Description

• RDNA 3 Architecture & Chiplet Design: Utilizes a 5 nm compute die paired with 6 nm cache die chiplets, powered by 84 Compute Units (5,376 stream processors), and 168 AI Acceleration cores. Second-gen Infinity Cache delivers ~54 MB for high bandwidth efficiency.

• Clock Speeds: Game clocks around ~2,000 MHz and boost clocks up to ~2,400 MHz. Some partner models (e.g. XFX Quicksilver/MERC 310) reach higher speeds around 2,530 MHz.

• Memory & Bandwidth: 20 GB of GDDR6 memory (20 Gb/s) across a 320‑bit interface for roughly 800 GB/s bandwidth.

• Display Outputs: Typically includes 2× DisplayPort 2.1, 1× HDMI 2.1, and 1× USB‑C with DisplayPort support—enabling up to 8K at high refresh via DP2.1 rules.

• Power & Efficiency: Rated around 300–315 W TDP, requiring two standard 8‑pin PCIe power connectors. Despite high performance, efficiency remains relatively strong.

• Cooling & Size: Most partner cards use triple-fan coolers in a 2.5 to 3‑slot design. Reference cards suffered from thermal hotspots in early batches (up to 109 °C), prompting AMD to issue fixes and warranty replacements. Partner designs generally avoid these issues.

• Gaming Performance: Excels in 4K rasterized gaming—frequently matching or outperforming Nvidia RTX 4080 in many titles. However, it lags behind in ray tracing-heavy workloads and lacks mature DLSS-like support, relying on AMD FSR upscaling instead.
