PCIE 4.0 doubles the bandwidth ng PCIE 3.0. In real world scenario, it can support dual graphics card without splitting x16 lane into x8. Also NVME SSD uses x4 slot which benefits from the bandwidth capacity and lanes provided. Commonly kapag may NVME slot ka at may apat na SATA ports [0 1 2 3] kapag naglagay ka ng NVME SSD automatically disabled ang SATA 2 and 3 to compensate sa speed ng NVME slot dahil limited lang ang lanes na kaya ng motherboard sa PCIE 3.0. With PCIE 4.0, walang sacrifice na mangyayari. Hope makatulong.
