Intel LGA-7529 Socket for "Sierra Forest" Xeon Processors Pictured
Intel's upcoming LGA-7529 socket designed for next-generation Xeon processors has been pictured, thanks to Yuuki_Ans and Hassan Mujtaba. According to the latest photos, we see the massive LGA-7529 socket with an astonishing 7,529 pins placed inside of a single socket. Made for Intel's upcoming "Birch Stream" platform, this socket is going to power Intel's next-generation "Sierra Forest" Xeon processors. With Sierra Forest representing a new way of thinking about Xeon processors, it also requires a special socket. Built on Intel 3 manufacturing process, these Xeon processors use only E-cores in their design to respond to AMD EPYC Bergamo with Zen4c.
The Intel Xeon roadmap will split in 2024, where Sierra Forest will populate dense and efficient cloud computing with E-cores, while its Granite Rapids sibling will power high-performance computing using P-cores. This interesting split will be followed by the new LGA-7529 socket pictured below, which is a step up from Intel's current LGA-4677 socket with 4677 pins used for Sapphire Rapids. With higher core densities and performance targets, the additional pins are likely to be mostly power/ground pins, while the smaller portion is picking up the additional I/O of the processor.

What a piece of tech, imagine handmaking the prototypes of that monster.
Let me know when I can grab mine Intel.
@AleksandarK you've switched between 7529 and 7592 in the article, but 7592 is correct. :)
New motherboard != upgrade.
That is called a rebuild.
Go take a lot at those Intel motherboards and start counting all the Intel chips that you can see and then the device drivers for Intel things like Nic and WIFI.
With ~80% of the market still blindly buying Intel how are they "missing" their goals? :rolleyes:
AMD may fumble from time to time though I've never seen them make an effort to screw over their customers.
Good luck finding a suitable case.
Here is a Xeon server board from a couple generations ago for example:
And here is an AMD Zen4 Epyc 1P board:
Servers are just VERY different these days than the typical PC most of us know. Far longer, and much more dense components. For anyone wondering what the heck an "OCP slot" or "EDSFF" is:

AMD screw their customer, not just Intel,
Intel today failure is not 2020 issue, it is 2015 failure that still hurting them to this days, it will be couple hard year for intel since the management before Bob Swan is really bad,
It's impressive size, but... so easy to destroy. I've said a while ago. Until Intel creates normal CPU mounting mechanism, I'll never go Xeon/HEDT. AMD TR/Epyc all the way here.
