The graphics card comes equipped with 32 Compute Units and boasts 16 GB of GDDR6 memory, running at 18 Gbps. This model aims for a boost frequency close to 2.8 GHz. It requires a pair of 8-pin power connectors to meet its energy needs adequately. The cooler has four 6mm heat pipes in the following lengths: 299mm, 290.6mm, 452.3mm, and 323.9mm. The entire heatsink assembly, including copper cold plate, heatsink fins.

The design is massive, reaching almost 30cm and two and a half slots thick. The spinners keep the product cooled down whilst not being too noisy. Thermal behavior is primarily determined by key thermal limits, with fan performance closely linked to the GPU junction temperature, a target fan RPM of 1600 RPM, and memory temperature. When the card is under load, the fan typically maintains a steady RPM of 1600 until the card's temperature reaches either the Junction or Memory target. At that point, the fan will progressively increase its speed in an attempt to keep the temperature at the target level. If the card remains significantly cooler than the target temperature, the fan RPMs will drop below 1600. The fan will stop completely when the card falls below all fan stop temperature thresholds and restart when the card reaches any of the fan start temperature thresholds.

In terms of aesthetics, the card's design is subtle, with white,red and dark hues, and it foregoes active LED lighting. Manually adjusting the fan settings through the AMD Adrenalin Software will override the BIOS settings. To revert to the factory BIOS fan profile after using a manual profile, you may need to perform a complete driver wipe and use Display Driver Uninstaller (DDU) tool.

The card retains compatibility with standard 8-pin power connectors and has a power provision capacity of up to 375W, considering the contribution from the PCIe x16 slot. AMD lists the Total Board Power at up-to 190W, which is marginally higher than the 8GB models. Power consumption in real-world gaming appears to align with these specifications, varying with the game's demands.
