Sep 06, 2018 It’s difficult to say exactly how much of a boost your external GPU will give, or even how easy it’ll be to get everything up and running. However, if your laptop cannot run a particular game and you really want it to, an external graphics card is a viable solution. External GPUs Will Only Get Better. With Apple equipping all its recent Macs with Thunderbolt 3 ports, using an external GPU – or eGPU – is a very convenient way to boost graphics performance. Apple already sells two of them.

External GPUs are in the news lately, what with NVIDIA's announcement offering macOS drivers for its Titan Xp and Apple offering an eGPU Developer Kit for High Sierra, so we thought we'd take a second to explain what, exactly, an external GPU is — and how you'd go about getting one.
External GPUs: Supercharging gaming and video production
All Macs have a CPU, which provides the primary processing power for your computer. But in addition, they have a GPU — a graphics processing unit — designed to drive your computer's screen, external displays, and visuals.

GPUs are what sell high-end Windows gaming laptops and desktops: They keep your favorite game flawless, your external display running smoothly, and visual effects rendering speedy. They're also very important in rendering VR experiences.
But all that power comes at the expense of battery and optimization: Heavy-duty GPUs are frequent power hogs with lots of fan noise and problematic battery life. As such, Apple has historically trended toward putting in GPUs that balanced power with optimization: great for your laptop's battery life; not so great for gamers, VR, or visual effects artists.
Enter external GPUs: Like external hard drives, these essentially allow you to stick a GPU in a Thunderbolt housing, where you can then connect it to your computer; from there, when you run games, VR, and visual apps optimized for that GPU you should see significant performance improvements. Awesome, right? Well, almost.
The cons of an external GPU on your Mac
Here's the issue: Macs won't officially support external GPUs until macOS High Sierra. That's not to say you can't use an external GPU on older operating systems — only that Apple Support won't bail you out if you do something that doesn't agree with your Mac. Proceed at your own risk, here be dragons, et cetera.
In addition, should you decide to use an external GPU, there are only a handful of Thunderbolt enclosures and graphics cards with appropriate Mac drivers — you can't just pick an arbitrary graphics card you'd like to attach to your Mac.

External graphics processing units (eGPUs) sound great. You can get desktop-quality graphics on a laptop, which means you only need one computer for portability and high-level gaming.
But do they stand up against internal GPUs? Is it worth dropping a few hundred bucks on a dock? How much performance can you really expect? Unfortunately, expectations and realities may differ with external GPUs.
But they can still be useful. Let’s take a look.
1. How Do External GPUs Work?
In most cases, you’ll see an external GPU hooked up to a dock. An external GPU dock has a PCIe port for the graphics card and usually either a Thunderbolt or USB-C cable to connect to your computer.
Using a dock is as a simple as installing the card, installing the drivers, rebooting, and installing any custom software. (Of course, your experience will vary depending on your hardware.)
Once you have it set up, your computer routes graphics requests to the external GPU instead of the default one supplied with your computer. In theory, this process will get you better graphics performance as, by and large, laptops don’t have much graphical processing power. (Bear in mind that you can use an external GPU for your desktop, but they are much more common for laptops.)
By using the bigger, more powerful card, you get better graphical performance. Maybe even enough to play some graphically intense games. Sounds great, right?
2. External Performance Doesn’t Stack Up
Unfortunately, using an external GPU doesn’t give you the same performance as it would if you had the same GPU mounted internally. How much performance do you lose, then? Estimates put the loss at around 10 to 15 percent. That isn’t a big deal, especially considering the monstrous capacity of the latest high-end graphics cards you can buy today.
However, the loss is something worth knowing about. If you’re hoping to play the latest AAA titles on ultra-high settings, an external laptop GPU setup might not do it for you. That’s not to say the external GPU won’t improve the graphical performance of your laptop; it definitely will. But the gains might not be as game-changing as you think.
Why not? Mostly because laptops just aren’t set up to handle that much power. And if they are, there’s a strong chance the laptop has an integrated GPU already, negating the need for an external GPU. Furthermore, while a PCIe port can transfer a lot of data very quickly, even the latest Thunderbolt and USB-C ports cannot match that data rate.

Your laptop CPU probably wasn’t designed to handle a powerful external GPU, either. Again, it’s not a deal-breaker, but you might notice the effects. https://yvknjpw.weebly.com/siri-for-mac-book.html. This is especially true for older and slower CPUs.
3. External GPU Docks Are Expensive
Though an external GPU dock is basically just a small piece of motherboard with a PCIe port and a connector cord, you can end up shelling out a surprising amount. You’re looking at a couple hundred bucks or more. And that’s on top of the already expensive GPU to go in the dock. (Not forgetting the existing cost of your laptop, of course.)
Some docks are also only compatible with certain brands of laptops, which means you won’t be able to transfer them if you get a new one. That’s another cost to consider. On the flipside, many laptops that aren’t officially certified to work with a specific external GPU dock will, in fact, work just fine. You might have to do a little bit of tinkering to get them working.
4. Research Is Important
External GPU docks have a wide variety of compatibilities and features. https://yvknjpw.weebly.com/idle-for-mac.html. For example:
- The OWC Mercury Helios 3 will only take cards up to 75″.
- The Akitio Node takes “half-length” cards.
- Alienware’s Graphics Amplifier doesn’t have any USB or Thunderbolt ports; it uses a proprietary connector instead.
- The HP Accelerator Omen has a SATA port for connecting an additional HDD or SSD.
In addition, each of the listed external GPUs comes with specific compatibility requirements that you may or may not need to consider. As previously mentioned, the Alienware Graphics Amplifier has a proprietary connector and will only work with Alienware laptops. The Razer Core external GPU dock only works with Thunderbolt 3.

In short, if you want an external GPU, you need to spend some time researching to make sure it’s going to work. Fortunately, there are a huge number of people interested in external GPUs, and they’ve already tested many combinations.

5. You Will Get Better Graphics Performance
Despite the drawbacks, external graphics cards do work. You will get better graphics performance out of your laptop and they’ll enable you to play games or run apps that wouldn’t have worked before. (Which upgrades improve your PC performance the most overall?) There are plenty of benchmarks showing that external GPUs provide a huge boost in graphics power, especially in MacBooks.
It’s difficult to say exactly how much of a boost your external GPU will give, or even how easy it’ll be to get everything up and running. However, if your laptop cannot run a particular game and you really want it to, an external graphics card is a viable solution.
6. External GPUs Will Only Get Better
The Thunderbolt/USB-C bandwidth issue isn’t going to alleviate magically. External GPU hardware and software will continue to improve and it’s more than likely that external GPUs will continue to improve.
Many people are interested in external GPUs. Additionally, hardware manufacturers want to get their GPUs into more people’s hands. As such, there’s plenty of incentive for them to keep improving the technology.
7. What Are the Best External Graphics Cards?
Finally, there are several excellent external GPU options available, depending on your budget and requirements. Here are three for you to consider:
Best Nvidia External GPU: Gigabyte AORUS Gaming Box
