But even there you see the problem. The Ryzen CPUs are only in their lower end budget systems, and the Threadrippers are only in their expensive high end systems. If you need a 'mid-level' system (like we buy where I work), with say around a dozen cores, an RTX 4090, and 128 GB of RAM, then you have to go with Intel even here. Their cheapest Threadripper computer with matching specs is literally $3000 more.

the ryzen 7/9 model is literally more expensive than every intel system they offer on that page?

and yes, threadripper is unfortunately quite expensive now, that's a decision AMD made back in 2019 with the 3000 series to go heavily upmarket on that. In most cases if you are a customer who is in the market for threadripper, you are better off just using epyc now, unless your highly-parallel workload also needs very high max clocks.
