But your comparison isn't fair. You let the regex do way much work than needed. There's no need to parse the entire line, and only assign if there are exactly four fields - you aren't doing that for the split cases either. Also, you only have one set of parens, yet you do four assignments. Picking a simpler regex, and doing just one assignment improves the speed with 50%! 
$a=$1 if $myvar =~ /^[^,]+,([^,]+)/

Still not as fast as the split, but it shows that proper Benchmarking is an art.
