Summary
At 1080p, the AMD Ryzen 5 5600G and Nvidia GeForce GTX 1660 Super are not a well-balanced match for modern demanding games if your target is smooth high-detail play. The key number here is the 46% bottleneck, with the GPU as the limiting part, and that lines up with the estimated 38 FPS average, 27 FPS minimum, and 49 FPS maximum. In plain terms, the Ryzen 5 5600G can keep feeding frames more effectively than the GTX 1660 Super can render them at this resolution. That makes this a graphics-limited build rather than a CPU-fed stutter problem. These calculator results are estimates, not lab measurements, but they point clearly in one direction: at 1080p, the GTX 1660 Super is the main cap on performance.
Performance Expectation
With the AMD Ryzen 5 5600G plus GTX 1660 Super at 1080p, expect newer AAA titles to require reduced settings to stay comfortable. An average around 38 FPS with lows near 27 FPS means you are likely to notice dips during heavy scenes, especially with complex lighting, dense effects, or large open areas. Because the GPU is the limiting component, the symptom is not usually the CPU struggling to feed data; it is more often the graphics card running out of rendering headroom, so frame rate falls as visual load rises. Lowering ray tracing is obvious, but on this class of card the more effective setting-level change is to cut shadow quality and resolution scale before touching texture quality. Actual results will vary by engine, drivers, cooling, graphics settings, background tasks, and whether the game leans heavily on VRAM or shader throughput.
Upgrade Advice
The numbers justify a GPU upgrade before anything else. A 46% GPU-side bottleneck at 1080p is too large to ignore, while the Ryzen 5 5600G still has enough life for a midrange graphics upgrade in most gaming builds. I would not rush to replace the CPU first, because that would not address the estimated 38 FPS average tied directly to the GTX 1660 Super. If you need to keep this system as-is for now, use 1080p with reduced shadows, lighter post-processing, and a modest resolution-scale drop in the heaviest games. One caveat many guides skip: the 5600G has less L3 cache than a standard Ryzen 5 5600, so after a GPU upgrade some CPU-sensitive games may still show lower peak frame rates than expected, but the current weakness is still clearly the GTX 1660 Super.
Best Use Case
This AMD Ryzen 5 5600G and GTX 1660 Super combination at 1080p makes the most sense for mixed use: esports titles, older AAA games, indie games, media work, and everyday desktop tasks. It is also reasonable for players who prioritize cost control and are willing to tune settings instead of chasing high refresh rates in demanding releases. The build is less suited to users expecting modern 1080p ultra settings with consistently smooth frame delivery. The estimated 38 FPS average suggests it works best when visual settings are chosen carefully rather than pushed aggressively.
Warning
Do not read the 46% bottleneck figure as a fixed real-world measurement. It is an estimate, and some games will perform better or worse than the 38 average, 27 minimum, and 49 maximum depending on engine behavior, driver maturity, cooling, RAM setup, and background activity. Also, if the Ryzen 5 5600G is running single-channel memory, performance consistency can drop further, which can make the GTX 1660 Super feel even more constrained at 1080p.
