Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 5 2600 + AMD Radeon RX 6650 XT

Lockdown Protocol, the 2024 FPS title, shows a clear performance hierarchy when paired with the AMD Ryzen 5 2600 and AMD Radeon RX 6650 XT. The measured frame rates across four resolutions and four quality presets reveal a system that is heavily GPU-bound at higher settings, while the CPU's 6-core, 12-thread configuration becomes a more significant factor at lower resolutions. The RX 6650 XT, built on RDNA 2.0 with 2048 shading units and 8 GB of GDDR6 memory on a 128-bit bus, delivers playable results in most scenarios, but the data indicates that users will need to make deliberate choices about resolution and settings to hit their preferred frame rate targets.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and consistent across all settings, confirming that the RX 6650 XT is the primary limiting component at higher resolutions. At Ultra settings, the average FPS falls from 76.3 at 1920x1080 to 54.7 at 2560x1440, a reduction of 28.3%, and then further to 37.3 at 3840x2160 — that is a 51.1% loss from 1080p to 4K. This steep decline is typical of a GPU with an 8 GB frame buffer and a 128-bit memory interface, where the 280.3 GB/s of bandwidth becomes strained by the pixel throughput required at 4K.

The scaling pattern at High settings tells a similar story. The system achieves 104.5 FPS at 1080p, drops to 75.7 FPS at 1440p (a 27.6% decrease), and lands at 47.6 FPS at 4K (a 54.4% decrease from 1080p). The consistency of these percentage drops across presets suggests that resolution scaling is governed by the GPU's raw pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s, rather than by any CPU-side bottleneck that would manifest differently at various resolutions.

At Low settings, the picture changes noticeably. The 1080p result of 163.7 FPS drops to 119.5 FPS at 1440p (27.0% lower) and 81.2 FPS at 4K (50.4% lower). While the percentage drops are similar to other presets, the absolute headroom at 1080p Low — over 160 FPS — indicates that the CPU can keep feeding frames well above typical refresh rates. The Ryzen 5 2600, with a base clock of 3.40 GHz and boost clock of 3.90 GHz, still manages to drive the system to high frame rates when the GPU is not the bottleneck.

The data indicates that 4K gaming is only viable at Low and Medium settings, where the system produces 81.2 and 57.0 FPS respectively. At High and Ultra, the 4K results of 47.6 and 37.3 FPS fall below the 60 FPS threshold that most FPS players consider acceptable. The limiting factor at 4K is unambiguously the GPU, as the gap between Low and Ultra at 4K (81.2 vs 37.3 FPS, a 54.1% difference) is nearly identical to the gap at 1080p (163.7 vs 76.3 FPS, a 53.4% difference), showing that the GPU's workload scales uniformly with settings regardless of resolution.

Settings Recommendations

For users targeting 60 FPS as the baseline, the measured data provides clear guidance. At 1920x1080, all four presets exceed 60 FPS, with High delivering 104.5 FPS and Ultra still managing 76.3 FPS. This makes 1080p the only resolution where Ultra settings are fully viable without compromise. At 2560x1440, the High preset produces 75.7 FPS, which is comfortable, while Ultra drops to 54.7 FPS — below the 60 FPS target. Medium at 1440p delivers 89.1 FPS, which is a strong middle ground for users who want higher resolution without sacrificing smoothness.

At 3840x2160, the situation inverts. Low settings produce 81.2 FPS, which is playable, but Medium drops to 57.0 FPS and High falls to 47.6 FPS. The Ultra preset at 4K is effectively unplayable at 37.3 FPS for a competitive FPS. The data suggests that 4K users should stick to Low settings if they prioritize frame rate, or accept a sub-60 FPS experience if visual fidelity is paramount.

The best experience per the measured rows is arguably 1440p High, which balances the 75.7 FPS average — well above the 60 FPS threshold — with the visual quality of the High preset. For users with high-refresh-rate monitors at 1080p, the Low preset's 163.7 FPS offers the maximum frame rate headroom, while Medium at 116.6 FPS still provides a substantial margin above 100 FPS. The Ultra preset at 1080p, at 76.3 FPS, represents the point where visual quality starts to cost meaningful frame rate, and users should consider whether the incremental quality gain over High is worth a 27.0% performance hit.

FAQ

Q: Can this system run Lockdown Protocol at 4K with playable frame rates?

A: Yes, but only at Low settings, where it averages 81.2 FPS. Medium at 4K drops to 57.0 FPS, and High and Ultra fall to 47.6 and 37.3 FPS respectively, which are below the 60 FPS target for most FPS players.

Q: What is the best preset for 1440p gaming?

A: High settings at 2560x1440 produce 75.7 FPS, which is the best balance of visual quality and performance above the 60 FPS threshold. Ultra at 1440p drops to 54.7 FPS, making it less suitable for fast-paced gameplay.

Q: How much frame rate is lost when moving from 1080p to 4K at High settings?

A: The average FPS drops from 104.5 at 1080p to 47.6 at 4K, a reduction of 54.4%. This indicates that the RX 6650 XT's 8 GB memory and 128-bit bus are significant constraints at higher resolutions.

