Motherboard 2026: which chipset to choose (AMD and Intel) and 3 AM5 boards at the best price

A motherboard does not make your PC faster on its own: it decides which CPUs, which RAM, how many SSDs and which upgrades your PC can take. In 2026 the choice almost always comes down to two platforms: AMD AM5 (Ryzen 7000, 8000G and 9000) and Intel LGA1851 (Core Ultra 200S).

If you want the quick version:

• AMD gaming PC (the most common case): a B850, which guarantees a PCIe 5.0 M.2 slot and allows overclocking.
• Tight AM5 budget: a B650 is still fine as long as you check the number of M.2 slots and Wi-Fi.
• Guaranteed USB4 and a PCIe 5.0 graphics slot: step up to X870 (or X870E for more connectivity).
• Intel Core Ultra 200S: a B860 is enough if you do not overclock the CPU; Z890 only makes sense for a “K” CPU you want to push.
• Avoid for a gaming PC: A620, B840 and H810, which are too limited (no CPU overclocking, and no memory overclocking at all on H810).

Looking for picks by use case (gaming, ITX, high end)? See our best gaming motherboard guide. This page helps you understand what you are buying.

The motherboard connects everything: the processor sits in its socket, the RAM in its DIMM slots, the graphics card in the PCIe x16 slot and your SSDs in the M.2 or SATA ports.

In practice it determines:

• Compatibility: CPU socket and memory type (DDR5 only on AM5 and LGA1851).
• Upgradability: number of M.2 slots, PCIe generation, number of fast USB ports.
• Stability: quality of the power stage (VRM) and its cooling, especially with a high-end CPU.
• Connectivity: Wi-Fi, Bluetooth, 2.5 GbE or 5 GbE networking, audio, front USB-C.

In games, two boards with the same chipset deliver almost identical FPS with the same CPU and GPU. The difference is features and platform lifespan, not raw performance.

Every AM5 chipset supports Ryzen 7000, 8000G and 9000, DDR5 only, with EXPO profiles. What changes: CPU overclocking, PCIe generation and USB4 (AMD specifications).

On Intel, the 800 series (Z890, B860, H810) pairs with Core Ultra 200S. The rule is simple: only Z890 lets you overclock the CPU, B860 keeps memory overclocking (XMP profiles), and H810 allows neither, with one module per channel (so two RAM slots at most).

• B850 and B840 have joined the AM5 line-up since 2025: at a price close to a B650, a B850 adds a guaranteed PCIe 5.0 M.2 slot.
• X870 and X870E are the only AM5 boards with mandatory USB4. If you have no USB4 or Thunderbolt device, a B850 is enough.
• On Intel, B860 and H810 complement Z890, which launched first. For an Intel gaming PC without overclocking, B860 is the logical pick.
• Z990 boards (Nova Lake, LGA1954) are not an option yet: they only appear in leaks and shipping records, with no official price or release date.
• AM5 keeps an upgrade advantage: the same board accepts Ryzen 7000, 8000G and 9000, as long as you update the BIOS.

Three boards from our catalog, one per chipset. Prices are the best US offer listed on DropReference product pages on October 11, 2026; when a board has no US listing we say so instead of converting a European price. Open a product page for live prices.

AM5 for Ryzen 7000 to 9000, LGA1851 for Core Ultra 200S. On AM5, check that the board supports your CPU out of the box or offers a BIOS update without a CPU (BIOS Flashback).

Two M.2 slots is the minimum in 2026, three is comfortable. A single PCIe 5.0 M.2 slot is plenty: in games, a PCIe 4.0 SSD is almost as fast.

Four DDR5 slots to keep room for upgrades, and EXPO (AMD) or XMP (Intel) support to run your kit at its rated speed, for example DDR5-6000 on AM5.

With a Ryzen 7 or Core Ultra 7, any recent B850 or B860 will do. For a Ryzen 9 or Core Ultra 9 under heavy load, choose a mid-range board with proper VRM heatsinks.

Wi-Fi 6E or 7 if you are not wired, 2.5 GbE networking, at least one front USB-C and enough rear USB ports for your peripherals.

ATX for most cases, micro-ATX to save a little, mini-ITX only for a compact PC (fewer M.2 slots and ports).

ASUS, MSI, Gigabyte and ASRock all make reliable AM5 and LGA1851 boards. At the same price, compare the spec sheets rather than the logo:

• ASUS: Prime (essentials), TUF Gaming (rugged) and ROG Strix (high end).
• MSI: Pro, MAG (including the well-known Tomahawk) and MPG.
• Gigabyte: Eagle, Gaming and Aorus.
• ASRock: Pro RS, Steel Legend and Taichi, often competitively priced.

The right approach: pick the chipset and must-have features first (M.2 count, Wi-Fi, USB), then buy the cheapest board that ticks every box.

In 2026, B850 is the default choice for an AMD gaming PC and B860 for an Intel PC without overclocking. Only step up to X870 or Z890 if you will use what they add.

Motherboard prices vary from one retailer to another: DropReference compares offers in real time, and the PC builder checks compatibility between your motherboard, CPU and RAM.

A B850: overclocking enabled, guaranteed PCIe 5.0 M.2 and a price close to B650. X870 only adds USB4 and a guaranteed PCIe 5.0 graphics slot, with no FPS gain.

B860 if your CPU is not a “K” model or you will not overclock it: it keeps memory overclocking (XMP). Z890 is only useful for CPU overclocking or if you need lots of M.2 and USB.

Yes, if it is clearly cheaper than an equivalent B850 and has enough M.2 slots for you. Otherwise, the B850 is more future-proof.

Not if you need to buy now: they are only known from leaks, with no official price or release date, and they will require new CPUs.

Very little. With the same CPU, RAM and graphics card, the differences between boards with the same chipset are negligible in games.
