AMD Radeon RX 6800 XT Graphics Card (16GB GDDR6) PowerColor

Product Overview

The AMD Radeon RX 6800 XT stands as a flagship-tier graphics card built on the revolutionary RDNA 2 architecture, manufactured on TSMC's 7nm process. Designed for enthusiasts targeting high-refresh 1440p and entry-level 4K gaming, this GPU delivers 4608 stream processors across 72 compute units, backed by a massive 16GB GDDR6 frame buffer on a 256-bit bus. The generous VRAM allocation ensures headroom for modern titles with high-resolution texture packs, while the 128MB Infinity Cache dramatically reduces latency and boosts effective memory bandwidth to 512 GB/s without requiring a wider, more expensive bus.

With a game clock of 2015 MHz and boost clocks reaching 2250 MHz, the RX 6800 XT sustains high frequencies under typical gaming loads. The 300W total board power draws from dual 8-pin connectors, requiring a quality 750W power supply. This thermal envelope allows the card to maintain performance in extended sessions, while PCI Express 4.0 x16 support ensures maximum throughput on compatible platforms. Whether you're pushing high frame rates in competitive shooters or immersing yourself in ray-traced single-player epics, the RX 6800 XT delivers the raw compute and memory capacity to handle both rasterization and hybrid rendering workloads.

Beyond gaming, the 16GB VRAM and compute throughput make this card viable for content creation tasks such as video editing, 3D rendering, and AI inference workloads that benefit from large memory pools. Hardware-accelerated AV1 decode future-proofs media playback, while support for up to four simultaneous displays via two DisplayPort 1.4 outputs, one HDMI 2.1 port, and one USB Type-C connector enables flexible multi-monitor setups for productivity or simulation rigs.

Key Features & Hardware Capabilities

• Architecture & Execution Units: RDNA 2 architecture on 7nm process with 72 Compute Units, 4608 Stream Processors, 288 Texture Mapping Units, and 128 Render Output Units. Includes 72 Ray Accelerators for hardware-accelerated ray tracing and 128MB Infinity Cache for reduced memory latency and higher effective bandwidth.
• Memory Subsystem: 16GB GDDR6 memory running at 16 Gbps effective across a 256-bit interface, delivering 512 GB/s peak bandwidth. The 128MB Infinity Cache acts as a high-speed last-level cache, significantly improving cache hit rates and reducing VRAM accesses in gaming workloads.
