The Radeon RX 6800 XT is a high-end graphics card by AMD, launched on October 28th, 2020. Built on the 7 nm process, and based on the Navi 21 graphics processor, in its Navi 21 XT variant, the card supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 6800 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 520 mm² and 26,800 million transistors. Unlike the fully unlocked Radeon RX 6900 XT, which uses the same GPU but has all 5120 shaders enabled, AMD has disabled some shading units on the Radeon RX 6800 XT to reach the product's target shader count. It features 4608 shading units, 288 texture mapping units, and 128 ROPs. The card also has 72 raytracing acceleration cores. AMD has paired 16 GB GDDR6 memory with the Radeon RX 6800 XT, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1825 MHz, which can be boosted up to 2250 MHz, memory is running at 2000 MHz (16 Gbps effective).
Being a dual-slot card, the AMD Radeon RX 6800 XT draws power from 2x 8-pin power connectors, with power draw rated at 300 W maximum. Display outputs include: 1x HDMI 2.1, 2x DisplayPort 1.4a, 1x USB Type-C. Radeon RX 6800 XT is connected to the rest of the system using a PCI-Express 4.0 x16 interface. The card's dimensions are 267 mm x 120 mm x 50 mm, and it features a dual-slot cooling solution. Its price at launch was 649 US Dollars.
