Quick Answers

So, is Xeon D-2799 better than Core i7-9700K?

Not really, because they are built for different jobs. Xeon D-2799 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 D-2799 is the stronger fit. You are getting 134.7% better PassMark, backed by 20 cores and 40 threads. It also has the larger cache pool with 150% larger total L3 cache (30 MB vs 12 MB).

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

Xeon D-2799 is still the much better call for a fresh build. Xeon D-2799 comes in at an unclear MSRP at unclear MSRP versus $385 MSRP, and it still gives you 134.7% better PassMark. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (37.4 vs 0.0 PassMark/$), 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 D-2799 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2018), 150% larger total L3 cache (30 MB vs 12 MB), more multi-core headroom with 20 cores / 40 threads instead of 8/8, and AVX-512 support for heavier modern compute workloads. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
