Users who have bought a notebook should know that Intel has a very wide range of product models in the notebook area, and the suffix is very complex, including M, Y, HQ, MQ, and so on. What does all this mean? Take a look at Intel's official microblogging science.
In general, Intel has several classifications of U, Y, H, M, Q, and X on the notebook processor. The specific meaning is as follows:
U repres
Assembly language is always indispensable in the source code of any operating system. Therefore, assembly language is an essential basic knowledge for learning the operating system. However, at present, most of the teaching in China is conducted on the Windows platform, therefore, most readers are familiar with Intel's Assembly syntax, but att's assembly is used in Linux kernel code. This section compares the two types of assembly, allowing readers who are familiar with

2.6.1 comparison between att and Intel assembly languages
We know that Linux is a member of the UNIX family. Although the history of Linux is not long, many things related to it all originate from UNIX. For Linux's 386 assembly language

Analysis:
I5-3337u can be seen as i5-3230m version (low-power version), performance loss is not small, if the pursuit of performance, select Ultra-polar, light and thin this time choose i5-3337u, otherwise use i5-3230m more suitable
and i5-4200u from a

Note: from top to bottom, the CPU performance is increased from high to low, that is, the t7700 has the highest performance, and the u2300 has the lowest performance. The performance of the CPU type in the same row is not much different. (The functions are not considered)PS: I always thought that the higher the model, the better the p
recently, the well-known foreign primate labs released a new Geekbench 4 testing tools, in addition to supporting cross-platform comparisons, added more dimensional indicators to evaluate CPU and GPU performance, such as the adjustment of integers, floating-point numbers, memory of their respective proportions, Meanwhile, the GPU test (Compute) is added, and the multi-platform contrast is more balanced.
Geekbench 4 is based on
