Quick Answers

So, is Pentium G4520 better than Core i5-3340M?

It depends on what you want from the system. For gaming, Pentium G4520 is ahead with a 3.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-3340M pulls ahead with 0.8% better PassMark. Pentium G4520 also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-3340M is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 4 threads.

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

Pentium G4520 is the better buy right now. Pentium G4520 comes in at an unclear MSRP at $86 MSRP versus unclear MSRP, and it still gives you a 3.6% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-3340M is still stronger for heavier multi-core work with 0.8% better PassMark. It is also 100.0% better value on MSRP (31.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium G4520 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) and 33.3% larger total L3 cache (4 MB vs 3 MB). That makes it the safer long-term bet.
