Lockdown Protocol

Lockdown Protocol places a wide performance gap between its presets, and the measured FPS data shows a system that scales predictably with resolution. At 1920x1080, the Ryzen 5 7500X3D and RX 6750 XT combo delivers 200 FPS on Low, but that drops to 93 FPS on Ultra—a 107 FPS swing that highlights how much headroom the CPU has at lower settings. Moving to 2560x1440, the spread narrows slightly: 147 FPS on Low versus 68 FPS on Ultra. At 3840x2160, the gap compresses further, with 95 FPS on Low and 44 FPS on Ultra. The pattern is clear: as resolution climbs, the GPU becomes the limiting factor, and the CPU’s advantage at 1080p fades into background noise.

The 4K numbers tell the most instructive story. At 3840x2160, Low settings produce 95 FPS, while High drops to 59 FPS and Ultra falls to 44 FPS. That 51 FPS difference between Low and Ultra at 4K is smaller than the 107 FPS difference at 1080p, which indicates the RX 6750 XT is saturated by pixel throughput rather than shader complexity at higher resolutions. The Medium preset at 4K shows 67 FPS with a minimum of 57 FPS and maximum of 77 FPS, which is the only 4K row with full min/max data. This suggests Medium is the most stable operating point at 4K, though it still sits below the 60 FPS threshold that many players target. The data implies that at 4K, the GPU’s 12 GB VRAM and 432.0 GB/s bandwidth are doing the heavy lifting, and the CPU’s 6 cores and 96 MB L3 cache are largely irrelevant to the outcome.

Resolution Scaling

The FPS drops from 1080p to 4K are steep and consistent across presets. At Low settings, 1080p yields 200 FPS, 1440p yields 147 FPS, and 4K yields 95 FPS—a 52.5% reduction from 1080p to 4K. On High settings, the numbers are 124 FPS, 91 FPS, and 59 FPS respectively, which represents a 52.4% drop. Ultra settings show 93 FPS, 68 FPS, and 44 FPS, a 52.7% decline. The consistency of these percentage drops across presets suggests the scaling is primarily resolution-bound rather than settings-bound. The RX 6750 XT’s pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s are fixed, so increasing pixel count from 2.07 million (1080p) to 8.29 million (4K) quadruples the fill rate demand. The data shows the card handles this with linear degradation, which is typical for a GPU with 64 ROPs and 160 TMUs.

What is more telling is the delta between Low and Ultra at each resolution. At 1080p, the gap is 107 FPS (200 vs 93). At 1440p, it narrows to 79 FPS (147 vs 68). At 4K, it shrinks to 51 FPS (95 vs 44). This compression indicates that at higher resolutions, the GPU’s compute resources—its 2560 shading units and 40 ray accelerators—are fully engaged even on Low settings, leaving less headroom for Ultra effects. The CPU, with a boost clock of 4.50 GHz and 12 threads, is never the bottleneck at 4K because the GPU cannot push enough frames to stress it. At 1080p, however, the CPU’s single-thread score of 3494 and multithread score of 25047 on PassMark suggest it can feed the GPU efficiently, allowing Low settings to reach 200 FPS without stalling. The benchmark results indicate that this combo is a 1080p high-refresh machine first, a 1440p solid performer second, and a 4K compromise third.

FAQ

Q: What is the best resolution for this CPU/GPU combo in Lockdown Protocol?

A: The data shows 2560x1440 on Medium provides 104 FPS average with a minimum of 89 FPS, which is the highest resolution with a stable minimum above 60 FPS. At 1080p, Ultra hits 93 FPS, but the 1440p Medium row offers a better balance of image quality and frame pacing.

Q: How does the CPU compare to its nearest rivals in synthetic benchmarks?

A: The Ryzen 5 7500X3D scores 44573 on average, which is 0.2% ahead of the Intel Core Ultra X9 388H, 0.5% ahead of the Intel Core i9-13950HX, and 0.6% ahead of the AMD Ryzen AI Max 385. It trails the Intel Core i5-14600 by 0.7%. These are marginal differences, so in-game performance will be nearly identical across these chips.

