Intel’s latest CPUs are the ‘Alder Lake’ 12th Generation, and they’re a sea-change in design and implementation. In this article we’ll discuss some of the factors you’ll need to consider when choosing a motherboard, and show you our current choices for the best options across a range of budgets and purposes for the i5-12900K.

The Alder Lake CPUs mark Intels first wholly new architecture in years, and also a move to a more efficient 10nm production process. High-end Alder Lake CPUs use two distinct kinds of cores: high performance ‘P’ Cores alongside more efficient ‘E’ Cores, to allow background or system workloads to be appropriately handled without impacting the performance of primary tasks. They’ve combined these advantages with a shift to DDR5 RAM compatibility to make a platform that moves CPUs on a generation.

With these improvements comes a raft of complexity if you’re just looking to build the best PC for your money right now. Is DDR4 RAM adequate or do you need DDR5 RAM to properly benefit from a 12th Gen CPU? What properties of a motherboard are vital, and which don’t matter? We’re here to guide you through that.


Chipset

The 12900K should be paired with a Z690 motherboard.

Alder Lake CPUs use the new LGA 1700 Socket from intel, which is slightly larger than existing sockets. You’ll find these sockets on the newly released Z690 motherboards, as well as upcoming B660 and H670 motherboards. Because the K series 12900K CPU is overclockable and has both P and e cores, you’ll want to pair it with a Z690 motherboard to ensure you are able to extract the maximum potential from this high-performance CPU. They’re also the only motherboards currently available, so if you want to get your Alder lake System off the ground now, you’ll need to choose Z690.

DDR4 vs DDR5

DDR4 is the sensible option but DDR5 may offer higher ultimate performance.

One of the first considerations when choosing a Z690 motherboard is whether you will use DDR4 RAM or DDR5. Alder Lake 12th Gen CPUs can use either, but the motherboard dictates which you will use and they are not cross-compatible. DDR5 is the latest specification and boasts impressive headline speeds but in fact, there’s a lot more to RAM performance than advertised Speed in MHz. Whilst DDR5 has the edge in bandwidth, good DDR4 kits still perform better particularly in games due to lower latencies. DDR5 is also very hard to find, and currently expensive. Whilst we expect DDR5 to develop into the standard option over the next year or so, particularly with AMD’s next-generation Ryzen CPUs using it as well, right now DDR4 is the sensible option for building a 12th generation Intel-based PC. If cost is no object and you want to use RAM with the best possible performance particularly in memory heavy tasks, thenDDR5 may be the better option for you, but we expect the situation to improve as more DDR5 kits become available, and speeds and specification increase.

We’ll develop and deliver more content on this as we’re able to test more but independent reviewers such as Gamers Nexus and Techpowerup have verified the performance of DDR4 except in certain specific non-gaming tasks where the bandwidth of DDR5 is an advantage. You’ll need to check the name or the specification of the board you’re buying to verify that it’s compatible with the RAM type you’ve chosen.

Features

When choosing a motherboard, there’s a number of features you’ll want to consider to ensure it provides a good basis for your PC. Voltage Delivery is an important factor for Intel CPUs which remain relatively power-hungry. However, for Z690 manufacturers have largely provided good solutions that are capable of running even a 16 core 12900K to full potential. We’d just caution against entry-level motherboards for the i9-12900K that lack basic heat sinks on the VRM, as that’s a sign that cost-cutting has taken precedence.

After that, it’s just a case of finding a board with the right number of input and output options for you, as the base specifications across all Z690 motherboards are very similar. Consider if you want WiFi Inbuilt, how many USB ports you’re likely to need and what speed they should be, and how many M.2 and PCIe slots you require.

All of our recommended motherboards below combine rock-solid specifications with a feature set that will get the best out of your flagship powered PC, so let’s dig in and find some motherboards that will give you the very best i9-12900K PC possible!
