Table of Contents Table of Contents

The first indication of Intel Core i9 12900HX performance results has been discovered online. A Geekbench 5 score for an upcoming Lenovo 82TD laptop has been found, dated to March 10th 2022, which shows superb multi-core performance in particular for the upcoming Intel laptop CPU. We’ve also got some information on the specifications of the upcoming CPU.

If these results are to be believed, the new Intel Core i9 12900HX performs 10% better than the preceding Intel Core i9 12900H in multi-core tasks, though slightly underperforms in single-core scenarios (such as gaming) by around 2%. Have a look further down 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 the Intel Core i9 12900HX specifications that were revealed on the Geekbench page. Whilst these all seem to match up with our expectations, do remember that these aren’t confirmed and concrete at this stage.

The new Intel Core i9 12900HX uses the same big & little architecture as the other Alder Lake CPUs, incorporating the more powerful performance cores (p-cores) for more intensive tasks and the more energy-efficient efficiency cores (e-cores) for less demanding tasks. P-cores each have two threads, whereas e-cores only have one.

Intel Core i9 12900HX performance vs Alder Lake vs AMD 6000 series Zen 3+

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

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

Intel Core i9 12900HX vs AMD Ryzen 9 6980HX

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

• Given that the number of cores/threads of the AMD CPU will be capped at 8/16 respectively, it’s very 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 pretty much cements Intel’s lead in 2022 as the king for workstation users and others interested in multi-core power, at least until AMD’s Zen 4 comes out towards the end of the year.
  
• In terms of single-core performance, it’s probable that the AMD Ryzen 9 6980HX will be able to compete with, 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 that we know the Intel Core i9 12900HX will not be able to compete with AMD in is power efficiency. To start with, the 12900HX has a TDP of 55W compared to the 45W of the 6980HX. Looking more generally, whilst Intel’s Alder Lake range have so far impressed in performance terms, when it comes to battery life in laptops and gaming laptops, they’ve been soundly trounced by the AMD Ryzen 6000 series laptops and their revolutionary 6nm Zen 3+ tech in every instance so far.
