7 Things You Need to Know About the External GPU

Although it is more practical and traditional to have a GPU inside the PC, it is becoming more common to have an External GPU. This is especially true for notebook-based notebooks, but still wants much higher performance when at home or at work. Just imagine a light and thin notebook with the power of a more rugged, custom-built desktop.

Of course the subject may seem a bit complicated and even unnecessary for those already familiar with traditional GPUs. Still, something that is growing bigger and bigger and gaining more space. So you have no doubt about the External GPU and how it works, we have listed everything you need to know. Check out the details below!

1. How does it work?

External GPU in Notebook

First of all, good to simply know how the external GPU works. It's very similar to a normal GPU that you would plug directly into the motherboard on your PC case, just outside.

Therefore, he needs his own Dock, which has a PCIe slot in which the GPU is placed. This Dock also has a USB or Tunderbolt socket so that it can be connected directly to your computer.

After you make the necessary initial settings for any new GPUs placed on the PC, your machine will redirect the graphics processes to the external GPU. Since most notebooks have very poor GPUs, this already improves performance significantly.

Of course in some cases you may need to do this redirection manually. But it depends a lot on each computer.

2. Worse performance than an internal GPU

Whether or not there is a big difference between connecting a GPU directly to the PC's motherboard and placing it in a PC-connected Dock via USB. That alone would give a performance difference between an external and an internal GPU, but there are still other factors.

Most people who use or search for an external GPU do this with notebooks. That makes more sense, since it's only those portable computers that don't have room for a normal GPU and need more graphics power.

The problem notebooks are not exactly developed with external GPUs in mind. They have limitations and are not always prepared to receive such a powerful component.

This is especially true for older CPUs or notebooks that already have integrated GPUs. The performance loss in these cases can be quite noticeable, especially on heavier software and games.

This is definitely something to consider when considering buying an external GPU. Of course you will get a big improvement on the notebook, just not have the same experience as on a desktop.

3. The dock for a very expensive External GPU

We mentioned earlier that the external GPU needs a special Dock to work. This Dock provides the PCIe input into which the GPU is placed, as well as the way the GPU is connected to the PC.

The problem is that these docks tend to be kind of expensive. Of course the price will depend a lot on the model, but it is normal that they cost from 500 reais upwards, with many costing more than a thousand.

You should also be aware of what type of Dock you want to use. Some let the GPU fully display, while other types fully protect it, like a box.

Another factor to consider is the models that only work with certain brands of notebook. So do a lot of research before you buy yours.

4. Compatibility can be a problem.

If you already have to worry a lot about compatibility issues when building a custom PC, imagine something pre-assembled like a notebook and external parts not made for it.

That's why you should do a good research involving your notebook model, what type of GPU you want to buy and which Docks can be used. See all the requirements of the external GPU you want and your notebook meets them, for example.

Also make sure to check if the Dock and GPU are compatible. This may take a little time, but this kind of research is needed in preparing any PC.

5. Graphic performance will be better

We kinda mentioned that, but it is worth mentioning that the graphics performance of the notebook really improves. It is important to remember this, as obviously some of the disadvantages of the External GPU may make it seem that all this work is not worth it.

Of course it can't compare to the performance of a scratch mount, but an external GPU can do wonders with notebook performance. This may be even more noticeable on Macbooks, which end up being more limited in this regard in many cases.

6. Technology will still improve

Another factor you should consider is that the technology all around the external GPUs will still improve a lot. The practice is becoming more common now, which is already causing companies to pay more attention to it.

This in itself can make Docks more efficient and cheaper to appear, make notebooks built to have better support for external GPUs, and even make more special GPUs built exclusively for use in this way.

In general, it is improvements that should improve the cost-effectiveness of this type of practice and its quality of use.

7. Who is the External GPU worth for?

GPU options

You can see that the external GPU can have many advantages and disadvantages at the same time, in?! While they may be a great option for those who want more notebook performance, the whole device may end up costing the same as a more efficient and powerful desktop.

In general, it may be recommended to expect the use of external GPus to become more common. This is as much for the price of the Docks as for more laptops to be better prepared to receive this kind of GPU without so much performance loss.

Other than that, this scheme is really best recommended for those who don't want to compromise on the convenience and portability of notebooks, while still enjoying the similar power of a desktop in a specific location.
