What is GNA driver? Do I really need to instal this driver? Can someone explain please?

Hey emred,

The Intel GNA driver is for the Intel Gaussian & Neural Accelerator, it is a special purpose hardware on the chip that software can use to efficiently run some computations, namely neural network inference. This is similar to Apple's "neural engine" on their CPUs. GNA can run some simpler neural network models with perfect energy efficiency. You can install it tho. 

Also in my experience you have to enable GNA in the BIOS. If not enabled then the driver is not needed;

Advanced | Onboard Devices Configuration | GNA Device | Enabled
Somehow its not by default enabled on my TUF GAMING Z790-PLUS WIFI motherboard.

Hi guys. Windows Update Catalog shows two drivers 1.0.11405.42038 and 1.0.11406.42226. Can you tell me which one to install?
