Low-power processors have been around for a long time. These solutions have allowed the creation of new categories of laptops, lighter and more compact, and also with greater autonomy, and the best thing is that they have not forced us to give up a good level of performance in most cases.
All in all, I know that low-power processors continue to generate some doubts among users, And taking into account the importance they have in professional teams, I wanted to share with you this article where we are going to explain how they make a difference, and what we can expect from them. I’ll also tell you when, and why, they are a good choice.
I start at the beginning. Low Power Processors They are versions that are adjusted in terms of working frequency to run at a lower speed than the standard versions, and to scale to a lower level in its turbo mode. However, they maintain the same number of cores and threads as their equivalent standard versions, and have the same base architecture, so the IPC they offer is the same.
Thus, for example, the Ryzen 7 5800U has 8 cores and 16 threads, uses the Zen 3 architecture and operates at 1.9 GHz-4.4 GHz, normal and turbo mode, but maintains a speed lower than 4 GHz when they work. all their cores at once. In contrast, the Ryzen 7 5800H keeps all those keys and has the same number of cores and threads, but it operates at 3.2 GHz-4.4 GHz, normal and turbo mode, and its frequency scales to a higher level when all the nuclei are active. This means that they yield less, but the difference is not enormous, and they make up for it with other advantages, as we will see below.
Low-power processors also have lower TDP, which means that they generate less heat, and therefore do not need bulky cooling systems. They also consume less energy, which obviously helps improve autonomy. All these keys allow us to understand why with these processors it is possible to create lighter, more compact laptops with greater autonomy.
It is true that, if our priority is performance, we must opt for the standard versions, but if we are going to need high mobility and good autonomy, low-power processors are essential. To show a button, a laptop with a standard processor can be around 6 or 7 hours of autonomy per battery charge, in the best of cases, while low-power processors can extend this autonomy until 2:00 p.m., in some cases.
