How much worse? Comparison of mobile and desktop processors

Today's desktop processors and mobile processors are similar in name, so often when a small partner purchases a laptop, he asks, what processor is equivalent to a desktop computer? Indeed, even though their names are similar, the gap is really a bit big. Let's learn about it with Xiaobian today.

Don't be fooled by the name! We are not the same

Intel desktop what level is a few core, a few threads, are quite rules, but to the same name of the notebook processor may not be the case, not only different from the desktop, and even with the series are also different, we can refer to the following Chart.

From the table, U series (low voltage) notebook processor specifications are almost one grade lower than desktop processors, such as i5-8250U performance is roughly equivalent to i3-8100, and i7-8550U is roughly equivalent to i5- 8400. The H version (standard voltage) mobile processor has no difference in performance grades. For example, the i7-8750H can be regarded as a low-frequency version of the i7-8700, but the performance gap has reached 20%. Do not assume that it is basically equivalent, but it does Better than desktop i5 8 generations. The difference between i5-8300H and desktop i5-8400 is 15%, and the performance also exceeds i3 desktop product.

AMD mobile processors are similar, in which the Ryzen 7 2700U's 4 cores/8 threads is only equivalent to the desktop Ryzen 5 1400, while the other Ryzen mobile version of the CPU part is not the problem, but the built-in GPU configuration is also more streamlined than the desktop version A lot, such as 8 display cores of Ryzen 5 2500U, is only equivalent to the desktop Ryzen 3 2200G.

What is the difference in performance?

From a structural point of view, how is the performance? Let's take a look at the test data.

It can also be seen from the table that the single-core capabilities of the same-level processors are similar, and the daily use of these core processors and thread-use processors is not too different from that of the desktop processors. As for gaming capabilities, the impact of notebook graphics cards is much greater than that of processors. In addition to flagship processors, the game performance gap between other notebooks and desktop processors of the same level is not particularly large.

Look U choose this? There's nothing wrong with this

Low-voltage U series processors notebooks are mostly thin and light products, the pursuit of high life and light, of course, because the number of 8 generations of core increases, performance is much better than before, many models suitable for office home, carrying more convenient. Standard pressure processor notebooks, now mostly commercial models and game models, they pay more attention to high-end applications, usually with more high-end graphics cards, radiators and other configurations, so the volume weight will be slightly larger.

It is always unrealistic to expect laptop performance to be a desktop computer. Fortunately, there is no urgent need for hardware upgrades for computer applications. In general terms, notebooks using low-voltage processors can be purchased at a price of 4,000 yuan. Because of the high peripheral configuration of notebooks for standard-pressure processors, the price starts at more than 5,000 yuan.
