Quick Answers

So, is Core i9-10900E better than Core i5-10400F?
Yes. Core i9-10900E is the better all-around CPU here. It gives you a 14.0% average FPS lead across 50 shared CPU game tests in our data, 48.4% 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 i9-10900E is the better pick. According to our tests, it delivers 14.0% 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 i9-10900E is the stronger fit. You are getting 48.4% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 66.7% larger total L3 cache (20 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i9-10900E is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. Core i9-10900E comes in 205.0% more expensive on MSRP at $488 MSRP versus $160 MSRP, and it still gives you a 14.0% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 105.6% better value on MSRP (81.4 vs 39.6 PassMark/$), 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 i9-10900E makes more sense long term for 2026 and beyond. You are getting 66.7% larger total L3 cache (20 MB vs 12 MB) and more multi-core headroom with 10 cores / 20 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
