Quick Answers

So, is Celeron G1840T better than Pentium G870?

It depends on what you want from the system. For gaming, Pentium G870 is ahead with a 0.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G1840T pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron G1840T is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 2 threads.

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

Celeron G1840T is the better buy right now. Celeron G1840T comes in $44 cheaper on MSRP at $42 MSRP versus $86 MSRP, and it still gives you 0.9% better PassMark. The compromise is that Pentium G870 is still the better pure gaming CPU with a 0.7% average FPS lead across 50 shared CPU game tests in our data. It is also 106.6% better value on MSRP (37.5 vs 18.2 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Celeron G1840T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
