LGA4677 Socket Spotted: Future Server Socket with PCIe 5.0 Support
by Anton Shilov on October 16, 2019 1:00 PM EST
TE Connectivity, a maker of various connectivity solutions in general and CPU sockets in particular, has revealed its roadmap describing future sockets for what looks like a range of future server processors. The roadmap reaffirms that Intel’s upcoming server CPUs will use LGA4189 sockets and indicates that some form of future CPU will use a larger LGA4677.
TE's LGA4677 socket will be made by the company starting from 2021, and is listed on the diagram as supporting PCIe 5.0. It is noteworthy that according to the manufacturer, LGA4677, LGA4189 and LGA3647 sockets will coexist on the market. This is likely due to long-standing contracts using existing sockets and requiring like-for-like replacements over the lifetime of the hardware.

Considering a significant increase in the number of pins featured by LGA4677 (compared to LGA4189 that will be used for Cooper Lake and Ice Lake server CPUs), it is logical to expect it to support processors with a higher TDP. Meanwhile, it is too early to make guesses about exact TDP levels. Alongside improvements in PCIe, we could also consider increases in memory controller counts as a strong indication of more pins.
No large server CPU company has formally confirmed existence of LGA4677 socket in its roadmap.

>a lot of good that does for us consumers :-)You say that like PCIe 4.0 is anything more than a marketing gimmick at the moment...

If the existing stuff is selling, you don't introduce something new. Max that $$$$$/££££brunis.dk - Thursday, October 17, 2019 - link
I'm glad Intel is letting their customers know what's available from AMD today.brunis.dk - Thursday, October 17, 2019 - link

No option, just suck it up. I promise no one will die.Kevin G - Thursday, October 17, 2019 - link
Following the cadence of LGA 3647 -> LGA 4189, I wouldn't expect any more memory channels. Rather the extra pins I fathom are for the changes from DDR4 -> DDR5, more PCIe lanes, more UPI lanes for additional sockets and of course, more power. In particular PCIe lanes as that is a clear short coming compared to AMD's platform.Rοb - Saturday, October 19, 2019 - link
LGA sockets with 8 to 10K pins are available: https://neoconix.com/custom-lga-sockets/ - Yet another reason to hold off on that build. ;)TE's brochure for their LGA 4189 socket says that the durability of the socket is 30 cycles. That will probably affect a few people whom test different CPUs on the same motherboard.
