something to remember, the roblox’s servers are managing millions of users everyday and your average computer specs cant really handle that which is why they are going to be a bit more higher end, roblox isnt just dedicating all the resources towards 1 player, that would cause the servers to crash quicker than they currently do, instead roblox has to use a method “load balancing” to help their components handle the load that they have to take on, the average high end computer can barely run a playerbase of 200-400 players without issues and ping increases (the time it takes for your machine to ping another machine and get a response back), so for roblox to be running servers that can handle a playerbase over 1 million players without high ping issues or any of that really does show that the components used are fairly good, although they may be a bit outdated since they dont handle the load the greatest
