AMD X670E Vs B650E – What Are The Key Differences?

AMD recently launched their AM5 motherboards with the latest chipsets, X670E and B650E, with LGA sockets, DDR5 RAM and PCIe 5.0 connectivity, and many other high-end features.

The new E-marked chipsets have already sparked interest as AMD has launched its first “Extreme” chipsets till now.

It is clear that the AMD X670E and AMD B650E chipset motherboards will be advanced and will offer more than you imagine. Let’s check their features and specifications to know the differences and which one is better for you.

What is the AMD X670E Motherboard?

The AMD X670E motherboard is powered by the chipset X670E, one of the most powerful chipsets of the Ryzen 7000 series. The chipset is unique because it comprises two smaller chipsets communicating through four PCIe 4.0. The motherboard chipset is built with AMD EXPO technology and also offers PCIe 5.0 support for the NVMe and graphics. In short, it is ideal for high-end games that have advanced graphics.

What is AMD B650E Motherboard?

AMD B650E is also another modern motherboard from AMD equipped with the AMD B650E chipset. It is built with AMD EXPO technology and supports DDR5 memory. It is a single chipset motherboard, and the chipset offers optional PCIe 5.0 support for the NVMe drive.

What are the Key Differences Between the X670E and B650E Motherboards?

1. CPU Socket (AM5)

AMD started to phase out all of its motherboards to the AM5 CPU socket after introducing the Ryzen 7000 series. It is the new LGA society with 1718 pins. It is essential if the motherboards are paired with the DDR5 RAM and PCIe 5.0 lanes.

2. PCIe (CPU 5.0, 4.0 Lane; Chipset 4.0, 3.0)

PCIe or Peripheral Component Interconnect Express is essential for graphics performance as it connects the graphics card with the SSDs.

The X670E offers the best connection in the case of PCIe. It supports PCIe 5.0 compatible lanes- 1 for 16 lanes or two with eight lanes each for the graphics slot. It also has four PCIe 5.0 lanes.

Additionally, 12 PCIe 4.0 lanes and 8 PCIe 3.0 lanes can be used for the motherboard, Wi-Fi, or Ethernet connections.

On the other hand, the B650E only offers 16 PCIe 5.0 lanes for the graphics slot, 4 PCIe 5.0 lanes for NVMe solid-state drive, and 4 PCIe 5.0 lanes for other purposes. Besides these, it comes with 12 PCIe 4.0 and 3.0 lanes, which you can use according to the motherboard compatibility. 

3. CPU Generation (Ryzen 9, Ryzen 7)

AMD has recently started the new E series chipset. The”E” stands for “extreme,” denoting high power and advanced mechanics. Both these work fine with the AMD Ryzen 7000 processors. Both the chipsets can easily handle the latest Ryzen 9 processors.

4. DMI 4.0 Lanes

The Direct Media Interface 4.0 lane or DMI connects the Northbridge and Southbridge of the motherboard/. The Northbridge controls the memory sector like the CPU, PCIe, and RAM. On the contrary, the Southbridge controls the input-output controller hub like USB, BIOS, and SATA with the CPU. In short, the DMI 4.0 lane is needed to connect the chipset with the CPU.

Currently, the DMI 4.0 lane is the highest, and both chipsets support 4 DMI 4.0 paths.

5. Integrated Graphic Card

Regarding integrated graphics cards, both support the CPU units’ integrated graphics cards. The performance is also quite similar. But, since the X760E is made for the Ryzen 9 7000 series, it may perform better. But, that performance difference is not drastic.

6. CPU Overclocking & Memory Overclocking Support (MHz)

AMD designed these two motherboards, especially for the Ryzen 7000 CPUs. Hence, these two come with VRM power phases. Most AMD chipsets (except those from the “A” series) have overclocking support.

The X670 comes with an active OC tuner and is authorized for overclocking. That means you can overclock the CPU speed without any issues. On top of that, you can switch the CPU overclocking speed between the Precision Boot Overdrive 1(PBO 1) state, Default Precise Overclocking Function stage, and Manual overclocking stage. Hence, you can fine-tune the CPU overclocking mechanism to get the best performance through the motherboard.

The B650E, despite being less expensive, also supports overclocking. Let’s check two AMD motherboards from Asus. The ROG Crosshair X670E motherboard comes with 20+2 power stages, and the ROG STRIX B650E motherboard has power stages of 18+2. Hence, it is clear that both of these will support CPU and memory overclocking to give out the maximum performance.

But, if you check out the result, the X670E motherboard has better overclocking effects than the B650E model. In other words, the X670E motherboard offers high-end overclocking, and the B650E will offer a somewhat steady overclock for a mid-range CPU.

Just like CPU overclocking, both these motherboards also support memory overclocking. Both motherboards come with a one-click memory overclocking mechanism that can improve the performance of the 1080P settings. It can improve the latency of the DDR5 RAM. But, to get the memory overclocking, you need to pair the motherboard with DDR5 RAM.

Besides the automated memory overclocking, both motherboards will also support manual overclocking. You can customize the BIOS settings with the board to manually overclock the memory.

Even though there is not much difference, the X670E motherboard has a higher memory clock speed. Hence, it may give a better result.

7. RAID Support and Modes

RAID, or Redundant Array of Inexpensive Disks, is an important mechanism in modern motherboards as it prevents data theft and accidental data loss.

X670E and B650E both come with four RAID modes of These two chipsets also support AMD RAIDXpert2 technology. Both X670E and B6540E offer the PCIe RAID 0/1/10 and SATA 0/1/10. Hence, you get complete data loss protection.

8. Max No. of SATA 6.0 Gb/s (Number)

A higher number of SATA or Serial Advanced Technology Attachment means the motherboard can connect with more optical and hard drives through the serial cables and two pairs of conductors/.

The X670E has eight SATA ports, while the B650E has four native SATA ports. If you want to use more than two SATA-based drivers with the B650E chipset, you may need an add-in card to accommodate the extra drivers.

9. No. of USB Ports (3.2 {20Gbps/10Gbps/5Gbps},2.0 gen)
