Quick Answers

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

It depends on what you want from the system. For gaming, Core i7-8700B is ahead with a 4.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-10505 pulls ahead with 1.8% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-10505 is the stronger 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 better buy right now. Core i5-10505 comes in $111 cheaper on MSRP at $192 MSRP versus $303 MSRP, and it still gives you 1.8% better PassMark. The compromise is that Core i7-8700B is still the better pure gaming CPU with a 4.5% average FPS lead across 50 shared CPU game tests in our data. It is also 60.7% better value on MSRP (62.5 vs 38.9 PassMark/$), 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 i5-10505 makes more sense long term 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 is more likely to matter as games, background tasks, and creator workloads get heavier.
