Quick Answers

So, is Phenom II X2 B57 better than Celeron Dual-Core SU2300?

Yes. Phenom II X2 B57 is the better all-around CPU here. It gives you a 0.9% average FPS lead across 49 shared CPU game tests in our data, 0.8% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Phenom II X2 B57 is the better pick. According to our tests, it delivers 0.9% more average FPS across 49 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Phenom II X2 B57 is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 2 threads.

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

Phenom II X2 B57 is the easy recommendation for a fresh desktop build. Phenom II X2 B57 comes in at an unclear MSRP at unclear MSRP versus $134 MSRP, and it still gives you a 0.9% average FPS lead across 49 shared CPU game tests in our data. Celeron Dual-Core SU2300 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 0.9% in the shared gaming data.

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

Phenom II X2 B57 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009) 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.
