AMD Ryzen 3000 (Zen 2) Block Diagram Reveals 24 PCIe 4.0 Lanes

Earlier this week, a BIOS update for Gigabyte Motherboards confirmed PCIe 4.0 support with the upcoming Ryzen 3000 series. An official slide depicting an AMD Zen 2 block diagram with the Ryzen 3000 series and the X570 chipset was recently leaked. With the X570 being AMD’s in-house designed AM4 chipset, the AMD Zen 2 block diagram will provide a new PCIe 4.0 bus as well.

The AM4 “Valhalla” platform provides 24 PCIe 4.0 channels, 16 of which are assigned to the PEG, which can be transferred via external switches while the drive is configured as a single x16 or two x8 slots. In addition this, there are 4 channels assigned to one M.2 NVMe slot and the remaining 4 channels are used as a chip group bus.

The X570 chipset can handle USB 3.1 Gen 2 connectivity, Wi-Fi, Bluetooth, and SATA 6 Gb/s. The PCIe 4.0 standard can support up to 16 GT/s transfer speeds. The bandwidth will vary, but the highest recorded PCIe 4.0 x16 has a bandwidth of approximately 31.5 GB/s, almost twice the PCIe 3.0 x16 (15.75 GB/s)

AMD is expected to announce the “Matisse” CPUs at Computex ’19 and are officially scheduled for launch in July. Following Gigabyte, other manufacturers are also expected to unveil their X570 variants on this Tuesday.

I've damaged way too many processors than I'd like to admit. Music and Sim Racing keep me sane; that is until I get a strange itch to tinker with stuff again.
