X670 vs B650: Which AMD AM5 Chipset Is Right for You?

of AMD AM5 platform It's here, and with it comes two new chipsets: the X670 and the B650. Both chipsets offer a number of features and advantages, but also have their own strengths and weaknesses. So when comparing the X670 vs the B650, which one is right for you?

X670 chipset

The X670 chipset is the more powerful of the two, designed for high-end users who want the best possible performance. The X670 offers several features that the B650 chipset does not have, including:

  • Support for PCIe 5.0: X670 Supports PCIe 5.0.which is the latest and fastest version of the PCIe standard. This means you can get the most out of your PCIe 5.0 devices, such as high-end graphics cards and NVMe SSDs, as more of them become available, ie.
  • More PCIe lanes: The X670 chipset has 36 PCIe lanes versus the 44 available from the B650. This means better throughput for connecting devices to your motherboard, such as multiple graphics cards, storage devices, and expansion cards.
  • Overall connectivity: The X670 offers the widest range of connectivity options within the AM5 including 8 SATA and 12 USB 10 Gbps ports.
  • Better VRMs: The X670 has better VRMs than the B650. VRMs are responsible for powering your CPU, so better VRMs can help you overclock your CPU more easily as well as manage the thermals of higher-end Ryzen processors, even when Do not overclock.

Best for: Builds with ambitious Ryzen 7 or 9, overclocking, workstations.

B650 chipset

The B650 chipset is the more affordable option, making it a good choice for budget-minded users who don't need the features of the X670 chipset mentioned above. These boards still fully support AM5 socketed processors like the Ryzen 7000, but lack some of the extras offered by the X670. A few notes to be aware of:

  • Support for PCIe 4.0 only: The B650 chipset only supports PCIe 4.0, the previous generation of the PCIe standard. Gen 5 is only an option with the B650E (more on that later).
  • Connectivity: The B650 offers no more than 4 SATA and 6 USB 10Gbps ports, limiting expansion and peripheral options.
  • Cooling/Power Management: Although the chipset officially supports the highest end of the product stack like the 7950X, lower-end VRMs are best used with more mid-range CPU options.

Best for: Build with a budget Ryzen 3 or 5.

How about the X670E and B650E?

In addition to the standard X670 and B650, AMD has also released “Extreme” versions of each, abbreviated as “E”. These E versions offer the same features but with different PCIe Gen 4 and Gen 5 allocations. The X670E has 20 lanes dedicated to Gen 5 vs. 4 with the X670. The B650E has 20 Gen 5 lanes vs. 0 in the B650.
