Eles não são iguais. O vimrc é o arquivo que você edita para mudar o comportamento do vim. É um arquivo de configuração.
O viminfo é como um cache, para armazenar persistentemente buffers de corte e outras coisas.
A partir dos documentos ( :help viminfo
):
The viminfo file is used to store:
- The command line history.
- The search string history.
- The input-line history.
- Contents of non-empty registers.
- Marks for several files.
- File marks, pointing to locations in files.
- Last search/substitute pattern (for 'n' and '&').
- The buffer list.
- Global variables.
Em outras palavras, o Vim escreve esse arquivo, não você.
Aqui está um exemplo um (minha versão modificada).
