How Many PCI-E Lanes Does Ryzen Have

AMD and Intel have been going head to head for several years, with both companies releasing new CPU architectures and products to compete against each other.

Ryzen is AMD’s latest release, aimed at gamers and streamers who need some serious power from their PC. But how does it compare to Intel? Find out in this article!

How Many PCI-E Lanes Does Ryzen Have?

Ryzen comes with a total of 20 PCIe lanes. Sixteen belong to the CPU, while the chipset provides the other four. This is double the amount of PCIe lanes that Intel’s CPUs have, which is great news for anyone looking to build a high-end PC. 

It’s important to note that not all PCIe lanes are used for graphics cards. The CPU can only use 8 of them for that purpose, while the other eight are dedicated to M.2 slots and other devices. The chipset also provides four additional lanes for SATA ports and USB 3.0.

Why is Ryzen Important?

Ryzen is important because it is a new CPU architecture that significantly improves performance over the previous generation.

It is also more power efficient, which means that it will generate less heat and require less cooling. Additionally, Ryzen CPUs offer more memory and I/O bandwidth than their predecessors.

Can You Preorder Yours Today?

Yes, you can preorder your Ryzen processor today. There are a few different ways to do this. You can either order online or through a retailer. If you order online, you must select a retailer that offers preorders.

Some of the most popular retailers that offer preorders are Amazon, Newegg, and Best Buy. If you order through a retailer, you will need to find a store that offers preorders. You can check with your local computer store or electronics store to see if they offer preorders.

What are the benefits of having more PCI-E lanes?

PCI Express (PCIe) is a computer expansion card standard that enables faster data transfers and provides more bandwidth than earlier standards like PCI and AGP. PCIe has numerous benefits over its predecessors.

One of the most noticeable benefits is increased data transfer speed. PCIe 2.0 has a maximum data transfer rate of 5 Gbps, while PCIe 3.0 can reach 8 Gbps. That’s more than twice the speed of PCI or AGP!

But data transfer speed is not the only improvement with PCIe. The number of lanes on a PCIe card also determines how much bandwidth is available. A “lane†is a single signal-carrying wire pair, so an x1 card has one lane, an x4 card has four lanes, etc.

Increasing the number of lanes also increases the amount of available Bandwidth. So, for example, an x16 card has 16 lanes and can provide up to 128 Gbps of bandwidth, while an x4 card is limited to 32 Gbps.

This is why graphics cards and other high-performance devices typically use x16 cards – they need all the bandwidth they can get!

When and Where Can I Buy Ryzen Processors?

Ryzen processors are available for purchase from various online and offline retailers. Regarding online retailers, Amazon and Newegg are two of the most popular choices. As for offline retailers, Best Buy and Micro Center are two examples.

When it comes to price, Ryzen processors are very competitively priced. For example, the AMD Ryzen 7 1700X can be found for around USD 330.

Specifics of the AMD Ryzen 1700X

The AMD Ryzen 1700X is a high-end desktop processor released in early 2017. It is based on the 14nm “Zen” microarchitecture and features 8 CPU cores with 16 threads.

The base clock speed of the 1700X is 3.4GHz, with a boost clock speed of 3.8GHz. The TDP (thermal design power) of the 1700X is 95W.

The 1700X has 32MB of L3 cache and supports DDR4-2400MHz memory. It includes two USB 3.1 ports, four USB 2.0 ports, and one HDMI port.

The AMD Ryzen 1700X uses the AM4 socket and is compatible with a range of aftermarket cooling solutions.

What are the downsides to having more PCI-E lanes?

The main downside to having more PCI-E lanes is the increased cost of the motherboard and processor. More PCIe lanes also require more power, leading to increased heat output. Additionally, some motherboards with many PCI-E lanes may have compatibility issues with certain graphics cards or other devices.

AMD Ryzen Processors – The Pros and Cons

When it comes to deciding which CPU is right for your needs, there are a lot of factors to consider. One important factor is the number of PCI Express (PCIe) lanes that the CPU offers. PCIe lanes connect GPUs, storage devices, and peripherals to the motherboard.

AMD’s Ryzen processors offer many PCIe lanes for most builds. However, there are pros and cons when deciding if a Ryzen processor is right for you.

Frequently Asked Questions

What is Ryzen?

Ryzen is a line of central processing units (CPUs) marketed and designed by AMD. The name derives from “Zen,” the codename used for the first generation of the Ryzen CPU.

How many PCI-E lanes does Ryzen have?

As for the number of PCI-E lanes, Ryzen has 24. This is double the number found on Intel’s Kaby Lake processors, which only have 16 lanes. As a result, you can theoretically connect twice as many devices to a Ryzen-based system.

What is the difference between Ryzen and other CPUs?

Now, let’s compare Ryzen to other CPUs on the market. Regarding raw performance, AMD’s latest CPUs are very competitive with Intel’s offerings. They offer similar levels of single-threaded and multi-threaded performance. However, where they differ is in price. AMD’s CPUs are typically much cheaper than Intel’s flagship models, making them a great option for budget-conscious consumers. 


Ryzen processors have a lot of PCIe lanes, which is great for people who want to use multiple graphics cards or other high-speed devices. However, it’s important to note that not all Ryzen processors have the same number of PCI-E lanes. So, if you’re planning on using many high-speed devices, check how many PCI-E lanes your particular processor has.
