AM4 vs LGA 1151: Key Specs
cpu socket
The MSI MPG X570 uses the AM4 socket, which supports 2nd and 3rd Gen AMD Ryzen processors. This platform offers a clear path for modern CPU upgrades. The Biostar board uses the LGA 1151 socket, designed for Intel Core i3, i5, and i7 chips. This older socket limits you to earlier generation Intel CPUs. If you want future-proofing for AMD processors, the AM4 option is the stronger choice. The LGA 1151 board is locked to Intel’s previous generation architecture.
chipset
Chipsets define the features and expansion capabilities of a motherboard. The MSI board features the AMD X570 chipset, a high-end option that supports advanced connectivity and PCIe 4.0 speeds. The Biostar motherboard uses the Intel B250 chipset. This is a mid-range option that lacks the latest expansion standards. The X570 chipset generally provides better bandwidth and more modern features than the B250. You get more flexibility with the AMD platform’s newer chipset technology.
pcie version
PCIe version impacts how fast your graphics card and storage drives communicate with the CPU. The MSI MPG X570 supports PCIe 4.0, which doubles the bandwidth compared to previous generations. This is ideal for fast NVMe SSDs and next-gen GPUs. The Biostar LGA 1151 board does not list PCIe version support, but the B250 chipset typically only supports PCIe 3.0. The AM4 board offers superior data transfer speeds for compatible components. This makes a significant difference for high-performance storage and graphics.
wi-fi
Built-in wireless connectivity saves you from buying separate adapters. The MSI motherboard includes on-board Wi-Fi 5 (802.11ac) with MU-MIMO support. This allows for stable wireless connections and better performance when multiple devices are active. The Biostar LGA 1151 motherboard does not list any Wi-Fi capabilities in its specifications. You would need to purchase a separate PCIe or USB Wi-Fi adapter for this board. The MSI option provides a more complete out-of-the-box experience for wireless networking.
form factor
Both motherboards use the standard ATX form factor. This means they fit in most mid-tower and full-tower cases. The dimensions are slightly different, with the Biostar board being larger in length and width. The MSI board is slightly more compact. Since both are ATX, case compatibility is not a deciding factor for you. You can install either board in a standard ATX chassis without issues. The physical size difference is minor and unlikely to affect your build constraints.
Which motherboard fits your build
Users needing modern AMD Ryzen support
The MSI MPG X570 uses the AM4 socket, supporting 2nd and 3rd Gen AMD Ryzen processors. This ensures compatibility with current high-performance CPUs. It also features PCIe 4.0 for faster data transfer speeds compared to older standards. On-board Wi-Fi 5 adds convenience for wireless connectivity without extra cards.
Those building with Intel Core i-series
The Biostar board uses the LGA 1151 socket, designed for Intel Core i7, i5, and i3 processors. This makes it the only choice if you are using Intel hardware. It supports DDR4 memory and fits standard ATX cases. The B250 chipset provides stable performance for general computing tasks.
Builds requiring built-in wireless networking
Only the MSI MPG X570 includes on-board Wi-Fi 5 with MU-MIMO support. This allows you to connect to wireless networks without installing a separate expansion card. The board also features Audio Boost 4 for improved sound quality. These integrated features simplify the build process and save expansion slots.
