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.

LGAs "look" cooler though...
AthlonXp IPC>Thunderbird IPC>Pentium III IPC>Pentium 4 IPC
That could work. It will also help prevent idiots from trying to put a 12900K in an X670-E.They couldn't do that. They had promised that Zen 3 support AM4 and you can't change a socket midway through its life.
I also like PGA. The motherboards are hard to screw up and if you bend a pin or two just bend it back!
With Intel's LGA style the CPUs are practically invincible, but if you accidentally bend a pin in there, or drop something, etc., that socket's as good as dead.
Its pretty hard to bend a pin/start a warranty claim on something that cannot be bent.
Also people who say LGA is superior cause you can get more pins into the same space. Well you realise you have to dedicate more of those pins to power planes due to the thinner contact area meaning if you tried to push the same amount of current through an LGA pad as what is possible through a PGA pin you end up with pretty torched sockets.
that's big brain
I've never had a problem with pins bending. The only issue I had once is when I purchased a used AMD Athlon CPU way back and 2 pins weren't exactly perfectly straight. Yes the eBay seller lied and claimed no bent pins, unless it was a shipping situation that caused them to bend. So I gently pushed the pins back until they were straight. Then it went in like warm butter, umm sort of.Insecurity perhaps? These companies are major multi billion dollar entities, not sure why @voltage has to troll AMD, but even lie about it too in his posts? :nutkick:
Here is an analogy...
What we have:
What we could have:
I am surprised nobody came out with something like that metal housing around it 10-15+ years ago.
Kind of like if you took the bottom of an LGA CPU and made that both the socket and CPU contact. It would be sensitive to dust though...
Or maybe we could have something similar to how the Compute Module 4 (Raspberry Pi) connects to its daugherboard. CPU is on a PCB that hooks onto 2 slots similar to PCIe slots.
They already have it: eesemi.com/vfbga.htm
As small as 0.4mm pitch. 432 balls in 11x11 mm2 area. Which would give you 1718 balls easily in a 22x22 area. :rockout:
As for why more pins? well thats easy to answer. Both Intel and AMD will increase core counts in mainstream sockets. Hence the need to add more pins. Intel moves from 8c/16t to 8c/24t (likely even higher in the future) and AMD will likely go even further with 8 or 12 core CCD. If each chiplet contains two CCD's like it does now we will see 32c/64t models (4x8) with two chiplets or if CCD=Chiplet then we will see 24c/48t models (2x12).
FACT:
AMD was the first to introduce 64 bit capable chips and Intel coudn't for a long while, that is until they made a deal with.......
AMD to get the knowledge on how to do it.
So goes that BS theory out the window - AMD can and does innovate new technology.
I still remember wondering where all the 64 bit Intel chips were but there was exactly 0 around because they didn't exist with AMD having them listed all over the place and that went on for at least a full 6 months if not longer.
Of course Intel then ran off with the crown for awhile but since not only have they lost it but things have come out as fact along the way in what they did (Or didn't do) to get it - None of it to any benefit to their customers and that would include you.
Next time get your BS right so your post(s) won't turn into the latest running joke of the thread. :nutkick:
Non-bendable, though ... well, that's a lot to ask.
64Bit? AMD
Multi Core Consumer Processors? AMD
First CPU to 1Ghz? AMD
I cant see something like BGA ever working in a consumer environment due to tolerances. There is already enough issues with LGA sockets and mounting pressures with effectively spring loaded contact points giving you far more tolerance. Take that away and I doubt any lay person would be able to get something like a TR working with a BGA arrangement correctly without a ritual sacrifice to the tech gods every time they went for a remount or God forbid a CPU cooler remount.
Pogo pins definately look interesting but I wonder how hard it would be to design the traces from all those pins out from the socket to the rest of the mobo would look.
