Quick Answers

So, is Core i5-7267U better than Athlon II X4 651?

It depends on what you want from the system. For gaming, Athlon II X4 651 is ahead with a 3.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-7267U pulls ahead with 1.1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-7267U is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-7267U is still the much better call for a fresh build. Core i5-7267U comes in at an unclear MSRP at unclear MSRP versus $92 MSRP, and it still gives you 1.1% better PassMark. Athlon II X4 651 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (39.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM1.

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

Core i5-7267U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2011) 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.
