If you’re looking to lớn build or upgrade your PC or simply want lớn learn more about the basics of PC hardware, it’s wise lớn start with PCIe. In this article, we’ll explain the basics of this piece of tech and offer an outline of the popular tăng cấp options & components you can add to your thiết lập.
PCIe is short for “peripheral component interconnect express” & it’s primarily used as a standardized interface for motherboard components including graphics, memory, and storage.
PCIe gets the “peripheral component interconnect” part of its name because it’s designed lớn handle point-to-point connections for non-core components. Manufacturers added “express” khổng lồ distinguish the new standard from older PCI standards, emphasizing the substantial performance improvements over previous iterations.
A PCIe or PCI express slot is the point of connection between your PC’s “peripheral components” and the motherboard. The term “PCIe card” and “expansion card” simply refers to lớn hardware, lượt thích graphics cards, CPUs, solid-state drives (SSDs), or HDDs, you may add khổng lồ your device through PCIe slots, making both catch-all terms for a variety of components.
While different sizes và configurations vì exist, most users will only encounter four primary size specifications. The kích thước represents the number of direct connections provided by either a PCIe slot or thẻ.
These connections are typically called lanes &, in most cases, the more you have, the better your hardware can persize. To maximize efficiency, high-performance devices tend khổng lồ rely on PCIe x16 almost exclusively. This makes them especially useful for competitive gamers or anyone working with visuals.
These components typically don’t have sầu too much hidden baggage, though it’s always important khổng lồ kiểm tra the specs if you aren’t sure about something. Not all PCIe ports offer the same number of available ratings, even if they appear khổng lồ be physical matches.
Historically, updates to lớn PCIe doubled transfer rates và used multiples of 8 since generation 3.0. New generations also offer double the bandwidth versus previous versions, dramatically increasing the amount of data that can be transferred per second. Your benefit is maximized when using ports and cards of the same generation.
With PCIe 4.0, bandwidth capađô thị is 64 gigabytes per second at a rate of 16 gigatransfers per second (GT/s). For users with aging devices – those manufactured several years prior khổng lồ the latest version – there is great potential for improvement with newer tech.
PCIe has seen substantial changes over the years, with big improvements khổng lồ efficiency and the addition of more incidental features. In 2020, the turnover on new updates looks quicker than ever. For the consumer, this all should translate inlớn better hardware performance as new generations are introduced.
While the options for upgrades and add-ons depend on your PC’s motherboard, most consumer desktop devices ship with extra PCIe slots. They present a host of different opportunities for upgrades, with some being extremely niđậy & others applying lớn just about every user. Here are several popular options.
Upgrading your PC’s graphics potential is a great PCIe project for numerous reasons. If your PC has integrated graphics, adding a discrete graphics card can dramatically improve the visual output. Simply choose your preferred graphics card from NVIDIA or AMD, & install it in the best-rated available PCIe port.
Upgrading a busted or lower-quality sound card is another easy way to lớn improve your multitruyền thông experience through PCIe. If you’re swapping out a malfunctioning component, you should notice an immediate difference. In most cases, installation involves deactivating the existing audio và adding your new sound thẻ.
It’s worth noting that installing a new sound thẻ isn’t always as necessary as a new graphics thẻ. In fact, you may just need the right audio accessories, like new speakers or headphones, khổng lồ experience a top-shelf audio experience. Cheông xã out your existing hardware specs và vị a little research before you choose to nâng cấp.
TV tuner cards và đoạn phim capture cards are another media-related application, though these days most cards combine both functions. You can use tuner cards khổng lồ allow your PC to receive conventional TV signals, though some cards have applications beyond đoạn phim, including FM radio access.
As for video capture cards, they provide a more dynamic size of record functionality. They’re increasingly popular these days with the prevalence of streamers and competitive sầu gamers. With đoạn phim capture functionality or a dedicated card, it’s easy khổng lồ produce high-quality video clip of gameplay or whatever entertainment you deliver to your audience.
All of these applications are frequently bundled for convenience, often in a variety of combinations. If you want to lớn tichồng a few boxes off at once, make sure you shop for a thẻ that supports all three functions; TV, radio, & đoạn Clip capture.

Many PCs & laptops already include wireless internet connectivity, but a standalone WiFi thẻ can be particularly useful in a few scenarios. For example, it’s a great way to lớn supplement a weaker signal when you’re experiencing router or connection issues. You can even use it to bypass a malfunctioning or inconsistent built-in system altogether if you prefer.
You can also add a modem card khổng lồ your thiết lập. Sure, most of us aren’t looking to add a new phone line or dial-up mạng internet connection, so you may be wondering: when would I ever need a modem card? There are plenty of potential applications, especially if you’d lượt thích khổng lồ enjoy fax functionality for business or private use.
One extremely comtháng use of PCIe slots is upgrading or adding new local storage. Mounting an SSD on your motherboard through a PCIe connection allows for higher efficiency, và it’s ikhuyễn mãi giảm giá for those with large data files who need capađô thị & tốc độ.
You can also use extra PCIe connections lớn mount a RAID controller that can manage your complete storage array. RAID arrays are a great way to upgrade your storage across the board. Some of this functionality is built-in with many modern motherboards, so you may not always need it for your situation.

The largest and lachạy thử PCIe standard is PCIe 4.0, but it won’t get top billing for too much longer. Version 5.0 was unveiled in 2019 và is due for implementation in 20trăng tròn, making it technically the most up-to-date PCIe standard. While 4.0 provides bandwidth capacity of 64 GB/s at 16 GT/s, 5.0 can deliver 128 GB/s at 32 GT/s.
We shouldn’t expect to see PCIe 6.0 released until 2021 or later in terms of full-on implementation, but it’s already in development. It’s expected khổng lồ match typical generation changes, offering double bandwidth capađô thị at 256 GB/s at a rate of 64 GT/s. That means performance is on the up, and moving more quickly than ever when it comes to PCIe technology.
One of the most important things lớn rethành viên about PCIe is how to handle compatibility. With PCIe connections, you can hook up smaller connections khổng lồ large ports. You can also connect larger connections to lớn smaller ports. But using two different size configurations to lớn complete liên hệ can have some negative consequences.
In particular, these connections suffer from a substantial decrease in bandwidth. Placing a larger card in a smaller port has a higher negative sầu impact on the unique of your experience, but you can still see less than optimal performance the other way around as well.
PCIe formats are changing faster than ever, and the performance gains with each update are substantial. As a result, it has never been easier to fine-tune and improve your experience with relatively simple hardware upgrades or add-ons.
Curious to lớn learn more about PCIe? The standard is developed và maintained by an organization called PCI-SIG, which offers loads of information about compatibility & community support.
And if you’re trying lớn master all things PCIe, it won’t hurt khổng lồ learn more about motherboards, too. Be sure lớn check out our article titled What Does a Motherboard Do? for a comprehensive sầu guide on this piece of tech. Then, you can read through our guide on How lớn Choose a Motherboard for shopping tips.
