Best Motherboard for AMD Ryzen 7 8700G
The Ryzen 7 8700G is an AM5, 65 W, 8-core Zen 4 APU with Radeon 780M (12 CU, 2900 MHz). AMD’s sheet lists HDMI 2.1, DisplayPort 2.1, four displays, USB-C DisplayPort Alt Mode, two native USB4 40 Gbps ports, and PCIe 4.0 with 16 usable lanes — not PCIe 5.0. JEDEC memory is DDR5-5200 on two sticks and DDR5-3600 on four. Boxed 100-100001236. That is an iGPU shopping list. It is not a 120 W X3D / discrete-GPU ATX list, and it is not a reason to reopen the old X670E Hero / Strix / Carbon catalog on this URL.
The 2026 default is an ATX board that actually prints HDMI and DisplayPort on the rear I/O and names 8000-series in the PCIe footnote. ASUS’s TUF Gaming B850-PLUS WIFI spec does both: HDMI 2.1 4K60 + DisplayPort 1.4, and a PCIe 4.0 x16 slot that runs x8/x4 on Ryzen 8000. That is the pairing. A 14+2+1 80 A VRM and a Gen5 x16 slot do not make 780M faster.

Street prices move. If the TUF B850-PLUS is priced like an X870, buy the TUF B650-PLUS. Do not “save” by dropping to a board with no HDMI and no DisplayPort, and do not spend the SSD budget on an X670E Hero because the 2023 version of this page led with one.
How We Picked These Boards
- AMD’s 8700G sheet: AM5, 8 cores / 16 threads, 4.2 / 5.1 GHz, 8 MB L2 + 16 MB L3, 65 W TDP (cTDP 45–65 W), 95 °C Tjmax, unlocked, EXPO, Precision Boost Overdrive, Radeon 780M 12 CU at 2900 MHz, HDMI 2.1, DisplayPort 2.1, USB-C DP Alt Mode, four displays, two native USB4 40 Gbps ports, PCIe 4.0 with 20 total / 16 usable lanes, DDR5 dual-channel, JEDEC DDR5-5200 on 2×1R / 2×2R and DDR5-3600 on four DIMMs, max 256 GB, supporting chipsets A620, B650/E, X670/E, B840, B850, X870/E. Boxed 100-100001236. Source: AMD Ryzen 7 8700G product page. The CPU does not need an 18+2 110 A VRM. It needs rear video I/O and a vendor footnote that names 8000-series.
- The PCIe footnote every 8000G shopper misses: This chip is PCIe 4.0, 16 usable lanes. ASUS TUF B850-PLUS WIFI and TUF B650-PLUS WIFI both print a PCIe 4.0 x16 slot in x8/x4 mode for Ryzen 8000, and both drop M.2_1 to PCIe 4.0 x4 on that series (ASUS B850 spec, ASUS B650 spec). MSI B650 GAMING PLUS WIFI prints x8/x4 for 8700/8600/8400 (MSI spec). MSI’s Tomahawk Max WiFi II prints PCIe 4.0 x8 for the same APUs (MSI spec). Buying X870E for a Gen5 x16 GPU slot is wrong SKU for this product.
- Memory and USB4 are on the CPU, not on the sticker: Official JEDEC is two sticks at 5200. EXPO is a CPU feature — see the 8700G RAM page for kits. The iGPU shares those two channels, so one stick is the wrong buy. Native USB4 ×2 is also on the CPU. The TUF B850 rear Type-C is 20 Gbps plus a Thunderbolt / USB4 header; the TUF B650 is the same idea. If the desk needs the two 40 Gbps ports AMD printed, that is the X870 card (TUF X870-PLUS WIFI spec), not a reason to reopen Crosshair.
Best Motherboard for AMD Ryzen 7 8700G: Detailed Reviews
ASUS TUF Gaming B850-PLUS WIFI View on Amazon
| Chipset / size | AMD B850 · ATX |
|---|---|
| Video (iGPU) | HDMI 2.1 4K60 + DisplayPort 1.4 8K30 — ASUS spec, iGPU required |
| 8000-series PEG / M.2 | PCIe 4.0 x16 slot in x8/x4 mode · M.2_1 PCIe 4.0 x4 (not 5.0) |
| VRM | 14+2+1 × 80 A DrMOS — capacity for a 65 W APU |
| Memory | 4× DDR5, 256 GB, EXPO, dual-channel |
| Storage / net | 3× M.2 · 4× SATA · Realtek 2.5 GbE · Wi-Fi 7 (160 MHz / up to 2.9 Gbps) · BT 5.4 |
| USB4 | Rear USB-C is 20 Gbps · Thunderbolt / USB4 header, add-in card sold separately |
| Extras | BIOS FlashBack on the rear I/O · Q-Release · 8000 series on the CPU line |
Why it fits the 8700G. On the 9850X3D page this TUF is the value B850 because of the 80 A VRM. On this APU the pairing is the rear panel. ASUS prints HDMI 2.1 and DisplayPort 1.4, and it prints the 8000-series cut: the x16 slot becomes x8/x4, and the “Gen5” M.2_1 becomes PCIe 4.0 x4. That matches AMD’s PCIe 4.0 / 16-usable-lane sheet. Wi-Fi 7, 2.5 GbE, and FlashBack (24-pin, no CPU) are why this is the 2026 new-buy default instead of hunting a random 2023 B650 with no video outs. The 14+2+1 stage count is more VRM than a 65 W Phoenix chip spends. Do not buy this board to “unlock PCIe 5.0.” The CPU does not have it.
