Which AMD Graphics Cards Support PCIe 4.0?

Section Link

All graphics cards with AMD's Radeon RX 5000 and Radeon RX 6000 series GPUs support PCIe 4.0.

Newer graphics card prices are inflated by about 100% of MSRP due to various factors, including chip shortages triggered by the pandemic and high demand from crypto miners and holiday shoppers.

Chipmakers indicate that chip shortages could last into at least the end of 2022, so plan accordingly.

If you are considering upgrading, you may be able to save a little by selling your old graphics card at inflated prices.

PCIe 4.0 Benefits

Section Link

Bandwidth

The key benefit of upgrading to PCI-Express 4.0 is the increased bandwidth. Each version of PCIe roughly doubles the bandwidth available per lane.

PCI-Express 4.0 vs. 3.0 Speeds (Rounded)
PCIe 3.0PCIe 4.0
x1 Bandwidth 1 GB/s 2 GB/s
x2 Bandwidth 2 GB/s 4 GB/s
x4 Bandwidth 4 GB/s 8 GB/s
x8 Bandwidth 8 GB/s 16 GB/s
x16 Bandwidth 16 GB/s 32 GB/s

Any devices which were designed for PCIe 4.0 can benefit from the increase in available bandwidth.

Devices designed for PCIe 4.0 could mean faster storage speeds (video and game loading) and faster graphics (video games and rendering).

However, some devices may not even be reaching the limits of PCIe 3.0 yet. The low bandwidth usage by some devices means that it's only necessary to upgrade if:

  • You are using the latest and fastest storage devices and video cards, which make use of the PCIe 4.0 lanes.
  • You want to free up PCIe lanes by using PCIe 4.0 devices, which won't need as many lanes for the same bandwidth.
  • You want to future-proof your system.

Storage

The component which can benefit the most from PCIe 4.0 is NVMe storage. The latest top-performing NVMe SDD and add-in card (AIC) storage devices can benefit from both the higher throughput and the throughput available per lane.

Lanes

With each PCIe version doubling the bandwidth per lane, newer devices can reduce the number of needed lanes. For example, if even the top tier of graphics cards no longer need the full 16 lanes to meet their needs, they can use 8 or fewer lanes. By using fewer lanes, it frees up more lanes for other devices. Using fewer lanes is important because CPUs provide a limited number of lanes, which need to be distributed among the devices.

The same is valid for storage. If your storage devices no longer need as many lanes, PCIe add-in card (AIC) adapters can connect more NVMe M.2 SSDs.

For networking, a single lane could now provide enough bandwidth for 10 Gbps Ethernet.

Future-Proofing

If you are building a new system, it may make sense to do the upgrade to 4.0. In particular, future graphics cards and storage devices may further take advantage of this available bandwidth. In this case, you might consider how long you plan to use this computer. For example, will you upgrade your storage and graphics card over the next few years or wait to replace the entire system?

Is PCIe 4.0 Worth It for Gaming?

Section Link

It is worth the upgrade to PCIe 4.0 for gaming if you:

  • Use the fastest NVMe storage devices for loading games, which will make use of the speed
  • Have a PCIe 4.0 graphics card, which may see a slight performance improvement
  • Want to future-proof your system
  • Want to free up PCIe lanes for other devices

What Is the Latest Version of PCI-Express?

Section Link

The latest available version of PCI-Express is PCIe 5.0. PCIe 5.0 CPUs are available from Intel, while AMD currently only supports PCIe 4.0.

Intel's 12th generation Core CPUs currently provide PCIe 5.0 support for CPU lanes (i.e., one to two PCIe slots) and PCIe 4.0/3.0 speeds for the remaining lanes.

The first AMD CPUs that support PCIe 5.0 aren't expected to be available until 2022.

PCIe versions such as 3.0, 4.0, and 5.0 are sometimes informally referred to as PCIe Gen 3, PCIe Gen 4, and PCIe Gen 5. This naming is based on them being the third, fourth, and fifth generations of PCI-Express.

PCIe 5.0 graphics cards and storage devices are not currently on the market.
