Will PCIe 5.0 Give Graphics Cards a Boost?

If you’re into gaming or other graphics-intensive applications, you know that the speed and power of your graphics card can make all the difference. And if you’re following the latest trends in hardware, you may have heard about PCIe 5.0, the next generation of the PCI Express interface that connects your graphics card to your CPU and motherboard. But what exactly is PCIe 5.0, how does it work, and will it make your graphics card faster? Let’s find out.

What is PCIe 5.0 and How Does it Work?

PCIe, or Peripheral Component Interconnect Express, is a high-speed serial bus standard that allows devices to communicate with each other over a dedicated lane or set of lanes. PCIe was first introduced in 2003 as PCIe 1.0, with a maximum data rate of 2.5 GT/s (gigatransfers per second) per lane. Since then, PCIe has evolved through several versions, each doubling or quadrupling the transfer rate and other features such as lanes, power management, and error correction. PCIe 2.0 came out in 2007 with 5 GT/s per lane, PCIe 3.0 in 2010 with 8 GT/s per lane, and PCIe 4.0 in 2017 with 16 GT/s per lane.

PCIe 5.0, announced in 2019 and expected to debut in 2021, promises to double the transfer rate of PCIe 4.0, achieving up to 32 GT/s per lane, or 128 GB/s in a 16-lane configuration. PCIe 5.0 achieves this speed by using more advanced signaling techniques such as PAM4 (four-level pulse amplitude modulation) and FEC (forward error correction), as well as reducing the voltage from 0.8 to 0.6 volts. PCIe 5.0 also adds some new features such as DLS (dual-link signaling), which allows two lanes to act as one for higher bandwidth, and CXL (compute express link), which enables heterogeneous computing by sharing memory and cache between CPUs, GPUs, and FPGAs.

Why Would Graphics Cards Benefit from PCIe 5.0?

Graphics cards, or GPUs (graphics processing units), are among the most demanding and power-hungry devices in a PC or workstation. Graphics cards process millions of pixels, textures, and geometry data per second, and require fast access to their own memory as well as the system memory. Graphics cards also communicate with the CPU and other devices through PCIe, which serves as the main bottleneck for their performance. Therefore, any improvement in PCIe speed can potentially benefit graphics cards, especially at higher resolutions, frame rates, or workloads.

One of the ways that PCIe 5.0 can benefit graphics cards is by reducing latency. Latency refers to the time it takes for a command or data to travel from one device to another, and is usually measured in microseconds or nanoseconds. The lower the latency, the faster the response of the system to user input or events such as collisions, explosions, or user interface interactions. PCIe 5.0 can reduce latency by having faster signal transitions, less overhead, and more direct routing. This can improve the performance of graphics cards in scenarios such as real-time ray tracing or virtual reality, where low latency is critical for immersion and accuracy.

Another way that PCIe 5.0 can benefit graphics cards is by allowing more data to be transferred at once. Graphics cards need to move large amounts of data between their memory and the system memory, as well as between their processing units and the display output. This data includes textures, shaders, lighting, shadow, reflections, and many other elements that contribute to the visual quality and realism of games and other applications. PCIe 5.0 can increase the bandwidth available for these transfers, making them more efficient and faster. This can improve the performance of graphics cards in scenarios such as 4K or 8K gaming, where more data needs to be loaded and processed per frame.

Will All Graphics Cards Benefit from PCIe 5.0?

Not all graphics cards will benefit from PCIe 5.0 equally or at all. Graphics cards vary in their architecture, memory type, clock speed, and other factors that affect their performance. Graphics cards also vary in their PCIe interface, which can be PCIe 3.0 or PCIe 4.0, depending on the age and brand of the card. PCIe 5.0 is a new standard that requires both the CPU and the motherboard to support it, and currently only a few platforms offer such support, such as the upcoming Intel Alder Lake and AMD Ryzen 6000 processors, as well as some high-end motherboards from ASUS, Gigabyte, and MSI.

Therefore, to benefit from PCIe 5.0, you need to have a compatible CPU and motherboard, as well as a graphics card that can take advantage of the extra speed. This means that you need to wait for the next generation of graphics cards to come out, which are likely to support PCIe 5.0, or upgrade your existing graphics card only if you need other improvements such as more memory, more cores, or better cooling.

Moreover, even if you have a PCIe 5.0 graphics card, you need to have software that can benefit from the extra speed. Most games and applications are designed to work with PCIe 3.0 or PCIe 4.0, and may not use all the bandwidth or latency advantages of PCIe 5.0 without being updated or optimized. Therefore, the benefits of PCIe 5.0 may not be noticeable in every game or application, or may be limited by other factors such as the CPU or the display refresh rate.

Conclusion

PCIe 5.0 is the newest and fastest standard of the PCI Express interface, promising to double the transfer rate of PCIe 4.0 and bring new features such as lower voltage, better signaling, and more bandwidth. PCIe 5.0 can potentially benefit graphics cards by reducing latency and increasing bandwidth, which can improve their performance in demanding workloads or scenarios. However, only a few platforms currently support PCIe 5.0, and only the next generation of graphics cards is likely to fully take advantage of it. Therefore, while PCIe 5.0 is an exciting technology that may break speed limits, it is not yet a game changer for graphics cards, and you should consider it as part of a larger system upgrade or a future investment.
