Ideal Hardware Configuration

If you aren't transcoding or tone mapping, you are going to be disk IO or bandwidth limited before anything.

4K isn't the problem. It's tone mapping HDR. Because of how computationally expensive tone mapping is compared to just transcoding, the suggested setup is to have 4K HDR content in a separate library and pre-transcode and tone map your 4K HDR to 1080P SDR to use in your main library. If your setup supports 4K HDR, the content is there and no transcoding or tone mapping is necessary. If a user's setup doesn't support 4K HDR, having the 4K content in a separate library prevents a user from accidentally forgetting to switch which version they are watching.

In terms of just transcoding, the RTX 5000 should easily support 7 users. You MIGHT be able to support 7 tone mapped streams as well, if you don't want to pre-transcode and tone map your 4K library. The Intel Arc A380 can do 5 and it is my understanding that the 6GB of memory is the limitation. So having 16GB on your card should enable more tone mapped transcodes.
