Not as such, but larger caches are slower (due to the speed of light) which can reduce performance. A few apps have seen performance regressions on Tiger Lake.

Wouldn't it be more accurate to say due to gate delay because of an additional level in (de)muxing?

I assumed the slowdown is due to wire delay (a larger cache has longer wires) not gate delay but I could be wrong.

Cache access times are measured in nanoseconds. Light nanosecond ((c) Grace Hopper) is ~30cm
