Quick Answers

So, is Core i7-8705G better than Xeon E5-2640 v2?

Not really, because they are built for different jobs. Xeon E5-2640 v2 makes more sense for workstation-style multi-core throughput, while Core i7-8705G 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, Core i7-8705G is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-8705G is the better buy right now. Core i7-8705G comes in $3,715 cheaper on MSRP at $400 MSRP versus $4,115 MSRP, and it still gives you 0.1% better PassMark. The compromise is that Xeon E5-2640 v2 is still the better pure gaming CPU with a 7.9% average FPS lead across 50 shared CPU game tests in our data. It is also 929.8% better value on MSRP (19.1 vs 1.9 PassMark/$), 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 i7-8705G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2013) and more multi-core headroom with 4 cores / 8 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
