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 is expected to release in September, 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.

The W680 and Q670 chipsets are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

MOTHERBOARD The motherboard must support overclocking to use overclocking capabilities. Motherboards with Z-prefixed chipsets more commonly support overclocking.

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 UDIMMs (128 GB vs. 32 GB).

DDR5 may experience slower timings at initial release but should be much better than DDR4 as the technology matures. However, keep in mind that the timings scale inversely with the clock rate (frequency). The timing values are in units of clock cycles, but more cycles are happening per second with DDR5. For example, DDR3-2133 CL10 has nearly the same latency as DDR5-8400 CL40. So don't let the CL40 timings of DDR5 scare you away; the number just looks bigger!

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.

Before purchasing memory, review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. Motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.

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 lane 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.

AMD's Zen 4-based Ryzen 7000 desktop CPUs will be their first to support PCIe 5.0. The Ryzen 7000 CPUs aren't expected to be available until September 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.
