LGA 4189 is the Latest Socket for Intel's Next Generation of Xeon CPUs
TE Connectivity, the maker of various kinds of connectivity solutions for computer systems, has released its latest iteration of the LGA socket for the next generation of Xeon Scalable CPUs. Being validated by Intel, the LGA 4189-4 and LGA 4189-5 are going to power the next generation of 10 nm Xeon CPUs, based on the Ice Lake architecture, and up to 56-core 2nd generation Xeon Scalable CPUs. While there are two models of the socket, TE Connectivity didn't reveal what the differences are between them. Socket P4 (LGA 4189-4) and P5 (LGA 4189-5) also feature exactly the same pin count, 0.9906 mm hex pitch and 2.7 mm SP height, so we can only speculate that the "4" or "5" in the revision is supposed to indicate details like higher power delivery capability or support for Ice Lake CPUs.
In addition to providing a new socket for Ice Lake, these sockets have support for PCI-Express Gen 4.0 and eight-channel memory (supported memory configurations are vendor dependent), meaning that we are getting two more memory channels than previous Xeon CPUs with a faster and newer PCIe standard.

They will need to drop same specifications to mainstream in one moment and because of that I will not pay AMD or Intel 10th Gen Processors.
Exactly as someone sad DDR5 during 2021. Intel I think confirm first 8 octa channel DDR4 in 2020 and DDR5 + PCI-E 5.0 in 2021.
I use some platform minimum 5 years because improvement in mean time is not worth of change everything.
It's much better to buy premium motherboard, premium CPU some good memory and keep longer.
My decision to wait longer on X99 looks like got confirmation much earlier then I thought. I thought during 2020 my decision will look very smart.
Off course it's important to Intel switch on new features even for Server because we are next.
Or they could do that but decide not to do... something like that.
That was some DDR3L...
So for some reason all Intel CPUs still support DDR3 for some reason, not sure about the Server parts.
Since the new socket has more pins then the previous one, i think it is a good bet, that we get a little more PCI-E lanes in addition to eight-channel memory support.

There are a very small number of motherboards that have both DDR3L and DDR4 DIMM slots, but Berfs1 is quite correct to say that support for one memory type over the other is the motherboard manufacturer's decision.
I don’t see why they need yet another new socket, personally, but that’s just how the business goes when you’re in an Intel environment. It works for them, I guess...
