PC specs for LiveStreaming event.

Hi.

I would like to know how high specs I would need in a Laptop to Livestream a sports event to YouTube.

I want stream a wrestling competition running 3 cams on 3 mats, with one didicated Laptop and webcam per mat, 1080p 60fps.
The Laptop would need to handle a scoreboard with a clock and scorekeeping during the stream.
Eventually I want to use a Scoreboard connected to a network getting match info pushed to each mat, with info like contestant name, class, weight and match number.

I'm planning to put the scoreboard up in fullscreen on two external monitors, through HDMI and a splitter, controlled from a window on the Laptop through DisplayFusion, and also put the scoreboard in one corner of the livestream to YouTube.

Would a Dell Latitude 5420, running an i7 1185G7 suffice?
Will 16Gb of RAM be enough, or shuold I go for 32Gb?

I hope I have explained myself enough.
If more info is needed, please just ask and I will try to answer as best I can.

Business class, so that's good, and only 1080p60 not 4K, so that is good
Unknown (and potentially significant performance impact) - OS setup/optimization. I had a mobile Precision and corporate security software caused huge problems even with only single 1080p30 camera
*However*, that Latitude is a thin and light laptop, not desired for outright performance (like mobile Precisions) so thermal throttling is probably a decent threat.
What type of cameras? USB? be sure to test in advance to make sure you don't run into a USB Root hub bottleneck (may have to play with ports to spread load? or are you planning to use a Thunderbolt dock. Beware cheap USB docks (and even decent office models) with poor performance chips .. I recommend being prepared to test multiple dock options

And then there is your level of OBS Studio sophistication in avoiding unnecessary rescaling, understanding CPU impacts of certain filters, and CPU vs GPU encoding offload, level of compression on incoming video (and whether CPU or GPU doing decoding on that incoming video feeds)... so lots of unknowns with material performance impacts. And then whether thermal throttling will cause performance degradation

I know not a straight forward answer, but the answer is usually... it depends..
Hopefully others will comment on 3 video feeds of 1080p60 and whether 16RAM is sufficient. I'm assuming no discreet GPU with its own GPU vRAM, right? just the integrated Iris Xe Graphics?

sorry, I don't have experience that mobile CPU generation in this type of use case, so I can't be more specific. Good luck getting other responses. A fair warning,
  • your system could be overkill, or just be fine
  • OR based on your specific settings, might struggle. There are those with real OS and OBS Studio expertise that can really optimize both on under-powered hardware... who, *if* that Latitude 5420 struggled, could probably get it to work anyway (but such expertise is NOT common).
  • .. hard to know in advance without setting up everything desired, and testing

Good luck

Actually, there would be one laptop and one Streamplify Webcam per mat, so the question for 16Gb RAM vs 32Gb RAM is only for one stream, not 3 separate streams on one laptop.

And the laptops would be running stock Windows 11, no corporate control.
The thing is buying second hand refurbished corporate computers, it cuts a lot of the price vs buying brand new laptops in the same performance range, given it is a volunteer-based organization paying the price.

Anyhow, thanks for the answer, I take it that it's not impossible to do with the stated specs and hardware.
