Quick Answers

So, is Core i7-8706G better than Xeon E3-1565L v5?

Not really, because they are built for different jobs. Xeon E3-1565L v5 makes more sense for workstation-style multi-core throughput, while Core i7-8706G 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 i7-8706G is the better pick. According to our tests, it delivers 7.2% 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 i7-8706G is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-8706G is the easy recommendation for a fresh desktop build. Core i7-8706G comes in at an unclear MSRP at unclear MSRP versus $1,552 MSRP, and it still gives you a 7.2% average FPS lead across 50 shared CPU game tests in our data. Xeon E3-1565L v5 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 7.2% in the shared gaming data.

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

Core i7-8706G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2016) 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.
