Core i7-12700K

2021

Why buy it

✅+23.4% higher PassMark.
✅+56.3% larger total L3 cache (25 MB vs 16 MB).
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 770, while Ryzen 7 7840H needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 7 7840H across 50 shared CPU benchmark tests.
❌Launch MSRP is still $409 MSRP, while Ryzen 7 7840H mostly shows up through inconsistent older-market listings.
❌257.1% higher power demand at 125W vs 35W.

Ryzen 7 7840H

2023

Why buy it

✅Better for gaming: +9.8% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 35W instead of 125W, a 90W reduction.

Trade-offs

❌Lower PassMark (27,832 vs 34,347).
❌Smaller total L3 cache (16 MB vs 25 MB).
❌No integrated graphics, while Core i7-12700K can still boot and troubleshoot without a discrete GPU.
