Lockdown Protocol

The AMD Ryzen 9 9950X3D paired with the AMD Radeon RX 6750 XT presents a compelling study in bottleneck dynamics for Lockdown Protocol, an FPS title where the balance between CPU headroom and GPU throughput dictates the experience. The measured frame rates across resolutions reveal a system where the GPU is the primary scaling factor, while the CPU’s substantial margin of performance ensures it rarely becomes the limiting component.

Resolution Scaling

The data shows a classic GPU-bound scaling pattern as resolution increases. At 1080p with High settings, the combo delivers an average of 122 FPS. Moving to 1440p drops performance to 92.9 FPS, a 23.9% reduction, and at 4K the average falls to 59.4 FPS, a 51.3% reduction from the 1080p figure. This steep decline indicates that the RX 6750 XT’s rendering pipeline is the primary constraint, as the workload per frame grows exponentially with pixel count.

The behavior at Low settings further confirms this. At 1080p Low, the system achieves 202.2 FPS, which is an enormous 65.7% higher than the High preset at the same resolution. However, at 4K Low, the average drops to 95.3 FPS, which is still higher than the 4K High result of 59.4 FPS. This suggests that even when the GPU’s shading load is reduced, the memory bandwidth and fill rate of the card become limiting factors at 4K. The scaling from 1080p Low to 4K Low shows a 52.9% performance loss, nearly identical to the loss seen on the High preset, indicating that the resolution penalty is consistent regardless of settings.

The Ultra preset tells a different story. At 1080p Ultra, the average is 91.5 FPS, which is lower than the 4K Low result of 95.3 FPS. This is a curious inversion: lowering resolution while increasing quality produces a net loss in frame rate. This points to the GPU’s compute units and texture units being saturated by the Ultra preset’s effects, such as advanced shading and post-processing, rather than being limited by pixel output alone. The 1440p Ultra figure of 65.4 FPS and 4K Ultra of 41.6 FPS continue this trend, with the 4K Ultra result being the lowest of any configuration, showing a 54.6% drop from 1080p Ultra.

CPU Role

The Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. Its benchmark scores are exceptional: a Cinebench R23 multi-core score of 59712 and a single-core score of 8430. In Lockdown Protocol, the CPU’s role appears to be providing a high ceiling for frame generation, given that the GPU is the bottleneck. The fact that the system hits 202.2 FPS at 1080p Low indicates that the CPU can feed the GPU far more frames than the GPU can render at higher settings.

The processor’s core configuration and high boost clock of 5.70 GHz are relevant here. The single-thread performance, measured at 1292 in 3DMark single-thread, ensures that the game’s main logic thread is not a constraint. The 128 MB of shared L3 cache is also a factor, as it helps reduce memory latency for frequently accessed data, which can be beneficial in FPS titles with complex scene graphs. The CPU’s percentile ranking of 96 versus all CPUs places it in the top tier of processors, and its average benchmark score of 71660 is only 0.9% higher than the Intel Xeon Platinum 8270, its closest rival. This headroom means that in this combo, the CPU is never the limiting factor, even at 1080p Low where the GPU is working the least.

The multi-threaded capabilities, evidenced by a PassMark multi-thread score of 70255, are more than sufficient for the game’s background tasks. The data suggests that the CPU’s 16 cores and 32 threads are not being fully utilized by Lockdown Protocol, as the frame rate scales almost entirely with GPU load. The CPU’s 3DMark 16-thread score of 16374 versus its 2-thread score of 2549 shows a scaling efficiency of approximately 6.4x, which is typical for a high-core-count part, but the game’s performance does not rely on that scaling.

FAQ

Q: What is the average frame rate at 1440p with High settings?

A: The average frame rate at 2560x1440 with High settings is 92.9 FPS. This is a 23.9% reduction from the 1080p High result, indicating that the GPU is the primary scaling component.

Q: How does the Ultra preset affect performance compared to High?

A: At 1080p, Ultra delivers 91.5 FPS against 122 FPS on High, a 25% penalty. At 4K, the Ultra preset produces 41.6 FPS versus 59.4 FPS on High, showing that the Ultra preset’s additional rendering features disproportionately impact the GPU at higher resolutions.

