AMD Radeon RX 6900 XT Liquid Cooled maximizes the performance of Navi 21
Last month, AMD launched the Radeon RX 6900 XT Liquid Cooled (LC) public graphics card. Compared with the previous air-cooled version of Radeon RX 6900 XT, Radeon RX 6900 XT Liquid Cooled uses a 120mm all-in-one water-cooled radiator, but it still only has two 8Pin external power ports. The game frequency has been increased to 2250 MHz, and the Boost frequency has been increased to 2435 MHz. At the same time, it has faster video memory.
Since AMD does not intend to supply directly to the retail market, Radeon RX 6900 XT Liquid Cooled does not have an official suggested retail price or information on the supply of board card manufacturers in the retail market. Recently PCGamesHardware got a Radeon RX 6900 XT Liquid Cooled and tested it. It was found that its TGP was increased to 350W (adjustable up to 400W), and the video memory rate reached 18.5 Gbps, which was higher than the previously mentioned 18 Gbps, which increased the maximum bandwidth to 591 GB/s.
There is no doubt that this is AMD’s most powerful desktop graphics card. In most cases, Radeon RX 6900 XT Liquid Cooled is better than NVIDIA GeForce RTX 3080/RTX 3080 Ti. Of course, this also depends on whether the light tracking function is turned on. At this point, even if the frequency of Radeon RX 6900 XT Liquid Cooled is increased, there is no way to make up for the gap.
In terms of noise, Radeon RX 6900 XT Liquid Cooled noise is less than that of ordinary graphics cards that use air-cooled heat dissipation during the game. But the sound will be louder when idle because most graphics cards that use air-cooled heat dissipation have intelligent speed control technology. At this time, the cooling fan usually stops, but the water pump of the Radeon RX 6900 XT Liquid Cooled is still running. In addition, the power consumption of the Radeon RX 6900 XT Liquid Cooled is higher than that of graphics cards that use air-cooled cooling regardless of whether it is idle or at full speed. After all, water-cooled cooling consumes more power.
