Quick Answers

So, is Core i5-6500T better than Xeon E3-1220 v2?

Not in a simple one-size-fits-all way. Xeon E3-1220 v2 makes more sense for workstation-style multi-core throughput, while Core i5-6500T is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

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

For streaming, content creation, and heavier multitasking, Core i5-6500T is the better fit. You are getting 1.8% better PassMark, backed by 4 cores and 4 threads.

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

Core i5-6500T is the smarter buy today. Core i5-6500T is at an unclear MSRP at $117 MSRP versus unclear MSRP, and it gives you 1.8% better PassMark. The trade-off is that Xeon E3-1220 v2 is still the better pure gaming CPU with a 1.2% average FPS lead across 4 shared CPU game tests in our data. It is also 100.0% better value on MSRP (40.7 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

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

Core i5-6500T is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012) and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
