My laptop is the Vostro 7590 with the i7-9750H and GTX 1650, I'm not sure if the same will happen with the XPS 9500. I could just disable those features every time I disconnect from the dock, but that's an annoying process.

Without C-State, SpeedStep and Speedshift, the laptop runs at its base clock constantly and consumes 3x the battery life while idling which is fine when it's connected to the dock, but not good when running on it's own battery. On the other hand, unless I have C-State disabled in BIOS, SpeedStep disabled in BIOS, and SpeedShift disabled in BIOS, I get constant annoying mouse, keyboard and audio stutters in addition to coil whine while connected to the dock. If WD19TB and WD19TBS are the same but without the audio out 3.5mm jack, I'd go with the WD19TB.
