Documents show AMD AM5 will use DDR5 and PCI-E 4.0, not 5.0

According to new documents stolen during the attack on Gigabyte, the AM5 platform's I/O scheme has been published, revealing that 600 Series motherboards would use DDR5 memory and that PCI-E 4.0 will continue to be used, at least in Ryzen 7000s.

Specifically, it verifies that DDR5 memories will be supported in Dual Channel configuration, allowing a maximum of four RAM modules to be installed, as has been typical in “Mainstream” platforms for many years. There will be 16 lines dedicated to GPUs on the other side of the PCI-Express 4.0 lines coming from the CPU, 4 lines for an M.2 NVME SSD, and another 4 lines for a USB 4.0 controller that will also have a Displayport connection to allow it to work in alt-mode. There will also be a Displayport connection to allow it to work in alt-mode. Two video outputs, two USB 2.0 ports, one USB 3.2 Gen2 port, sound connections, and the connections for the BIOS are among the other connections that come out of the processor.

A number of PCI-E 4.0 lanes will be available on the chipset's side, which will be connected to the CPU by four PCI-E 4.0 lanes. These will be used for NVME ports, LAN, Wi-Fi modules, and other peripherals, as well as support for 10Gbps and 20Gbps USB 3.2, USB2 compatibility, and numerous SATA ports.

As a result, aside from support for DDR5 and USB4, there will be no significant changes in the I / O when compared to AM5. It will be interesting to observe when it transitions to PCI-E 5.0, which may not occur until the Ryzen 8000 or 9000 series processors are used in conjunction with the 700 or 800 Series motherboards.

So the AM555 meme is dead

RIP futureproof potential, this seems like it will have the same faith as 300 series chipset. Fastly becoming obsolete

actually great news for consumers and people who already have pcie 4.0 peripherals. this will help drive down the price for pcie 4.0 m.2 and ease the transition for AM4 users.

pcie 5.0 is great theoretically but in reality it's being used for marketing for Intel

Why is my chipset obsolete?
3000GB/s read and write is good enough for me on PCI 3 x4.
A 6900XT would also run just fine on PCI 3 x16.

I am limited to 3000 series CPUes unless I risk it with beta bios for 5000 series, but that is really the only thing bad about 370.

PCI 4 could deliver 6000GB/s or 2 3000GB/s disks.
The x16 GPU slot could also be parted up to 2 times x8 and deliver enough for 2 6000GB/s disks if needed.

Remember there is also Threadripper if the mainstream platform is too simple for you.

What future proof? People want a new cpu every 6 - 12 months here.
And they want to

In all of this pci express connectivity is the last of your worries for future proofing

intel got sloppy and amd got greedy
but you can't step into the same river twice

people like to throw in the word obsolete so that they think they're smart,without giving it much thought
what is obsolete:
4/4 cpus
gcn and kepler gpus

what is not:
3900x + 2080Ti system on a 970 Pro drive
