Speed is absolutely unimportant, you could have opened Windows Explorer, sorted by name highlighted all instances and deleted them in the time it took you to post this message and wait for an answer to your off-topic question.

Open a Command prompt window, (cmd.exe), CD to your directory holding these files; then enter this:

For %A In (*.RAW) Do @If Not Exist "%~nA.jpg" Del "%A"
