Oh yeah definitely, the 8-series was a fairly substantial leap over the 7 and not one I've really seen replicated at Intel's end yet. To be quite honest, the Ryzen 7 I upgraded to runs rings around my 8400, but given the price of Intel CPUs seemed to jump when the almost identical 9400 was released, it was quite a while before you could get a deal as good as I had from my 8400 three years ago (where does the time go?) I don't have any real benches to compare the CPUs with other than handbrake video encodes, which I've run on many of my machines, mostly for processing dashcam footage and the likes. The 7600 in my main PC would process at about 0.9x realtime, the 8400 in the LAN PC about 1.5x realtime, and the 3700X about 3x. Games-wise there was noticeable difference between the 7600 and 3700X as well, but as I've not run the 8400 in tandem with a capable GPU it's not easy to say how that would compare. Probably quite well.
