    Could you comment the applicability of this processor or processor line to a workstation in a professional environment such as an engineering office using 2D CAD that relies primarily on single thread processing...

    This is Threadripper

    Expect the upcoming 3000 series to scale to 32 cores+ and 4Ghz+

    EPYC wouldn't be a good fit for that market, although EPYC Gen 2 should offer benefits over EPYC Gen 1 due to the improved IPC. But it is highly dependent on the software. EPYC would be overkill though, and Threadripper would likely be the better for that market, but I'm not sure if any OEM offers Threadripper workstations (especially with ECC support, and other features like we see them offer with Intel). Which is a shame, as I think Threadripper would likely do very well there (and ECC support should be easy, PCIe 4.0 would be great for SSDs).

    EPYC/TR is likely on the *cutting edge* of workstation/pro environments __ including 2D CAD and single-thread processing. This would include Zen3 and future* variants.

    In fact, AMD's chiplet design will likely lead to specialized *Field Programmable Gate Array* (FPGA) high-performance accelerators for computationally demanding operations in 2D/3D CAD. It's easy to envision EPYC/TR workstations in 8/16/24 core environments with an application accelerator, and a graphic 'SIMD engine array' chiplet.

    If you ever get a chance to ask questions:

    Will AMD ever target the workstation market with EPYC? Intel offers Xeons (UP) and vendors offer Micro ATX and Mini-ITX motherboards. I'd rather run an EPYC, but it seems AMD is only targeting the large data center market.
  • Awful - Wednesday, August 7, 2019 - link

    Isn't that Threadripper's target market rather than EPYC?
  • darkswordsman17 - Wednesday, August 7, 2019 - link

    That should be Threadripper's market, but AMD doesn't seem to have really pushed for it into workstations. Hopefully they will with Zen 2, as it should offer comparable advantages over Intel's stuff that EPYC offers over Intel's stuff in those markets.

    I can't wait for the threadripper release myself.
  • notashill - Wednesday, August 7, 2019 - link

    You can already buy EPYC ATX boards and Threadripper mATX boards, the socket is obviously never going to fit into an ITX board. Why would you want EPYC on a small motherboard that can't fit the extra memory channels and PCIe slots that are its entire selling point over TR?
  • jakky567 - Wednesday, August 7, 2019 - link

    Didn't it leak that 8 core chips exist?

    I'm not sure about the product lineup though.

    Epyc is destroying Xeon processors.
  • Elstar - Wednesday, August 7, 2019 - link

    I doubt they’ll cover this, but what does The NUMA setup look like to the OS? Does Rome scale to 4P?
  • looncraz - Wednesday, August 7, 2019 - link

    It's configurable, default is one NUMA node per socket.
  • darkswordsman17 - Wednesday, August 7, 2019 - link

    From what AMD has said, to the OS it looks like unified CPU, with the I/O die handling everything that would've caused NUMA issues previously. I am going to assume it doesn't. I think they'd need a new socket to scale beyond 2. I think its going to be one of the ways they'll tout scaling in the future, as they're not going to be able to keep doubling up the number of cores by cramming more in to each die. Also if they start releasing hybrid processing units (i.e. chips with CPU and GPU dice - not for graphics but for AI and machine learning), I think they'd want to be able to up the number of sockets they can support.
  • Kevin G - Wednesday, August 7, 2019 - link

    Each socket as four external Infinity Fabric links on Epyc. This was required for four die parts in the first generation. Now that all the coherency is handled via a single IO die, all four external links woudn't be necessary to minimize latencies between NUMA domains.

    Kind of odd but a triple socket system would likely hit the latency and bandwidth balance with the available topologies. This would provide up to 192 cores, 198 PCIe lanes and up to 12 TB of memory.

    A quad socket would not be optimal for a gamut of workloads due to the intersocket bandwidth restrictions. Latencies would be good though. Standard fare of 256 cores, 264 PCIe lanes and 16 TB of RAM.

    An 8 socket system would have to abandon the concept of each socket directly connected to each other and in an already bandwidth starved scenario, would be suboptimal. Though technically it would be feasible to build now.

    I hope EPYC ends up as good as it looks on paper. AMD needs to get some market share now. while they can.

    >AMD and VMware have been close partners

    That is strange, but also nice to know. Considering Patrick Gelsinger once said he *hate* AMD in one of his IDF, at least the bad blood didn't carry over from his Intel's day to VMware.
  • deltaFx2 - Wednesday, August 7, 2019 - link

    It's hardly personal. His job at VMWare is to make money for the company and shareholders. If AMD is the way to do it, he'll happily collaborate. His job at Intel was to make money for intel. And it must've been pretty tough for him during the Opteron era.

    AMD's virtualization extension support also was rather inconsistent earlier in its life as I remember it.

    No clocks mentioned?
  • abufrejoval - Wednesday, August 7, 2019 - link

    ah, just found 3.4 GHz...

    So my understanding of the SKU table is only core count and SP vs DP is differentiated.

    So are the clocks pretty linear across the line and TDP needs to scale or is TDP near constant and you get go chose if you want to turn heat into clocks or cores?

    Very little technical detail so far...
  • abufrejoval - Wednesday, August 7, 2019 - link

    stupid me, all in Johan's article...

    In this post, you are mentioning something new about technology and work. The way of explanation is too good. This shows the advancement in technology.

    CBD is ordinarily used to soothe a few side effects of uneasiness, including sleep deprivation, and a few investigations have demonstrated it to be viable in those cases.
