Question, what was the model of your old machine's processor and what's the new one?  Depending on how old your old machine is, effective processor speed might be much higher on the new one even though the nominal numbers might look comparable.  Processors topped out at about 3-4 GHz a decade ago and for power consumption/heat reasons have not increased clock speed at all.  The efficiency of these processors per cycle has increased quite a bit though, and this is not to mention newer stuff has more cores per processor usually and depending on which machine you went with, each core may be able to do hyperthreading (AMD Ryzen, Intel i7), effectively turning each core into two.  Most software doesn't take full advantage of the parallel processing that these provide, but if you're a multitasker, with lots of RAM consumption, running half a dozen or more programs at once, or tons of browser tabs open, it helps out a ton because it keeps processor resources waiting in the wings for each individual process to take advantage of.  Long story short, the new stuff is much better in spite of the fact that they look similar on paper.
