As the price of DDR5 memory continues to climb, the AM4 platform has once again captured the market's attention, thanks to its compatibility with DDR4 memory. In light of this trend, Gigabyte has recently introduced four new DDR4 AM4 motherboards. These include two models featuring A520 chipsets and two with B550 chipsets, available in both Micro-ATX and Mini-ITX form factors. Among these offerings, the A520M H ARGB stands out as an entry-level option, equipped with a PCIe 3.0 x16 slot and HDMI output. Meanwhile, the B550I AORUS Pro AX 1.4 represents a high-end Mini-ITX motherboard that supports PCIe 4.0, boasting dual NVMe slots and Wi-Fi 6E connectivity. The B550M H ARGB, similar to the A520M H ARGB but with an upgrade to the B550 chipset, also supports PCIe 4.0. Lastly, the A520I AC 1.5 is an entry-level Mini-ITX motherboard that supports PCIe 3.0 and comes with a newly integrated Wi-Fi card.
