Lockdown Protocol

The AMD Ryzen 5 5600 and AMD Radeon RX 580 pairing in Lockdown Protocol presents a classic study in balance, where the GPU's age becomes the primary constraint at higher resolutions, while the CPU's modern architecture still provides adequate headroom. The measured frame rates across the three primary resolutions and four quality presets reveal a system that is strictly bound by the graphics card's Polaris 20 silicon, particularly as pixel count rises.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 with this combo shows a steep performance curve that is almost entirely dictated by the GPU. At 1080p High settings, the average frame rate is 50.4 FPS, which drops to 39.5 FPS at 1440p and further down to 24.5 FPS at 4K. This represents a 51% reduction in average frame rate from 1080p to 4K, a scaling pattern typical of a GPU that is running out of fillrate and memory bandwidth as resolution increases.

The RX 580's 256.0 GB/s memory bandwidth and 42.88 GPixel/s pixel rate are the likely limiting factors here. When moving from 1080p to 1440p, the frame rate drops by roughly 22% at High settings, but the 1440p to 4K transition is far more punishing, with a 38% additional performance loss. This non-linear scaling suggests that the GPU's 8 GB of GDDR5 memory and its 256-bit bus are being saturated at 4K, where the pixel throughput demands exceed what the Polaris architecture can deliver.

Interestingly, the CPU's role in this scaling is minimal. The Ryzen 5 5600, with its 6 cores and 12 threads, maintains a 3.50 GHz base clock and 4.40 GHz boost clock, which is sufficient to feed the GPU at lower resolutions but becomes irrelevant once the GPU is the bottleneck. The data shows that at 1080p Low settings, the combo achieves 84.7 FPS, indicating that the CPU can push well beyond 60 FPS when the GPU workload is light. However, at 4K Ultra, the frame rate collapses to 21.6 FPS, a clear sign that the GPU is completely overwhelmed regardless of CPU capability.

FAQ

*Q: What is the best resolution for this combo to maintain 60 FPS in Lockdown Protocol?*

A: The only configuration that achieves an average above 60 FPS is 1920x1080 with Low settings, producing 84.7 FPS. At 1440p Low, the average drops to 59.8 FPS, just below the 60 FPS threshold, while all other settings and resolutions fall short of this mark.

Q: How does the RX 580 compare to its nearest rivals in terms of overall GPU performance?

A: The RX 580's average benchmark score of 13559 puts it essentially level with the NVIDIA GeForce GTX 570 (13564, a 0% delta) and the GTX 950 (13549, a 0.1% delta). It is 1.1% ahead of the AMD Radeon Pro 455 and 1.1% behind the NVIDIA P106-090.

Q: Is the Ryzen 5 5600 a strong performer relative to other CPUs?

A: The CPU sits in the 79th percentile against all CPUs, with an average benchmark score of 21765. Its nearest rival, the Intel Core i7-11700F, scores 21957, which is 0.9% higher, while the AMD EPYC 9554P scores 21899, a 0.6% higher result.

Q: Does the CPU bottleneck the GPU in this game at any resolution?

A: Benchmark results indicate that the CPU is not the limiting factor in most cases. At 1080p Low, the combo reaches 84.7 FPS, suggesting the CPU can sustain high frame rates. However, the GPU becomes the bottleneck as resolution increases, with 4K Ultra yielding only 21.6 FPS, a result that no CPU upgrade could meaningfully improve without a GPU change.

Q: How does the 1080p Ultra performance compare to 1080p High?

A: At 1080p, moving from High to Ultra settings causes a significant frame rate drop from 50.4 FPS to 38.2 FPS, a 24% reduction. This indicates that Ultra settings impose a heavy load on the RX 580's shading units and texture mapping units.

Q: What is the combo's overall ranking among tested configurations?

A: The Ryzen 5 5600 and RX 580 combo ranks 1524 out of 1637 tested combos in Lockdown Protocol, placing it in the lower tier of configurations for this specific game.

CPU Role

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates on the AMD Socket AM4 platform with a 65 W TDP, and its boost clock of 4.40 GHz provides solid single-thread performance for FPS games. In Lockdown Protocol, the CPU's role appears to be secondary to the GPU, as the measured frame rates show that the processor can comfortably handle the game's logic and physics at 1080p.

