Quick Answers

So, is Core i3-10100 better than Xeon E3-1245 v6?

Not really, because they are built for different jobs. Xeon E3-1245 v6 makes more sense for workstation-style multi-core throughput, while Core i3-10100 is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Xeon E3-1245 v6 is the stronger fit. You are getting 2.2% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Core i3-10100 is the better buy right now. Core i3-10100 comes in at an unclear MSRP at $122 MSRP versus unclear MSRP, and it still gives you a 1.3% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E3-1245 v6 is still stronger for heavier multi-core work with 2.2% better PassMark. It is also 100.0% better value on MSRP (69.9 vs 0.0 PassMark/$), 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 i3-10100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2017). That makes it the safer long-term bet.