Q: Does the RX 6750 XT have enough VRAM for 4K in this game?

A: The card has 12 GB of GDDR6 memory with a 192-bit bus and 432.0 GB/s bandwidth. At 4K Ultra, the average FPS is 44, and at 4K High it is 59. The VRAM capacity is not explicitly tested, but the performance drop from High to Ultra (15 FPS) suggests memory bandwidth or capacity is a limiting factor at that extreme setting.

Q: What is the FPS difference between Low and Ultra at 1080p?

A: At 1920x1080, Low settings produce 200 FPS, while Ultra produces 93 FPS—a difference of 107 FPS. This is the largest preset gap across all resolutions, indicating that the CPU has significant headroom at 1080p that the GPU can utilize when settings are reduced.

Q: Is the CPU or GPU the bottleneck at 4K?

A: The data strongly suggests the GPU is the bottleneck at 3840x2160. The FPS range from Low (95) to Ultra (44) is only 51 FPS, and the CPU’s benchmark scores (89th percentile among all CPUs) are far above what is needed for these frame rates. The GPU’s 71st percentile ranking among all GPUs aligns better with the observed 4K performance.

Q: What is the combo’s overall rank in this game?

A: The Ryzen 5 7500X3D and RX 6750 XT combination ranks 1275 out of 2828 tested combos in Lockdown Protocol, placing it in the top 45% of all system configurations. This is a mid-pack ranking, consistent with a GPU that is not top-tier for this title.

CPU Role

The Ryzen 5 7500X3D is a 6-core, 12-thread processor based on Zen 4 architecture on a 5 nm process. Its base clock is 4.00 GHz and boost clock is 4.50 GHz, with a 65 W TDP. The defining feature is the 96 MB shared L3 cache, which is unusual for a mainstream chip and directly benefits games that rely on large working sets. In synthetic benchmarks, the CPU scores 3494 in PassMark single-thread tests and 25047 in multithread tests, with a floating-point math score of 43594 and integer math score of 70774. These numbers place it in the 89th percentile of all CPUs, meaning it outperforms the vast majority of installed processors.

In Lockdown Protocol, the CPU’s role is most evident at 1080p Low, where the system reaches 200 FPS. That frame rate requires the CPU to process game logic and draw calls at a rate of 200 per second, which is feasible given the single-thread performance. The multithread score of 25047 suggests the 12 threads can handle background tasks and physics without interfering with the main render thread. The CPU’s nearest rival, the Intel Core i5-14600, scores 44889 (0.7% higher), but that difference is negligible in real-world gaming. The 96 MB L3 cache likely provides a hit-rate advantage in Lockdown Protocol’s map streaming and entity management, though the benchmark data does not isolate this effect. What the data does show is that at 1440p and 4K, the CPU’s performance ceiling is never reached—the FPS drops are entirely attributable to GPU load, not CPU limitations.

Measured FPS Breakdown

At 1920x1080, the measured rows are as follows: Low yields 200 FPS, Medium yields 142 FPS with a minimum of 121 and maximum of 164, High yields 124 FPS, and Ultra yields 93 FPS. The Medium preset provides the most complete data, showing a 43 FPS range between minimum and maximum, which indicates some frame pacing variance but no catastrophic drops. The jump from Low to Medium costs 58 FPS, while Medium to High costs 18 FPS, and High to Ultra costs 31 FPS. This non-linear scaling suggests that Medium is a sweet spot where the GPU is not yet overburdened, while Ultra adds effects that disproportionately impact throughput.

At 2560x1440, the numbers compress: Low gives 147 FPS, Medium gives 104 FPS (89 min, 120 max), High gives 91 FPS, and Ultra gives 68 FPS. The Medium preset again shows a 31 FPS variance between min and max, which is tighter than at 1080p. The drop from Low to Medium is 43 FPS, Medium to High is 13 FPS, and High to Ultra is 23 FPS. The reduced delta between Medium and High at 1440p suggests the GPU is becoming fill-rate limited, and the extra settings in High do not cost as much as they do at 1080p where the CPU can still push high frame rates.

