Quick Answers

So, is Xeon D-1813NT better than Core i7-5775C?

Not really, because they are built for different jobs. Xeon D-1813NT makes more sense for workstation-style multi-core throughput, while Core i7-5775C 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-1813NT is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 66.7% larger total L3 cache (10 MB vs 6 MB).

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

Xeon D-1813NT is still the much better call for a fresh build. Xeon D-1813NT comes in at an unclear MSRP at unclear MSRP versus $366 MSRP, and it still gives you 0.6% better PassMark. Core i7-5775C only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (21.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.

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

Xeon D-1813NT makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2015), 66.7% larger total L3 cache (10 MB vs 6 MB), 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.
