The Radeon RX 6900 XT will be a graphics card by AMD, that is expected to launch on October 28th, 2020. Built on the 7 nm process, and based on the Navi 21 graphics processor, in its Navi 21 XTX variant, the card supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 6900 XT. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. The Navi 21 graphics processor is a large chip with a die area of 536 mm² and 23,000 million transistors. It features 5120 shading units, 320 texture mapping units, and 64 ROPs. AMD has paired 16 GB GDDR6 memory with the Radeon RX 6900 XT, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1529 MHz, which can be boosted up to 2330 MHz, memory is running at 2000 MHz (16 Gbps effective).
Being a dual-slot card, the AMD Radeon RX 6900 XT draws power from 2x 8-pin power connectors, with power draw rated at 255 W maximum. Display outputs include: 1x HDMI, 2x DisplayPort, 1x USB Type-C. Radeon RX 6900 XT is connected to the rest of the system using a PCI-Express 4.0 x16 interface.
