いったい何が違うのでしょうか・・・
PHP5.5自体はremi-php55レポジトリでインストールしたので、"php-opcache"の方がよさそうな気がします。（直感）
php-opcacheを yum install してみます。
vagrant@localhost:~% sudo yum install --enablerepo=remi,remi-php55 php-opcache

php-opcache は 5.5 にバンドルされた opcache を --enable-opcache=shared でビルドしたもの php-pecl-zendopcache は 5.4 のために pecl でビルドしたもの ... http://t.co/bgY0REeEV7

つまりPHP5.5.なら php-opcache を使えばよいということですね。