Skip this if the B850-PLUS is priced like an X870. Then the TUF B650-PLUS is the same HDMI + DP and the same 8000G footnote. Skip Amazon titles that say B850M, TUF B850-PLUS without WiFi, or TUF B650-PLUS — that last one is the Value card, not a substitute SKU mix-up you want in the cart by accident. If the case is mATX, this ATX board does not fit.
- HDMI and DisplayPort on the official spec — the 780M product
- ASUS writes x8/x4 and M.2_1 at PCIe 4.0 x4 for 8000-series
- FlashBack, Wi-Fi 7, current B850 stock
- You are paying B850 money for a Gen5 M.2 this APU cannot use
- No native USB4 — rear Type-C is 20 Gbps

| USB4 | Thunderbolt / USB4 header · rear Type-C is 20 Gbps, not 40 Gbps USB4 |
| Extras | BIOS FlashBack · 8000 series on the CPU line |
Why it fits the 8700G. The 9850X3D page told people to skip this TUF unless a BIOS named that January 2026 SKU. The 8700G launched in Q1 2024 and is on ASUS’s 8000-series line. The video block is the same idea as the B850 TUF: HDMI 2.1 + DisplayPort 1.4. The expansion block is the same idea: x8/x4 on 8000, M.2_1 at PCIe 4.0 x4. You are not giving up a Gen5 GPU slot this CPU never had. You are giving up Wi-Fi 7 and a newer chipset sticker. For a 780M desktop that is the value trade. ASUS’s own page lists 12(60A)+2(60A)+2 power stages — still more than a 65 W APU asks for.
Skip this if you want Wi-Fi 7 on day one and the B850 TUF is within ~$20. Skip the non-WiFi B650-PLUS and the B650M. Skip it as a 9850X3D board — that is a different CPU page.
- Official HDMI + DP and the same 8000G x8/x4 note as the Overall
- FlashBack, EXPO, three M.2, 2.5 GbE
- Stops the B850 Gen5 tax the 8700G cannot spend
- Wi-Fi 6, not 6E or 7
- Still no native USB4

Why it fits the 8700G. The old draft on this URL already had this MSI in the cheap pile, then buried it under X670E Hero. The reason to keep it is the spec sheet, not the 2023 price tier. MSI lists HDMI 2.1 and DP 1.4 for processors with iGPU, lists 8000-series, and writes x8/x4 on the 8700/8600/8400 row. Two CPU-side PCIe 4.0 M.2 slots is the honest 8700G storage layout — this chip does not feed a Gen5 x4 SSD. Wi-Fi 6E is nicer than the TUF B650’s Wi-Fi 6. You give up the third M.2 and the TUF FlashBack / Q-Release kit.
Skip this if the cart auto-filled B850 GAMING PLUS WIFI. MSI’s B850 GAMING PLUS WIFI specification page lists DisplayPort 1.2 on the graphics block and DisplayPort on the back-panel list — not HDMI. That is the wrong Gaming Plus for a TV-only desk. Also skip this MSI if you need three NVMe slots; that is either TUF.
- MSI writes HDMI + DP and the 8700 x8/x4 row in one table
- Wi-Fi 6E, Flash BIOS, two honest PCIe 4.0 M.2 slots
- Usually the cheapest name on this page that still has both video plugs
- Only two M.2
- Easy to buy the B850 Gaming Plus by title autocomplete
If You Need Something Else
These two are not cheaper versions of the Top 3. One exposes the USB4 ports AMD already put on the 8700G. The other is the 9850X3D — keep it if it is already in the case.
