Exposure shows that Intel's next-generation mainstream desktop processor, Comet Lake-S, will be replaced with a new LGA1200 interface, with a new 400 series motherboard, up to 10 cores and 20 threads, but still 14nm process and Skylake architecture.
In the server field, Intel's upcoming new generation of scalable and powerful Copper Lake is still the life of the 14nm Skylake family, but the interface will be replaced by the LGA3647 with the new LGA4189, and then the 10nm Ice Lake. This interface will continue.
Intel has never officially confirmed this, butConnector manufacturer TE Connectivity has made a “swine teammate”, announced its own LGA4189 socket, which has been certified by Intel and is now available to server motherboards and system manufacturers, including docking stations. Backboard, support frame, mounting clips, dust cover and other parts.
The process architecture is the same, why change the interface? May be similar to the desktop, in order to support more core, memory, more advanced PCIe.
Intel Xeon currently has a maximum of 28 cores and 56 threads, six channels of DDR4-3200 memory, and only supports 48 PCIe 3.0. The competing products are 64 core 128 threads, eight channels of DDR4-2666, and 128 PCIe 4.0.
The second generation expandable to the strong family, although there are 56 core 112 threads, but not to mention the dual Die integrated package, but also made a BGA way directly soldered on the motherboard, rather than a separate LGA socket, it is obviously temporary Hasty work.
Intel has previously announced that Copper Lake will achieve 56 core 112 threads and is an LGA standalone socket, which will be available in the first half of next year.
According to the information given by third-party agencies,Copper Lake will also introduce eight-channel memory, PCIe 4.0, and fully align with AMD Opteron.
The interface that is so necessary for so many changes, LGA4189 came into being, andAlso divided into two versions LGA4189-4, LGA4189-5, also known as Socket P4, Socket P5(The current LGA3647 is also known as Socket P).
The physical dimensions of the two interfaces (77.66× 56.6 mm), the pin layout and spacing, and the fixing method are exactly the same, except that the widths of the left and right partitions are different.
It's unclear why Intel is splitting the same interface into two versions. Perhaps one of them is specifically built for high-end models with more cores and more memory channels?