The CPU's benchmark results support this assessment. Its Cinebench R23 multicore score of 18309 and single-core score of 2584 indicate a balanced processor that can handle both multi-threaded workloads and the single-thread-dominant tasks typical of FPS titles. The 3DMark single-thread score of 882 and 2-thread score of 1737 further suggest that the processor has adequate per-core performance for gaming.

However, the data also shows that the CPU's potential is underutilized in this pairing. At 1080p Low, where the GPU has less work, the combo achieves 84.7 FPS, but this is still below the CPU's theoretical maximum, as indicated by its Passmark multithread score of 21541. The GPU's 6.175 TFLOPS of FP32 performance and 193.0 GTexel/s texture rate are the limiting factors, not the CPU's 51.2 GB/s memory bandwidth or its 32 MB of shared L3 cache.

The Ryzen 5 5600's 4,150 million transistors on a 74 mm² die, manufactured on TSMC's 7 nm process, provide a modern foundation. Yet, in Lockdown Protocol, the CPU's 79th percentile ranking against all CPUs does not translate into high frame rates at higher resolutions, because the RX 580's GCN 4.0 architecture, with its 2304 shading units and 32 ROPs, simply cannot keep pace with the render demands beyond 1080p.

Measured FPS Breakdown

At 1920x1080, the combo demonstrates its best performance. Low settings yield an average of 84.7 FPS, which is the only result that comfortably exceeds 60 FPS. Medium settings produce 64.1 FPS, still playable, while High settings drop to 50.4 FPS. Ultra settings are the most demanding, with an average of 38.2 FPS, a 55% reduction from Low. This spread indicates that the RX 580's 8 GB of GDDR5 memory and 256-bit bus are sufficient at 1080p, but the GPU's compute units struggle with the higher shader complexity of Ultra presets.

At 2560x1440, performance becomes marginal. Low settings average 59.8 FPS, just below the 60 FPS target, while Medium drops to 44.5 FPS and High to 39.5 FPS. Ultra settings yield only 30.9 FPS, which is below the threshold for smooth gameplay. The drop from 1080p High (50.4 FPS) to 1440p High (39.5 FPS) represents a 22% decrease, showing that the GPU's pixel throughput is becoming a constraint.

At 3840x2160, the combo is clearly out of its depth. Low settings average 41.5 FPS, Medium drops to 28.2 FPS, High to 24.5 FPS, and Ultra to just 21.6 FPS. The gap between Low and Ultra at 4K is 48%, which is smaller than at 1080p (55%), suggesting that the GPU is bottlenecked by memory bandwidth across all settings at this resolution. The 4K results are all below 30 FPS except for Low, making this resolution practical only with the lowest quality presets.

How This Combo Ranks

The Ryzen 5 5600 and RX 580 combination ranks 1524 out of 1637 tested combos in Lockdown Protocol, placing it in the 7th percentile of all configurations. This low ranking is primarily due to the GPU's age, as the RX 580's 53rd percentile standing among all GPUs is dragged down by the game's modern rendering requirements. The CPU's 79th percentile ranking does little to compensate for the GPU's limitations.

Compared to the CPU's nearest rivals, the Ryzen 5 5600 holds its own. It is 0.6% behind the Intel Xeon D-1746TER (21635 vs 21765) and 0.6% ahead of the AMD EPYC 9554P. However, these comparisons are for CPU-only benchmarks and do not reflect gaming performance in Lockdown Protocol. The combo's rank suggests that in this specific game, the GPU is the determining factor, and the CPU's relative strength cannot overcome the RX 580's deficiencies.

The RX 580's nearest rivals all have similar average benchmark scores, with the GTX 570 and GTX 950 essentially tied with it. This indicates that the GPU is performing as expected for its class, but that class is simply not sufficient for Lockdown Protocol at higher settings. The combo's rank of 1524 out of 1637 suggests that most other tested configurations, even those with older CPUs, outperform this pairing due to having more capable GPUs. The data makes it clear that in Lockdown Protocol, the RX 580 is the weak link, and any upgrade path should focus on replacing the GPU rather than the CPU.
