Wrapping up just a bit ago was AMD’s annual Computex press conference. AMD brings their A-game to Computex, and for a good reason: as a PC focused show, it gives them great exposure, but it also allows them to promote their OEM relationships, the latter of which are crucial to AMD’s survival as the CPU underdog. Computex in turn isn’t a venue for deep technical announcements, but it’s a good place to get clarity on AMD’s CPU roadmap.

Starting things off then, let’s talk about ThreadRipper. AMD’s previously announced many-core CPU for the high-end PC desktop and workstation market was first announced at Financial Analyst Day a few weeks back. AMD is now in the process of slowly releasing information about the chip to build up interest ahead of its launch – which, before you ask, hasn’t been set yet and is still “this summer”.

At today’s press conference, AMD has confirmed that the 16 core processor will for most purposes be half of an Epyc processor. This means that the two die MCM chip will feature 4 DDR4 channels and a whopping 64 lanes of PCIe, with all 64 lanes being enabled for all ThreadRipper SKUs. This will be broken up into 60+4: 60 lanes directly from the CPU for feeding PCIe and M.2 slots, and then another 4 lanes going to the chipset (with an undisclosed number of lanes then coming off of it) to drive basic I/O, USB, and other features. AMD seems to be particularly relishing the point on PCIe lanes in light of the yesterday’s Intel HEDT announcement, which maxes out at 44 lanes and no chip below $1000 actually has all of them enabled.

The launch chipset for ThreadRipper will be the X399 chipset (ed: at this point AMD and Intel are literally trying to one-up each other). No details have been released on it thus far, so we’ll have to see what AMD has up their sleeve. But coming so close to the Ryzen launch, it doesn’t sound like it’ll be radically different. Otherwise we’re hoping to grab some pictures of X399 boards at the show today, as those should be on display. The ThreadRipper/Epyc socket in particular should be interesting; the chip is nothing short of massive, and in the one photo AMD has released so far of an Epyc motherboard, the socket looks equally huge.

Finally, not to be outdone, AMD’s 32 core & 128 PCIe lane Epyc CPU for servers has also received some news of its own. AMD’s first promising product in the server space in nearly half a decade will be launching on June 20th.

    That is one PHAT, sorry i mean EPYC processor! Reply

    Can someone confirm the tdp of 16core EpIc processor and if an matx motherboard will be manufactured ? (Because that cpu is huge) :) Reply

    The TDP has not been announced. As for mATX boards, we'll be crawling the Computex showfloor to see what has been announced. Reply

    TDW is ~155w for the 16c/32t part. roughly 75w per MCM Reply

    Ryan, quick question since I can't find any previous reporting on this topic. Why is this getting coverage 2 weeks after being announced?

    Arstechnica covered this on 17th of May. Did Anandtech also report and I missed it?

    Not only that but being such a big product (both literally and figuratively) i thought it deserved a spot on Anandtech's home page as well? Pretty poor form IMO. Reply

    Since this is a server chip, I highly doubt we will see mATX boards. We may not even see ATX boards, as these will mostly be used in workstations/servers. Reply

    4 DIMM slots, 2 PCIE slots.
    Yes it's doable since the boards don't need a Southbridge chipset/hub for peripherals.

    That would have been a better name than Epyc.
    The term "epic" is just annoying, AMD should have checked urbandictionary before going with Epyc.

    I agree... but on the other hand, "Threadripper" is amazing. Reply
