Quick Answers

So, is Core i5-5575R better than Core i5-6440HQ?

Yes. Core i5-5575R is the better all-around CPU here. It gives you a 6.0% 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, Core i5-5575R is the better pick. According to our tests, it delivers 6.0% 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, Core i5-5575R is the stronger fit. You are getting 1.1% better PassMark, backed by 4 cores and 4 threads.

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

Core i5-5575R is the easy recommendation for a fresh desktop build. Core i5-5575R comes in 6.0% more expensive on MSRP at $265 MSRP versus $250 MSRP, and it still gives you a 6.0% average FPS lead across 50 shared CPU game tests in our data. Core i5-6440HQ 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 6.0% in the shared gaming data.

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

Core i5-5575R makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 4 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.
