Gigabyte Leak confirms AMD B840 chipset details

Expect to see three new AMD/AM5 motherboard chipsets at Computex

Thanks to Videocardz, details for AMD’s upcoming AM5 motherboard chipsets have leaked. This leak comes from internal Gigabyte slides, revealing AMD X870E, X870, B850, and B840 motherboard chipsets. An earlier leak from Gigabyte has revealed AMD’s Ryzen 9 9950X CPU and other Zen 5 details.

For AMD’s X870E, X870, and B850 chipsets, PCIe 5.0 support is required at varying levels. With B840, only PCIe 4.0 support is required, and motherboards do not need to support CPU overclocking. Conversely, AMD B840 motherboards will only support memory overclocking.

Higher-end 800-series AM5 motherboards will support CPU overclocking and a PCIe 5.0 x16 lane (at a minimum). For X870 and X870E, support for one PCIe 5.0 SSD is required, as is support for USB4. X870E motherboards will feature two Prom21 (Promontory 21) chipsets. Consequently, these motherboards will support additional I/O capabilities.

On the low-end, AMD’s existing A620 motherboards will continue to act as AMD’s budget-oriented AM5 motherboard chipset. By maintaining this chipset, AMD hopes to drive down pricing with increased volume and further platform optimisation. As a result, PC builders should not expect to see new A820 series motherboards from AMD.
