Core i9-12900H

2022

Why buy it

✅+0.8% higher PassMark.
✅+50% larger total L3 cache (24 MB vs 16 MB).
✅Newer platform on FCBGA1744 with DDR5 support instead of FP7/FP8 and older memory support.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Iris Xe Graphics 96EU, while Ryzen 7 PRO 7840HS needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $617 MSRP, while Ryzen 7 PRO 7840HS mostly shows up through inconsistent older-market listings.
❌462.5% higher power demand at 45W vs 8W.

Ryzen 7 PRO 7840HS

2023

Why buy it

✅Draws 8W instead of 45W, a 37W reduction.

Trade-offs

❌Lower PassMark (26,852 vs 27,079).
❌Smaller total L3 cache (16 MB vs 24 MB).
❌Older platform position on FP7/FP8, while Core i9-12900H moves to FCBGA1744 and DDR5.
