Choosing between the X870 and X670E is one of the most common decisions for AMD builders in 2026. Both chipsets use the AM5 socket and support DDR5 memory, but they differ in features, pricing, and target audience.
This guide breaks down exactly what separates these two chipsets so you can make the right choice for your build.
Quick Comparison
| Feature | X870 | X670E |
|---|---|---|
| Generation | Zen 5 native | Zen 4 native |
| Socket | AM5 | AM5 |
| PCIe Gen 5 GPU | Yes | Yes |
| PCIe Gen 5 M.2 | Yes (multiple) | Yes (1-2 slots) |
| USB4 | Standard | Some models |
| WiFi 7 | Standard on WiFi models | WiFi 6E |
| Overclocking | Full support | Full support |
| Price Range | £200–£400 | £180–£350 |
| CPU Compatibility | Ryzen 7000 + 9000 | Ryzen 7000 + 9000 (BIOS update) |
When to Choose X870
X870 is the better choice if you want the latest features, improved power delivery, and potentially better future-proofing. It’s designed for users who want the newest technology and are willing to pay a modest premium for it. Builders focused on longevity and maximum feature access should lean towards X870.
When to Choose X670E
X670E remains an excellent choice, especially if you’re on a tighter budget or don’t need the absolute latest features. The mature ecosystem means wider board selection, more reviews, and often better pricing. Many X670E boards offer nearly identical real-world performance for gaming and productivity workloads.
RAM and SSD Compatibility
Both X870 and X670E support DDR5 memory with similar speed capabilities. SSD compatibility is also largely the same, with both chipsets offering multiple M.2 NVMe slots. The key difference is that X870 boards may offer more PCIe Gen 5 M.2 slots on mid-range models compared to X670E.
Our Recommendation
For new builds in 2026, X870 is generally the better choice — the price premium is small and you get a newer platform with longer support. However, if you find a great deal on a X670E motherboard, it’s still a perfectly capable chipset that will serve you well for years to come.
Frequently Asked Questions
Is X870 worth the upgrade from X670E?
For new builds, yes — the price difference is typically small and you get a newer platform. For existing X670E owners, there’s rarely a compelling reason to switch unless you need a specific feature only available on X870.
Can I use the same RAM on both?
Yes, both chipsets use the AM5 socket and support DDR5 memory. RAM that works on one will work on the other, assuming it meets the specific board’s QVL specifications.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
