Lockdown Protocol

# Lockdown Protocol with Intel Core i5-13400F + AMD Radeon RX 6600 XT

The combination of the Intel Core i5-13400F and AMD Radeon RX 6600 XT produces a playable but resolution-sensitive experience in Lockdown Protocol. The measured frame rates show a clear pattern: this pairing is strongest at 1080p, where it delivers triple-digit averages at lower settings, but it becomes increasingly GPU-bound as resolution climbs. At 4K Ultra, the system falls to 36.4 FPS, indicating the RX 6600 XT's 8 GB frame buffer and 128-bit memory interface are the limiting factors in this FPS title. The data places this combo at rank 1130 out of 1637 tested combinations, a mid-pack result that reflects the GPU's position in the broader hardware landscape.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, pointing to a clear GPU bottleneck at higher resolutions. At Low settings, the average FPS falls from 157.3 at 1920x1080 to 76.1 at 3840x2160 — a 51.6% reduction. This scaling is nearly linear with pixel count, which is characteristic of a system where the graphics card is doing the heavy lifting. The RX 6600 XT's 256.0 GB/s of memory bandwidth and 8 GB GDDR6 frame buffer become progressively more strained as resolution increases, and the data reflects this.

At Medium settings, the drop is from 114.2 FPS at 1080p to 53.9 FPS at 4K, a 52.8% decrease. High settings show a similar pattern: 99.1 FPS at 1080p versus 48.4 FPS at 4K, a 51.2% reduction. The consistency of these percentages across settings levels suggests that resolution scaling is the dominant factor, not the specific quality preset. The one anomaly is Ultra settings, where the 1080p result of 76.5 FPS drops to 36.4 FPS at 4K — a 52.4% decline. Even at 1440p, the Ultra preset manages only 57 FPS, which is below the 60 FPS threshold many players target.

The scaling behavior reveals that the CPU, with its 10 cores and 16 threads, is not the limiting component in this game. If the i5-13400F were the bottleneck, we would expect to see smaller FPS gaps between 1080p and 4K, as the GPU would be less stressed at lower resolutions. Instead, the near-identical percentage drops across all settings indicate that the RX 6600 XT is saturated well before the CPU's 4.60 GHz boost clock becomes a constraint.

How This Combo Ranks

The combo's position at rank 1130 out of 1637 tested configurations places it in the lower-middle tier of the database. This is a percentile standing of roughly 31% from the top, meaning about two-thirds of tested combos deliver higher frame rates in Lockdown Protocol. The ranking is heavily influenced by the GPU's overall benchmark percentile of 71, which puts the RX 6600 XT above 71% of all tested graphics cards. The CPU, by contrast, sits at the 82nd percentile among all processors, indicating it is the stronger component in this pairing.

The CPU's nearest rivals help contextualize its performance. The Intel Core i7-13620H scores 25201, a mere 0.1% behind the i5-13400F's average benchmark score of 25236. The AMD Ryzen 5 5600X3D scores 25365, a 0.5% advantage, while the AMD EPYC 9474F and AMD Ryzen AI 5 PRO 340 both sit within 0.5% of the i5-13400F's score. This tight clustering shows that the CPU's computational throughput is well within the expected range for its class, and it is not the reason the combo ranks in the 1130th position.

The GPU's rival comparisons are more telling. The NVIDIA GeForce GTX 980 Ti scores 27956, just 0.1% below the RX 6600 XT's average of 27985. The AMD Radeon R9 M395X sits at 27883, a 0.4% deficit, while the NVIDIA GeForce RTX 3070 leads by 0.9% with a score of 28238. These margins are small, but in a game like Lockdown Protocol where frame rates in the 60-100 range are common, even a 1% difference can translate to a meaningful FPS shift at the margin.

GPU Role

The AMD Radeon RX 6600 XT is the decisive component in this combo's Lockdown Protocol performance. Its 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth, which is modest by modern standards but adequate for 1080p gaming. The card's boost clock of 2589 MHz and game clock of 2359 MHz are relatively high, yet the 2048 shading units and 64 ROPs limit its fill rate to 165.7 GPixel/s. These specifications explain why the card excels at lower resolutions but struggles at 4K.

