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

Core i7-9800X

2018

Why buy it

✅Better for gaming: +21.9% higher average FPS across 50 shared CPU benchmark tests.
✅100+% more PCIe lanes (44 vs 0) for storage and expansion-heavy builds.
✅AVX-512 support for select workstation, AI, and scientific workloads.

Trade-offs

❌Smaller total L3 cache (17 MB vs 22 MB).
❌Less compelling for workstation-style loads than Xeon D-2187NT, which brings 16 cores / 32 threads.
❌Launch MSRP is still $589 MSRP, while Xeon D-2187NT mostly shows up through inconsistent older-market listings.
❌50% higher power demand at 165W vs 110W.

Xeon D-2187NT

2018

Why buy it

✅+33.3% larger total L3 cache (22 MB vs 17 MB).
✅Better for workstations and heavier parallel workloads: 16 cores / 32 threads.
✅Draws 110W instead of 165W, a 55W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-9800X across 50 shared CPU benchmark tests.
❌Lower PassMark (18,070 vs 18,128).
❌No AVX-512 support for niche heavy compute workloads where it can matter.

Quick Answers

So, is Core i7-9800X better than Xeon D-2187NT?

Not really, because they are built for different jobs. Xeon D-2187NT makes more sense for workstation-style multi-core throughput, while Core i7-9800X 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 i7-9800X is the better pick. According to our tests, it delivers 21.9% 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 i7-9800X is the stronger fit. You are getting 0.3% better PassMark, backed by 8 cores and 16 threads.

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

Core i7-9800X is the better buy right now. Core i7-9800X comes in at an unclear MSRP at $589 MSRP versus unclear MSRP, and it still gives you a 21.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (30.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i7-9800X makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 8 cores / 16 threads instead of 16/32 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.
