The High Bandwidth NDI codec will operate on the CPU.
The NDI-HX codec will (typically) operate on the GPU.
Six NDI sources shouldn't be a problem for most current CPUs to handle. There is an NDI Benchmark tool included with the NDI SDK that will give you a performance test on how many 1080p60 High Bandwidth NDI channels a computer can handle. This tool doesn't account for any overhead, so I'd say that you want double to triple the number that you plan to use. For 6 channel NDI workflow, you want the computer to report back at least 12 to 18 channels.
My HP Z4 workstation can handle 78 NDI channels.