The GPU's benchmark scores reflect its mid-range positioning. Its PassMark G3D score of 16461 and 3DMark Steel Nomad score of 1804 are consistent with a card that sits at the 71st percentile among all GPUs. The Geekbench OpenCL score of 82736 and Vulkan score of 89263 indicate solid compute capabilities, but these do not translate to 4K gaming performance. The 10.60 TFLOPS of FP32 compute is respectable, yet the memory subsystem becomes the limiting factor when pixel count quadruples from 1080p to 4K.

The 4K Ultra result of 36.4 FPS is particularly telling. This is the only resolution/settings combination that falls below the 40 FPS threshold, and it suggests that the 8 GB frame buffer is being fully utilized at this setting. The transition from 1440p Ultra at 57 FPS to 4K Ultra at 36.4 FPS is a 36.1% drop, which is larger than the resolution scaling percentage seen at other settings. This indicates that the card's memory bandwidth is insufficient for 4K Ultra in this title, regardless of the CPU's capabilities.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 157.3 FPS, Medium hits 114.2 FPS, High reaches 99.1 FPS, and Ultra manages 76.5 FPS. These numbers show that the system can comfortably handle 1080p gaming at any quality preset, with even the most demanding settings staying well above the 60 FPS mark. The gap between Low and Ultra is 80.8 FPS, demonstrating that settings have a substantial impact at this resolution.

Moving to 2560x1440, the frame rates remain playable but the margins tighten. Low settings deliver 117.3 FPS, a 25.4% drop from 1080p. Medium produces 84.6 FPS, High reaches 74.1 FPS, and Ultra falls to 57 FPS. The Ultra result at 1440p is the first instance where the combo dips below 60 FPS, and it signals that 1440p gaming requires careful settings management. The difference between Low and Ultra at this resolution is 60.3 FPS, a smaller gap than at 1080p, indicating that the GPU is becoming the limiting factor.

At 3840x2160, the limitations become apparent. Low settings yield 76.1 FPS, which is still playable, but Medium drops to 53.9 FPS, High falls to 48.4 FPS, and Ultra drops to 36.4 FPS. The 4K results show a clear hierarchy: only Low settings provide a consistently smooth experience, while Ultra is effectively unplayable for competitive play. The scaling from Low to Ultra at 4K is a 39.7 FPS difference, the smallest absolute gap across all resolutions, confirming that the GPU's memory bandwidth is the primary constraint.

CPU Role

The Intel Core i5-13400F provides ample computational headroom for Lockdown Protocol. Its 10 cores and 16 threads, based on Raptor Lake architecture, deliver a Cinebench R23 multi-core score of 21279 and a single-core score of 3004. The 3DMark 16-thread score of 7314 and max-thread score of 7307 indicate that the CPU can handle heavily threaded workloads without becoming a bottleneck. With a base clock of 2.50 GHz and boost clock of 4.60 GHz, the processor has sufficient frequency headroom for gaming workloads.

The CPU's PassMark multi-thread score of 25032 places it at the 82nd percentile among all processors, and its nearest rivals are all within 0.5% of its average score. This performance parity means that the i5-13400F is not distinguishing itself as either a strength or weakness in this combo. The 20 MB of shared L3 cache and dual-channel memory support for DDR4 and DDR5 provide adequate memory bandwidth for the game's data requirements.

The benchmark data shows that the CPU is not the limiting factor at any resolution or settings combination. At 1080p Low, where the system achieves 157.3 FPS, the CPU is capable of feeding the GPU fast enough to maintain that frame rate. Even at 4K Ultra with 36.4 FPS, the CPU has substantial headroom remaining. The PassMark single-thread score of 3634 and Geekbench single-core score of 2301 indicate that the processor can handle the game's main thread without issue. The 65 W TDP and 10 nm process node suggest that thermal throttling is unlikely to be a concern, allowing the CPU to maintain its boost clock during extended gaming sessions.
