I would really want to see a comparison with the previous generation Xeons, which do drop in price much faster than the consumer CPUs. I feel like higher-core ones will beat 1950X at tasks that multithread well. Examples: 18-core Xeon E5-2686 v4 = $450 (http://www.ebay.com/itm/172668300615 http://www.ebay.com/itm/172668300615) 18-core Xeon E5 2695 V4 ES = $610 (http://www.ebay.com/itm/272620269793 http://www.ebay.com/itm/272620269793) 20-core Xeon E5-2698 v4 ES = $745 (http://www.ebay.com/itm/282579817803 http://www.ebay.com/itm/282579817803) 22-core Xeon E5 2699 V4 ES = $920 (http://www.ebay.com/itm/201883329486 http://www.ebay.com/itm/201883329486) 24-core Xeon E7-8890 v4 ES = $999 (http://www.ebay.com/itm/352113502495 http://www.ebay.com/itm/352113502495)

In my experience the motherboards are a downside when considering a Xeon system - narrow range, expensive, often missing latest features, sub-optimal in an everyday desktop machine. OTOH there are dual socket options which threadripper doesn't have. There was an article on building a dual Xeon box using cheap second hand chips recently and I was seriously considering it until I saw the range and cost of dual socket boards.

  I read this article https://news.ycombinator.com/item?id=12249317 https://news.ycombinator.com/item?id=12249317 and had the same idea last year when I went to build a computer for the boy. It wasn't just that the price of the motherboard was a killer, navigating the subtle differences between similar server sockets and chips is hard. And used motherboards are not cheap and often proprietary. Then there's the fact that for a dual socket motherboard, a single chip is a bit economically inefficient...so a pair of chips starts to make sense. And then a bigger power supply. And still not good support for powerful graphics cards because...well, you know...it's a server motherboard. In the end, I got a bought the boy a used Dell Precision T7500 for less than I would have paid for an equivalent case and power supply. Sure only six Xeon cores and 12 threads. But a system with RAM, a windows license, a small hard disk and 12GB of RAM was half the price of the cheapest Threadripper...including shipping.

    But again that will lack the latest features that you will be getting with a Threadripper system, but I guess that might not matter to you. Bargains to be had I agree.

      With similar budgets, half a dozen used Precision hexacore Xeon boxes is within the realm of possibility. That's more cores and threads and memory bandwidth to throw at workloads that significantly benefit from multi-threading. Of course the premise is that most of the benefits from multi-threading come from software rather than hardware. From a systems perspective, there is a more robust pipeline of replacement parts for the used boxes relative to the latest retail Threadripper motherboards. More boxes means it is possible to stay up with a hardware failure (which is to say that scaling out instead of scaling up means a partial hardware failures versus total hardware failures). There's no free lunch of course. All those 1100w power supplies are going to equate to higher operating costs. And if first cost is no object then four or five Threadripper boxes will outperform the older hardware. Likewise if having the latest and greatest is part of the problem being solved. YMMV.

Most of those are engineering samples, no? Meaning they have no warranty. Aside from that they may suffer from various issues as these are basically test chips. I don't know if I would trust using them for anything important

The first 18 core Xeon is a defective CPU. I recently purchased a 12 Core Xeon E5 2670. It's pretty fast in Handbrake.

Your price links are all 'used', 'damaged', or 'refurbished'. Hardly a good comparison for brand new CPUs? I'm sure a used Threadripper is cheaper than new as well...
