Quick Answers

So, is Core i5-10400 better than Xeon E5-2650L v3?

Not really, because they are built for different jobs. Xeon E5-2650L v3 makes more sense for workstation-style multi-core throughput, while Core i5-10400 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i5-10400 is the better pick. According to our tests, it delivers 0.2% 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 i5-10400 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 i5-10400 is the better buy right now. Core i5-10400 comes in $1,147 cheaper on MSRP at $182 MSRP versus $1,329 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data.
