The Radeon RX 6800 is a high-end graphics card by AMD, launched in October 2020. Built on the 7 nm process, and based on the Navi 21 graphics processor, in its Navi 21 XL variant, the card supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 6800. 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 to reach the product's target shader count. It features 3840 shading units, 240 texture mapping units, and 96 ROPs. The card also has 60 raytracing acceleration cores. AMD has paired 16 GB GDDR6 memory with the Radeon RX 6800, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1700 MHz, which can be boosted up to 2105 MHz, memory is running at 2000 MHz (16 Gbps effective).
Being a dual-slot card, the AMD Radeon RX 6800 draws power from 2x 8-pin power connectors, with power draw rated at 250 W maximum. Display outputs include: 1x HDMI, 2x DisplayPort, 1x USB Type-C. Radeon RX 6800 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 40 mm, and it features a dual-slot cooling solution. Its price at launch was 579 US Dollars.
