Quick Answers

So, is Atom C3708 better than Athlon X4 845?

It depends on what you want from the system. For gaming, Atom C3708 is ahead with a 7.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Athlon X4 845 pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Athlon X4 845 is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads.

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

Atom C3708 is still the much better call for a fresh build. Atom C3708 comes in at an unclear MSRP at unclear MSRP versus $70 MSRP, and it still gives you a 7.6% average FPS lead across 50 shared CPU game tests in our data. Athlon X4 845 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2016 platform. Even with 100.0% better value on paper (53.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM2+.

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

Atom C3708 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2016). That makes it the safer long-term bet.
