Quick Answers

So, is Core i5-10400F better than Celeron 1047UE?
Yes. Core i5-10400F is the better all-around CPU here. It gives you a 945.8% average FPS lead across 34 shared CPU game tests in our data, 1873.7% better Geekbench multi-core, 1830.2% higher 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 i5-10400F is the better pick. According to our tests, it delivers 945.8% more average FPS across 34 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-10400F is the stronger fit. You are getting 1873.7% better Geekbench multi-core, backed by 6 cores and 12 threads. It also has the larger cache pool with 500% larger total L3 cache (12 MB vs 2 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-10400F is the better buy right now. Core i5-10400F comes in 60.0% more expensive on MSRP at $160 MSRP versus $100 MSRP, and it still gives you a 945.8% average FPS lead across 34 shared CPU game tests in our data.
