Quick Answers

So, is Celeron G1620 better than Celeron G1840T?

Yes. Celeron G1620 is the better all-around CPU here. It gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data and 0.6% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Celeron G1620 is the better pick. According to our tests, it delivers 1.6% 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, Celeron G1620 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

Celeron G1620 is still the much better call for a fresh build. Celeron G1620 comes in 23.8% more expensive on MSRP at $52 MSRP versus $42 MSRP, and it still gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data. Celeron G1840T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 23.0% better value on paper (37.5 vs 30.5 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.

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

Celeron G1840T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012) and 50% larger total L3 cache (3 MB vs 2 MB). That makes it the safer long-term bet.
