it is VERY hard to upgrade a CPU on a Laptop - because its soldered onto the Laptops Motherboard!
so best would be if you simply buy a new laptop.
Acer Nitro 5 or Asus TUF Gaming FX505DY with Ryzen 5 3500U or better would be a good upgrade and wont break your bank.
either go with the GTX 1050ti or RX560X - enough for 768p ~80-100fps or 1080p 50-60fps in most games
PC: R7 2700X @PBO + RX 580 4G (1500MHz/2000MHz CL16) + 32G DDR4-3200CL14 + 144hz 1ms FS P + 75hz 1ms FS
Laptop: R5 2500U @30W + RX 560X (1400MHz/1500MHz) + 16G DDR4-2400CL16 + 120Hz 3ms FS
