Quick Answers

So, is Core i3-2377M better than Phenom II X3 B77?

It depends on what you want from the system. For gaming, Phenom II X3 B77 is ahead with a 1.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-2377M pulls ahead with 0.3% better PassMark. Phenom II X3 B77 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 i3-2377M is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-2377M is the better buy right now. Core i3-2377M comes in $31 cheaper on MSRP at $250 MSRP versus $281 MSRP, and it still gives you 0.3% better PassMark. The compromise is that Phenom II X3 B77 is still the better pure gaming CPU with a 1.4% average FPS lead across 50 shared CPU game tests in our data. It is also 12.8% better value on MSRP (7.4 vs 6.6 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i3-2377M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2010) and more multi-core headroom with 2 cores / 4 threads instead of 3/3. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
