A bottleneck is a limiting factor.

A system only works as well as it’s worst part. In a bottle, the narrowest part is the neck so liquid can only flow out at the speed the neck will allow.

In your case, even though your GPU is good enough to deliver much higher performance, your cpu is not. The performance can only be as good as the cpu can handle despite your GPU being capable of more. The cpu is the bottleneck limiting the flow of performance.
