The reason why X570 motherboard can sell at a high price is inseparable from advanced technical specifications, especially PCIe 4.0 is still the only one at present, which we have saved before.AMDIt is very generous on the platform of Ruilong 3000 and X570. It provides 44 PCIe 4.0 channels and 36 available channels. Tuhao is wayward.
X570 motherboard is expensive, many players can not help but expect more mainstream 500 Series chipsets - B550 and A520 can also support PCIe 4.0, but unfortunately these two chipsets support PCIe 4.0 is basically no use, from the supply chain explosion, these two chipsets will only be on PCIe 3.0, cut off PCIe 4.0 support.
But don't give up hope altogether.B550 and A520 chipsets do not have PCIe 4.0, which does not mean that B550/A520 motherboard is completely out of touch with PCIe 4.0, because AMD support for PCIe 4.0 is divided into two parts - 44 PCIe 4.0 channels, 24 from the Ruilong 3000 processor, and 16 from the X570 chipset itself.
In other words, there are 24 PCIe 4.0 channels in theory, 16 of which are for graphics cards, and 8 are flexible allocation. If the motherboard manufacturer is willing to do so, B550/A520 motherboard can also access PCIe 4.0.
Now the problem depends on the choice of the motherboard manufacturer. Considering that PCIe 4.0 still has certain requirements for the motherboard PCB, it will increase the cost. Whether the motherboard manufacturer gives the B550/A520 motherboard PCIe 4.0 or not will have to be analyzed in detail.
