I have a 2013 rMBP in this state now with a bad battery. It strangely alternates between "Replace Now" and "Service Battery" [1] depending on the day, but I do think performance is degraded.
It seems less significant but still noticeable when connected to power than on battery, even when the battery is full charged. IIRC my battery is around 50% design capacity with 1000–1500 cycles.
It would be nice to be able to definitively tell if macOS is underclocking or something.
