Lockdown Protocol

The AMD Ryzen 5 5600GT paired with the NVIDIA GeForce RTX 4090 lands at rank 76 out of 1,637 tested combos in Lockdown Protocol. That places this pairing in the top 4.6% of all configurations evaluated for this FPS title, which is a strong showing given the mismatch in tier between the CPU and GPU. The data indicates that this combo is held back by the processor, but the sheer power of the flagship graphics card keeps results competitive.

How This Combo Ranks

At rank 76 out of 1,637 combos, this Ryzen 5 5600GT + RTX 4090 setup is firmly in the upper echelon of tested systems for Lockdown Protocol. The combination outperforms roughly 95% of all tested pairings in this database. This ranking reflects the overall frame delivery across all resolutions and settings tested, not just peak 1080p numbers.

The CPU is the weak link in this pairing. It sits in the 78th percentile against all CPUs in the database, with an average benchmark score of 20,740. Its nearest rivals in CPU benchmarks show how tight the mid-range competition is: the Intel Core i7-10700 scores 20,746 (0% delta), the AMD Ryzen 5 5600X scores 20,680 (+0.3% delta), and the Intel Core i5-12490F scores 20,794 (-0.3% delta). The 5600GT essentially trades blows with these alternatives, meaning the processor’s contribution to the combo ranking is consistent with other strong six-core options.

The GPU, by contrast, is a monster. It ranks in the 91st percentile among all GPUs with an average benchmark score of 66,473. Its nearest GPU rivals include the NVIDIA Tesla T4 at 66,733 (-0.4% delta), the AMD Radeon Pro Vega 56 at 67,097 (-0.9% delta), and the NVIDIA Quadro P6000 at 67,320 (-1.3% delta). The RTX 4090’s raw compute advantage is what pushes this combo to the top despite the CPU’s modest standing.

GPU Role

The NVIDIA GeForce RTX 4090 brings 24 GB of GDDR6X memory across a 384-bit bus, yielding 1.01 TB/s of bandwidth. Memory clocks run at 1,313 MHz, which translates to 21 Gbps effective. The GPU’s boost clock is 2,520 MHz with a base clock of 2,235 MHz. These specifications drive its 82.58 TFLOPS of FP32 performance, which is the engine behind Lockdown Protocol’s high frame rates.

In this game, the GPU’s role shifts dramatically with resolution. At 1080p and 1440p, the RTX 4090 is largely underutilized because the CPU cannot feed it enough frames. Evidence of this appears in the 1080p Low setting result: 263.8 FPS average. That is not a GPU-bound number; it is a CPU ceiling. The RTX 4090 is capable of far more in lighter titles. At 4K Ultra, the GPU finally gets to stretch its legs, producing 84.1 FPS, which is entirely respectable for a demanding setting.

The 24 GB VRAM is overkill for Lockdown Protocol at any tested setting. Even at 4K Ultra, the game does not approach the memory capacity limit. The practical benefit of the RTX 4090 here is its raw shading power, not its memory pool. The 512 texture mapping units and 176 render output units handle the game’s visual effects with ease. The 128 ray tracing cores are present but this game’s benchmark results do not isolate RT performance.

CPU Role

The AMD Ryzen 5 5600GT uses the Zen 3 architecture on a 7 nm TSMC process, featuring 6 cores and 12 threads. Base clock is 3.60 GHz with a boost clock of 4.60 GHz. The CPU has 16 MB of L3 cache, with 512 KB L2 per core and 64 KB L1 per core. It supports DDR4 memory in dual-channel configuration with 51.2 GB/s of bandwidth. This is a 65 W TDP part on the AM4 socket with PCIe Gen 3 connectivity.

In Lockdown Protocol, the CPU’s 6 cores and 12 threads matter most at lower resolutions. At 1080p Low, the average FPS of 263.8 is clearly processor-limited. The 3DMark single-thread score of 913 and multi-thread score of 5,554 indicate this is not a weak processor, but it is not in the same league as the GPU. The Cinebench R23 multi-core score of 17,272 and single-core score of 2,438 confirm a solid mid-range part.

The CPU’s boost clock of 4.60 GHz helps keep frame pacing consistent in a fast-paced FPS. However, the PCIe Gen 3 interface is a potential bottleneck for the RTX 4090, which is a PCIe 4.0 card. In this game, the impact appears minimal based on the measured results, but the architecture limits future-proofing. The 5600GT’s 3DMark 16-thread score of 5,523 shows it scales adequately with full thread utilization, which matters in multiplayer FPS scenarios with many players on screen.

