Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 5 8400F + AMD Radeon RX 9070 XT

This combo ranks 874th out of 3,714 tested configurations in Lockdown Protocol, placing it in the top quarter of all tested systems. The pairing of a 6-core Zen 4 desktop processor with a RDNA 4.0 flagship GPU produces a balanced platform that scales predictably across resolutions, though the data reveals some interesting bottlenecks at the extremes. The measured frame rates show a system that can handle competitive FPS play at high refresh rates on 1080p and 1440p displays, while 4K remains playable but demands settings compromises.

How This Combo Ranks

The 874th position out of 3,714 combos places this configuration in the 76th percentile of all tested pairings for Lockdown Protocol. That is a strong showing, though not an elite one — the data suggests there are faster combinations available, but this system sits comfortably above the median experience. The CPU alone holds the 77th percentile among all processors, while the GPU sits at the 55th percentile among all graphics cards, which means the overall ranking is largely carried by the processor's strength relative to its peers.

What makes this ranking interesting is the delta between the two components' percentiles. The Ryzen 5 8400F outperforms 77% of all CPUs, while the RX 9070 XT only beats 55% of GPUs in the aggregate benchmark database. In Lockdown Protocol specifically, this combination still manages to crack the top quarter of tested systems, suggesting the game's engine rewards the CPU's single-thread and multi-thread capabilities more than raw GPU compute. The 3dmark results reinforce this: the CPU scores 6,165 in max-thread testing and 951 in single-thread, which are respectable figures that indicate strong per-core performance for a 6-core part.

Looking at the nearest rivals for each component clarifies the picture. The CPU's average benchmark score of 25,005 is nearly identical to the AMD Ryzen 5 7500F (24,964, just 0.2% behind) and the Intel Core i7-11850H (24,935, 0.3% behind). The GPU's average score of 13,543 is within 0.1% of the AMD Radeon HD 7770M and 0.2% of the NVIDIA GeForce GTX 570 — though those are older parts, the benchmark aggregates place them in similar territory. This suggests the RX 9070 XT's raw compute benchmarks may not fully capture its gaming performance, or that the game's workload differs significantly from synthetic tests.

CPU Role

The Ryzen 5 8400F brings 6 cores and 12 threads to the table, built on the Zen 4 architecture at a 4 nm process node. Its base clock of 4.20 GHz and boost clock of 4.70 GHz are competitive for a mainstream desktop part, and the 16 MB of shared L3 cache provides adequate data locality for game workloads. The 65 W TDP classifies it as an efficient processor, and the unlocked multiplier offers overclocking headroom, though the measured results reflect stock operation.

In Lockdown Protocol, the CPU's influence becomes apparent when examining the FPS scaling across settings at each resolution. At 1080p Low, the system hits 260 FPS average, which is a very high frame rate that suggests the CPU is feeding frames faster than most displays can show. The 3dmark 2-thread score of 1,874 and 4-thread score of 3,563 indicate that the processor's first few cores are strong, which matters for FPS titles that often rely on a handful of heavily utilized threads. The passmark single-thread score of 3,685 reinforces this — the 8400F handles lightly threaded workloads with ease.

The 25,000 million transistors packed into the 178 mm² die, produced by TSMC at 4 nm, represent a modern design that balances clock speed with power efficiency. The DDR5 memory support with dual-channel configuration and 83.2 GB/s bandwidth provides sufficient memory throughput for gaming, and the PCIe Gen 4 interface with 20 lanes gives the GPU adequate bandwidth without bottlenecking. The Cinebench R23 multicore score of 20,851 shows strong sustained multi-thread performance, while the single-core score of 2,943 confirms the per-thread strength that competitive FPS games demand.

FAQ

Q: How does this combo perform at 1080p compared to higher resolutions?

A: At 1080p, the average FPS ranges from 121 (Ultra) to 260 (Low), while at 1440p the range is 89 to 191, and at 4K it drops to 57 to 123. The scaling is not linear — 1080p Low delivers more than double the 4K Ultra frame rate.

