Summary
With an Intel Core i5-10400F paired with a Nvidia GeForce GTX 1660 Super at 1920x1080, this build lands in a clearly GPU-limited state. The supplied 46% bottleneck figure and critical severity line up with the average 38 FPS result: the i5-10400F still has enough headroom, but the GTX 1660 Super runs out of rendering power first at 1080p. In plain terms, the processor is usually ready with the next frame before the graphics card can finish drawing it. That makes this less of a CPU mismatch and more of a graphics ceiling. These calculator results are estimates rather than lab measurements, but the numbers point to the same conclusion: this pairing is workable for lighter games, yet it is underpowered for demanding modern titles at standard 1080p settings.
Performance Expectation
At 1080p FHD, an average of 38 FPS with lows around 27 FPS means you should expect a console-like feel in heavier games rather than consistently smooth PC performance. The Nvidia GeForce GTX 1660 Super will likely need medium settings, and in some newer titles you may need a mix of low and medium to keep frame dips under control. The Intel Core i5-10400F is not the part holding this system back here; the symptom of the bottleneck is not CPU stutter from game logic overload, but the GPU simply taking too long to render each frame. That shows up as sluggish response during busy scenes, bigger FPS drops when effects stack up, and less room to use higher texture filtering, shadows, or post-processing at 1920x1080.
Upgrade Advice
The numbers justify a GPU upgrade far more than a CPU change. Replacing the Intel Core i5-10400F would not solve the main issue when the Nvidia GeForce GTX 1660 Super is already the limiting component by 46% at 1080p. If you want smoother play, the graphics card is the part to address first. If you are staying with this build, lower the settings that hit the GPU hardest: shadows, volumetrics, ambient occlusion, and anti-aliasing usually matter more than trimming CPU-related options. One practical nuance many guides skip: on a card like the GTX 1660 Super, 1080p high presets can look attractive on paper but often produce worse consistency than a tuned medium preset with steadier frame times. Keep the i5-10400F unless you are also moving to a meaningfully faster GPU.
Best Use Case
This Intel Core i5-10400F and Nvidia GeForce GTX 1660 Super combination makes the most sense for esports games, older AAA releases, indie titles, and general everyday use at 1920x1080. In those workloads, the CPU is still competent and the GPU can deliver a decent experience if your target is modest settings and frame rates. It suits someone using a 60 Hz display who values playable performance over high visual presets. It is much less suitable for players expecting modern blockbuster games to sit comfortably above 60 FPS at 1080p, because the provided 38 FPS average simply does not support that expectation.
Warning
One caveat worth stating plainly: a 38 FPS average with a 27 FPS minimum can feel worse than the average suggests, because low-frame moments are what you actually notice during combat, driving, or dense city scenes. Also, the 46% bottleneck result is an estimate, not a bench result, so actual behavior will vary by game engine and settings. Even so, for an Intel Core i5-10400F and Nvidia GeForce GTX 1660 Super at 1080p, the broad message is reliable: the GPU is the clear limiting factor.
