Quick Answers

So, is Athlon X4 750 better than Core i7-5550U?

It depends on what you want from the system. For gaming, Athlon X4 750 is ahead with a 4.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-5550U 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 i7-5550U 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?

Athlon X4 750 is the better buy right now. Athlon X4 750 comes in at an unclear MSRP at $95 MSRP versus unclear MSRP, and it still gives you a 4.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i7-5550U is still stronger for heavier multi-core work with 1.1% better PassMark. It is also 100.0% better value on MSRP (29.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i7-5550U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) 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.
