AMD confirmed Thursday that the next generation of Ryzen series desktop processors will use the Zen 3 architecture and are compatible with the X570 and B550 chipsets. Earlier, we learned this from the revised road map. For enthusiasts, as long as the motherboard manufacturer is able to provide a BIOS update, it can save the user an additional cost of acquiring a new motherboard.
AMD is understood to have officially released the X570 chipset last summer. The B550 chipset was unveiled with the newly released Ryzen 3 3100 and Ryzen 3300X processors.
The two CPUs are scheduled to go on sale on May 21 at $99/$120 (approximately 700 / 850 RMB). In addition, AMD says there are no plans to provide Zen 3 support for older chipsets.
The main reason is that even if AMD wants to introduce full support for each processor for each chipset, the capacity of the flash chip that stores bioS settings is limited.
Many manufacturers have increased the BIOS chip capacity from 16MB to 32MB, but the older motherboard was forced to cut off the previously “fancy” UEFI BIOS interface while upgrading the new processor.
But as many netizens have pointed out in their comments, the motherboard manufacturer may still be able to introduce extended support for Zen 3 for existing X470/B450 motherboards, in addition to AMD’s official statement.
For example, many X370 boards have previously received support for ryzen 3000 Series processors through BIOS updates, and even have the intention of retaining PCIe 4.0 support (for example, some B450 boards) that AMD wants to remove in individual versions of the BIOS.
