Quick Answers

So, is Core i5-5675R better than Xeon E3-1220 v6?

Not really, because they are built for different jobs. Xeon E3-1220 v6 makes more sense for workstation-style multi-core throughput, while Core i5-5675R 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 E3-1220 v6 is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

Core i5-5675R is the better buy right now. Core i5-5675R comes in $33 cheaper on MSRP at $339 MSRP versus $372 MSRP, and it still gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E3-1220 v6 is still stronger for heavier multi-core work with 0.4% better PassMark. It is also 9.2% better value on MSRP (16.4 vs 15.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon E3-1220 v6 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2015), 100% larger total L3 cache (8 MB vs 4 MB), and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
