Question

Why is the PCIe link speed on the NVIDIA RTX PRO 6000 Blackwell Max-Q, 4500 GPU card downgraded to Gen1, even though the connection supports Gen5?

Answer

Because installing the latest driver has put the GPU in lower performance mode.

The GPU is capable of achieving PCIe Gen 5 speed only when operating under load conditions.
