Thanks to the new RDNA 2 architecture, AMD Radeon RX 6800 XT is a killer graphics card, with serious raytracing chops!
Find out why we gave the Radeon RX 6800 XT our Editor’s Choice Award!
AMD Radeon RX 6800 XT : Powered By RDNA 2!
- AMD Infinity Cache – a large 128 MB data cache that dramatically increases memory bandwidth, while reducing memory latency and power consumption.
- AMD Smart Access Memory – offers the Ryzen 5000 series processor greater access to its GDDR6 graphics memory for better gaming performance.
- DirectX 12 Ultimate – offering support for the next-generation games with DirectX Raytracing and Variable Rate Shading.
- New Ray Accelerator – delivers real-time lighting, shadow and reflection realism through DirectX Raytracing.
- Variable Rate Sharing (VRS) – dynamically reduces shading rate for better performance at little to no loss in image quality.
- DirectStorage Support – delivers faster load times and high-quality textures in the future.

Unboxing The AMD Radeon RX 6800 XT!
The AMD Radeon RX 6800 XT comes in a large and heavy cardboard box. Very heavy duty, with thick foam packaging.
AMD Radeon RX 6800 XT : Hands-On Experience!
Let’s take a closer look at the AMD Radeon RX 6800 XT in our hands-on video, and pictures.
Be careful when you handle it, because it is a rather bulky and heavy card.
That’s partly because it comes with a large (and heavy) 2.5-slot cooler with triple axial fans.
Part of the reason why it’s so heavy – it has a full-length die-cast aluminium backplate at the back.
Here you can see its thick heatsink, and how its cooler is designed to suck in air from the front of the card, and exhaust the hot air from the top and the bottom of the card.
It has four display connectors. From left to right : one USB Type C port, two DisplayPort 1.4 ports, and one HDMI 2.1 port.
The card uses up to 300 watts of power, and comes with two 8-pin PCI Express power connectors.
It should work with two 6-pin power cables though – both 8-pin and 6-pin cables deliver 150 watts.
AMD Radeon RX 6800 XT supports PCI Express 4.0, which offers double the bandwidth of PCI Express 3.0.
However, that requires you to use a PCI Express 4.0 motherboard, like the recommended AMD X570 motherboards.
But do not fret if you are on the Intel platform. It is backward-compatible with PCI Express 3.0, and will work just fine with PCIe 3.0 motherboards.
