About ASRock Radeon RX 7900 GRE Challenger OC 16 GB GDDR6
The ASRock Radeon RX7900GRE Challenger OC 16GB, based on AMD’s RDNA3Navi31 architecture, is now available. This card offers strong rasterization performance thanks to its 80 compute units (5,120 stream processors), 64 MB Infinity Cache, and 16 GB of 18 Gbps GDDR6 memory on a 256-bit interface.
Factory OC gives it a performance advantage by increasing clock speeds from a game clock of about 1927 MHz to about 2333 MHz. On top of a nickel-plated heatsink with heatpipes and a robust metal backplate, it has two striped axial fans that spin down below about 60°C for silent idle. Broad display support is ensured by dual 8-pin power inputs, PCIe 4.0 x 16, and outputs that include 3× DisplayPort 2.1 and 1× HDMI 2.1. The card needs a 750W power supply and is about 269 x 130 x 51 mm in size.
