ASRock Radeon RX 6600 Challenger D, graphics card (RDNA 2, GDDR6, 3x DisplayPort, 1x HDMI 2.1)

Dual Fan Design
Two fans that provide strong cooling performance and make your gaming rig stay cool. It’s optimized for delivering excellent gaming experience with stylish and streamlined design.

Stylish Metal Backplate
Solid, Fancy, Cool.
Designed to avoid PCB bending. The fancy outlook makes the graphic card more legendary in visual. It also helps to enhance cooling with the premium thermal pads equipped backside.

Striped Axial Fan
Designed For Enhanced Airflow.
ASRock’s custom Striped Axial Fan delivers enhanced airflow to optimize cooling from not only the stripe structure on each fan blade but also the polishing surface on the bottom side.

0dB Silent Cooling
Spin For Cooling, Stop For Silence.
The fan spins when the temperature goes high for the optimal cooling, and stops when the temperature goes low for the complete silence.

Ultra-fit Heatpipe
Consolidated to Maximize the Contact.
The heatpipes are consolidated to maximize the contact among each others and also the GPU baseplate for the optimized heat dissipation.

Copper Base
Maximize GPU Contact Area.
With premium copper base heatsink design, the direct contact area to the GPU would be maximized to improve thermal transfer effectively.

Dr. MOS
Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Intelligently delivering higher current and driving up to 50A continuous current for each phase, thus providing improved thermal result and superior performance.

Premium 90A Power Choke
Compared to traditional chokes, ASRock’s premium 90A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the graphics card.

Nichicon 12K Black Caps
Supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Black Caps that offer 20% longer lifespans and provide more stability and reliability.

2oz Copper PCB
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.

Matte Black PCB
A new mysterious matte black and copper color scheme to match the prestigious components on ASRock's high-end graphics card.

High Density Glass Fabric PCB
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the graphics card against electrical shorts caused by humidity.
