I've had a similar experience a few years ago. At the time, enthusiast Ryzen CPUs had just started outperforming Xeons that Dell and others were exclusively pushing. A sub thousand box edging out a ten thousand dollar workstation wasn't enough to move the needle until Threadripper workstations started to show up. Even then I wasn't able to push our IT to consider AMD as a serious replacement. Maybe that's partially why we still see ten Intel options for every AMD one.
