AMD will not be releasing a reference card, pretty much the OEM 5500 you have been able to see, holds the reference design, but that is commercially not available in retail, they will end up in pre-built systems. That leaves the AIB (board partner) cards. All will be different in configuration with regard to display connectors, cooler and, sure, the allowed board power, as that defines how fast the clock frequency will go before throttling the GPU.
- Reference clocks: 1717 MHz (Game) / 1845 (Boost) / 14 Gbps Memory
- Actual clocks: 1737 MHz (Game) / 1845 (Boost) / 14 Gbps Memory
This card will have a board power of ~130 Watts and was fitted with one 8-pin power connector. Display connectors include:
- 1x HDMI
- 3x DisplayPort
- 0x DVI
The card offers HDMI 2.0b, DisplayPort 1.4, and yes, PCIe Gen 4.0 support. Gigabyte offers the Gaming OC card with a Windoforce revision cooler, three fans should be plenty to cool that ~125 Watt product.
