✅Newer platform on LGA1700 with DDR5 support instead of FCBGA2579 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-2775TE needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (20 MB vs 25 MB).
❌Less compelling for workstation-style loads than Xeon D-2775TE, which brings 16 cores / 32 threads.
❌Launch MSRP is still $289 MSRP, while Xeon D-2775TE mostly shows up through inconsistent older-market listings.
❌25% higher power demand at 125W vs 100W.
