Quick Answers

So, is Core i5-11500B better than Core i5-11400F?

Yes. Core i5-11500B is the better all-around CPU here. It gives you a 14.8% average FPS lead across 50 shared CPU game tests in our data, 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 i5-11500B is the better pick. According to our tests, it delivers 14.8% 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 i5-11500B is the stronger fit. You are getting 1% better PassMark, backed by 6 cores and 12 threads.

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

Core i5-11500B is still the faster CPU overall, but Core i5-11400F is easier to justify if budget matters more than peak performance. Core i5-11500B comes in 17.8% more expensive on MSRP at $185 MSRP versus $157 MSRP, and it still gives you a 14.8% average FPS lead across 50 shared CPU game tests in our data. Core i5-11400F is also 16.6% better value on MSRP (107.7 vs 92.3 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-11500B makes more sense long term for 2026 and beyond. You are getting 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.
