Page 1: Big Navi with AiO cooling: ASUS ROG Strix LC Radeon RX 6800 XT OC Edition in the test

After the successful start of the Radeon-RX – 6800 – Series a few days ago, the first custom model follows today. In the form of the ASUS ROG Strix LC Radeon RX 6800 XT OC Edition, we’re looking at a real high- End branch, which comes with an all-in-one cooling ex works. Except for a custom water cooling, it shouldn’t get much better in terms of performance potential, but at a later point in time we will certainly look at other custom models.

At the start of the new Big Navi cards, ASUS presented a whole series of corresponding cards. There are the TUF models, which are supposed to serve the middle class more or less. The ROG Strix series is positioned above it, which goes a step further in terms of cooling and functions such as RGB lighting. The ROG Strix LC Radeon RX 6800 XT OC Edition, which we tested today, tops it all off. All-in-one cooling should ensure maximum performance at the lowest possible temperatures and volume.

But let’s first take a look at the technical data of the card.

Like any model of the Radeon RX 6800 XT also uses the ROG Strix LC Radeon RX 6800 XT OC Edition the Big Navi GPU with 26, 8 billion transistors based on the RDNA-2 architecture. All details can be found in the launch article for the Radeon RX 6800 and Radeon RX 6800 XT. From the point of view of the GPU there are no differences, but there are differences in the clock rate. While AMD has a typical game clock of 2.0 for its reference version 15 provides MHz, the ROG Strix LC Radeon RX 6800 XT OC Edition 2 . 110 MHz. In the Boost, AMD provides up to 2. 250 MHz, loud ASUS should be with the AiO cooled model 2. 360 MHz and more.

Otherwise ASUS also sees a memory expansion with 16 GB GDDR6 before, which has a 256 Bit wide memory interface is connected. In order to compensate for the comparatively narrow interface, AMD has given the Big Navi GPUs a 128 MB large Infinity Cache. You can also find more details on this in the detailed start article.

On the details of the ASUS ROG Strix LC Radeon RX 6800 XT OC Edition we will go into more detail in a moment. First of all, let’s take a look at the specifications for this test. ASUS offers a quiet and a performance BIOS. We tested it in the Quiet BIOS. ASUS also enables the power limit to be shifted by +/- 15%. But this is already the case with the reference models.

Between and 345 W you can set the power limit of the card. Of course we tested with the standard value of 300 W. When overclocking we will but still see how big the margin is.
