Speed in fetching data in mysql laravel 5

i have a products table and select data with two queries below and time are executed, it is shown in debugbar (two queries is only changed field to select, structure to query is the same each other):

select * from `products` order by `created_at` desc limit 11   670μs shop

select * from `images` where `images`.`product_id` in ('3', '2', '1') 650μs shop

and another.

select `id`, `name`, `price`, `code` from `products` order by `created_at` desc limit 11  1.19ms shop

select * from `images` where `images`.`product_id` in ('3', '2', '1') 800μs shop

i have reloaded more times and time to load "select * " is always lessthan "Select id, name, price, code ". So, does query with select all field is always faster than select specific columns and why? Thanks!
