Performance to Rule Your Game The ASRock AMD Radeon RX 6600 Challenger D, is here to deliver the performance you deserve, boasting the latest PCI-e 4.0 support, Dual striped axial fan cooling solution a stylish metal backplate and 0dB silent cooling technology with maximum contact heatpipes and premium thermal pads, to ensure you can consistently reach the top tier performance required to climb those leaderboards. AMD Radeon™ RX 6600 Series graphics cards deliver serious 1080p gaming and ultra-high frame rates. Get up to 32 high-performance compute units, groundbreaking AMD Infinity Cache, and up to 8GB of dedicated GDDR6 memory. Experience the next gen of gaming performance with AMD Smart Access Memory technology1 when you pair an AMD Radeon™ RX 6600 Series graphics card with an AMD Ryzen™ 5000 Series desktop processor.
Designed for Enhanced Airflow
Striped Axial FansASRock's custom designed striped axial fan delivers peak performance by guiding airflow down the through the stripe structure to reduce air turbulence and ensure a more effective and efficient cooling process.
Stylish Metal Backplate
Not Just a Pretty FaceDesigned to reduce PCB flex, the all-metal vented backplate also enhances cooling dissipation and is equipped with high-performance thermal pads, as well as boosting the overall aesthetics of the GPU.
Super Alloy Graphics Card
DR MOSDr.MOS is the integrated power stage solution which is optimised 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 ChokeCompared 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 motherboard.
Nichicon 12K Black CapsSupreme 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 PCBUsing only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
Matte Black PCBA new mysterious matte black and copper color scheme to match the prestigious components on ASRock's high-end graphics card.
High Density Glass Fabric PCBHigh Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the graphics card against electrical shorts caused by humidity.
A Breakthrough Gaming Architecture
RDNA2 ArchitectureAMD RDNA™ 2 architecture is the foundation of next-generation gaming PCs and consoles. It is the bedrock of the upcoming revolution in PC gaming graphics and cloud gaming. AMD RDNA™ 2 elevates and unifies visual effects and gameplay across multi- gaming platforms, like no other graphics architecture before.
Contrast Adaptive SharpeningOFF
Contrast Adaptive SharpeningON
Bring Out All The DetailContrast Adaptive Sharpening (CAS) helps increase visual quality by enabling stunning visual sharpness with optional upscaling to restore detail lost after Temporal Anti-Aliasing (TAA) is applied. For games that support FidelityFX CAS, turning off Radeon™ Image Sharpening in Radeon™ Software to avoid over-sharpening is recommended.
Shading Rate OverlayOFF
Shading Rate OverlayON
Get Performance with QualityUsing RDNA2 architecture and variable rate shading allows fidelityFX to analyse luminance and motion of frames to help optimise rending to ensure you also get optimal performance without reducing image quality.
Realistic Geometry ShadingAMD RDNA™ architecture-optimized Combined Adaptive Compute Ambient Occlusion (CACAO) dynamically and efficiently helps improve the appearance of objects based their exposure to ambient light.
Screen Space ReflectionsOFF
Screen Space ReflectionsON
High-Quality Realistic ReflectionsAMD’s implementation of Stochastic Screen Space Reflections (SSSR) delivers high-quality reflections with minimal overhead via an optimised compute shader and AMD RDNA™ architecture-optimised denoising.
High-Quality Raytracing and EffectsDenoising optimised for AMD RDNA™ architecture to help improve the visual quality of real-time raytracing and other in-game effects.
High-Quality HDR GamingOptimised for use with AMD FreeSync™ Premium Pro1 displays, AMD's Luminance Preserving Mapper (LPM) delivers superb HDR and wide color gamut content.
