Benchmarks & Specs

Last updated:
The Intel Core i9-12900HX established itself as a powerful mobile processor. It was considered a top-tier model for notebooks at the time. Its foundation is the advanced Alder Lake H architecture. This innovative hybrid architecture combines performance cores and efficiency cores. Thus, the chip enables excellent performance in a wide variety of scenarios.

It demonstrates its strengths especially in demanding applications such as video editing or complex calculations. It offers ample computing power for intensive multitasking and smooth operation. We were surprised ourselves at how well it still holds up today. The generously sized cache memories are an important plus.

With 14 MB L2 and a considerable 30 MB L3 cache, the system benefits from fast data access. This noticeably improves responsiveness and supports overall performance. Manufactured in a 10 nm process, the processor also offers solid energy efficiency. Its integrated Intel UHD Graphics 770 covers everyday graphical requirements.

A maximum memory bandwidth of 83 GB/s rounds off this robust package. The Intel Core i9-12900HX remains a very capable choice for demanding users.
  • Hybrid Architecture (Alder Lake H)
  • High Multi-Core Performance
  • Large Cache Memories (L2 and L3)
