Youll get more power consumption and heat but it'll be able to double your performance in many games.
Ive been able to get good FPS in CSGO and Fall Guys at 1080p using my 2nd hand Lenovo with its R7 3700U. Ive seen people playing GTA and Warzone with the same specs too!
Can it handle PS3 emulation?
No, and not for a while.

I forget if they have OpenGL 4.3 in them, but they're very underpowered. They can run things (LowSpecGamer does a lot of intergrated graphics stuff) but they aren't on the level as an actual GPU right now.
Edit: note that the MINIMUM is just that. When they say "will be unplayable" they mean it. Demon's Souls was able to "run" back in like 2013-2014 on a 7XX GTX GPU, but it'd get a frame-rate of like 10-20FPS from what I remember. PS3 emulation is "getting better," but you really need a good GPU/CPU combo.
I mean, you can run modern titles with some concessions (hell look up GPD Win videos), but emulation's general rule is "2x of the hardware being emulated's power" which Intel HD/whatever AMD simply isn't gonna cut the mustard on.

All current and recent support all modern OpenGL including 4.6. They also support Vulkan, as do RPCS3.
I will not bet on their performance because I do not know but I will be less skeptical, as GPU shaders are not an expensive part of emulation and do not adhere to linear relationship with relative power to the original machine. The PS3 also does not have a strong GPU regardless. The important part of the specification for these purposes are features which the emulator uses being present.
If you're looking to play PS3 games the cheapest way is still to buy a second hand PS3 and jailbreak it. The PC hardware for emulating a PS3 is still way too expensive at the moment. And rcpsx3 (I think that's the name of the emulator) isn't quite there yet. All ps3s are able to be jailbroken now, that way you can get pretty much any PS3 game for fee. Find one with/put in a 500GB or 1TB hard drive there (mine came with a 500GB drive from the factory) and you can download a ton of stuff on it. Added bonus of PS2 and PS1 emulation as well (though at native resolution :-( )
Yeah some of the 240p PS2 and PS1 games look a bit jagged, but hey it works. You can see the compatibility here if you're interested in how a particular game runs
