✅Draws 45W instead of 150W, a 105W reduction.
✅Newer platform on FCBGA1744 with DDR5 support instead of LGA3647 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Iris Xe Graphics 96EU, while Xeon Gold 6252 needs a discrete GPU.

Trade-offs

❌Lower PassMark (27,079 vs 27,148).
❌Smaller total L3 cache (24 MB vs 36 MB).
❌Less compelling for workstation-style loads than Xeon Gold 6252, which brings 24 cores / 48 threads.
❌Launch MSRP is still $617 MSRP, while Xeon Gold 6252 mostly shows up through inconsistent older-market listings.

Xeon Gold 6252

2019

Why buy it

✅+0.3% higher PassMark.
✅+49% larger total L3 cache (36 MB vs 24 MB).
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i9-12900H across 50 shared CPU benchmark tests.
❌233.3% higher power demand at 150W vs 45W.
❌Older platform position on LGA3647 with DDR4, while Core i9-12900H moves to FCBGA1744 and DDR5.
❌No integrated graphics, while Core i9-12900H can still boot and troubleshoot without a discrete GPU.
