Quick Answers

So, is Xeon 6781P better than Core i7-9700K?

Not really, because they are built for different jobs. Xeon 6781P makes more sense for workstation-style multi-core throughput, while Core i7-9700K 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 6781P is the stronger fit. You are getting 719.2% better PassMark, backed by 80 cores and 160 threads. It also has the larger cache pool with 2700% larger total L3 cache (336 MB vs 12 MB).

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

Xeon 6781P is still the much better call for a fresh build. Xeon 6781P comes in 2227.3% more expensive on MSRP at $8,960 MSRP versus $385 MSRP, and it still gives you 719.2% better PassMark. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 184.1% better value on paper (37.4 vs 13.2 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Xeon 6781P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2018), a healthier platform with LGA4710 and DDR5 instead of LGA1151, 2700% larger total L3 cache (336 MB vs 12 MB), and more multi-core headroom with 80 cores / 160 threads instead of 8/8. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
