On the M3 the DCT is geared much tighter in 1st, 2nd, and 3rd gears. The manual is geared better for the top end as it can stay in third longer (up to 113 miles per hour) than the dual clutch which has to shift to fourth much earlier. That is why you see the manual creep up in third gear in the video below but it still can not overcome the DCT shift speed advantage despite having lower drivetrain losses.

Stock dual clutch E92 M3 takes on a stock E92 6-speed M3
This is a debate that ranges all the time on the forums. What is faster, DCT or manual? Well, the dual clutch simply does shift faster and we see time and time again that the manual can not match it. This is a constant on every platform with a dual clutch and manual option (Porsche PDK versus manual direct comparison was posted earlier this year). The more shifts involved the bigger the advantage a dual clutch will have.
