Intel Core i9 12900HX benchmark leaks

Latest update:

The first indication of Intel Core i9 12900HX performance scores has been discovered online. The Geekbench 5 result found for the upcoming Lenovo 82TD laptop, dated March 10, 2022, shows particularly impressive multi-core performance for the upcoming Intel mobile CPU. We also have some information about the upcoming CPU specs.

If these results hold, The new Intel Core i9 12900HX processor performs 10% better than the previous Intel Core i9 12900H processor in multi-core tasks, although performance is slightly impaired in single-core scenarios (such as gaming) by about 2%. Take a look at this page for a visual representation of how these results compare to the current competition.

Intel Core i9 12900HX Specifications

See below for a list of Intel Core i9 12900HX specifications revealed on the Geekbench page. While all of these seem to be in line with our expectations, remember that these are not certain and concrete at this point.

The new Intel Core i9 12900HX uses the same architecture large and small as other Alder Lake CPUs, featuring more powerful performance cores (p-cores) for more intensive tasks and more energy-efficient efficiency cores (electronic cores) at the cost of fewer challenging tasks. Each core contains two threads, while the electronic core contains only one thread.

Intel Core i9 12900HX Performance vs. Alder Lake and AMD 6000 series Zen 3+

As you can see below, the 12900HX performs very well in the multi-core test, showing substantial gains over the 12900H, which was already eliminating AMD’s leading competition by about 45%. While it doesn’t quite beat the Intel Core i9 12900H in single-core workloads, it’s not far behind, and both processors are still driving AMD’s latest release, the Ryzen 9 6900HX.

It remains to be seen how the upcoming AMD Ryzen 9 6980HX will compete in benchmarks against the best of Intel. More on this below.

Comparing Intel Core i9 12900HX vs AMD Ryzen 9 6980HX

We don’t have any performance data for the upcoming AMD Ryzen 9 6980HX, the high-end flagship of the AMD 6000 series, so we can’t directly compare it to an Intel Core i9 12900HX processor. Certain assumptions can be made:

  • Given that the number of cores/threads for an AMD CPU will be set at 8/16 respectively, It is highly unlikely that the AMD Ryzen 9 6980HX will be able to compete with the Intel Core i9 12900HX in terms of multi-core performance.. This greatly cements Intel’s leadership in 2022 as king of workstation users and others interested in multi-core power, at least until AMD’s Zen 4 comes out at the end of the year.
  • In terms of single-core performance, AMD Ryzen 9 6980HX will likely be able to compete and possibly beat the Intel Core i9 12900HX in single-core benchmarks. We’ll have to wait and see to know for sure.
  • One area where we know the Intel Core i9 12900HX won’t be able to compete with AMD is energy efficiency. To start with, the 12900HX has a TDP of 55W compared to the 45W of the 6980HX. Looking more generally, while Intel’s Alder Lake range has so far impressed in terms of performance, when it comes to battery life in laptops and gaming laptops, it has been soundly beaten by AMD’s series laptops. Ryzen 6000 and revolutionary 6nm Zen 3+ technology in every case so far.
