Best Flagship1 of 6
MSI MPG X870E Carbon WiFi on Amazon (opens in a new tab)
The X870E Carbon pairs USB4 and Wi-Fi 7 with PCIe 5.0 graphics and M.2 slots.
Best for
- Creators who game.
Skip if
- Skip it if you need to know its M.2 slot count before buying; the maker doesn't publish one.
Why we like it
It has dual LAN and an EZ PCIe release button, and a heat-piped VRM heatsink with 7W/mK pads keeps the power stage cool. It also comes with Bluetooth 5 alongside Wi-Fi 7. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback.
When we checked, only the Strix X670E-A and cheaper picks cost less, and the Strix X870E-E cost more. If you want a confirmed M.2 slot count, look to the Strix X870E-E instead: it offers 5, while this one gives no figure.
Key dimensions & specs
- Wi-Fi: Wi-Fi 7
- USB4: Yes
- Form factor: ATX
- Socket: AM5
Pros
- Wi-Fi 7 built in
- USB4 ports on the rear panel
- PCIe 5.0 graphics and M.2 Gen5 slots
- Bluetooth 5 alongside Wi-Fi 7
Cons
- No published M.2 slot count
- No published wired network speed
- Costs more than the X870 AORUS Elite at the time of writing
Solid Alternative2 of 6
ASUS ROG Strix X870E-E Gaming WiFi on Amazon (opens in a new tab)
The Strix X870E-E offers five M.2 slots, an 18+2+2 layout and USB4.
Best for
- Buyers who want 5 m.2 slots for ssd expansion.
Skip if
- Pass if a published wired network speed matters; this one has none.
Why we like it
It is ASUS's high-end AM5 board here. Nothing else here matches its 5 M.2 slot count; the X870 AORUS Elite comes closest at 4. No other pick in this guide offers 18+2+2 power stages; compare the Strix B850-A, which has 14+2+2 power stages.
You also get a rear USB 20Gbps port alongside USB4. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all.
Only the X870E Carbon came close to it on price at the time of writing; it cost the most of the 6 picks. There is no published wired network speed figure, whereas the B850 Tomahawk MAX offers 5Gbps.
Key dimensions & specs
- M.2 slots: 5
- Wi-Fi: Wi-Fi 7

Longest Warranty3 of 6
GIGABYTE X870 AORUS Elite WIFI7 on Amazon (opens in a new tab)
The X870 AORUS Elite pairs four M.2 slots and USB4 with Gigabyte's five-year warranty.
Best for
- Long-term builds.
Skip if
- Skip it if this is a deal-breaker for you: m.2 slot count of 4, behind the Strix X870E-E (5).
Why we like it
It is the X870 board with the longest cover here. On M.2 slot count it ties with the Strix B850-A, the Strix X670E-A and the B850 Tomahawk MAX at 4. On wired network speed it ties with the Strix B850-A at 2.5Gbps.
You also get EZ-Latch for tool-free card removal and a PCIe 5.0 graphics slot. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all.
It was the cheapest of the group when we checked; the Strix B850-A was the next step up. The main gap: M.2 slot count of 4, behind the Strix X870E-E (5). If that matters, the Strix X870E-E offers 5.
Key dimensions & specs

Best for
- Buyers who want 4 m.2 slots for ssd expansion.
Skip if
- Skip it if wired network speed matters most to you; the B850 Tomahawk MAX offers 5Gbps.
Why we like it
Its 14+2+2 VRM is rated at 80A per stage, and heatsinks bridge to the VRMs with thermal pads. ASUS AI Advisor simplifies setup. It matches the X870 AORUS Elite, the Strix X670E-A and the B850 Tomahawk MAX on M.2 slot count (4).
It matches the X870 AORUS Elite on wired network speed (2.5Gbps). No other pick in this guide offers 14+2+2 power stages; compare the Strix X870E-E, which has 18+2+2 power stages. It also offers a rear USB 20Gbps port.
It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. It was priced above the X870 AORUS Elite and below the B850 Tomahawk MAX at the time of writing. It gives ground on wired network speed, where the B850 Tomahawk MAX offers 5Gbps.

How We Chose These Ryzen 9 7950X3D Motherboards
Each pick was assessed across 4 criteria weighted for real-world use.
- Connectivity
- We compared Wi-Fi, wired LAN speed and USB4.
- Power delivery
- We noted power stage layouts where the maker lists them.
- Platform
- We checked socket, chipset and form factor from each listing.
- Storage
- We counted listed M.2 slots and PCIe 5.0 support.
What to Look for in a Ryzen 9 7950X3D Motherboard
Key buying criteria so you get the right fit the first time.
Count M.2 slots
Most games now install to NVMe drives. Count how many M.2 slots you need now and later, and check which ones share lanes with other ports.
Check the rear and front I/O
Count USB ports you use every day and confirm a front USB-C header if your case has a USB-C port.
Match the chipset to your plans
On AM5, B850 covers most gaming builds with PCIe 5.0 for at least one slot. X870E adds more PCIe 5.0 lanes and USB4 for heavy expansion.
Features, not frame rates, separate the chipsets.
Check BIOS support and Flashback
A board may need a BIOS update before it runs a newer CPU. BIOS Flashback lets you update without a working CPU installed.
Power delivery for high-end CPUs
Boards with more and stronger power stages run hot 16-core chips more comfortably. For eight-core gaming CPUs, most current boards are enough.
Networking matters for daily use
Wi-Fi 7 and 5Gbps Ethernet help only if your router supports them, but built-in Wi-Fi saves a PCIe card.

Frequently Asked Questions
Do I need X870E for gaming?
No. A B850 board runs the same CPUs at the same speed; X870E adds more PCIe 5.0 lanes, USB4 and expansion.
Do I need PCIe 5.0?
Current graphics cards barely benefit. PCIe 5.0 matters more for the fastest SSDs.
What size motherboard should I buy?
ATX fits most mid-towers and has the most slots. Micro-ATX and Mini-ITX suit smaller cases with fewer expansion needs.
Will a new board work with my CPU out of the box?
Usually, but check the board's CPU support list. If your chip needs a newer BIOS, BIOS Flashback updates it from a USB drive.
Is built-in Wi-Fi worth it?
Yes if you cannot run a cable. Otherwise wired Ethernet is more consistent.
Should I fill all four memory slots?
Two sticks usually run faster and more reliably on DDR5. Buy a two-stick kit with the capacity you need.
Bottom Line
The X870E Carbon and Strix X870E-E suit a flagship build. The X870 AORUS Elite adds a five-year warranty, and the B850 Tomahawk MAX keeps costs down.
