Intel Motherboard buyers guide
How to choose an Intel motherboard
If the CPU is the brain of the PC, then the motherboard is like the nervous system, connecting all the other components together, such as the GRAPHICS CARD , memory and drives, enabling them to communicate with one another.
Just like with any component you need to make sure that you choose a motherboard that is compatible with your CPU. In this guide, we will be focussing our attention on motherboards for INTEL PROCESSORS .
Three main factors
There are three main factors to consider when choosing a new motherboard, the socket, the chipset and the size. You can see each of these three characteristics listed on the motherboard homepage on the Scan website and this guide will explain what you need to look out for.
1 Socket
2 Chipset
3 Size
Motherboard Sockets
The first thing to look out for is the socket, which is where the CPU physically connects to the motherboard. CPUs are available in all sorts of shapes and sizes, each with their own socket, so it’s critically important to make sure that the socket of the CPU and motherboard is the same. While Intel does change the socket design from time to time when designing new CPUs, most current Intel CPUs fall into five main sockets: Socket 1700, Socket 1200, Socket 2066, Socket 3647 and Socket 4189, where the number refers to the quantity of electrical connecting pins in the socket.
Motherboard Chipsets
After checking the socket type you also need to consider the chipset. The chipset determines a lot of the capabilities of the motherboard, such as the number of add-in cards, the number of memory slots and USB ports. Some CPUs are only served by one chipset while other times you have a choice of chipsets, so you can strike the right balance between features and budget.
Motherboard Size
The last thing you need to consider when choosing a new motherboard is the size. Size is important because you need to make sure that the motherboard you buy can fit in your
CASE
. Larger motherboards are beneficial because they support more add-in cards and memory, but you can still build very capable and high performance systems with smaller motherboards.
The computer industry uses codenames to refer to the size of the motherboard, but the good news is that those same codenames are used for the size of cases too. This diagram illustrates the dimensions of the most common motherboard sizes.
| Mini-ITX | Micro-ATX | ATX | E-ATX SSI-EEB |
|---|---|---|---|
| 170 x 170 mm | 244 x 244 mm | 305 x 244 mm | 305 x 330 mm |
Socket 1700 Motherboards
Socket 1700 motherboards support the latest Intel 14th gen Core CPUs based on the Raptor Lake Refresh architecture plus older Intel 13th gen and 12th CPUs based on the Raptor Lake and Alder Lake architectures respectively.
LATEST SUPPORTED CPU ARCHITECTURE 14th gen, Raptor Lake Refresh
RAPTOR LAKE REFRESH MOTHERBOARD CHIPSETS
Z790 and Z690 are the two high-end motherboard chipsets for Intel 14th, 13th and 12th gen Core CPUs. Z790 supports the most PCIe 4.0 lanes and USB ports while Z690 provides less.
H770 and B760 are the two mid-range motherboard chipsets for Intel 14th, 13th and 12th gen Core CPUs. H770 supports the most PCIe lanes and USB ports and is intended for home PCs, while B760 supports fewer PCIe lanes and USB ports and is intended for office PCs.
H610 is the entry-level motherboard chipset for Intel 14th, 13th and 12th gen CPUs and therefore supports the least number of PCIe lanes and USB ports.
Socket 1200 Motherboards
Socket 1200 motherboards support Intel 11th gen and 10th Core CPUs based on the Rocket Lake and Comet Lake architectures respectively. Make sure to choose one of the newer 500-series chipset motherboards to enable PCIe 4.0 support.
LATEST SUPPORTED CPU ARCHITECTURE 11th gen, Rocket Lake
ROCKET LAKE MOTHERBOARD CHIPSETS
Z590 is the flagship motherboard chipset for Intel 11th gen Core CPUs, supporting the most PCIe lanes and USB ports.
H570 and B560 are the two mid-range motherboard chipsets for Intel 11th gen Core CPUs. H570 supports the most PCIe lanes and USB ports and is intended for home PCs, while B560 supports fewer PCIe lanes and USB ports and is intended for office PCs.
H510 is the entry-level motherboard chipset for Intel 11th and 10th gen CPUs and therefore supports the least number of PCIe lanes and USB ports.
Socket 2066 Motherboards
Socket 2066 motherboards support older Core i9 X-Series CPUs based on the Cascade Lake X architecture plus Xeon W workstation CPUs based on the Cascade Lake W architecture.
LATEST SUPPORTED CPU ARCHITECTURE 10th gen, Cascade Lake X and W
CASCADE LAKE MOTHERBOARD CHIPSETS
X299 is the only motherboard chipset for Core i9 X-series CPUs.
C422 is the only motherboard chipset for Cascade Lake W Xeon W-series CPUs.
Socket 3647 Motherboards
Socket 3647 motherboards support 1st and 2nd gen Xeon Scalable processors based on the Skylake SP and Cascade Lake SP architectures. These motherboards are commonly used in servers and ultra-high-end workstations. Most, but not all Socket 3647 motherboards support two CPUs working together in parallel for even greater performance.
