Simply cost-effective, r7 is definitely better than r5, but there is a problem. If your r7 configuration is lower than r5, then the computer will definitely feel worse when it runs.
Computer performance needs to look at many things, such as your memory, 16g is definitely faster than 8g, and the experience is better.
Among the many notebook brands, which notebook is worth buying? Those who understand notebooks choose this way!

On the other hand, if you have requirements for the transfer speed and the speed of saving files, then solid state drives are definitely better than mechanical hard drives.
If you are on a laptop, then the temperature of the solid state drive must be as low as possible, such as Western Digital. Low temperature is not easy, and it will kill you. Other hardware hits the temperature wall, so that you will not limit the efficiency and working ability of other hardware because of the temperature.
On the other hand, the heat dissipation module is also very important. For example, ASUS Tianxuan 4800h, even though the processor is the same as the rescuer r7000, the overall difference is relatively large, because the relationship between the heat dissipation module leads to the performance of Tianxuan, 274800h and the performance of the rescuer r54600h The difference is not big, so if you want to use a laptop, try to choose some big brands, so the coordination is better, and the heat dissipation module is more excellent.
But you have to be clear that if students are learning to do something and do not need to pursue CPU performance excessively, r54600h is a more choice. Electronic products are updated too fast and there is no one step in place. You only need to meet the current needs. It's enough to buy it.
