Quick Answers

So, is Turion II Neo K685 better than Pentium Dual Core SU4100?

Yes. Turion II Neo K685 is the better all-around CPU here. It gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data, 1.1% 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, Turion II Neo K685 is the better pick. According to our tests, it delivers 2.7% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Turion II Neo K685 is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 2 threads.

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

Turion II Neo K685 is the easy recommendation for a fresh desktop build. Turion II Neo K685 comes in at an unclear MSRP at unclear MSRP versus $134 MSRP, and it still gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data. Pentium Dual Core SU4100 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 2.7% in the shared gaming data.

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

Turion II Neo K685 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.
