Irrelevant from a mass market perspective. That chip is still out of stock at Best Buy and the Amazon third party version is marked up 54% versus MSRP.

Incidentally the 11900k is also out of stock at many retailers, but it's so much cheaper. You can still buy a pre-binned version that clocks 5.1GHz; even with markup that costs 30% less than the aforementioned third party 5950x.

Availability and price matter. My take on AMD's heavy focus on the enterprise segment right now is that they have no choice. If your enterprise partners get faced with scarcity issues, they will lose faith in your supply chain. You can tell a retail customer to wait patiently for 6 months, and even an OEM that makes retail devices (eg Lenovo) may forgive some shortfalls as long as there's a substitute available, but Microsoft and Google aren't going to wait around in line like that.

Honestly the price/performance ratio there is pretty nice in the eyes of a Mac user like me, but I don't know what office is buying Alienware, and a bulk order would no doubt take longer to deliver. Those are the only machines popping up when you filter for AMD 5000 series on dell.com.

Considering that 5950x is AM4 compatible, folks who had bought a pre-built machine and want to upgrade are also part of the mass market. And I think you can't discredit the homebuilt PC crowd for a high-end desktop chip. The people who care enough to want this chip can probably figure out how to clip it into a motherboard and tighten a few screws and connectors here and there.
