That's going to run Cities Skylines 2 ~~really really well~~ as well as it can be run.

Does it actually scale well to that many cores? If so, that's quite impressive; most video game simulations of that kind benefits more from few fast cores since parallelizing simulations well is difficult

  • these big high-core systems do scale, really well, on the workloads they're intended for. not games, desktops, web/db servers, lightweight stuff like that. but scientific, engineering - simulations and the like, they fly! enough that the HPC world still tends to use dual-socket servers. maybe less so for AI, where at least in the past, you'd only need a few cores per hefty GPU - possibly K/V stuff is giving CPUs more to do...

      They scale very well for web and db servers as well. You just put lots of containers/VMs on a single server.

      AMD EPYC has a separate architecture specifically for such workloads. It's a bit weaker, runs at lower frequency and power and takes less silicon area. This way AMD can put more such cores on a single CPU (192 vs 128 for Zen 5c vs 5). So it's the other way round - web servers love high core count CPUs.

      Things like games, desktops, browsers, and such were designed for computers with a handful of cores, but the core count will only go up on these devices - a very pedestrian desktop these days has more than 8 cores.

      If you want to make software that’ll run well enough 10 years from now, you’d better start using computers from 10 years from now. A 256 core chip might be just that.
