Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 7 9700F + AMD Radeon RX 6600

Lockdown Protocol, a 2024 FPS title, presents a demanding workload that scales predictably with resolution and settings when paired with the AMD Ryzen 7 9700F and AMD Radeon RX 6600. The measured frame rates across the three primary resolutions reveal a system that delivers playable performance at 1080p, becomes increasingly strained at 1440p, and falls below smooth thresholds at 4K. This combination of an 8-core Zen 5 processor with a last-generation RDNA 2 graphics card produces a predictable bottleneck structure: the GPU governs high-resolution and high-detail scenarios, while the CPU provides ample headroom that only becomes relevant at lower settings and resolutions. The data indicates a balanced pairing for 1080p gaming, with clear limitations emerging as pixel count rises.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 demonstrates classic GPU-bound scaling behavior. At Low settings, the average FPS drops from 146 at 1080p to 107 at 1440p—a 27% reduction—and then further to 69 at 4K, representing a 53% drop from the 1080p baseline. This steep decline at 4K strongly indicates that the Radeon RX 6600's rendering throughput, rather than the Ryzen 7 9700F's compute capability, is the limiting factor as resolution increases. The pixel count quadruples from 1080p to 4K, yet the frame rate does not quarter, which suggests the CPU is compensating somewhat at the highest resolution, but the GPU remains the primary constraint.

At High settings, the scaling is similar but with lower absolute values: 90 FPS at 1080p, 66 FPS at 1440p, and 43 FPS at 4K. The percentage drops between resolutions are 27% (1080p to 1440p) and 35% (1440p to 4K), showing a slightly gentler curve than at Low settings. This is counterintuitive at first glance—higher settings should amplify GPU load—but it reflects the fact that at Low settings, the CPU can feed frames fast enough to expose the GPU's raw limits more directly. At High settings, the added shading and texture work creates a more balanced load, though the GPU still dominates the bottleneck.

Ultra settings produce the most dramatic scaling: 68 FPS at 1080p, 50 FPS at 1440p, and 32 FPS at 4K. The 4K result is 53% below the 1080p figure, matching the Low-setting drop percentage almost exactly. This consistency across the settings spectrum indicates that resolution scaling is governed by the GPU's fill rate and memory bandwidth—the RX 6600's 159.4 GPixel/s pixel rate and 224.0 GB/s bandwidth—rather than by any settings-specific feature. The 8 GB GDDR6 frame buffer also comes into play at 4K Ultra, where memory capacity pressure can cause additional performance degradation beyond raw compute limits.

The Medium settings data, which includes minimum and maximum frame times, provides insight into frame pacing at each resolution. At 1080p Medium, the average is 103 FPS with a minimum of 88 and maximum of 119, a spread of 31 FPS. At 1440p Medium, the average drops to 76 FPS with a 64 minimum and 87 maximum, a 23 FPS spread. At 4K Medium, the average is 49 FPS with a 42 minimum and 56 maximum, a 14 FPS spread. This tightening of the range at higher resolutions suggests that as the GPU becomes more saturated, frame times become more consistent because the CPU is less likely to cause stutter. At lower resolutions, the CPU can occasionally deliver frames faster than the GPU can process, creating micro-stutters that widen the min-max range.

CPU Role

The AMD Ryzen 7 9700F is built on the Zen 5 architecture (Granite Ridge) using a 4 nm TSMC process, with 8 cores and 16 threads. Its base clock of 3.80 GHz and boost clock of 5.50 GHz provide substantial single-thread performance, reflected in its Passmark single-thread score of 4691. This processor sits in the 94th percentile of all CPUs, meaning it outperforms the vast majority of installed processors. In Lockdown Protocol, an FPS title that typically relies on a few heavily utilized threads, this strong single-thread showing ensures the CPU does not become the primary bottleneck at most settings.

The 32 MB shared L3 cache and 80 KB L1 cache per core contribute to low-latency access to frequently used game data. The processor's 89.6 GB/s memory bandwidth on a dual-channel DDR5 interface provides sufficient data throughput for the game's asset streaming. However, the measured FPS data shows that the CPU's role diminishes as resolution increases. At 1080p Low, where the GPU has the least work per frame, the 146 FPS average demonstrates that the Ryzen 7 9700F can feed frames fast enough to approach the GPU's maximum output. At 4K Ultra, the 32 FPS result is almost entirely GPU-limited, as the CPU is waiting for the graphics card to finish each frame.

The Ryzen 7 9700F's nearest rivals in aggregate benchmark scores provide context for its overall capability. It scores within 0.2% of the AMD Ryzen 9 7940HX and within 0.7% of the AMD Ryzen 9 7950X, while being 0.2% behind the Intel Core i7-14700KF. In Lockdown Protocol specifically, the game's engine appears to favor the Zen 5 architecture's high IPC (instructions per cycle), as the 1080p results show no signs of CPU limitation even at High settings with 90 FPS. The Passmark multithread score of 36470 and integer math score of 120788 indicate that even if the game were to scale to more threads, this CPU has ample headroom.

The CPU's 65 W TDP and 4 nm process node mean it operates efficiently without thermal throttling concerns in most scenarios. This is relevant to Lockdown Protocol's sustained performance in long gaming sessions, as the boost clock of 5.50 GHz can be maintained without power limits being hit. The data shows no evidence of frame rate degradation over time, which would typically indicate thermal or power throttling.

How This Combo Ranks

In the database of tested combinations for Lockdown Protocol, this pairing of AMD Ryzen 7 9700F and AMD Radeon RX 6600 ranks 2901 out of 3714 total combinations. This places it in the bottom 22% of all tested systems, which is a direct consequence of the RX 6600's modest standing in the GPU hierarchy. The graphics card sits in the 63rd percentile of all GPUs, but in a modern FPS like Lockdown Protocol, the demanding rendering workload pushes this card down the performance ladder.

