Quick Answers

So, is Core i5-10505 better than Core i7-8700B?

Yes. Core i5-10505 is the better overall CPU here. You are getting a 2.4% average FPS lead across 4 shared CPU game tests in our data, 1.8% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.

Which one is better for gaming?

For gaming, the two CPUs are effectively a wash in the available data.

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

For streaming, content creation, and heavier multitasking, Core i5-10505 is the better fit. You are getting 1.8% better PassMark, backed by 6 cores and 12 threads.

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

Core i5-10505 is the smarter buy today. Core i5-10505 is $111 cheaper on MSRP at $192 MSRP versus $303 MSRP, and it gives you a 2.4% average FPS lead across 4 shared CPU game tests in our data. It is also 60.7% better value on MSRP (62.5 vs 38.9 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

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

Core i5-10505 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2018) and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
