AMD Socket AM5 an LGA of 1,718 Pins with DDR5 and PCIe Gen 4

A reliable source with AMD and NVIDIA leaks, ExecutableFix has shared some interesting bits of early information on AMD's next-generation Socket AM5. Apparently this will be AMD's first mainstream-desktop socket that does away with pins on the processor package, shifting them to the motherboard, in a Land Grid Array (LGA) format. This won't be AMD's first client LGA, though, as it was the Quad FX platform from 2006, which used a pair of Socket F LGAs. Socket AM5 will have a pin-count of 1,718 pins, 18 more than Intel's upcoming Socket LGA1700, on which its 12th Gen Core "Alder Lake-S" is expected to be based.

AMD will give the I/O of its client desktop platform a major update, with the introduction of DDR5 memory. Socket AM5 processors are expected to feature a dual-channel DDR5 memory interface. With Intel "Alder Lake-S" implementing DDR5, too, you now know why every major memory manufacturer is unveiling their first DDR5 U-DIMM product development. Interestingly, the PCI-Express interface on Socket AM5 will remain PCI-Express 4.0, even though PCI-Express 5.0 is being rumored for "Alder Lake-S." The switch to PCI-Express 5.0 may not be significant from a graphics cards perspective immediately, but paves the way for next-gen M.2 NVMe SSDs with double the transfer-rates of current drives that use PCI-Express 4.0. AMD is developing the new 600-series chipset to do with its next-generation Socket AM5 processors.

Musselshe got upset people gave him facts and told him he was wrong, inboxed me some harassment and left the forum. He gone.
He (or she) was (half) right on one (minor) point: AMD ripped off BMW's naming scheme only after they saw Intel doing the same.

Harassing a moderator? Jese, that's a rather dumb thing to do.

He came off as a conspiracy nut, with some long winded stories about how AMD are only good because they poached one intel employee, who then left back for intel - none of which is actually relevant to the products for purchase, it's only backstory.

AMD have rarely had the performance lead (but it has happend a few times), but they're always aiming to be the first and most creative when it comes to tech. x86-64, first to 1GHz, first IMC...
Not all their tech ideas work out, but holy shit they innovate and always have

Yeah, unlike that other company that was taking a five-year-long snooze and only woke up because AMD came along and lit a fire under their collective asses.

Don't forget Infinity Fabric and chiplet CPU/GPU design!
I can just imagine some engineer at AMD going "Hey, what if we chopped up the CPU die into smaller pieces?

And yeah, Intel basically pulled a Tortoise and the Hare. Outsprinted AMD early, then went to take a nap for 7 years and AMD passed them.

What I really hope for is a CPU retention mechanism similar to Intel that won't allow the CPU to come off the socket still glued to the heatsink, give me that and I'll be happy. That only happened to me once after using crappy paste, but I've seen it happen to others.

AthloniteIf AMD are going LGA for mainstream desktop CPU's I'll be down with that if they use an installation style like that of Threadripper
That would be the best socket to date, i did drop my 6700k in the socket once lucky for me it was 1 or 2 pins fixed them with a needle, that will sure ease the removal and install.

jesdalsHaveing gen 4 drives my self - I do find it doubtfull that 14.000MB/sek transfer rate desktop parts is high demand any time soon - 4tb drives to a affordable price though
Sustained speed is pretty much useless, small write/reads are whats important

In real world usage my WD SN850 performs idential on my Intel (signature rig) and my AMD rig which is B550 + 5600X, 6700XT

So PCIe 5.0 is going to be pretty pointless for consumer market, PCIe 4.0 x16 does not even improve GPU performance compared to 3.0 x16

PCI-E 5.0 is gunna be like 4.0, its biggest advantage is on devices using 1x slots

a 5.0 1x USB 4.0 controller is gunna work a lot better than on 1x 3.0

Caring1I hope the pins are sturdier than Intel's.
Intel has been using LGA since Pentium 4 days, no pins

Wow, no pins in the socket, why didn't I notice that /s
