I think it is not quite fair to compare Dell Precision like laptops with any of the Apple laptop offerings. They are priced higher than average Mac laptop.
Apple reminds me of a Porsche - Porsche is not the fastest on quarter straight line drag, it doesn't have the most horsepowers, it doesn't have the most maximum speed, its' SUVs will be rivaled by any Wrangler or Toyota truck. BUT on average Porsche does the things like no one else: it is fastest on real race tracks due to handling, acceleration, braking and overall tuning. On top of that, this thing can be used as your daily driver. SUVs can go fast and also do some off-roading, while BMW could be faster but it is no offroader. Wrangler could be more offroader but it is not fast like Porsche SUVs.
Just don't expect miracle out of nowhere: M1 Mac's GPU is fast but only due to built-in encoders/decoders and all that extra stuff like faster ram, RISK and etc.
Apple is about making money. I highly doubt that they will offer something to please quadro T1000-T5000 owners, because they are minority.
