Yeston and GravaStar have announced their latest graphics card, the Radeon RX 9070 XT Mercury Nova OC. This new model brings a combination of factory overclocking, distinctive design, and an advanced cooling system aimed at high-performance users.
The Mercury Nova OC features a unique chassis built around a three-dimensional steel skeleton. This design, which Yeston and GravaStar describe as influenced by “alien biomimicry,” provides structural strength and also creates airflow channels to improve cooling efficiency. The backplate is CNC-machined and includes asymmetrical flowing patterns that assist in directing airflow and dispersing heat.


Lighting is handled by a multi-zone ARGB system. Unlike simpler implementations that use a single lighting zone, this design splits the card into multiple sections, each of which can display independent colors and effects. Users can configure these zones to respond to GPU temperature or apply custom patterns using GravaStar’s software.
Cooling performance is supported by a hybrid system. The card includes a vapor chamber that spreads heat quickly from the GPU core to surrounding components. Seven 6 mm heat pipes then transfer this heat to a dense array of aluminum fins. Cooling air is provided by three 93 mm fans equipped with dual-ball bearings for improved durability and reduced noise. Under typical gaming loads at 1440p and 4K, the fans remain under 40% of their maximum speed, keeping noise levels moderate.


Out of the box, the Mercury Nova OC operates at a boost clock of up to 3,060 MHz, which is 90 MHz higher than the AMD reference specification for the RX 9070 XT. This is made possible by a reinforced 12-layer PCB that includes upgraded MOSFETs and high-efficiency capacitors. These improvements provide additional headroom for manual overclocking through Radeon Software or third-party utilities.
Benchmark data from third-party reviewers shows modest but consistent gains in demanding titles. For example, in “Cyberpunk 2077” at Ultra settings and 1440p, the Mercury Nova OC achieved an average frame rate of 75 fps, compared to 68 fps for the reference RX 9070 XT.


GravaStar’s software package is required to manage ARGB lighting and fan profiles. It also provides real-time monitoring of GPU temperature, clock speeds, and power usage. The software is compatible with Windows, while Linux users can access standard GPU functionality through AMD’s open drivers. Lighting control on Linux is limited to open-source tools that interact with the card’s ARGB controller.
The Radeon RX 9070 XT Mercury Nova OC will be available soon through Yeston and GravaStar’s retail partners. Pricing and release dates are expected to be announced in the coming weeks.
