External Graphics Card Buying Guide

Many computers and laptops come with onboard or integrated graphics, which are great for your everyday tasks like browsing the web or working with documents. However, if you're into gaming or other heavy-duty tasks like video editing, you'll need a graphics card that can handle the processing power needed to complete these tasks.

An external graphics card, also known as an eGPU, is a great way to upgrade the graphics performance of your laptop or desktop computer. An eGPU is a separate graphics card that connects to your laptop or desktop via a Thunderbolt 3 port, allowing you to enjoy the benefits of a dedicated graphics card without having to replace your entire system.

Buying an external graphics card can be intimidating, especially if you're not familiar with the technical specifications and features of these devices. In this buying guide, we'll take a closer look at what to consider when buying an external graphics card.

Compatibility

The first thing you need to consider when buying an external graphics card is compatibility. Not all eGPUs work with all laptops and desktops. The most important factor is the type of connection port. Thunderbolt 3 is the most common port used by external graphics cards. If your computer doesn't have a Thunderbolt 3 port, then you won't be able to use an eGPU.

Another compatibility factor to consider is the power supply. External graphics cards require a lot of power, and your computer's power supply might not be strong enough to handle it. Some eGPUs come with an external power supply to make up for this.

Performance

The main reason to buy an external graphics card is to improve the performance of your computer. This means you need to consider the performance specs of the eGPU you're considering.

One of the most important performance specifications is the graphics processor unit (GPU). The GPU is the main component responsible for processing graphics data. The higher the number of cores in the GPU, the better its performance. Look for eGPUs with at least 4 cores for optimal performance.

Another important specification to consider is the clock speed. The clock speed determines how fast the GPU can process data. A higher clock speed means better performance. A good clock speed for an external graphics card is around 1.5GHz or higher.

Memory is also important when it comes to eGPU performance. The more memory a graphics card has, the more data it can process at once. Look for eGPUs with at least 4GB of memory for optimal performance.

Portability

If you're looking for an eGPU that you can take with you on the go, then portability is an important factor to consider. Some eGPUs are designed to be portable, while others are more suited to stationary use.

When it comes to portability, size and weight are the most important factors to consider. Look for eGPUs that are small enough to fit into a backpack or laptop bag without taking up too much space. Some eGPUs are designed to be compact and portable, while others are bulkier.

You'll also want to look for an eGPU that is easy to connect and disconnect. Some eGPUs require additional power cables or drivers to be installed, which can make them more cumbersome to use on the go.

Price

The price of an external graphics card can vary widely depending on its features and specifications. Expect to pay anywhere from a few hundred dollars to well over $1000 for a high-end eGPU.

If you're on a budget, then you'll need to prioritize which features are the most important to you. It's possible to get a decent eGPU for less than $500, but if you want top-of-the-line performance and features, you'll need to be prepared to spend more.

Conclusion

When it comes to buying an external graphics card, there are several factors to consider, including compatibility, performance, portability, and price. By taking these factors into account, you'll be able to find an eGPU that meets your needs and budget.

Remember that not all eGPUs are created equal, and you'll need to do your research to find the one that's right for you. With the right external graphics card, you'll be able to take your computer's performance to the next level, whether you're a gamer or a graphic designer.

Brand and Quality

When buying an external graphics card, it's important to pay attention to the brand and quality of the device. There are many well-known brands in the market that make high-quality eGPUs, such as ASUS, Razer, and Gigabyte. These brands have a history of producing reliable and powerful devices that are worth the investment.

It's also important to consider the build quality of the eGPU. Look for devices that are made from high-quality materials and have a sturdy feel. A well-built eGPU will last longer and provide higher performance than a poorly made one.

Noise and Heat

External graphics cards can produce a lot of heat and noise, which can be a problem if you're using them in a quiet environment or if you want to avoid overheating your laptop. It's important to consider the noise and heat output of the eGPU when making your purchase.

Look for eGPUs that have built-in cooling solutions, such as fans or liquid cooling systems. These will help to reduce heat and noise levels and keep your device running smoothly. Some eGPUs are also designed to be quieter than others, so pay attention to reviews and specifications to find a device that's suited to your needs.

Upgradability

Another factor to consider when buying an eGPU is upgradability. As technology advances, you may want to upgrade your graphics card to keep up with the latest software and games. Make sure the eGPU you buy is compatible with future upgrades, and that it's easy to replace or upgrade the GPU when the time comes.

Warranty and Support

Finally, it's important to consider the warranty and support that comes with your eGPU. Look for devices that come with a warranty of at least one year, and make sure the manufacturer offers good customer support in case you run into any issues.

Before you buy an eGPU, read reviews online and do your research to find out what other users are saying about the device. This will give you a good idea of any common problems or issues that might arise, and help you make an informed decision.

Conclusion

Buying an external graphics card is a great way to upgrade your computer's performance, whether you're a gamer, graphic designer, or just someone who needs more processing power.

When choosing an eGPU, consider factors like compatibility, performance, portability, price, brand and quality, noise and heat, upgradability, and warranty and support. By taking these factors into account, you'll be able to find the right eGPU for your needs and budget.

At the end of the day, it's up to you to decide which features are most important to you, and which eGPU meets your needs. With the right device, you'll be able to take your computer to the next level and tackle even the most demanding tasks with ease.
