Like I said, depends on perspective. There's programs that for some reason do better on Intel than amd, and vice versa. Autocad likes Intel. So amount of amd cores won't change that. To someone making the money some of these Autocad users make, going Intel is a no brainer and the added expense is made up for in time saved over a period of time. When time is money, faster = cheaper overall. When I retrofitted Cracker Barrel corporate offices, half the pc's were amd, the other half Intel, but they were all the same per department. Except for the web design who used Mac. This was done to apply specific strengths of the pc to the needs of the user. If you only saved 1 minute of time for a single user doing a project, doesn't seem like a lot. Do that for 100 ppl in the department and that changes the game, overall.
Perspective. Ya'll are basing the initial outlay, even including the cooling and mobo, vrs 2 individual prices. Not taking into consideration the possible/probable differences the platform will create over the 2-5 years of use.
Yes a 6cyl truck is quite cheaper than an 8cyl diesel. But I tow a camper and live in the mountains. Diesel = better overall, despite being far more expensive initially.