The combo rank of 2901 indicates that most other CPU-GPU pairings deliver higher frame rates in this title. This is expected given that the RX 6600 is an end-of-life product from 2021, while Lockdown Protocol was released in 2024. The GPU's nearest rivals in aggregate score—the NVIDIA Quadro K6000 (0% delta), GeForce RTX 4050 Mobile (-0.1%), and Tesla K20m (-0.3%)—are all either workstation parts or mobile variants, none of which are optimized for gaming performance in the same way as dedicated desktop gaming GPUs.

The CPU's high percentile ranking (94th) means that in other games less dependent on GPU performance, this combination could rank much higher. However, in Lockdown Protocol, the GPU's limitations cap the system's potential. The 2901st rank out of 3714 combos suggests that users with this pairing are likely experiencing frame rates that are adequate for casual play at 1080p but fall short of competitive or high-refresh-rate standards.

When examining the rank in the context of the measured FPS, a clear pattern emerges: the combo performs proportionally better at lower resolutions and settings. At 1080p Low, the 146 FPS average would likely place this combination significantly higher in the rankings if that were the only metric considered. However, the database rank likely aggregates performance across all tested conditions, pulling the overall position down due to weak 4K performance. The 4K Ultra result of 32 FPS is below the 30 FPS minimum playability threshold for many users, and even the 4K Medium average of 49 FPS is marginal.

Measured FPS Breakdown

At 1920x1080, the RX 6600 delivers its best results in Lockdown Protocol. The Low preset produces an average of 146 FPS, which is suitable for high-refresh-rate monitors. Medium settings yield 103 FPS average with a minimum of 88 and maximum of 119, providing a smooth experience on standard 60 Hz displays with room to spare. High settings reduce the average to 90 FPS, still comfortably above 60 FPS. Ultra settings drop to 68 FPS average, which is playable but shows the GPU beginning to struggle with the highest-quality textures and effects.

At 2560x1440, the performance envelope tightens considerably. Low settings produce 107 FPS average, which is still smooth but represents a significant 27% drop from 1080p. Medium settings average 76 FPS with a minimum of 64 and maximum of 87, putting the minimum just at the threshold of acceptable for most players. High settings average 66 FPS, which is borderline for smooth gameplay. Ultra settings drop to 50 FPS average, which is below the ideal 60 FPS target but still technically playable in a non-competitive context.

At 3840x2160, the RX 6600's limitations become starkly apparent. Low settings average 69 FPS, which is the only 4K preset that approaches a smooth experience. Medium settings average 49 FPS with a minimum of 42 and maximum of 56, which is noticeably choppy. High settings produce 43 FPS average, and Ultra drops to 32 FPS average. The 8 GB VRAM is likely a contributing factor at 4K, as the higher-resolution textures exceed the card's memory capacity, forcing asset swapping that further reduces performance.

The Medium settings data provides the most complete picture, as it includes minimum and maximum frame times. At 1080p Medium, the 88 FPS minimum ensures that even demanding scenes stay fluid. At 1440p Medium, the 64 FPS minimum is the lowest acceptable threshold for many gamers. At 4K Medium, the 42 FPS minimum would cause noticeable stuttering in fast-paced FPS gameplay. The spread between minimum and maximum at each resolution—31 FPS at 1080p, 23 FPS at 1440p, and 14 FPS at 4K—indicates that frame pacing becomes more consistent as resolution increases, but only because the average frame rate is lower, compressing the range.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture (Navi 23 chip) using a 7 nm TSMC process. It features 1792 shading units, 112 texture mapping units, and 64 render output units. The boost clock of 2491 MHz and game clock of 2044 MHz provide respectable compute performance for its class, with an FP32 rating of 8.928 TFLOPS. However, in Lockdown Protocol, these specifications translate to the performance envelope described above, which is increasingly insufficient as settings and resolution increase.

The GPU's 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth. This memory configuration is a significant limiting factor at 4K resolution, where the bandwidth requirement for high-resolution textures and effects exceeds what the card can deliver. The 159.4 GPixel/s pixel rate and 279.0 GTexel/s texture rate determine how quickly the GPU can fill the screen and apply textures, and these rates are simply too low for 4K gaming at high settings.

The RX 6600's nearest rivals in aggregate benchmark scores show it performs almost identically to the NVIDIA Quadro K6000 (0% delta) and is within 0.3% of the Tesla K20m. It is slightly ahead of the RTX 2000 Ada Generation by 0.4% and slightly behind the GeForce RTX 4050 Mobile by 0.1%. These comparisons indicate that in raw compute terms, the RX 6600 is competitive with a range of older workstation and newer mobile parts, but none of these are top-tier gaming GPUs.

The GPU's 63rd percentile ranking among all GPUs places it in the mid-range of the performance spectrum. In Lockdown Protocol, this translates to a card that can handle 1080p gaming at high settings with good frame rates, 1440p at medium settings with acceptable performance, and 4K only at low settings. The DirectX 12 Ultimate support (12_2) ensures compatibility with modern rendering features, and the 28 ray tracing cores provide some RT capability, though the 8.928 TFLOPS FP32 compute is not sufficient for heavy RT workloads in this game.

The RX 6600's 132 W TDP and dual-slot design, with a single 8-pin power connector, make it an efficient card that runs cool and quiet. The PCIe 4.0 x8 interface provides adequate bandwidth for the card's memory pool, and the 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs support modern displays. However, none of these features compensate for the fundamental compute and memory bandwidth limitations that cap performance in Lockdown Protocol's most demanding settings.
