Intel surprised us a few days ago with its top-of-the-range laptop processors with a TDP of up to 55 W. We are referring to the Intel Core 12 HX range. Which are desktop chips adapted to work in workstations and portable high-end gaming systems. Well, the first performance tests of the Core i7-12800HX processor for laptops have come out.
Within the world of laptops there are many variants, from the ultralight fully portable to powerful systems for gaming. Intel’s latest invention to continue to lead the market? Launch the same processors as the desktop, but soldered to the laptop board via BGA instead of using a traditional socket. In addition to making certain cuts in clock speed to be able to reach a TDP of 55 W only for the processor. This leads to the need for special models in order to mount these CPUs.
Otherwise, an Intel Core 12 HX is exactly the same as the desktop models , since it is the same chip. Its main difference? Laptop chips are made up of up to 6 P-Core cores and 8 E-Core cores, while desktop chips have up to 8 P-Core cores. So we can expect an increase in performance compared to the more powerful Intel Core 12H. But, to what extent is there a difference between the two processors of the brand today led by Pat Gelsinger.
i7-12800HX vs i7-12700H, which one is better?
Using two Lenovo laptops with almost identical specifications as a base: an RTX 3070 Ti graphics card, the same amount of RAM and the same storage unit. The comparison between two processors has been made. On the one hand, an i7-12700H with a 6+8 configuration , 24 MB of cache , base speed of 2.3 GHz and Boost of 4.7 GHz . On the other an i7-12800HX with 8+8 configuration and 30 MB cache , also 2.3 GHZ base and 5 GHz maximum speed .
As you can see from one of the graphs in many of the tests both the i7-12700H and the i7-12800HX are on par . This is because they are benchmarks running on a single core and we have to assume that the base clock speed is identical. In contrast, when it comes to gaming performance and running several of them at 1080P with an RTX 3070 Ti for laptops , we see a slight advantage due to the 2 additional cores of the i7-12800HX. As you can see there are differences of 4 or 5 frames per second in the best of cases.
What conclusions can we draw from these figures? We’d like to see the numbers with games running at 1440p, mostly due to the fact that most laptops with this processor will use panels at this resolution. And it is with a greater number of pixels on the screen, it will be where the graphics card is most drowned out. So the lower time per frame is achieved by having a faster processor. Let’s not forget that games are the application capable of using all possible cores well. This is because entire threads and process cores are assigned to various common tasks.
