Intel's Core i7-12650HX mobile CPU is so powerful it surpasses the fastest Rocket Lake desktop chips on UserBenchmark
The Intel Core i7-12650HX, Intel Core i9-12900HX, and the top-of-the-tree Intel Core i9-12950HX have all made initial appearances on the controversial synthetic benchmark UserBenchmark. While comparing Intel parts with AMD processors has become something of a Sisyphean task on the site due to its long-standing animosity to all things Team Red, the benchmark is still fine to use for discovering new chips and comparing them with CPUs from the same company’s previous generation. So here we have Alder Lake-HX mobile processors from 2022 distinguishing themselves (one in particular at the time of writing) against 2021’s best Rocket Lake desktop chips.
Surprisingly, it is the Intel Core i7-12650HX that strikes the highest blow, slotting into 12th place in UserBenchmark’s average bench chart (and yes, that is higher than the AMD Ryzen 9 5900X and Ryzen 7 5800X3D but ‘nuff said). The 14-core, 20-thread mobile part scores 104% while the 16-core, 24-thread i9-12950HX and i9-12900HX have to settle in 15th and 19th positions, respectively, on 102%. It seems this state of affairs is simply down to the i7 processor being able to achieve a higher average clock rate during testing thus producing better 1-core and 2-core results. The i7-12650HX managed 4.05 GHz average turbo while all the i9 samples (three tested in total so far) were recorded at 3.6-3.8 GHz.
Impressively for Intel, the Core i7-12650HX, which will likely turn up in powerful gaming and workstation laptops (for instance, the Lenovo Legion 7i will offer choices between the i7-12800HX and i9-12900HX), managed to outpace the fastest desktop processors from the Rocket Lake series, the Intel Core i9-11900KF and i9-11900K. Both of these latter chips sit on an average benchmark score of 103%, which doesn’t really tell the whole story when it comes to showing just how much more performance can be expected from the Alder Lake-HX part in comparison. When compared to the i9-11900KF, the i7-12650HX actually manages incredible marks: 114% vs. 110% (normal), 121% vs. 110% (heavy), and 132% vs. 112% (server). No doubt the i9-12900HX and i9-12950HX will soon catch up as more samples are tested.
