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.

The AMD Radeon RX 6800 XT is kept cool by a really thick heatsink, covered by a shroud 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.

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 PCI Express power

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.
