✅+81.8% larger total L3 cache (30 MB vs 17 MB).
✅Newer platform on LGA1700 with DDR5 support instead of FCBGA2518 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 770, while Xeon D-2166NT needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $409 MSRP, while Xeon D-2166NT mostly shows up through inconsistent older-market listings.
❌47.1% higher power demand at 125W vs 85W.

Xeon D-2166NT

2018

Why buy it

✅Draws 85W instead of 125W, a 40W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-13700K across 50 shared CPU benchmark tests.
❌Lower PassMark (15,105 vs 45,784).
❌Smaller total L3 cache (17 MB vs 30 MB).
❌Older platform position on FCBGA2518 with DDR4, while Core i7-13700K moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i7-13700K can still boot and troubleshoot without a discrete GPU.
