The base of the new SAPPHIRE PULSE graphics card is a powerful Radeon RX Vega 56 chip featuring 3584 Stream Processors running with a factory-overclocked 1512 MHz Boost Clock. 8 GB of 2nd generation High Bandwidth Memory is clocked at 800 MHz (1600 Mbps Effective). Using a switch on the top of the card the user can choose a second UEFI BIOS with an efficiency preset, resulting in slightly lower clocks but also lower temperatures and power draw resulting in a quieter cooling.
To effectively cool a factory-overclocked GPU, SAPPHIRE is using a large heatsink with a copper base and a set of four 8 mm heatpipes. The card’s heatsink actually extends past the short PCB for an increased heat dissipation area. A robust cooling module is also applied to the VRM section, with separate heatsink units connected by a single 6 mm heatpipe and aluminum base. There is also a high thermal conductivity pad on the backplate. Two efficient dual-ball bearing fans spin at a nominal speed of up to 1650 RPM, maintaining a great airflow and quiet operation. Intelligent Fan Control III system ensures the fans start precisely at 55 degrees Celsius, providing a passive, noiseless cooling in idle.
The SAPPHIRE PULSE Radeon RX Vega 56 is a cohesively designed product, with the fan shroud, the aluminum backplate and the back heatsink frame all accentuating the series’ unique style.
Making no compromises on components, the SAPPHIRE PULSE Radeon RX Vega 56 features latest generation of Black Diamond Chokes for reduced coil temperatures and better power efficiency. The external PCI-E power connectors have a fuse protection built into the circuit to better protect the card.