Measured FPS Breakdown

The measured FPS data across resolutions and settings tells a clear story. At 1920x1080, the results are: Low 263.8 FPS, Medium 230.8 FPS, High 219.2 FPS, and Ultra 170.5 FPS. The gap between Low and Ultra is 93.3 FPS, showing that even at this resolution, settings have a significant impact on the CPU-bound frame rate.

At 2560x1440, the results are: Low 238.7 FPS, Medium 193.3 FPS, High 165.3 FPS, and Ultra 127.8 FPS. The step from Low to Medium is a 45.4 FPS drop, while the step from High to Ultra is 37.5 FPS. The 1440p numbers remain high, but the GPU is starting to take over the workload.

At 3840x2160, the results are: Low 176 FPS, Medium 123.4 FPS, High 106.9 FPS, and Ultra 84.1 FPS. At 4K, the GPU is fully engaged. The difference between Low and Ultra is 91.9 FPS, which is nearly identical in magnitude to the 1080p spread. This suggests that the RTX 4090’s scaling across settings is consistent, while the CPU’s influence fades.

The most striking number is 1080p Low at 263.8 FPS. This is a hard ceiling imposed by the 5600GT’s single-thread performance. Meanwhile, 4K Ultra at 84.1 FPS is a GPU-bound result that remains perfectly playable on high-refresh displays with VRR.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the bottleneck shift. Starting with Low settings: 1080p Low runs at 263.8 FPS, 1440p Low drops to 238.7 FPS (a 9.5% decrease), and 4K Low falls to 176 FPS (a 33.3% decrease from 1080p). The 4K to 1080p ratio of 0.67 shows that even at low settings, the GPU is doing meaningful work.

For High settings: 1080p High runs at 219.2 FPS, 1440p High drops to 165.3 FPS (a 24.6% decrease), and 4K High falls to 106.9 FPS (a 51.2% decrease from 1080p). This steep drop indicates the GPU becomes the primary limiter as resolution increases.

For Ultra settings: 1080p Ultra runs at 170.5 FPS, 1440p Ultra drops to 127.8 FPS (a 25.1% decrease), and 4K Ultra falls to 84.1 FPS (a 50.7% decrease from 1080p). The consistent 50% drop from 1080p to 4K across High and Ultra settings confirms that the RTX 4090 is the limiting factor at 4K.

The interpretation is straightforward: at 1080p, the CPU is the bottleneck, as evidenced by the relatively small FPS differences between Low and Medium settings (263.8 to 230.8 FPS). At 4K, the GPU is the bottleneck, with the CPU’s role diminished. For users targeting 1440p high refresh, this combo delivers excellent results, but 4K Ultra is the GPU’s domain.

FAQ

Q: Is the RTX 4090 wasted with the Ryzen 5 5600GT in Lockdown Protocol?

A: Not entirely, but the CPU caps performance at 1080p. At 1080p Low, the combo reaches 263.8 FPS, which is likely a CPU limit. At 4K Ultra, the GPU is fully utilized at 84.1 FPS, showing the RTX 4090’s value at higher resolutions.

Q: What is the best resolution for this combo in this game?

A: The data suggests 1440p is the sweet spot. At 1440p High, the combo delivers 165.3 FPS, which is smooth on high-refresh monitors. At 4K High, the average drops to 106.9 FPS, which is still playable but not as consistently high.

Q: How much of a difference does the Ultra preset make compared to Low?

A: At 1080p, the difference between Low and Ultra is 93.3 FPS (263.8 vs 170.5). At 4K, the difference is 91.9 FPS (176 vs 84.1). The absolute FPS gap is consistent, but the percentage drop is larger at 4K.

Q: Does the CPU bottleneck disappear at higher resolutions?

A: Yes. The FPS drop from 1080p to 4K is 33.3% at Low settings but 51.2% at High settings. This larger drop at higher settings indicates the GPU becomes the limiting factor as resolution increases, reducing the CPU’s influence.

Q: How does the CPU compare to its closest rivals?

A: The Ryzen 5 5600GT scores 20,740 in average benchmarks. The Intel Core i7-10700 scores 20,746 (0% delta), the AMD Ryzen 5 5600X scores 20,680 (+0.3% delta), and the Intel Core i5-12490F scores 20,794 (-0.3% delta). Performance is essentially identical among these.

Q: Is this combo ranked highly among all tested systems?

A: Yes. It ranks 76th out of 1,637 tested combos for Lockdown Protocol, placing it in the top 4.6% of all configurations. The GPU’s 91st percentile standing among all GPUs is the primary driver of this high rank.
