Perhaps you are upgrading to a new computer and want to know which motherboards will work with the latest generation of CPUs. Or maybe you want to know which devices are available that support PCIe 5.0. In this article, we'll fill you in on the details for future-proofing your system to support PCIe 5.0 speeds.

Which Motherboards Support PCIe 5.0?

Section Link

Intel's 12th generation Core processors, code-named "Alder Lake," support PCIe 5.0. Intel 12th Gen Core CPUs use an LGA 1700 socket.

AMD has not yet released its PCIe 5.0 processors but is expected to include PCIe 5.0 support in their next-generation Zen 4 architecture, which AMD will release in 2022.

For 12th Gen Intel CPUs, PCIe 5.0 support means either one x16 or two x8 PCIe slots can run at PCIe 5.0 speeds for graphics or storage purposes. The CPUs provide four additional PCIe 4.0 lanes (e.g., an x4 slot) that you can only use for storage devices.

For compatibility with Intel's 12th Gen Core CPUs, you'll need to use a motherboard with a Z690, H670, B660, or H610 chipset. Motherboards with the Z690 chipset were the first ones available, while motherboards with the other chipsets are starting to be released in early 2022.

Intel 600 Series Desktop Chipsets
Z690H670B660H610
Release Date Q4 2021 Q1 2022 Q1 2022 Q1 2022
CPU Overclocking Yes No No No
PCIe 5.0 Slots via Processor One x16 or Two x8 One x16 or Two x8 One x16 One x16
PCIe 4.0 Slots via Processor One x4 One x4 One x4 None
PCIe 4.0 Lanes via Chipset Up to 12 Up to 12 Up to 6 None
PCIe 3.0 Lanes via Chipset Up to 16 Up to 12 Up to 8 8
Memory Overclocking Yes Yes Yes Yes
Memory Channels 2 2 2 1
DMI 4.0 Lanes 8 8 4 4
USB 3.2 Gen 2x2 (20 Gbps) Up to 4 Up to 2 Up to 2 None
USB 3.2 Gen 2x1 (10 Gbps) Up to 10 Up to 4 Up to 4 Up to 2
USB 3.2 Gen 1x1 (5 Gbps) Up to 10 Up to 8 Up to 6 Up to 4
USB 2.0 Ports 14 14 12 10
Wi-Fi 6E Yes Yes Yes Yes
SATA 3.0 Ports Up to 8 Up to 8 Up to 4 4
PCIe RAID 0,1,5 Support Yes Yes No No

Note that the chipsets don't provide PCIe 5.0 lanes for M.2 storage devices. PCIe 5.0 is only available for the PCI-Express slots connected directly to the CPU. However, the chipsets do use a new DMI 4.0 link which is twice as fast as the 3.0 link used by the 500-series chipsets.

DDR4 or DDR5 Memory

Section Link

Because DDR4 and DDR5 are not backward or forward compatible, you must decide which one you want to go with before selecting a motherboard.

DDR5 memory is currently more expensive than DDR4.

However, it offers up to double the stock data rates of DDR4. Overclockers could push this limit even further.

Additionally, DDR5 supports higher-capacity DIMMs (128 GB vs. 64 GB).

DDR5 may experience slower timings at initial release but should be much better than DDR4 as the technology matures.

DDR5 memory appears to be out of stock at most retailers, so I recommend sticking with DDR4 or preparing for a long wait.

Intel's 12th generation Core CPU uses an LGA 1700 socket.

Locked Intel CPUs may come with a stock CPU cooler. These CPU models do not have a "K" in the name. While stock coolers will prevent your CPU from overheating, your CPU will throttle its performance during games and other intensive tasks. Higher TDP coolers will keep your CPU at turbo speeds for longer durations. Stock coolers are often quite loud at their maximum speed.

The LGA 1700 socket will require a CPU cooler that supports the new socket size. Some manufacturers are releasing upgrade kits for LGA 1200 heatsinks to support the new size.

Best AIO Liquid Cooler: Enermax Liqmax III 360

  • This Enermax liquid cooler has an excellent cooling capability with a 360-watt TDP (Thermal Design Power).

  • Quiet operation at 14-27 dBA.
  • You can request an LGA 1700 mounting kit via the LGA 1700 Mounting Kit Request Form.

How Fast Is PCIe 5.0?

Section Link

PCI-Express speeds are based on the PCI-Express version and the number of lanes used. One line is referred to as x1, two lanes as x2, etc. PCI-Express technically supports up to a width of x32. However, most consumer motherboards have some set of these PCIe widths: x1, x2, x4, x8, x16.

PCI-Express Speeds (Rounded)
PCIe 4.0PCIe 5.0
x1 Bandwidth 2 GB/s 4 GB/s
x2 Bandwidth 4 GB/s 8 GB/s
x4 Bandwidth 8 GB/s 16 GB/s
x8 Bandwidth 16 GB/s 32 GB/s
x16 Bandwidth 32 GB/s 63 GB/s

Intel's 12th generation CPUs currently provide PCIe 5.0 support for CPU lanes (i.e., one x16 or two x8 PCIe slots) and PCIe 4.0/3.0 speeds for the remaining lanes.

The bandwidth for each PCIe 5.0 lane is 4 GB/s. 4 GB/s per lane means that if you use a PCI-Express 5.0 x16 device, it would have up to 64 GB/s of bandwidth available to it.

NVMe M.2 SSD cards use 2 or 4 lanes, which means they have 4–8 GB/s available to them with PCIe 4.0.

NVMe PCIe add-in cards can use up to 16 lanes in an x16 slot, thus having up to 32 GB/s of bandwidth available to them with PCIe 4.0.

In comparison, PCIe 3.0 has half of the bandwidth of PCIe 4.0.

PCI-Express 3.0 Speed (Rounded)
x1 Bandwidth 1 GB/s
x2 Bandwidth 2 GB/s
x4 Bandwidth 4 GB/s
x8 Bandwidth 8 GB/s
x16 Bandwidth 16 GB/s

What Is the Latest Version of PCI-Express Available in CPUs?

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 x16 or two x8 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.
