Asus has introduced its highest-performing AMD Radeon RX 6900 XT-based graphics card to date, the ROG Strix LC RX 6900 XT Top Overclocked Edition. The board features an out-of-box boost clock of 2525 MHz and uses a hybrid air / liquid cooling system to lower temperatures and maximize overclocking potential.  

Asus were among the first vendors to introduce an AMD Radeon RX 6900 XT-powered graphics card with a hybrid cooling system, so the new 'Top Overclocked Edition' with the same cooler is almost certainly based on AMD's Navi 21 XTXH silicon that has 5,120 stream processors, no limitations when it comes to clock rates and which has set an absolute GPU frequency record of 3225 MHz.

Asus' hybrid cooling system is actually pretty regular: it uses a blower-type fan to cool-down VRM and a closed-loop liquid cooling system featuring a large cold plate (that covers both GPU and memory) as well as a 240-mm radiator with two fans. Since the graphics card is designed for enthusiasts who sometimes use large EATX cases, the LCS uses 600 mm tubing to enable compatibility with such chassis. Meanwhile the card itself is not large and measures 27.7×13.1×4.36 cm.  

The board has four display outputs: two DisplayPort 1.4a, one HDMI 2.1, and one USB Type-C. It also supports the HDCP 2.3 technology for compatibility with content that uses it. 

The product relies on a custom-designed printed circuit board (PCB) with an enhanced voltage regulating module (VRM) that uses quality components like inductors, solid-state capacitors, and high-current power stages. The board features three eight-pin auxiliary PCIe power inputs that can deliver up to 450W of power and in the technical specs we note that Asus recommends an 850W PSU.

Traditionally for ROG Strix-badged products, the ROG Strix LC RX 6900 XT Top Overclocked Edition has numerous addressable RGB LEDs.

High out-of-box clocks and the 'unlocked' processor are the key selling points of the new ROG Strix LC RX 6900 XT Top Overclocked Edition graphics card as Asus has been formally offering an a Radeon RX 6900 XT with a hybrid cooling system for quite a while now.

Just like other makers of graphics cards these days, Asus does not talk about recommended pricing of its latest product since its real-world price tag will differ significantly from its MSRP.
