PCIe 4.0 is a relatively new technology, and as such, there are currently only a few laptops that support it. Here are a few examples of PCIe 4.0 laptops that are currently available or will be available soon:
AMD Ryzen-based laptops: Some of the newer models of laptops based on AMD Ryzen processors, such as the Ryzen 9 5900HX and Ryzen 9 5980HS, support PCIe 4.0. These laptops are suitable for gaming, video editing, and other demanding workloads.
Dell Alienware m15 R6/R7: These high-end gaming laptops are based on Intel Core processors and support PCIe 4.0 NVMe SSDs.
ASUS ROG Zephyrus G15: this laptop models features an AMD Ryzen 9 processor and an NVIDIA GeForce RTX 3080 graphics card, the laptop supports PCIe 4.0 NVMe SSDs
MSI GE76 Raider: Another Gaming Laptop supports PCIe 4.0 NVMe SSDs and an Intel Core i9 processor.
Alienware m17 R5: This is another high-end gaming laptop that supports PCIe 4.0 NVMe SSDs, it is powered by Intel Core processors.
AMD Ryzen-based desktops: Some of the newer models of desktops based on AMD Ryzen processors, such as Ryzen 9 5900X, Ryzen 9 5950X, Ryzen 7 5800X and Ryzen 7 5700X support PCIe 4.0. These desktops are suitable for gaming, video editing, and other demanding workloads.
ASUS ROG Maximus XII Hero Z490: This high-end motherboard supports Intel Core processors and features PCIe 4.0 support for NVMe SSDs.
ASRock X570 Taichi: A motherboard that supports PCIe 4.0 and works with AMD Ryzen processors.
Gigabyte AORUS X570 Master: Another motherboard that supports PCIe 4.0 and works with AMD Ryzen processors
MSI MPG B550 Gaming Edge WiFi: A PCIe 4.0 motherboard that works with AMD Ryzen processors
It’s worth noting that in order to take advantage of the faster speeds of PCIe 4.0, both the device (SSD) and the motherboard should support it, so its important to check the specifications of the laptop prior to purchase. Also, while the availability of PCIe 4.0 laptops is limited currently, it’s expected that more models will be released over time.
When comparing the mentioned laptops, it’s important to consider not only the fact that they support PCIe 4.0 but also other factors such as performance, display, graphics card, battery life, build quality and also the price. Most of these laptops are high-end models and may be expensive.
It’s important to keep in mind that, while PCIe 4.0 is faster than PCIe 3.0, it is not always necessary to have the latest technology to run things smoothly. An NVMe SSD using PCIe 3.0 can still deliver a significant performance boost over traditional hard drives, whether you are running a program, storing or retrieving a big file, and you may want to consider that before jumping on the latest technology.
PCIe 4.0 technology
PCIe 4.0 (Peripheral Component Interconnect Express 4.0) is the fourth generation of the PCIe interface, which is used to connect devices such as graphics cards, solid-state drives (SSDs), and network cards to a computer’s motherboard. Compared to its predecessor, PCIe 3.0, PCIe 4.0 offers several key improvements:
Increased Bandwidth: PCIe 4.0 has a maximum transfer rate of 16 GT/s (gigatransfers per second), which is double the 8 GT/s of PCIe 3.0. This means that devices connected to a PCIe 4.0 interface can transfer data at much faster rates, resulting in improved performance for tasks such as gaming, video editing, and data analysis.
Lower Latency: Due to the increased bandwidth, there is a reduction in the amount of time it takes for data to travel between the device and the CPU, which means lower latency. This is particularly beneficial for real-time applications such as gaming and virtual reality.
Increased Power Efficiency: PCIe 4.0 uses less power than PCIe 3.0, which can help to extend battery life in mobile devices.
Improved Encryption: PCIe 4.0 includes improved encryption for enhanced security.
It’s worth noting that in order to take advantage of the faster speeds of PCIe 4.0, both the device and the motherboard must support it, So it’s not only the peripherals that need to support PCIe 4.0, but also the motherboard, CPU, and the bios also. Also, while PCIe 4.0 is an improvement over PCIe 3.0, it’s not required to have the newest technology to be able to run things smoothly, it’s mostly relevant to those who demand the highest performance on their systems.
Overall, PCIe 4.0 is an exciting new technology that promises to improve the performance of computers and other devices. However, it is still in the early stages of adoption and may not be widely available for some time. For now, you can look out for compatible devices, such as NVMe SSDs, that are already starting to come out in the market, and expect more to come out in the near future.
