✅100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

❌Lower PassMark (7,349 vs 7,383).
❌46.2% higher power demand at 95W vs 65W.

Quick Answers

So, is Core i7-8706G better than Xeon E5-2650?

Not really, because they are built for different jobs. Xeon E5-2650 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 1.8% 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 0.5% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-8706G still makes the most sense overall. Core i7-8706G comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our 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 2012) 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.
