Performance Rating

The Radeon RX 6900 XTX was a graphics card by AMD, that was never released. Built on the 7 nm process, and based on the Navi 21 graphics processor, in its Navi 21 XTXH variant, the card supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 6900 XTX. 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. It features 5120 shading units, 320 texture mapping units, and 128 ROPs. The card also has 80 raytracing acceleration cores. AMD has paired 16 GB GDDR6 memory with the Radeon RX 6900 XTX, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 2075 MHz, which can be boosted up to 2435 MHz, memory is running at 2250 MHz (18 Gbps effective).
