Lockdown Protocol

The AMD Ryzen 5 5600 and AMD Radeon RX 6750 XT pairing delivers a solid 1080p and 1440p experience in Lockdown Protocol, but 4K Ultra demands compromises. The measured frame rates show a clear pattern: this combo is built for high-refresh gaming at mainstream resolutions, not for maxing out pixel counts.

Resolution Scaling

The frame rate curve from 1080p to 4K reveals where this combo’s bottleneck shifts. At 1080p Low, the system produces 201.3 FPS, which drops to 145.8 FPS at 1440p Low (a 27.6% reduction) and then to 92.3 FPS at 4K Low (a 36.7% further drop). This scaling pattern indicates that at lower resolutions, the CPU is keeping pace, and the GPU is the primary limiter even at Low settings.

The gap between Low and Ultra settings widens dramatically as resolution increases. At 1080p, the spread from Low to Ultra is 106.8 FPS (201.3 down to 94.5). At 1440p, that spread narrows to 78.5 FPS (145.8 down to 67.3). At 4K, the spread compresses further to 50.9 FPS (92.3 down to 41.4). This compression suggests that at 4K, the GPU is so heavily loaded that even dropping to Low settings cannot fully relieve the pressure—the pixel throughput demand dominates.

The 4K High result of 59.1 FPS is notable because it sits just under the 60 FPS threshold, while 4K Medium hits 64.9 FPS. The jump from 4K Ultra (41.4 FPS) to 4K High (59.1 FPS) represents a 42.8% improvement, showing that stepping down one notch from Ultra provides substantial headroom. For 4K gaming, the data suggests Medium or High settings are the practical ceiling; Ultra is only viable if you accept sub-45 FPS gameplay.

GPU Role

The RX 6750 XT’s specifications align with the measured results. With 12 GB of GDDR6 memory on a 192-bit bus delivering 432.0 GB/s of bandwidth, the card has ample memory capacity for Lockdown Protocol at any of the tested settings. The 40 RT cores and 64 ROPs contribute to the card’s 166.4 GPixel/s pixel rate, which explains why 4K Ultra (41.4 FPS) falls so far behind 1080p Ultra (94.5 FPS)—the pixel fill requirements at 3840x2160 are roughly four times those at 1920x1080.

The clock behavior matters here. The card’s boost clock of 2600 MHz and game clock of 2495 MHz represent the sustained performance envelope. The 13.31 TFLOPS FP32 throughput places this GPU in a capable mid-range tier, and the benchmark results confirm this: the card’s PassMark G3D score of 20700 and 3DMark Steel Nomad DX12 score of 2548 are consistent with its positioning.

Comparing against nearest rivals, the RX 6750 XT’s average benchmark score of 35327 sits within 1.3% of the NVIDIA GeForce RTX 3080 (35787), but that delta is misleading for gaming—the RTX 3080’s rasterization strength typically exceeds this AMD card in raw FPS. The card is 0.3% ahead of the NVIDIA GeForce RTX 5070 Ti Mobile (35435) and 0.9% ahead of the AMD Radeon 880M (35646), though those are different market segments entirely. The real takeaway: the RX 6750 XT is a 1080p/1440p-focused card, and the 4K results here confirm that its 12 GB frame buffer and 432.0 GB/s bandwidth are sufficient for capacity but not for maxing out 4K settings.

CPU Role

The Ryzen 5 5600’s 6 cores and 12 threads at a 3.50 GHz base and 4.40 GHz boost clock provide the foundation for these results. The CPU’s Cinebench R23 multi-core score of 18309 and single-core score of 2584 indicate solid all-around performance. In Lockdown Protocol, an FPS title, the single-threaded performance often dictates minimum frame pacing, and the 3DMark single-thread score of 882 suggests the CPU can feed the GPU adequately at 1080p.

The evidence for CPU headroom comes from the 1080p Low result of 201.3 FPS. That number is high enough to indicate the CPU is not the limiting factor at that setting—if it were, we would see a plateau regardless of resolution. The 1080p Ultra result of 94.5 FPS versus 4K Low of 92.3 FPS is telling: at 1080p Ultra, the GPU is working harder on effects, while at 4K Low, it is working harder on pixel count. The similarity in FPS suggests the GPU is the consistent bottleneck.

The CPU’s 32 MB of shared L3 cache and dual-channel DDR4 memory support (51.2 GB/s bandwidth) are adequate for this workload. The 4,150 million transistors on a 74 mm² die (7 nm TSMC) give it a 79th percentile ranking among all CPUs, and its nearest rival, the Intel Core i7-11700F, scores 21957 versus the 5600’s 21765—a 0.9% gap that is negligible in gaming. The CPU is not the star here, but it also is not holding back the GPU at 1440p or below.

How This Combo Ranks

In the database of tested combos for Lockdown Protocol, this pairing ranks 851 out of 1637 total combinations. That places it in the 48th percentile of all tested combos—essentially dead center. This is a moderate ranking, not a top-tier result. The interpretation: this combo delivers expected performance for its component tier, but it does not overachieve.

The rank reflects the balance of CPU and GPU. The Ryzen 5 5600’s 79th percentile CPU score and the RX 6750 XT’s 79th percentile GPU score would suggest a higher combo rank, but the game’s specific demands likely favor other architectures. The measured data shows the combo hitting 123.6 FPS at 1080p High and 93.3 FPS at 1440p High, which are playable numbers but not chart-topping. The 4K Ultra result of 41.4 FPS drags the overall ranking down, as 4K performance is a significant weight in the combo ranking methodology.

A: It ranks 851 out of 1637 combos, placing it in the middle of the database. This is a mid-pack result, consistent with its component tier.

Q: What settings should I use for 1440p gaming?

A: For high refresh rates, 1440p Low delivers 145.8 FPS. For better visuals, 1440p High still provides 93.3 FPS, and 1440p Medium hits 102.7 FPS. 1440p Ultra drops to 67.3 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 201.3 FPS, Medium hits 142.1 FPS, High reaches 123.6 FPS, and Ultra falls to 94.5 FPS. The delta between Low and Ultra is 106.8 FPS, showing that settings have a massive impact at this resolution. Even at Ultra, the frame rate is well above 60 FPS, making this resolution comfortable for any settings choice.

At 2560x1440, the performance remains strong but tightens. Low produces 145.8 FPS, Medium hits 102.7 FPS, High reaches 93.3 FPS, and Ultra drops to 67.3 FPS. The spread here is 78.5 FPS. The Ultra result is still above 60 FPS, meaning 1440p Ultra is viable for smooth gameplay, though just barely.

At 3840x2160, the performance becomes more constrained. Low produces 92.3 FPS, Medium hits 64.9 FPS, High reaches 59.1 FPS, and Ultra falls to 41.4 FPS. The spread here is 50.9 FPS. Only Low and Medium settings stay above 60 FPS, and High sits just below that threshold. For 4K, the data recommends Medium settings as the balanced choice, with Low providing a comfortable margin for high-refresh 4K monitors.
