### Interkonektivity via SLI
sli becomes NVlink 

##### https://en.wikipedia.org/wiki/Scalable_Link_Interface
>SLI allows two, three, or four graphics processing units (GPUs) to share the workload when rendering real-time 3D computer graphics.

>Not all motherboards with multiple PCI-Express x16 slots support SLI.

>**High-Bandwidth Bridge or SLI HB Bridge** (650 MHz Pixel Clock and 2GB/s Bandwidth) – This is the fastest bridge and is sold exclusively by Nvidia. It’s recommended for monitors up to 5K and surround. SLI HB Bridges are only available in 2-way configurations.
