PCIe Gen 4 vs Gen 3 Slots, Speeds

PCIe Gen 4 vs Gen 3 Slots, Speeds pcie 4 0 gpu in 3 0 slot PCIe slots feature the same pin layout and thus are forwards and backward-compatible However, a PCIe card slotted into a PCIe slot will pciex1 slot - GPU-1 : supports x16 , using x4 - GPU-2 (PCIE3 slot will run at a maximum of 4x PCI-E bandwidth In short

pciex1 slot Both PCIe and PCIe are backward and forward compatible Remember those high-speed components that use PCIe slots

pcie slot qrelease PCIe doubles the throughput rate per lane, giving users a transfer rate of up to 64GBs Why does this matter? The faster the throughput Yes, it'll be perfectly compatible with gen PCIE slot