Q: Is the Ryzen 5 2600 a bottleneck for this GPU in Lockdown Protocol?

A: The data suggests the GPU is the primary bottleneck at higher resolutions and settings. At 1080p Low, the system reaches 163.7 FPS, indicating the CPU can push frames well above typical refresh rates when the GPU workload is light.

Q: What frame rate can I expect at 1080p Ultra?

A: The average is 76.3 FPS, which is playable but noticeably lower than the 104.5 FPS at High settings. If you prioritize smoothness, dropping from Ultra to High yields a 27.0% performance increase.

Q: Does the system maintain 144 FPS at any resolution and preset combination?

A: No. The closest is 1080p Low at 163.7 FPS, which exceeds 144 FPS. At 1080p Medium, the average drops to 116.6 FPS, so only the lowest settings at 1080p can sustain frame rates above 144 FPS.

How This Combo Ranks

The AMD Ryzen 5 2600 + AMD Radeon RX 6650 XT combination ranks 1095 out of 1637 tested combos in Lockdown Protocol, placing it in the lower third of all configurations. This ranking reflects the age of the CPU, which was released in 2018 with a 12 nm process node and Zen architecture, combined with a mid-range GPU that sits at the 72nd percentile of all GPUs tested. The GPU's nearest rivals in synthetic benchmarks — the AMD Radeon RX 6800M, AMD Radeon RX 470, Intel Arc A370M, and AMD Radeon RX Vega M GH — all have average scores within 0.6% of the RX 6650 XT, meaning the GPU is competitive with a narrow band of mid-range parts, but the overall combo ranking is dragged down by the CPU.

The CPU's percentile of 77 against all CPUs is respectable, but its nearest rivals in average benchmark score — the Intel Core i5-1345U (0.4% faster), Intel Core i5-11600KF (0.6% faster), AMD Ryzen 5 7530U (0.6% slower), and Intel Core i7-10700F (0.7% slower) — are all more modern parts that offer better IPC. In a game like Lockdown Protocol, where frame rates at 1080p Low exceed 160 FPS, the CPU's 6 cores and 12 threads are sufficient to avoid being a hard bottleneck, but the 16 MB of shared L3 cache and dual-channel DDR4 memory bandwidth of 46.9 GB/s limit how far the system can push frame rates in CPU-bound scenarios.

The rank of 1095 out of 1637 means that roughly 542 tested combos perform worse, placing this system in a position where it can handle the game at reasonable settings but is far from the top tier. Users with higher-end CPUs paired with the same GPU would likely see better results at low resolutions, while users with stronger GPUs paired with this CPU would see improvements at higher resolutions. The measured data confirms that this combo is a balanced but aging pairing, suitable for 1080p and 1440p gaming at medium-to-high settings, but not for 4K beyond low presets.

CPU Role

The AMD Ryzen 5 2600 contributes 6 cores and 12 threads from the Zen architecture, produced on a 12 nm process node at GlobalFoundries. Its base clock of 3.40 GHz and boost clock of 3.90 GHz are modest by modern standards, and the 16 MB of shared L3 cache and 96 KB L1 cache per core are typical for the 2000 series. The CPU's synthetic benchmark scores — including a Cinebench R23 multi-core score of 11186 and single-core score of 1579 — place it at the 77th percentile of all CPUs, but its nearest rivals are all newer chips with higher IPC.

In Lockdown Protocol, the CPU's role becomes apparent when examining the frame rate scaling across resolutions. At 1080p Low, the system achieves 163.7 FPS, which is 50.4% higher than the 4K Low result of 81.2 FPS. This gap is largely due to the GPU's workload decreasing at lower resolutions, allowing the CPU to keep up. However, the fact that the 1080p Low result is 163.7 FPS — not higher — suggests that the Ryzen 5 2600's single-thread performance is a limiting factor when frame rates approach 165 FPS. The Cinebench R15 single-core score of 159 and R20 single-core score of 663 indicate that per-core performance is adequate but not exceptional.

The CPU's 12 threads help in scenarios where the game engine can parallelize work, but the PassMark multi-thread score of 13160 and physics score of 673 suggest that the CPU's overall compute throughput is modest. The memory bandwidth of 46.9 GB/s over a dual-channel DDR4 interface is another potential constraint, as Lockdown Protocol's FPS genre typically involves frequent asset streaming and physics calculations that rely on memory subsystem performance.

At higher resolutions and settings, the CPU's role diminishes because the GPU becomes the bottleneck. The 4K Ultra result of 37.3 FPS is likely determined almost entirely by the RX 6650 XT's ability to process pixels, not by the CPU's ability to issue draw calls. This is typical for an FPS title where resolution scaling has a larger impact on GPU load than on CPU load. The data shows that the Ryzen 5 2600 is a capable partner for the RX 6650 XT at 1440p and below, but users seeking the highest possible frame rates at 1080p would benefit from a CPU with higher single-thread performance. The combination of a 6-core, 12-thread CPU with a 2048-shader GPU represents a balanced mid-range build from the 2018-2022 era, and the benchmark results reflect that positioning in Lockdown Protocol.
