scales well across its core count, but the game’s demands at 1080p Low (273.9 FPS) suggest that individual core speed matters more than thread count in this scenario. The single-thread 3DMark score of 941 and Cinebench R15 single-core of 471 are modest, yet they are sufficient to drive frame rates well above 200 FPS at 1080p.

How This Combo Ranks

The combination of the Ryzen 9 5900X and RX 7900 XT ranks 322nd out of 1637 tested combos in Lockdown Protocol. This places it in the top 20% of all pairings in the database. The rank reflects a system that is decidedly above average but not at the absolute top tier, which is consistent with the CPU’s 90th percentile standing and the GPU’s 82nd percentile standing. The CPU’s nearest rivals—AMD EPYC 4245P (0.2% higher average score), Ryzen 7 PRO 8845HS (0.7% lower), Intel Core i7-13700F (0.9% higher), and Core i7-13700 (1% lower)—show that the 5900X sits in a tightly contested performance band. Similarly, the GPU’s nearest rivals include the RTX 5080 Mobile (0% delta), CMP 70HX (0.3% higher), MX570 (0.4% lower), and RTX 4080 Mobile (0.6% higher), indicating the 7900 XT is closely matched with those parts in synthetic benchmarks.

The combo rank of 322/1637 suggests that while individual components are strong, the pairing does not unlock the absolute maximum potential in this game. The measured FPS data shows this is not a weakness of either component but rather the game’s scaling behavior. The system achieves 273.9 FPS at 1080p Low, which is excellent, but the rank implies other combos in the database achieve higher maximums, likely through more balanced CPU-GPU pairings at higher resolutions.

Resolution Scaling

The FPS progression from 1080p to 4K reveals where the bottleneck shifts. At 1080p High, the system produces 171.5 FPS. Moving to 1440p High drops this to 129.6 FPS (a 24.4% reduction), and 4K High yields 83.5 FPS (a 35.6% reduction from 1440p). The scaling is not linear—the 4K to 1440p drop is steeper than the 1440p to 1080p drop, which indicates that the GPU becomes increasingly dominant as resolution rises.

At 1080p Low (273.9 FPS), the CPU is clearly the limiting factor, as the GPU has ample headroom. The jump to 1440p Low (207.4 FPS) is a 24.3% reduction, and 4K Low (135.1 FPS) is a 34.9% reduction from 1440p. The pattern holds across presets: the percentage drop from 1080p to 1440p is consistently around 24-29%, while the drop from 1440p to 4K is consistently around 34-37%. This consistent scaling pattern suggests that the GPU’s fill rate and memory bandwidth become the primary constraint at higher resolutions, while the CPU maintains adequate frame delivery even at 4K.

The 4K Ultra result of 60.6 FPS is the lowest measured value, and it is 55.4% below the 1080p Ultra result of 132.1 FPS. This large drop at Ultra settings across resolutions indicates that the game’s highest preset places significant stress on the GPU’s compute units, particularly at 4K where the pixel count quadruples from 1080p.

GPU Role

The Radeon RX 7900 XT is built on the Navi 31 chip with RDNA 3.0 architecture, featuring 5376 shading units, 336 TMUs, and 192 ROPs. It has 84 RT cores and a boost clock of 2394 MHz with a game clock of 2025 MHz. The memory subsystem includes 20 GB of GDDR6 on a 320-bit bus, delivering 800.0 GB/s of bandwidth. The GPU’s compute performance is substantial: FP32 reaches 51.48 TFLOPS, and the pixel rate is 459.6 GPixel/s with a texture rate of 804.4 GTexel/s.

In Lockdown Protocol, the GPU’s role becomes evident in the settings scaling. At 1440p, moving from Low (207.4 FPS) to Medium (146.5 FPS) is a 29.4% reduction, while Medium to High (129.6 FPS) is an 11.5% reduction, and High to Ultra (96.5 FPS) is a 25.5% reduction. The GPU’s bandwidth and shading capacity drive these differences. At 4K, the same pattern holds but with more severe drops: Low (135.1 FPS) to Medium (92.2 FPS) is 31.8% lower, Medium to High (83.5 FPS) is 9.4% lower, and High to Ultra (60.6 FPS) is 27.4% lower. The 20 GB VRAM is ample for this game at any resolution, as no measured row suggests memory capacity limits.

The GPU’s percentile rank of 82 and average benchmark score of 38358 position it below the CPU’s 90th percentile, which aligns with the observed resolution scaling where the GPU becomes the limiting factor at 4K. The 3DMark Steel Nomad DX12 score of 5623 and PassMark G3D score of 29009 reflect strong raw performance, but the game’s optimization appears to favor the CPU’s capabilities at lower resolutions.

FAQ
