Quick Answers

So, is Core i7-4578U better than Pentium G4600T?

Yes. Core i7-4578U is the better all-around CPU here. It gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data and 0.4% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-4578U is the better pick. According to our tests, it delivers 2.2% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i7-4578U is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-4578U is still the much better call for a fresh build. Core i7-4578U comes in at an unclear MSRP at unclear MSRP versus $75 MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data. Pentium G4600T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (40.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

Which one is more future-proof for 2026 and beyond?

Pentium G4600T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2014). That makes it the safer long-term bet.
