Pentium G640

2012

Why buy it

✅+1.5% higher PassMark.

Trade-offs

❌Smaller total L3 cache (3 MB vs 4 MB).
❌Launch MSRP is still $64 MSRP, while Core i3-L13G4 mostly shows up through inconsistent older-market listings.
❌828.6% higher power demand at 65W vs 7W.
❌No integrated graphics, while Core i3-L13G4 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium G640 better than Core i3-L13G4?

Yes. Pentium G640 is the better all-around CPU here. It gives you 1.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, Pentium G640 is the stronger fit. You are getting 1.5% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G640 is the better buy right now. Pentium G640 comes in at an unclear MSRP at $64 MSRP versus unclear MSRP, and it still gives you 1.5% higher PassMark. It is also 100.0% better value on MSRP (21.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible FC-CSP1016 + DDR4 setup, Core i3-L13G4 can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

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

Core i3-L13G4 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2012) and 33.3% larger total L3 cache (4 MB vs 3 MB). That makes it the safer long-term bet.
