Quick Answers

So, is Pentium 1403 v2 better than Core 2 Duo P7450?

It depends on what you want from the system. For gaming, Pentium 1403 v2 is ahead with a 2.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo P7450 pulls ahead with 1% better PassMark. Pentium 1403 v2 also has the bigger cache pool with 100% larger total L3 cache (6 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core 2 Duo P7450 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Pentium 1403 v2 is the better buy right now. Pentium 1403 v2 comes in at an unclear MSRP at $150 MSRP versus unclear MSRP, and it still gives you a 2.9% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core 2 Duo P7450 is still stronger for heavier multi-core work with 1% better PassMark. It is also 100.0% better value on MSRP (15.2 vs 0.0 PassMark/$), 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 1403 v2 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2009) and 100% larger total L3 cache (6 MB vs 3 MB). That makes it the safer long-term bet.
