The Gigabyte Z890 AORUS MASTER is the objective winner, securing victory in ten out of thirteen comparable specifications. Its most significant technical advantage is its maximum memory capacity, which is 167% higher than that of the alternative. While the ASRock B760M PG Lightning holds its own in two categories, it falls behind in the majority of technical metrics, trailing the superior memory support and feature set offered by the Gigabyte Z890 AORUS MASTER.

Users prioritizing high-capacity memory configurations should select the Gigabyte Z890 AORUS MASTER for its substantial advantage in that area. Conversely, the ASRock B760M PG Lightning is the logical choice for budget-conscious builders, as it offers an MSRP that is 80% better than its competitor. Choosing between these two motherboards depends entirely on whether your build requires maximum memory overhead or a more cost-effective entry point for your system.
