Comparing X399 STR4 vs X670E Taichi
CPU socket
The CJWDPDSWEZ X399 STR4 Motherboard uses the STR4 socket. This socket is designed specifically for AMD Ryzen Threadripper processors. It supports high-core-count CPUs like the 2950X and 2970WX. These chips are built for extreme multi-threaded workloads. The CJWDPDSWEZ X670E AM5 E-ATX uses the AM5 socket. This socket supports modern Ryzen 7000 and 9000 series desktop CPUs. It targets mainstream enthusiasts and gamers rather than workstation users. You must choose the socket that matches your intended processor. The STR4 is for legacy Threadripper builds. The AM5 is for current-generation desktop performance.
Memory type
Memory standards differ significantly between these two options. The X399 STR4 board supports DDR4 memory. DDR4 is a mature standard with widely available and affordable modules. It offers reliable performance for most tasks. The X670E Taichi board supports DDR5 memory. DDR5 provides higher bandwidth and improved power efficiency. It is the current standard for new high-end builds. DDR5 modules are generally more expensive than DDR4. You need to ensure your budget covers the newer memory type if you choose the AM5 board. DDR4 is better for cost-sensitive upgrades. DDR5 is better for future-proofing and peak speed.
PCIe version
Expansion slot speeds vary by generation. The X399 STR4 motherboard operates on PCIe 3.0. This version provides sufficient bandwidth for most current graphics cards and storage devices. It is a stable and proven standard. The X670E Taichi motherboard supports PCIe 5.0. This is the latest generation with double the bandwidth of PCIe 4.0. It allows for faster data transfer rates for next-generation GPUs and NVMe drives. If you plan to use the newest high-speed components, the PCIe 5.0 support is a clear advantage. For older components, PCIe 3.0 remains fully functional. The newer version offers more headroom for future upgrades.
M.2 slots
Storage expansion capacity is another key difference. The X399 STR4 board includes three M.2 slots. This allows you to install three separate NVMe SSDs for storage or cache. It provides good flexibility for moderate storage needs. The X670E Taichi board includes four M.2 slots. This gives you one additional slot for storage expansion. You can install more drives without needing extra adapters or expansion cards. This is useful for users who need large local storage arrays. The extra slot provides more versatility for content creation or heavy data logging. If you need maximum storage connectivity, the four-slot board offers a slight edge.
Form factor
Physical size affects case compatibility. The X670E Taichi is listed as an E-ATX form factor. E-ATX boards are larger than standard ATX boards. They require a case with ample space and proper mounting points. The X399 STR4 board is listed as a size of One Size. The specific dimensions are not provided in the data. However, X399 boards are often large due to the CPU cooler clearance. You must check your case specifications carefully for both. The X670E is explicitly E-ATX. The X399 size is unspecified. You should measure your intended chassis before purchasing either board to ensure a proper fit.
Which motherboard fits your needs?
Existing Threadripper users upgrading
If you already own a Threadripper CPU, this board is your only option. It features the STR4 socket, which is required for those specific processors. You must use DDR4 memory with this platform. The PCIe 3.0 standard supports your current graphics cards. Choose this model to maintain compatibility with your existing high-core-count hardware without changing your entire system foundation.
Building a new modern PC
For new builds, this board offers significantly faster connectivity. It supports DDR5 memory, which provides higher bandwidth than DDR4. The PCIe 5.0 standard ensures future-proofing for next-generation graphics cards and storage drives. You get four M.2 slots for ample storage expansion. This platform is designed for modern AM5 processors, offering better performance per watt for contemporary gaming and productivity tasks.
Seeking maximum storage capacity
This motherboard includes four M.2 slots, giving you more options for installing NVMe SSDs. The older STR4 board only provides three slots. If you plan to store large libraries of games or video files directly on fast drives, the extra slot on the X670E board is valuable. The E-ATX form factor also provides more physical space for mounting multiple drives without crowding other components.
