While there is no official version of TechPowerUp GPU-Z for Linux, the open-source community has developed several powerful alternatives that provide the same level of detailed hardware diagnostics and real-time monitoring.

It mimics the interface of GPU-Z, providing hardware lookup, sensor logging, and ReBAR detection.
