About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

Core i7-12700K

2021

Why buy it

  • Better for gaming: +93.0% higher average FPS across 50 shared CPU benchmark tests.
  • +525% larger total L3 cache (25 MB vs 4 MB).
  • Newer platform on LGA1700 with DDR5 support instead of FP5 and DDR4.
  • 100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Intel UHD Graphics 770, while Ryzen 7 3750H needs a discrete GPU.

Trade-offs

  • Launch MSRP is still $409 MSRP, while Ryzen 7 3750H mostly shows up through inconsistent older-market listings.
  • 257.1% higher power demand at 125W vs 35W.

Ryzen 7 3750H

2019

Why buy it

  • Draws 35W instead of 125W, a 90W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-12700K across 50 shared CPU benchmark tests.
  • Lower PassMark (7,990 vs 34,347).
  • Smaller total L3 cache (4 MB vs 25 MB).
