It depends on a few things. The car has three throttle sensitivity settings: normal, sport, and sport+; it also has six Drivelogic modes that alter the transmission shift speed and aggressiveness (when not in manual mode).
When everything is set to normal and the trans is in the middle D3 setting, it's probably 500-600rpm or so. If you have the settings turned up to be sporty, the engagement is quicker, maybe only 300-400rpm, though I think it also feels faster by the sharper throttle response.
tl;dr: "it depends"

My car has such a transmission. At low speeds, try to imagine someone trying to engage the clutch on a real manual at as low a speed as possible.
Yes, it is too jerky for some people's tastes, but I don't really care.

My Jetta TDI, DSG was able to creep slowly in first gear without problem. The first gear ratio was such that idle RPM resulted in something slower than walking speed. It was certainly perfect for creeping traffic jams. Anything slower than that required riding the brakes, like any vehicle.
The DSG would, if you wanted, slip the clutch to achieve an inching slow speed. Such as pulling into the garage and getting close to the wall with precision.
I'm sure there will be those here who worry this will prematurely wear out the clutches. This does not seem to be the case. I got stuck in as many traffic jams as anybody. And I regularly rode the brakes to park the car with precision. When the flywheel exploded at 70,000 miles, the mechanic that purchased the car said the clutches were still like new.
Notice the robust clutch pack!

The setup used by Eaton (under the names "Ultrashift", "Autoshift", and "Freightliner Smartshift") is dreadful. We have one (2011 Freightliner M2) at work, & I have driven it...and I named the truck! In honor of how it shifts, I call it "Lurch". It's horrible...it is NOT POSSIBLE to drive smoothly at low speeds. Backing a loaded truck into a dock is truly nerve-racking. If a driver was as bad with a standard shift as this thing is, he would NOT be hired! I'm honestly surprised it hasn't tossed a drive shaft yet.
