Does the GTX 1660 Super bottleneck?
No, basically never. The GTX 1660 Super tops out around 68 FPS in demanding games at 1080p, and every processor worth pairing with a graphics card this old clears that number with room left over. If anything is holding your frame rate down, it's the card itself, not the chip next to it.
The short answer
Complete your build
Everything else your GTX 1660 Super build needs, sized to the card.
People ask about a CPU bottleneck on the GTX 1660 Super for the wrong reason: they assume any budget part must be starved by something. It's backwards here. This card was built to be the affordable option, and its own ceiling sits well under what a mid-range or older six-core processor can supply. There isn't much room for a CPU to get in the way.
Even the oldest chip in our current pairing data, a Ryzen 5 3600, comfortably outruns the frame rate this card produces at 1080p. That gap only grows with anything newer. So the practical question for most 1660 Super owners isn't 'will my CPU choke this card': it's whether the card itself, or your RAM, or your storage, is the actual limiter in a given game.
There are edge cases: a genuinely ancient dual-core or a laptop chip throttling under load can still choke any GPU. But for a normal desktop build from the last several CPU generations, the 1660 Super runs into its own wall long before a processor becomes the story.
Which CPUs bottleneck the GTX 1660 Super?
The table below shows how CPUs stack up next to the GTX 1660 Super's 1080p frame ceiling. Notice the pattern: every listed chip clears it, which is the whole point of pairing a budget GPU with almost anything reasonably current.

Does the GTX 1660 Super bottleneck at 1080p, 1440p or 4K?
A CPU bottleneck on the GTX 1660 Super is almost entirely a 1080p problem. Frames come fast at that resolution, so a slow processor runs out of headroom first and the card sits waiting, average around 68 FPS in GPU-bound games, less in CPU-heavy ones if the chip can't keep up.
Move to 1440p and the GTX 1660 Super works harder per frame (about 46 FPS), so the same CPU has an easier job and most of the bottleneck disappears. At 4K the card is the limit in nearly every game, and the CPU barely matters.
How to tell if your CPU is bottlenecking the GTX 1660 Super
- GPU usage stays pinned near 99% during gameplay. The card is working at its limit, which points at the GPU, not the processor, as the ceiling.
- Lowering settings barely moves your frame rate, because the card was already the constraint and easing its workload doesn't free up more frames from elsewhere.
- Frame rate stays steady in both busy, NPC-heavy scenes and quiet ones. A real CPU limit would sag specifically in the crowded moments, and that pattern isn't showing up.
How to fix a CPU bottleneck on the GTX 1660 Super
Two fixes: raise the resolution or graphics settings so the card does more work per frame, or move up to one of the green CPUs above. For the full ranked pairing guide and exact combos, use the tools below.
GTX 1660 Super bottleneck: your questions answered
No. Pair it with any current mid-range chip and the card is the limiting factor by a wide margin. A modern CPU has far more headroom than this GPU can ever use, so nothing about that pairing holds the card back.
You don't need to reach far. A Ryzen 5 5600 or a Core i5-12400F already gives this card everything it can use, and stepping up to something pricier just adds cost without adding frames on this GPU. Save the budget for the next GPU upgrade instead.
Genuinely old quad-cores (think first-generation Core i5 or i7 chips, or entry APUs) can occasionally hold back a card like this in newer, CPU-heavy titles, though it's less common than people expect since the 1660 Super's own ceiling is modest. If you're running one of those older chips, the free checker above will tell you exactly where you land using your specific pairing.
More than enough. The 3600 is the weakest chip in our current comparison set and it still clears the frame rate this card produces at 1080p without trouble. You'd need something considerably older to actually feel a limit.
It needs a reasonable one, not a good one in the enthusiast sense. Anything from the last several generations of Ryzen 5 or Core i5 (even budget SKUs) supplies more frames than this card can render at 1080p. Spending extra on the CPU side doesn't buy you anything here.
Roughly 68 FPS on average across demanding AAA titles at 1080p with typical settings, dropping to around 46 FPS at 1440p where the card starts to strain. Lighter and older games run well past those numbers.
The CPU won't be your problem at 1440p. The card will. Average frame rate drops to around 46 FPS in demanding games at that resolution simply because the GPU itself is working harder, not because a processor is withholding frames.
Check GPU usage while playing. If it's sitting near 99%, the card is the limit and your CPU is not the story. A CPU bottleneck would show up as usage dropping well below that while frame rate stays flat, which is rare on this pairing unless the chip is quite old.
For almost everyone, the GPU is the better upgrade target. Since most current and recent CPUs already feed this card more frames than it can produce, swapping the processor first typically buys you nothing measurable in-game.
For 1080p at moderate settings, yes. It's dated, but it still clears the numbers above in most titles. Where it struggles is newer, more demanding releases and ray tracing, and that's a GPU limitation, not something a CPU swap will fix.