Q: What is the best settings preset for competitive play?

A: The data shows 1080p Low achieves 260 FPS average, which is the highest measured frame rate. For players prioritizing maximum responsiveness, this setting provides the largest headroom above typical 144 Hz or 240 Hz displays.

Q: Does the CPU bottleneck the GPU at any resolution?

A: The performance drop from 1080p Low (260 FPS) to 1080p Ultra (121 FPS) is 53%, while the drop from 1440p Low (191 FPS) to 1440p Ultra (89 FPS) is also 53%. This consistent scaling suggests the CPU keeps pace as GPU load increases, though the 4K Ultra result of 57 FPS indicates the GPU becomes the limiting factor at the highest settings.

Q: How does the Ryzen 5 8400F compare to its nearest rival?

A: The 8400F's average benchmark score of 25,005 is just 0.2% higher than the AMD Ryzen 5 7500F (24,964) and 0.4% higher than the Intel Core i7-13620H (24,911). This places it in a very tight performance cluster where differences are negligible.

Q: Is the RX 9070 XT's performance consistent with its benchmark scores?

A: The GPU's passmark G3D score of 26,795 is strong, but its average benchmark score of 13,543 places it near the AMD Radeon HD 7770M (13,536) and NVIDIA GeForce GTX 570 (13,515). In Lockdown Protocol, the measured frame rates suggest the card performs well above what those aggregate scores might imply.

Q: What frame rates can players expect at 1440p with Medium settings?

A: The measured data shows 135 FPS average with minimums of 115 FPS and maximums of 156 FPS. This provides a smooth experience for high-refresh-rate 1440p monitors, with enough headroom to avoid dips below 100 FPS.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 260 FPS average, Medium reaches 185 FPS (minimum 157, maximum 212), High hits 161 FPS, and Ultra drops to 121 FPS. The spread from Low to Ultra is 139 FPS, representing a 53% reduction in performance when maxing out visual quality. The Medium preset's minimum of 157 FPS is notable — it stays above 144 Hz even during demanding scenes, which is critical for competitive play on high-refresh monitors.

Moving to 2560x1440, the frame rates remain strong but show expected scaling. Low settings deliver 191 FPS average, Medium achieves 135 FPS (minimum 115, maximum 156), High produces 118 FPS, and Ultra falls to 89 FPS. The percentage drop from 1080p to 1440p is roughly 27% across settings — from 260 to 191 at Low, 185 to 135 at Medium, 161 to 118 at High, and 121 to 89 at Ultra. This consistent reduction indicates balanced scaling rather than a sudden bottleneck.

At 3840x2160, the system still delivers playable frame rates but with more pronounced drops. Low settings reach 123 FPS average, Medium achieves 87 FPS (minimum 74, maximum 100), High produces 76 FPS, and Ultra drops to 57 FPS. The 4K results show that even the most demanding preset stays above 50 FPS, though the gap between Low and Ultra (66 FPS) is significant. The Medium preset's minimum of 74 FPS suggests that 4K gaming is viable but requires careful settings selection to maintain smoothness.

Resolution Scaling

The transition from 1080p to 1440p reduces average FPS by approximately 27% across all settings, while the step from 1440p to 4K cuts performance by roughly 36-37%. This steeper drop at 4K indicates that the RX 9070 XT's 16 GB of GDDR6 memory and 644.6 GB/s bandwidth start to become limiting factors at higher pixel counts. The GPU's boost clock of 2970 MHz and game clock of 2400 MHz provide solid raw throughput, but the 4K results show the card working harder to maintain frame rates.

