Core i7-12700K

2021

Why buy it

✅+27.9% higher PassMark.
✅+56.3% larger total L3 cache (25 MB vs 16 MB).
✅Newer platform on LGA1700 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 Intel UHD Graphics 770, while Ryzen 7 PRO 7840HS needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $409 MSRP, while Ryzen 7 PRO 7840HS mostly shows up through inconsistent older-market listings.
❌1462.5% higher power demand at 125W vs 8W.

Ryzen 7 PRO 7840HS

2023

Why buy it

✅Draws 8W instead of 125W, a 117W reduction.

Trade-offs

❌Lower PassMark (26,852 vs 34,347).
❌Smaller total L3 cache (16 MB vs 25 MB).
❌Older platform position on FP7/FP8, while Core i7-12700K moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i7-12700K can still boot and troubleshoot without a discrete GPU.
