Quick Answers

So, is Athlon PRO 3045B better than Athlon X4 850?

It depends on what you want from the system. For gaming, Athlon X4 850 is ahead with a 5.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Athlon PRO 3045B 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 PRO 3045B is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 4 threads.

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

Athlon PRO 3045B is still the much better call for a fresh build. Athlon PRO 3045B comes in 453.2% more expensive on MSRP at $426 MSRP versus $77 MSRP, and it still gives you 0.5% better PassMark. Athlon X4 850 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 450.5% better value on paper (35.8 vs 6.5 PassMark/$), 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?

Athlon PRO 3045B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2015) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
