Quick Answers

So, is Core Duo T2400 better than Pentium 2129Y?

It depends on what you want from the system. For gaming, Core Duo T2400 is ahead with a 1.1% average FPS lead across 46 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium 2129Y 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, Pentium 2129Y 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?

Core Duo T2400 is the better buy right now. Core Duo T2400 comes in at an unclear MSRP at $294 MSRP versus unclear MSRP, and it still gives you a 1.1% average FPS lead across 46 shared CPU game tests in our data. The compromise is that Pentium 2129Y is still stronger for heavier multi-core work with 0.9% better PassMark. It is also 100.0% better value on MSRP (5.1 vs 0.0 PassMark/$), 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 2129Y makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2006) 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.
