FRIENDLY PCB DESIGNįully automated production process ensures top quality of the circuit boards and eliminates sharp protrusions of the solder connectors seen on the conventional PCB surface.

The metal back plate not only provides an aesthetical shape, but also enhances the structure of the graphics card to provide complete protection. The heat pipe also covers the VRAM through a large metal plate contact to ensure proper cooling. The shape of the pure copper heat pipe maximizes the direct contact area with the GPU. SCREEN COOLINGĮxtended heatsink design allows air flow to pass through, providing better heat dissipation. Graphene nano lubricant can extend the life of fan by 2.1 times, close to the life of double ball bearing, and is quieter.

The airflow is spilt by the triangular fan edge, and guided smoothly through the 3D stripe curve on the fan surface. The 3D Active Fan provides semi-passive cooling, and the fans will remain off when the GPU is in a low load or low power game.

GIGABYTE turns the adjacent fans in the opposite direction, so that the airflow direction between the two fans is the same, reducing the turbulence and enhancing the airflow pressure. There’s another support post on this topic which is more informing, as Andy from Affinity explained that they weren’t currently able to get Nvidia cards to work reliably, as the hardware and drivers are flakey.The WINDFORCE 3X cooling system features three 80mm unique blade fans, alternate spinning, 5 composite copper heat pipes direct touch GPU, 3D active fan and Screen cooling, which together provide high efficiency heat dissipation. There are older AMD cards which support metal that aren’t on that list either, such as the SAPPHIRE Radeon HD 7950 Mac Edition.

The AMD cards belonging to “family 2” are much more recent. That doesn’t surprise me that Nvidia cards aren’t part of “family 2” as Apple stopped dealing with Nvidia around 2012/2013. I don't know what specifically the Affinity apps need to provide metal compute acceleration, but clearly Apple has not been spending the time to make nVidia cards work with the full feature set of Metal. It looks like Metal support is divided into two basic GPU 'families' by Apple right now: 'family 1' offers less functionality than 'family 2'.įrom what little documentation I have been able to scrounge up, there are NO nVidia cards in 'family 2':
