Do you have an option called "use multi-thread" or "use multiple cores" (I'm not sure right now) activated on pcsx2? Because I think that option increases performance a lot. I remember reading somewhere it's recomended to activate that option if your cpu has more than 2 cores or threads.
I used pcsx2 on a core 2 duo E7500 for a period of time and it ran smooth enough for me on not very demanding games (only got slight slowdowns on Tales of the Abyss, for instance). But the E7500 had only 2 cores and no hyperthreading, so I didn't bother with that option.
Intel has better single-core performance, so of course it runs better, more cores != better performance. I dont think any emulators uses more than one-two cpu cores anyway. I had amd fx-6300 cpu for many years which is just little better than what Googie has, but it still struggled with dolphin and pcsx2, although this was many years ago when I tried to emulate them and I dont have that cpu/system anymore. I just moved to playing with burned discs on real hardware/softmodded wii instead since pcsx2 especially has/had issues with many games anyway.
These days I have ryzen 5 3600 cpu which can emulate both of them in widescreen and in 1440p - 4k depending on the game.
What I'm seeing as your biggest problem is your GPU: The Radeon in that particular APU is about as fast as a GeForce GT 710, which is a *really* slow video card by today's standards. Unless you're running the Software video renderer that's going to hurt, especially if you're upping the internal resolution/etc.
Better GPU doesn't help that much, when the CPU is the real bottleneck here. my old PC had fx-6300 with nvidia gt 440, and when I upgraded to gtx 660 and it didn't do anything for the emulator performance.
