So? Checked lots of retailers/vendors in China, they all told me the same story - no Epyc in stock, but Intel's latest servers/processors can be shipped in hours. In fact, I ordered several Xeon processors last Sunday and they showed up on my doorstep yesterday. For Epyc, I need to pay the full price and wait for 4 weeks to get anything with the Epyc logo on it. when searching the keyword Xeon on taobao.com, I got over 100 pages of results, from $130 second hand E5-2670 to stupidly expensive Platinum 8180. Searching on Epyc gave me a blank page with 1 and only 1 seller promising to ship in 4 weeks. AMD is not ready for such a battle with Intel and I am not going to waste my time on such half baked products which is not even really available to consumers months after its paper release. posted from my new dual Xeon based workstation.

That's because Epyc is a new name, while Xeon is up to what, E7? I bet you're not getting so many hits for the latest Kaby Lake Xeons. And you'd get better results looking for comparable Opterons for older systems.

  No, if I search for "Platinum 8180", the top model from the latest Xeon families released roughly at the same time as Epyc, I have a full page of results covering dozens of different vendors. Most of them can ship within hours, e.g. the one I used 2 days ago shipped within 30 minutes. As comparison, if I search for Epyc, I can see 1 and only 1 vendor who is asking for the full price to be paid up front for a 4 weeks delivery.

    Okay, you're getting downvotes for no reason. So Imma +1 you. I don't think you're very wrong. With that said, you're still "somewhat wrong", but not in a way that deserves downvotes IMO. > No, if I search for "Platinum 8180", the top model from the latest Xeon families released roughly at the same time as Epyc Xeon Platinum 8180 is Skylake, which is -2 architectures behind. There's Kaby Lake and Coffee Lake ahead of the Skylake architectures. Granted, Intel releases servers at -1 architecture compared to consumers, but... yeah. In any case, I'm not aware of any Kaby Lake Xeons available, let alone Coffee Lake.

      Skylake S/SP is the current architecture which officially launched this year. Kaby Lake will most likely won’t appear in Xeons and the next refresh will be either Coffelake or Canonlake. This time around there is also a big difference between Skylake S/SP and Skylake this isn’t Haswell where the only difference was the corecount. Skylake S/SP has a different FPU structure AVX512 and SIMD CD support as well as a new core to core fabric interconnect and a few other changes.

        Those don't compete with AMD EPYC or Xeon Scalable Processors, but are low end server processors and workstation quad core parts. Intel's marketing, naturally, makes knowing what their current product lines are extremely confusing.

        cute! quad core sever processors

        These are effectively i3/i5s there is no Kaby Lak SP/X (well there is technicall X but these are 2-4 core CPUs which isn’t a traditional X class) and it’s not coming the 2018 refresh is Cascade Lake which is annoying since you’ll have Coffe, Canon and Cascade Lake all the the same time so I’m guessing it will be CFL, CNL and CSL not confusing at all. https://en.wikichip.org/wiki/intel/microarchitectures/cascade_lake https://en.wikichip.org/wiki/intel/microarchitectures/cascad...

  E7 Xeon is the old naming scheme. Xeons used to roughly follow E3 / E5 / E7 (just like i3 / i5 / i7 in the consumer brands). The latest Xeons naming scheme for Skylake or newer is Xeon Platinum / Xeon Gold / Xeon Silver.

    Thanks. I probably knew that at some point, but the x299 chipset was so crazy it just pushed that knowledge right out of my head.

You might have more luck looking for Threadripper. Epyc is aimed squarely at servers.

  Thanks but I have been running server processors at my home lab for almost 8 years now. ;)
