Quick Answers

So, is Core i5-1145GRE better than Xeon E3-1230 v6?

Not really, because they are built for different jobs. Xeon E3-1230 v6 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 gaming?

If gaming is the priority, Core i5-1145GRE is the better pick. According to our tests, it delivers 2.6% 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 i5-1145GRE is the stronger fit. You are getting 1.2% 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 $362 MSRP versus unclear MSRP, and it still gives you a 2.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (22.7 vs 0.0 PassMark/$), 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 2017) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
