Quick Answers

So, is Core i5-1145GRE better than Xeon E3-1260L v5?
Not really, because they are built for different jobs. Xeon E3-1260L v5 makes more sense for workstation-style multi-core throughput, while Core i5-1145GRE 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 E3-1260L v5 is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-1145GRE is the better buy right now. Core i5-1145GRE comes in at an unclear MSRP at $362 MSRP versus unclear MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E3-1260L v5 is still stronger for heavier multi-core work with 0.4% better PassMark. It is also 100.0% better value on MSRP (22.7 vs 0.0 PassMark/$), 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 i5-1145GRE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2015). That makes it the safer long-term bet.
