Performance will be significantly better. Power consumption will be way way way better. Integrated graphics (Intel) will be extremely better than 2019. Just check the benchmarks. Your drivers will still be supported for years by all vendors (even on Linux that matters somewhat: although everything is always supported, vendors tend to put most of their resources on the newer stuff).

Also, you'll have USB-C ports, the newer hard drive standards, memory, latest wifi protocols (I don't know if there is one, to be honest), etc etc.
