Quick Answers

So, is Pentium G630T better than Celeron 2981U?

It depends on what you want from the system. For gaming, Pentium G630T is ahead with a 0.2% average FPS lead across 40 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 2981U pulls ahead with 0.4% better PassMark. Pentium G630T also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron 2981U is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G630T is the better buy right now. Pentium G630T comes in $58 cheaper on MSRP at $79 MSRP versus $137 MSRP, and it still gives you a 0.2% average FPS lead across 40 shared CPU game tests in our data. The compromise is that Celeron 2981U is still stronger for heavier multi-core work with 0.4% better PassMark. It is also 72.7% better value on MSRP (13.1 vs 7.6 PassMark/$), 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 2981U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2011) 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.
