For those of you who care about processors, you may know that Intel's HX series of specs this year basically copy the desktop processor directly to the mobile platform. So does this mean that the mobile HX family is now on par with desktop processors? I tested this question.

I happen to have an i7-13700K processor, which is a pretty good one. It uses intel 7 technology and has eight performance cores and eight energy cores, which make up 16 cores and 24 threads.The basic frequency of the performance core is 3.4GHz and the maximum Rui frequency is 5.3GHz. The base frequency of energy efficiency core is 2.5GHz, the maximum rui frequency is 4.2GHz, the cache is 30MB, the basic power consumption is 125W, the maximum Rui frequency power consumption is 253W.

Let's look at the running score. In the Cinebench R20 test, the multi-core score was 10447pts and the single core score was 682pts, indicating the overall performance was quite outstanding. Which mobile processor model has a similar record?

The answer is i9-13900HX.Measured Cinebench R20 has a multi-core score of 11001pts and a single-core score of 797pts. There is almost no difference between them in multi-core aspects. In the single-core aspect, i9 has a better performance.

Why should this be the case? After all, the i9-13900HX has significantly stronger specifications, with 8 performance cores and 16 energy cores, making up 24 cores and 32 threads. It has 8 more energy efficient cores and 8 more threads than i7-13700K, but the results of multi-core are very close, because of the frequency.

Let's take a look at the i9-13900HX frequency, the performance core maximum Rui frequency is 5.4GHz; The energy efficiency core has a maximum Rui frequency of 3.9GHz, basic power consumption of 55W and maximum Rui frequency power consumption of 157W. It can be seen from this set of data that although i9-13900HX has a higher rui frequency, due to power consumption restrictions, the frequency in the actual test cannot reach the official nominal data, resulting in more cores, but the run score is not much different from i7-13700K.

i9-13900HX has stronger single-core performance, mainly due to higher single-core rui frequency. As can be seen from the above parameters, its rui frequency is higher, and naturally the single-core performance is more brilliant.

As can be seen from the above results, although HX series processors are directly transplanted to the desktop processor core, but due to power consumption, temperature and other reasons, its actual operating frequency is not as high as that of desktop processors, resulting in the situation of "more cores, but similar performance".

If you want a PC with unlimited power consumption and more potential, it makes sense to opt for a desktop processor that offers a higher ceiling, such as the i7 processor tested here, which is on par with the i9 for mobile.

If you don't care about the limits of your processor and are more concerned with day-to-day performance, the low power and adequate performance of mobile platforms is for you.
