See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i7-8700K

2017

Why buy it

✅Better for gaming: +37.5% higher average FPS across 50 shared CPU benchmark tests.
✅+20% larger total L3 cache (12 MB vs 10 MB).
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 630, while Xeon D-1823NT needs a discrete GPU.

Trade-offs

❌Lower PassMark (13,572 vs 13,673).
❌Launch MSRP is still $359 MSRP, while Xeon D-1823NT mostly shows up through inconsistent older-market listings.
❌72.7% higher power demand at 95W vs 55W.

Xeon D-1823NT

2023

Why buy it

✅+0.7% higher PassMark.
✅Draws 55W instead of 95W, a 40W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-8700K across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (10 MB vs 12 MB).
❌No integrated graphics, while Core i7-8700K can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon D-1823NT better than Core i7-8700K?

Not really, because they are built for different jobs. Xeon D-1823NT makes more sense for workstation-style multi-core throughput, while Core i7-8700K 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-1823NT is the stronger fit. You are getting 0.7% better PassMark, backed by 6 cores and 12 threads.

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

Xeon D-1823NT is still the much better call for a fresh build. Xeon D-1823NT comes in at an unclear MSRP at unclear MSRP versus $359 MSRP, and it still gives you 0.7% better PassMark. Core i7-8700K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (37.8 vs 0.0 PassMark/$), 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-1823NT makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017) and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
