✅Includes a boxed cooler (Laptop Integrated), unlike Xeon Gold 6256.

Trade-offs

❌Smaller total L3 cache (24 MB vs 33 MB).
❌Less compelling for workstation-style loads than Xeon Gold 6256, which brings 12 cores / 24 threads.

Xeon Gold 6256

2020

Why buy it

✅+37.5% larger total L3 cache (33 MB vs 24 MB).
✅Better for workstations and heavier parallel workloads: 12 cores / 24 threads.

Trade-offs

❌Lower PassMark (25,334 vs 25,512).
❌355.6% higher power demand at 205W vs 45W.
❌Older platform position on LGA3647 with DDR4, while Core i9-12900HK moves to FCBGA1744 and DDR5.
❌No integrated graphics, while Core i9-12900HK can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Core i9-12900HK.

Quick Answers
