In this chipset, they are also producing a Mini-ITX motherboard in the near future.
ASRock Phantom Gaming motherboards are synonymous with great power control to the CPU, allowing for the system to run efficiently but also at low temperatures for even the most intense games. Also, with their Intel utilization, they promise "best throughput performance, lower CPU utilization, enhanced stability," for a better experience for users. The Phantom Gaming series also will utilize Thunderbolt 4 connectivity, and some of the boards will have dedicated wireless options for their boards.
The Extreme and Steel Legend motherboards offer high performance but are more featured on the look of the board, showcasing aesthetics as well as efficiency and strength. Features like dedicated connections for GPUs are shown on each model. The Extreme and Steel Legend boards also allow for superb memory capacity ability for consumers.

The NZXT appears to only focus on the Intel Z690, which will offer a higher-end experience for users.
The list, shown in the picture below, does not feature any of the Taichi, Aqua, or OC Formula Series. but rest be assured, those motherboards will also make their way during launch in November 2021 but the focus is more on the Phantom Gaming and PRO lines, especially with the Z690 and B660 chipsets.
