I don't think all 40 of those lanes are CPU powered, however. One of the big advantages of TR4 was the PCIe lanes you get without getting bottlenecked at the chipset. Unless there is some sort of AM4+ socket that includes more PCIe lanes, there will always be a place for TR4/HEDT for high-IO needs.The R9, in a much smaller package, with support for up to 16-cores and 40 PCIe 4.0 lanes
If this is true, then AMD really needs bump up the RAM support to quad-channel (and support high-speed low-latency 32GB & 64GB sticks of RAM) & then ASRock can give us an AMD version of the Little Monster...!I would like to think so too. I am all for a TR4-ITX board myself.
However, there are rumors swirling that the TR4 platform may be killed off altogether with the release of their new R9-series processors. Recently, AMD removed TR processors from their roadmap for this year but I guess it's always possible that it's been pushed back to 2020. Also, the gentleman that was head of the Threadripper division is no longer with AMD so it's anyone's guess if that position has been filled or axed. Either way, without a shred of TR news, that leaves the TR4 platform with a questionable future.
The R9, in a much smaller package, with support for up to 16-cores and 40 PCIe 4.0 lanes is likely more affordable for all partners to support as well. This means that board partners won't have to invest resources to support two independent processor platforms under AMD ...AND, it also provides a stellar upgrade path for Zen2/Zen2+(2019/2020, AM4) owners. If AMD decides to take this route, with a small hit from their TR4 audience, this would help to deliver a tremendous blow to Intel's highly-segregated processor lineup.
I believe AMD said the AM4 socket was solid to 2020, not thru 2020...Back to the topic at hand, if buying into AM4 finally gives us a path to upgrade all the way to AMD's HEDT R9-series processors, with nothing higher and not having to replace AM4 with TR4, the appeal of that already appealing platform just got a little better. I won't be surprised if AMD goes either direction but I also wouldn't be surprised if AM4's replacement socket (2021?) doesn't see a Threadripper-series as a result.
Anyway, if I can sqeeze any more information out of @ASRock System regarding their X570 ITX platform, I will be sure to share it.
would it do 40 lanes with just the current number of pins on the AM4 socket? o_oThe R9, in a much smaller package, with support for up to 16-cores and 40 PCIe 4.0 lanes is likely more affordable for all partners to support as well.
AM4 is not wired for more than 24 lanes, afaik. 20 for general use, 4 for the chipset (which acts as a hub/switch for more lanes).would it do 40 lanes with just the current number of pins on the AM4 socket? o_o
also that sounds bad for my decision making ,_, i definitely don't want to panic-buy an entire system for under $2k
AMD has another significant presence at Hot Chips this year. maybe the multidie EPYCs will be detailed by then. no word on an august/september date yet though ,_,At any rate, AMD's CEO already confirmed EPYC and Zen 2 are Q3 launches. With the NUMA issue being resolved with a common I/O hub, and chiplets basically zapping the scaling issues that brought about TR4 in the first place, it does seem like TR4 is going to be even more niche. What a shame, too, since the EPYC layout basically resolves most of the Threadripper problems.
