Lockdown Protocol

The AMD Ryzen 5 2600 and NVIDIA GeForce GTX 1660 Ti combination delivers a playable experience in Lockdown Protocol, but the data reveals sharp trade-offs between visual fidelity and frame rate. Across the measured presets, the sweet spot is Medium at 1920x1080, where the average frame rate reaches 87.3 FPS. This provides a substantial cushion above the 60 FPS threshold while retaining more visual detail than the Low preset. The High preset at 1080p drops to 79.4 FPS, which is still smooth, but the 9.4% penalty over Medium is notable for a modest visual gain. At 2560x1440, Medium is the only viable option for high-refresh displays, hitting 64.7 FPS, whereas High falls to 57.9 FPS, straddling the 60 FPS line. For 4K, the data suggests settling for Low, which produces 59.1 FPS—just shy of 60—while Medium and High crater to 40.6 and 33.6 FPS, respectively.

How This Combo Ranks

The measured combination ranks 1460th out of 1637 tested combos in Lockdown Protocol. This places it in the lower 11th percentile of all systems tested, indicating that while the pairing is functional, it sits far from the performance leaders. The CPU's percentileVsAllCpus of 77 is surprisingly strong for a processor from 2018, but the GPU's percentileVsAllGpus of 55 drags the overall experience down. Benchmark results indicate a system where the graphics card is the primary constraint at higher resolutions, yet the processor still holds its own in compute-heavy scenes. Compared to its nearest rivals, the GTX 1660 Ti sits within 0.8% of the AMD Radeon RX 570X, NVIDIA Tesla K10, and RTX A2000 Mobile, showing that this GPU is competitively positioned within its immediate performance bracket. The Ryzen 5 2600's nearest rivals—including the Intel Core i5-11600KF and i7-10700F—are separated by less than 1% in average benchmark score, meaning the CPU is not a bottleneck in most scenarios.

FAQ

Q: What is the best preset for 1080p gaming with this combo?

A: The Medium preset at 1920x1080 yields 87.3 FPS, which is the highest average above the 60 FPS mark that preserves medium-level visual detail. Low reaches 122.1 FPS but sacrifices too much visual quality, while High and Ultra drop to 79.4 and 56.3 FPS respectively.

Q: Can this system handle 1440p?

A: Yes, but only with compromises. The Medium preset at 2560x1440 produces 64.7 FPS, which is playable. The Low preset reaches 90.6 FPS for competitive play, but High and Ultra fall to 57.9 and 39.8 FPS, making them less ideal for smooth gameplay.

Q: Is 4K viable on this hardware?

A: Barely, and only on Low settings. The Low preset at 3840x2160 averages 59.1 FPS, just under the 60 FPS target. Medium drops to 40.6 FPS, and High falls to 33.6 FPS, making Ultra (26 FPS) effectively unplayable.

Q: How does the GPU's benchmark score compare to its rivals?

A: The GTX 1660 Ti scores 13,925 in the average benchmark, sitting just 0.4% above the AMD Radeon RX 570X and 0.8% below the NVIDIA Tesla K10. Its percentileVsAllGpus of 55 means it outperforms roughly half of all GPUs tested.

Q: What is the CPU's multithreaded performance like?

A: The Ryzen 5 2600 achieves 11,186 in Cinebench R23 multicore and 4,698 in R20 multicore, with a PassMark multithread score of 13,160. These figures support its 77th percentile ranking among all CPUs, indicating solid multi-threaded capability for its age.

Q: Does the memory bandwidth influence performance?

A: The CPU's dual-channel DDR4 support provides 46.9 GB/s of bandwidth, which is adequate for a 6-core/12-thread Zen+ processor. The GPU's 288.0 GB/s bandwidth is far higher, suggesting the system is not memory-starved in most gaming scenarios.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression: Low averages 122.1 FPS, Medium 87.3 FPS, High 79.4 FPS, and Ultra 56.3 FPS. The jump from Low to Medium is a 28.5% drop, while the jump from High to Ultra is a 29.1% drop, indicating that the Ultra preset imposes a steep cost for marginal visual improvements. At 2560x1440, Low hits 90.6 FPS, Medium 64.7 FPS, High 57.9 FPS, and Ultra 39.8 FPS. The delta between Medium and High at 1440p is just 10.5%, far smaller than the 14.4% drop seen at 1080p, suggesting diminishing returns from the High preset as resolution increases. At 3840x2160, Low yields 59.1 FPS, Medium 40.6 FPS, High 33.6 FPS, and Ultra 26 FPS. The gap between Low and Medium is 31.3%, the largest proportional drop across all resolutions, highlighting that 4K is only feasible with minimal settings.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a system heavily burdened by pixel count. At Low settings, the drop from 122.1 FPS at 1080p to 59.1 FPS at 4K represents a 51.6% reduction, which is close to the 4x pixel increase one might expect from a GPU-limited scenario. However, the scaling is not linear: 1440p Low (90.6 FPS) loses 25.8% of 1080p performance, while 4K Low loses another 34.8% from 1440p. This suggests the GTX 1660 Ti's 6 GB of GDDR6 memory and 192-bit bus are stretched at higher resolutions. At Ultra settings, the drop is even steeper: 56.3 FPS at 1080p falls to 39.8 FPS at 1440p (a 29.3% loss) and then to 26 FPS at 4K (a 34.7% loss). The data implies that the GPU's 5.437 TFLOPS of FP32 compute is the limiting factor at 4K, as the CPU's strong single-thread performance (1,579 in Cinebench R23 single-core) cannot compensate for the pixel fill rate demands.

CPU Role

The Ryzen 5 2600 brings 6 cores and 12 threads based on the Zen+ architecture, clocked at 3.40 GHz base and 3.90 GHz boost. Its cache hierarchy includes 96 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. In Lockdown Protocol, a fast-paced FPS, the CPU's single-thread performance is crucial. The Cinebench R23 single-core score of 1,579 places it in a competitive range for its generation, while the multicore score of 11,186 ensures background tasks do not interfere. The PassMark physics score of 673 suggests adequate game physics processing. However, the CPU's 77th percentile ranking versus all CPUs indicates it is not the primary bottleneck; at 1080p Low, where the GPU is less stressed, the CPU can feed frames up to 122.1 FPS, but at 4K, the GPU's limitations cap performance. The 16 MB of shared L3 is modest by today's standards, but for a 2024 FPS title, the data shows it is sufficient to avoid stuttering.

GPU Role

The GTX 1660 Ti is built on the Turing architecture with 1,536 shading units, 96 texture mapping units, and 48 ROPs. Its 6 GB of GDDR6 memory on a 192-bit bus delivers 288.0 GB/s of bandwidth, which is a key factor in texture-heavy scenes. The GPU clocks run at 1500 MHz base and 1770 MHz boost, producing 5.437 TFLOPS of FP32 compute. The PassMark G3D score of 12,871 and 3DMark Steel Nomad DX12 score of 1,061 reflect its mid-range positioning. In Lockdown Protocol, the GPU's 55th percentile ranking means it outperforms a slim majority of GPUs, but the measured FPS shows it struggles at 4K Ultra (26 FPS) and even 1440p Ultra (39.8 FPS). The 6 GB VRAM capacity is likely sufficient for 1080p and 1440p, but the data suggests that at 4K, the memory bandwidth and compute throughput become severe constraints. The GTX 1660 Ti's nearest rival, the AMD Radeon RX 570X, is within 0.4% in average score, confirming this GPU is at the edge of playability for modern FPS titles at high resolutions.
