The new documents from the Gigabyte attack reveal that the AM5 platform’s I/O scheme has been published, and 600 Series motherboards will use DDR5 memory. Moreover, AMD will continue with PCI-E 4.0 at least for the Ryzen 7000s.
The document confirms that DDR5 memories will be supported in Dual Channel configuration. The configuration will allow up to RAM modules. The PCI-Express 4.0 lines coming out of the processor will be divided in the following manner, 16 lines for the GPUs, 4 for an M.2 NVME SSD, and another 4 USB 4.0 controllers, which will also feature a Displayport connection so that it can operate in alt-mode. The following connection will come from the processors: Two video outputs, two USB 2.0 ports, one USB 3.2 Gen2 port, sound connections.
Various PCI-E 4.0 lanes will be available on the chipset’s side. Four PCI-E 4.0 lanes will be connected to the CPU, which will be used for NVME ports, LAN, Wi-Fi modules, etc. They will also play a role in support for 10Gbps and 20Gbps speeds USB 3.2, USB2 compatibility.
Due to this, the I/0 will remain the same except for DDR5 and USB4 support. The transition to PCI-E 5.0 will be quite interesting, but it might not occur until Ryzen 8000 or 9000 series processors.
