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.

Not a single bent pin or any CPU related damage, when I'm about to remove the cooler for whatever reason I just let some CPU stress run for 5-10 mins like Aida64 or similar and let it heat up before turning off the PC.
After that I give the cooler a gentle twist and it never got stuck nor damaged anything, heck I'm far from an expert and even I can manage this so idk why this is always brought up as an AMD issue or an issue in general.:confused:
To be honest I'm more concerned about Mobo socket pins than having them on the CPU but thats just me I guess.
This is coming from someone who ruined a 1TB NVMe M2 SSD with an aftermarket heatsink install+removal, yet I never had issues with CPU pins.:laugh:
also the heatsink problem isn't an issue if you have half a brain and know to stress test CPU for 5 mins & then twist the cooler before taking it off...
Driver issues? I've never had a driver issue in 10+ years, so IDK why this is always brought up as an AMD issue or issue in general.
Antivirus? I've never had an infection in 10+ years, so IDK why this is always brought up as an end user problem or a problem in general.
I could go on. You've never had an issue? Congratulations, doesnt mean a problem doesnt exist. A simple look at forums over the last 10+ years would show that a LOT of people have issues with AMD CPUs sticking to heatsinks and getting pulled out of motherboards, bending pins in the process. Multiple tech youtubers like Linux have put out videos on the subject over the years. It happens, it is an implementation issue with PGA sockets, used to happen on laptop CPUs too, which were all PGA and had a nasty habit of doing the exact same thing.Hard paste is the cause, but there is a solution. Intel figured that out with the LGA retention bracket, they had the same issue on socket 370/423/478. Third party brackets for some coolers on socket AM4 have a retention bracket that fixes the issue. Whether due to lack of care, cost, or not wanting to break backwards compatibility with previous coolers, AMD's PGA sockets have never fixed this problem, while thanks to the retention bracket I've never had a modern intel desktop CPU stick to a heatsink no matter how hardened the paste was. I look forward to AM5 fixing this issue.
Sure I can see this being a problem if you wan't to replace cooler/CPU in a system that wont boot up but at that point you have bigger issues to worry about anyway.
Edit:
Forgot to mention, you could to the same search about ppl who bent pins/ruined their Mobo socket pins, I can see such mobos on the second hand market every now and then.
Its all the same, both designs have its problems and at the end of the day its mainly user end error/fault.
This isn't Android where the OS is shit and you need 4 cores constantly working on its background tasks, not even Windows is that bloated.
that's amd seems your computer would not actually exist right now if amd did not (:

YES It doesn't mean there isn't a problem, no denying that but since I own both and have so for years now I've had way less trouble from AMD's current design (PGA).
The thing about cooler and CPUs coming out together I've ran into myself many times over and I can tell you, most of those damaging CPU pins are STILL twisting the cooler as they remove it. The suggestion is always to twist the cooler and many take that literally as what do to before AND while trying to separate them from each other or just to remove the chip from the socket.
And by doing that what do you think IS going to happen to the pins doing that as it comes out of the socket?
The correct way is simply to pull straightup and out of the socket, no bending of pins that way. By doing that you won't damage any pins on the chip and it doesn't hurt the board either.
Remove it now, separate them after it's out of the board.

Thicker TIMs along with the stock "Gum"/TIM are also contributors, thinner TIMs aren't nearly as bad about causing it.
I always remove the factory gum that comes on them and replace it with a good, thinner type TIM such as MX4 or NT-H1.

LGA is probrably going to make things worse overall.
The older sockets such as 775 are good and far more robust than the later 1151 socket for example.
The problem is the fitting all those pins in the socket, a socket of the same basic dimensions as what's been used for years so to pack these extra pins in you gotta make them thinner, which also means weaker and they are more prone to bend/break because of that.
If they change the physical dimensions of the socket allowing for thicker pins there would be far less trouble but ATM I don't see that happening, in fact as the numerical pin count go up in these sockets it's gonna get worse.
There is yet another thing that many don't seem to know about or have mentioned much if at all, that would be the pins themselves shifting around in the socket, because for some reason they get/are loose where they are fixed into the socket.
They don't get bent, they just move around to one side.
All it takes is for a single pin to shift to one side "Just enough" and it will start throwing codes, making one think the board is defective or they just broke a pin. I went through exactly that with my Z77 OCF when it was new, took forever to figure it out but when I did I fixed it and it works BUT it also still tends to do this.
Not everytime but annoying as hell to deal with it, that sometimes happens to my IX Apex board too and had it do just that the other day.
I know each socket type has advantages but from what I've dealt with up until now PGA is still better.
Will be good for Makers, them and us.
I hope.....
If it was INTEL as usual, we'd be on the third socket now since 1000 series, easily. For INTEL, boards and chipsets are part of the business plan. So, it's easy decision for them: invest R&D to keep the previous generation, or invest in marketing to sell the new generation?
I've lived on nForce 680i SLI Quadfather setup for a while years ago. AMD has used LGA CPU's since ages. The desktop segment was the only exception, not vice versa.
Personally I'm hoping for coolers that attach to the socket with screws.
