Ubuntu 21.04 Identifies RTX 3080 as RTX 3070

Question

I have windows 10 and Ubuntu 21.04 configured in Dual Boot. I have reached here after facing so many problems with Ubuntu 20.04, after which I followed this question to setup my current machine that is running Ubuntu 21.04 NVIDIA RTX 3080 GPU not working with Ubuntu 20.04, Kernel 5.8.0-50-generic

The current problem I am facing is that Ubuntu detects this GPU as RTX 3070 while in reality it is RTX 3080. I will be using this laptop for machine learning with TensorFlow, cuDNN, and many other libraries that are known for their troubles with mismatching versions and unforgiving compatibility matrices.

Below are some information that might be relevant

Laptop: Asus ROG Zephyrus G15

Firmware Version GA503QS.405

Graphics card:

• Nvidia Geforce RTX 3080 laptop GPU (confirmed through MyAsus tool, windows task manager, Nvidia control Panel, and BIOS)
• AMD Radeon Graphics

I have the following disabled from the BIOS:

• Secure boot
• Fast Boot
• Asus Erp (Power Management utility that turns off the discrete GPU)
• Asus Armory Crate (Tool that switches between integrated GPU and the discrete GPU)

Interestingly both show RTX 3080, I will go ahead and ignore this until a related problem appear and will update accordingly.