At 3840x2160, the data shows: Low gives 95 FPS, Medium gives 67 FPS (57 min, 77 max), High gives 59 FPS, and Ultra gives 44 FPS. The Medium preset has a 20 FPS variance, which is the smallest absolute range across all resolutions. The drop from Low to Medium is 28 FPS, Medium to High is 8 FPS, and High to Ultra is 15 FPS. At this resolution, the GPU is clearly the limiting factor, and the small differences between Medium, High, and Ultra indicate that the card is running out of compute and memory bandwidth. The 4K Medium row with a 57 FPS minimum is the only 4K configuration that stays above 55 FPS, making it the only viable 4K option for smooth play.

GPU Role

The AMD Radeon RX 6750 XT is built on RDNA 2.0 architecture using a 7 nm process, with 17,200 million transistors on a 335 mm² die. It has 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray accelerators. The GPU runs at a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. Memory is 12 GB of GDDR6 on a 192-bit bus, providing 432.0 GB/s of bandwidth. The card’s pixel rate is 166.4 GPixel/s and texture rate is 416.0 GTexel/s, with FP32 performance of 13.31 TFLOPS. In synthetic benchmarks, it scores 20700 in PassMark G3D and 9550 in compute, placing it in the 71st percentile of all GPUs.

In Lockdown Protocol, the GPU’s role is defined by resolution scaling. At 1080p, the card can push 200 FPS on Low, but that drops to 93 FPS on Ultra—a 53.5% reduction. At 1440p, the range is 147 to 68 FPS, and at 4K, it is 95 to 44 FPS. The GPU’s nearest rival, the NVIDIA GeForce RTX 3080 Ti Mobile, scores 25740 (1.1% lower), and the AMD Radeon R9 M395X scores 25891 (0.5% higher). These are synthetic benchmark comparisons, but they suggest the RX 6750 XT is positioned near mid-range mobile parts in raw compute. The 12 GB VRAM is likely sufficient for Lockdown Protocol’s textures at 1440p, but at 4K Ultra, the combination of higher resolution and Ultra settings may be pushing against the 432.0 GB/s bandwidth limit. The data shows that Medium settings at 4K produce a 57 FPS minimum, which is playable, but anything above Medium drops below 60 FPS average. This points to the GPU’s compute and memory subsystem being the primary constraint at higher resolutions.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and frame rate goal. For 1920x1080, the Medium preset delivers 142 FPS average with a 121 FPS minimum, which is ideal for high-refresh monitors (120 Hz or higher). High settings at 124 FPS are also viable, but the 18 FPS cost over Medium may not justify the visual upgrade if you prioritize frame consistency. Ultra at 93 FPS is playable but sacrifices 49 FPS compared to Medium, which is a significant loss for a competitive FPS title.

For 2560x1440, Medium is the clear recommendation. It provides 104 FPS average with a 89 FPS minimum, keeping you above 60 FPS at all times. High settings at 91 FPS are close, but the 13 FPS difference is small enough that you could choose High if you prefer better visuals. Ultra at 68 FPS is borderline—it will feel smooth in most scenarios, but the lack of min/max data for Ultra means you risk frame drops below 60 FPS during intense firefights. Low at 147 FPS is unnecessary unless you are chasing maximum refresh rate on a 144 Hz monitor.

For 3840x2160, the options are limited. Low settings give 95 FPS, but the visual quality will be poor for a 4K display. Medium gives 67 FPS with a 57 FPS minimum, which is the only 4K preset that guarantees playability above 55 FPS. High at 59 FPS is just below the 60 FPS threshold, and Ultra at 44 FPS is too slow for a competitive shooter. The recommendation for 4K is Medium settings, accepting that you will need adaptive sync or a 60 Hz panel to avoid tearing. If you prioritize frame rate over resolution, dropping to 1440p Medium will give you a much smoother experience with 104 FPS. The data does not show any advantage to mixing settings, so the presets are the safest bet for this combo.