Q: Is the CPU or GPU the bottleneck in this configuration?

A: The data indicates the GPU is the bottleneck across all tested settings. Evidence includes the 51.3% frame rate drop from 1080p to 4K on High settings, while the CPU’s single-core score of 8430 in Cinebench R23 suggests it has ample headroom for the game’s logic.

Q: What is the best performance-to-quality setting based on the data?

A: The 1440p High preset offers a balanced result at 92.9 FPS. It provides a 56.3% higher frame rate than 4K High (59.4 FPS) while maintaining a higher resolution than 1080p, where High yields 122 FPS but with less pixel density.

Q: How does the GPU’s performance rank relative to other cards?

A: The RX 6750 XT has a percentile ranking of 79 versus all GPUs. Its average benchmark score of 35327 is only 0.2% higher than the AMD Radeon RX 5600M and 1.3% lower than the NVIDIA GeForce RTX 3080, placing it in a mid-to-high tier for rasterization performance.

Q: Does lowering resolution always increase frame rate?

A: Not always. At 1080p Ultra, the average is 91.5 FPS, which is lower than the 4K Low result of 95.3 FPS. This suggests that the Ultra preset’s compute load is more demanding than the pixel fill rate at 4K Low, making the GPU the limiting factor in both cases.

How This Combo Ranks

In the benchmark database, this specific combination of the AMD Ryzen 9 9950X3D and the AMD Radeon RX 6750 XT ranks 849th out of 1637 tested combos for Lockdown Protocol. This places it in the 51.9th percentile of all tested systems. The ranking is heavily influenced by the GPU’s mid-range standing, as the CPU is a top-tier part. The GPU’s percentile of 79 versus all GPUs is lower than the CPU’s percentile of 96, which explains why the combo does not rank higher overall.

The rank of 849 suggests that while the system is capable of producing playable frame rates at 1080p and 1440p, it is outperformed by a majority of combinations that likely feature higher-end graphics cards. The data shows that the CPU’s potential is largely untapped in this pairing, as the frame rates are consistently limited by the GPU. For instance, the 1080p Low result of 202.2 FPS is a clear indicator of CPU capability, but the 4K Ultra result of 41.6 FPS shows that the GPU struggles with the highest loads. The gap between the CPU’s performance ceiling and the GPU’s actual output is the primary reason for the mid-pack ranking.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, manufactured on a 7 nm process. It features 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 432.0 GB/s. This memory configuration is a key factor in the 4K performance, as the bandwidth is sufficient for the higher resolution but becomes taxed when combined with the Ultra preset’s effects. The GPU’s boost clock of 2600 MHz and game clock of 2495 MHz contribute to its compute throughput of 13.31 TFLOPS.

The GPU’s benchmark scores show a mixed profile. Its PassMark G3D score of 20700 is solid, but the DirectX 12 score of 80 is notably lower, which might indicate driver overhead or architectural limitations in certain API paths. The Geekbench Vulkan score of 109310 is significantly higher than the OpenCL score of 107621, suggesting that the card performs better in Vulkan workloads. In Lockdown Protocol, the GPU’s role is to render the scene, and the data shows that its performance is consistent with a mid-range card. The 1080p High result of 122 FPS is good, but the 4K Ultra result of 41.6 FPS highlights the card’s limitations with heavy shading and post-processing at high pixel counts.

The GPU’s nearest rival, the NVIDIA GeForce RTX 3080, has an average score that is 1.3% higher, which is a small margin. This suggests that the RX 6750 XT is competitive with last-generation high-end cards in synthetic benchmarks, but the Lockdown Protocol results indicate that its real-world performance in this title is more constrained. The 1440p Medium result of 102.1 FPS versus the 1440p High result of 92.9 FPS shows that the card scales well with reduced settings, but the jump from Medium to Ultra at 1440p (a 35.9% drop) shows that the Ultra preset is particularly demanding on the GPU’s resources.