ASUS TUF Gaming X870-PLUS WIFI View on Amazon
| Chipset / size | X870 ATX |
|---|---|
| Why X870 | Two rear USB4 40 Gbps Type-C ports with DisplayPort Alt Mode, plus HDMI 2.1 — ASUS spec |
| 8000-series PEG | Still a PCIe 4.0 x16 slot in x8/x4 mode |
| Not why | 780M fps, or a 65 W TDP |
AMD’s 8700G sheet lists two native USB4 40 Gbps ports. Most B650/B850 boards never wire them; they ship a 10 or 20 Gbps Type-C and a header. X870/X870E is where AMD made USB4 mandatory. ASUS’s TUF X870-PLUS WIFI puts two USB4 Type-C ports on the rear, marks them as display outputs (DP 1.4a 4K60), and still lists HDMI 2.1 and Ryzen 8000 x8/x4. If the desk is a USB4 dock / 40 Gbps enclosure, this is the TUF-shaped way to use the ports the CPU already has. It does not turn the x16 slot back into x16, and it does not add PCIe 5.0 to Phoenix.
Skip this if nothing on the desk is USB4. That is the TUF B850-PLUS.
MSI MAG B850 Tomahawk Max WiFi II View on Amazon
| Chipset / size | B850 ATX |
|---|---|
| Video (iGPU) | HDMI 2.1 8K60 only — MSI spec, no DisplayPort |
| 8000-series PEG / M.2 | PCIe 4.0 x8 · M.2_1 and M.2_2 drop to PCIe 4.0 x4 on 8000 |
| Why it is Layer 2 | 14+2+1 × 80 A, 5 GbE, four M.2 — the 9850X3D Overall, not an APU buy |
If this board is already on the bench from an X3D plan, it will run an 8700G: MSI lists 8000-series, HDMI 2.1 FRL, and PCIe 4.0 x8 for 8700/8600/8400. Buy it new only if the monitor is HDMI and you wanted the Tomahawk extras anyway. A DisplayPort-only screen needs a dongle, or it needs one of the TUF boards. The 80 A VRM is not the 8700G product.
Skip this if you are shopping for the APU from scratch. That is the TUF B850-PLUS. Skip Amazon titles that drop the II unless you already know you want the original Max.
Frequently Asked Questions
Does the 8700G need an X870E motherboard?
No. AMD’s sheet lists B850 and B650 (and X670, X870, even A620) as supporting chipsets. The CPU is 65 W with 16 MB of L3, not a 120 W 96 MB X3D. X870/X870E is USB4, extra chipset lanes, and a higher sticker. It does not add PCIe 5.0 to this die, and the TUF X870-PLUS still runs the x16 slot at x8/x4 on Ryzen 8000.
Is the 8700G a PCIe 5.0 CPU?
No. AMD lists PCIe 4.0 and 20 / 16 usable lanes. Vendor manuals that advertise “PCIe 5.0 x16 from CPU” are describing 9000/7000. On 8700/8600/8400 the same slot is PCIe 4.0 x8 (MSI) or x8/x4 (ASUS). A discrete GPU still works. It does not get a Gen5 x16 link on this APU.
B850 versus B650 for the 8700G?
B850 is the 2026 mainstream sticker: newer BIOS stream, often Wi-Fi 7, and a Gen5 M.2 that this CPU cannot feed. B650 still has PBO and EXPO on the boards on this page, and on the two TUF sheets the 8000-series PEG and M.2_1 cuts are the same idea. New-buy default is the TUF B850-PLUS because it is the current ATX TUF with HDMI + DP. Value is the TUF B650-PLUS when B850 is a $50 premium for Wi-Fi 7. B840 is the A620-class part: memory EXPO only on many SKUs, no CPU overclock / PBO.
Two DIMMs or four?
Two. AMD’s JEDEC table for this CPU is DDR5-5200 on 2×1R or 2×2R; four sticks drop to DDR5-3600. The 780M shares those two channels — one stick is half the iGPU’s memory bus. Put the kit in the A2/B2 slots the vendor marks for 2-DIMM. Details and kits live on the best RAM for Ryzen 7 8700G page.
Where are the 8700G USB4 ports?
On the CPU. AMD lists two native USB4 40 Gbps ports and USB-C DisplayPort Alt Mode. The TUF B850-PLUS and TUF B650-PLUS rear Type-C ports are 20 Gbps; USB4 on those boards is a header plus a sold-separately add-in card. If the desk needs the two 40 Gbps ports, that is the TUF X870-PLUS on this page, not a Crosshair.
Final Verdict
For most Ryzen 7 8700G builds, buy the TUF Gaming B850-PLUS WIFI, two DDR5 sticks, and use the HDMI / DisplayPort on the board — not an X670E Hero and not a 9850X3D Tomahawk. The 780M is the product. If B850 is the expensive listing, the TUF B650-PLUS is the same APU footnote. Tight budget: B650 GAMING PLUS WIFI, and read the title so you do not get the B850 Gaming Plus. USB4 is the TUF X870-PLUS. Do not default to Strix, Carbon, or a board with no video outputs.
