I can confirm - I have a Precision 7670 in pretty much the top spec(i7-12850HX, 128GB ram, 3080Ti) and it's an absolute beast. It blows my previous HP Z5 workstation desktop out of the water, it improved my compilation times by half. Really made my work more productive thanks to the crazy spec.
You must be thinking of a different line of laptops - the Precision workstations are anything but thin. They are big and pretty heavy laptops with plenty of ports.
