If this morning we talked about the news of Sapphire Rapids as such and the claims of Intel with this new platform, which is late yes, but at the same time will be a breath of fresh air for the sector, well, now we have to talk about the strange arrangement that Intel has given to a certain version of its processors. Sapphire Rapids will have the privilege of being the architecture that has in its design the first processor with “at“, thus housing the aforesaid 64 GB of HBM2E in a very particular way.
But what do we mean by a processor with wings? Well, Intel’s concept is really interesting, but before we get to that, we have to hit a stick like socket, because there’s a lot of controversy.
Intel Sapphire Rapids, the processor with wings to fly over AMD

Or at least he will try, since the EPYC is not going to make it easy for him in fact. The chip layout that was shown is so characteristic and irreplaceable that honestly, although ugly, it is a work of technical art.
We are used to the typical Intel package for its Xeon where the sockets have taken on a rectangular shape given the proportions of the processors. Well the LGA-4677 socketthis monster that we saw at the time which is divided into two parts and has two central rows where Intel places the I/O voltage resistors, this same socket will house the two types of processors that we will see next.
As we can see, Intel has launched an extended PCB design where the two longer sides stick out vertically. two parts of the PCB, one of them with what appears to be the 64GB HBM2E chip applied vertically. As can be seen, the processor on the right has these wings, a note that has already been given by users and to its credit resistors are integrated, but only on one side of the PCB. Why is Intel doing this?

The aforementioned LGA-4677 socket has an advantage that the others don’t have, where for example its LGA-3647 sibling wouldn’t even have crossed its mind, and it’s nothing more than two separate holes to shelter these wings. If we look closely at the socket, what we will see is that its support is at the same height, millimetrically speaking, as the retention system and the pins of the processor.
It is possible that they differ by a few microns, since when the retention system exerts pressure on the CPU, it will lower its height by a thousandth thanks to the fact that the pins of the card give way. This distance that is lowered is just enough for both wings to rest on the retention system and with it the processor is leveled.
At the same time and as is logical, Intel has not included resistors on the contact face of the pins in said wings for this reason, so it is a rather particular and innovative design where it shows that the blue team is at the limit in terms of usable surface availability and as we have seen, it has to resort to these tricks to be able to compete with AMD. The question is whether he will succeed although he has two disadvantages.
