We concluded that the Pentium G4600, like the Pentium G4560, performs pretty much like the Core i3-7100. This was actually expected since the only difference between them is 300 MHz in the clock rate.
The Pentium G4560, on the other hand, has a lower-end integrated GPU, and 100 MHz lower clock. If you use a dedicated video card, the Pentium G4560 and the G4600 will perform similarly so you should just buy the less expensive one. But if you’ll be using integrated video, it’s worth buying the Pentium G4600, even if it costs a little more.
The Pentium G4600 is an excellent choice to build a budget PC, for work or gaming: it has an excellent cost/benefit ratio in both situations.
