Nope. USB4's bandwidth in symmetric mode is 80 Gbps. While PCIe 4.0 x16 is 32 GBps. The difference is big B, bytes vs little b, bits. USB4 is 80 Gbits per second or 10 GBytes per second. While PCIe 4.0 x16 is 32 GBytes per second.

USB4's bandwidth would be the equivalent of PCIe 2.0 x16 or PCIe 3.0 x8. Just slightly higher bandwidth that that.
