ASRock Radeon RX 6600 Challenger D Graphics Card

The ASRock Radeon RX 6600 Challenger D delivers reliable 1080p gaming performance with 8GB GDDR6 memory and AMD's RDNA 2 architecture. Built on a 7nm process with 1792 stream processors, this graphics card provides the power needed for modern gaming at high settings.

Performance Specifications

This graphics card features three clock configurations to balance performance and efficiency. The boost clock reaches up to 2491 MHz for demanding workloads, while the game clock operates at 2044 MHz for sustained gaming sessions. The base clock of 1626 MHz ensures stable operation, paired with 14 Gbps memory speed across a 128-bit interface.

Dual Fan Cooling System

The Challenger D utilizes a dual fan design with striped axial fans that enhance airflow through structured blade design and polished undersides. The 0dB silent cooling technology stops the fans during low temperatures for silent operation, spinning up only when cooling is required. Ultra-fit heatpipes maximize contact with the copper base for efficient heat transfer from the GPU.

A metal backplate prevents PCB bending while adding structural rigidity. Premium thermal pads on the backside assist with heat dissipation from memory and VRM components. ASRock applies precise screw torque during assembly to optimize mounting pressure without risking GPU damage.

Display Connectivity

The RX 6600 Challenger D supports up to four displays simultaneously with three DisplayPort 1.4 outputs featuring Display Stream Compression and one HDMI 2.1 port with Variable Refresh Rate support. Maximum digital resolution reaches 7680 x 4320, providing flexibility for multi-monitor configurations.

Technical Features

DirectX 12 Ultimate support enables hardware-accelerated ray tracing and variable rate shading. The PCIe 4.0 interface provides maximum bandwidth for data transfer. A single 8-pin power connector supplies the card, with a recommended 500W PSU for system stability. The compact dimensions of 269 x 132 x 41 mm and 627g weight make it compatible with most mid-tower cases.

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.

Nano Thermal Paste
Perfect Thermal Teamwork.
Eliminate the gaps in the contact area to maximize heat transfer and thermal efficiency.

Premium Thermal Pad
Better Heat Transfer.
The premium thermal pad helps to transfer the heat of the components to the heatsink, improving heat dissipation.

Precise Screw Torque
Optimized Mounting Pressure.
ASRock adopts precise screw torque when assembling its graphics cards to optimize the cooler mounting pressure to improve thermal efficiency while avoiding damage to GPU die.