The scaling pattern reveals important information about the limiting component. From 1080p Low (260 FPS) to 1080p Ultra (121 FPS), the 53% drop is entirely GPU-driven as settings increase. However, when moving from 1080p Ultra to 1440p Ultra (121 to 89 FPS, a 26% drop), the reduction is less severe than the 1440p to 4K transition at Ultra (89 to 57 FPS, a 36% drop). This suggests that at 1080p and 1440p, the CPU has enough headroom to keep the GPU fed, but at 4K the GPU's compute limits become the primary constraint.

The CPU's 83.2 GB/s memory bandwidth and dual-channel DDR5 support help maintain consistent frame delivery, but the data shows that higher resolutions increasingly rely on GPU memory bandwidth. The RX 9070 XT's 256-bit memory bus and 16 GB capacity are substantial, yet the 4K results indicate that the card's 48.66 TFLOPS FP32 performance is the ceiling — at 4K Ultra, the system averages only 57 FPS, which is just above the 50 FPS threshold many players consider acceptable for slower-paced titles.

Settings Recommendations

For players targeting 1080p at maximum refresh rates, the Low preset at 260 FPS is the clear choice for competitive play, offering more than double the frame rate of Ultra while maintaining responsiveness that fully utilizes 240 Hz displays. If visual fidelity matters more, the Medium preset at 185 FPS still provides excellent smoothness with improved image quality — the 157 FPS minimum ensures no drops below standard 144 Hz refresh rates.

At 1440p, the Medium preset at 135 FPS (minimum 115, maximum 156) emerges as the sweet spot for most players. It delivers a smooth experience on 144 Hz monitors with minimal risk of noticeable frame dips, while the High preset at 118 FPS is also viable for those who prioritize visual quality over raw speed. The Ultra preset at 89 FPS is playable but leaves little headroom for demanding scenes, making it less suitable for fast-paced competitive play.

For 4K gaming, the Low preset at 123 FPS is surprisingly strong and offers the best balance of smoothness and resolution, though it sacrifices significant visual detail. The Medium preset at 87 FPS (minimum 74) is the most balanced option for 4K, providing acceptable smoothness for most game types while maintaining better image quality. The High preset at 76 FPS is borderline, and Ultra at 57 FPS is only recommended for slower, visually focused experiences where frame rate is less critical.

GPU Role

The AMD Radeon RX 9070 XT is built on the RDNA 4.0 architecture with the Navi 48 chip, manufactured at 4 nm by TSMC with 53,900 million transistors on a 357 mm² die. Its 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is substantial for 4K gaming. The card's 4096 shading units, 256 texture mapping units, and 128 render output units deliver a pixel rate of 380.2 GPixel/s and a texture rate of 760.3 GTexel/s, enabling the high frame rates observed in the measured data.

The GPU's benchmark scores show a mixed picture. The 3dmark Steel Nomad DX12 score of 7,260 is strong, and the Geekbench Vulkan score of 65,879 is excellent, but the passmark G3D score of 26,795 and average benchmark score of 13,543 place it at the 55th percentile among all GPUs. The nearest rivals in the benchmark database — AMD Radeon HD 7770M (13,536, 0.1% behind), NVIDIA GeForce GTX 570 (13,515, 0.2% behind), and NVIDIA P106-090 (13,470, 0.5% behind) — are all much older architectures, which suggests the RX 9070 XT's aggregate scores may underrepresent its modern feature set.

In Lockdown Protocol specifically, the GPU's 16 GB VRAM capacity ensures no memory-related stuttering at any resolution, even at 4K Ultra. The boost clock of 2970 MHz and game clock of 2400 MHz provide high sustained performance, while the 304 W TDP and dual-slot design indicate a power-hungry but manageable card. The PCIe 5.0 x16 interface offers ample bandwidth, and the DirectX 12 Ultimate support ensures compatibility with modern rendering features. The 57 FPS at 4K Ultra and 260 FPS at 1080p Low demonstrate a wide dynamic range, with the card clearly capable of high-refresh 1080p gaming while remaining viable for 4K with appropriate settings adjustments.
