The boards retain DDR4 support while adding Wi-Fi 7, a 10-phase 60 A DrMOS VRM, expanded cooling, and convenience features for antennas, M.2 drives and graphics cards. Alongside the hardware, Gigabyte introduced X3D Turbo Mode 2.0, a BIOS-level performance boost for Ryzen X3D processors that automatically optimises CPU, memory and power delivery, delivering up to 34% higher frame rates in gaming and notable gains in multi-core benchmarks. Two days later, Gigabyte provided additional details, describing specific models including a Micro-ATX B550M X AORUS ELITE WIFI7 and plans for ATX variants. The boards feature Wi-Fi 7 with 160 MHz channels, 2.5 Gb Ethernet, Bluetooth 5.4, four DDR4 slots, PCIe 4.0 x16, and dual M.2 slots. The company positioned the series as a cost-effective alternative to DDR5 platforms, emphasizing the continued affordability of DDR4 memory while supporting Ryzen 3000, 4000 and 5000 series CPUs. By early August, Gigabyte further detailed the B550 lineup, which will include Gaming, Eagle, and Elite variants in both ATX and Micro-ATX formats. These models feature enhanced thermal management using larger heatsinks and 5 W/mK thermal pads, alongside tool-less M.2 installation. Simultaneously, Gigabyte expanded its high-end offerings to the AM5 platform with the introduction of the X870 AORUS Infinity motherboard, designed for Zen 5-based Ryzen 9000 CPUs and featuring USB 4.0 and PCIe Gen5 support. This X870 AORUS INFINITY model serves as a 40th-anniversary special edition, featuring an 18+2+2 phase digital power supply and a rotated layout designed to facilitate liquid nitrogen cooling for extreme overclocking. ## Timeline ### 2026-08-11: Gigabyte and ASRock announce new X870 motherboards for AMD AM5 Gigabyte and ASRock introduce new X870 motherboards for the AMD AM5 platform, featuring extreme overclocking capabilities and PCIe 5.0 support for professional creators. 2 sources. https://clstr.news/cluster/gigabyte-and-asrock-announce-new-x870-motherboards-for-amd-am5 ### 2026-08-07: Gigabyte announces new Aorus motherboards for AMD AM4 and AM5 platforms Gigabyte introduces new Aorus B550 X motherboards for AMD's AM4 socket and showcases the X870 AORUS Infinity for the newer AM5 platform featuring USB 4.0 and PCIe Gen5. 2 sources. https://clstr.news/cluster/gigabyte-announces-new-aorus-motherboards-for-amd-am4-and-am5-platforms ### 2026-08-02: Gigabyte launches B550 motherboards with Wi‑Fi 7 Gigabyte unveiled B550‑based motherboards for AM4, adding Wi‑Fi 7, 60 A power design and DDR4 support, aimed at budget builders and enterprises seeking legacy platform performance with modern wireless speeds. 5 sources. https://clstr.news/cluster/gigabyte-launches-b550-motherboards-with-wifi-7 ### 2026-07-31: GIGABYTE Launches B550 X Series Motherboards and X3D Turbo Mode 2.0 for AMD Ryzen Processors GIGABYTE unveiled B550 X Series motherboards for AMD Ryzen 5000 CPUs with Wi‑Fi 7 and enhanced cooling, and introduced X3D Turbo Mode 2.0 to boost Ryzen X3D performance by up to 34% in games. 7 sources. https://clstr.news/cluster/gigabyte-launches-b550-x-series-motherboards-and-x3d-turbo-mode-20-for-amd-ryzen-processors --- Cite as: Gigabyte B550 motherboard launch and AM5 expansion.
