Sapphire Tech Pulse Radeon RX 6800 16GB GDDR6 graphics card 11305-02-20G

Pulse RX 6800 16GB GDDR6

The Sapphire Pulse Radeon RX 6800 delivers 16GB of GDDR6 memory on a 256-bit bus for 1440p and 4K gaming. A game clock of 1950 MHz and boost clock of 2170 MHz drive 3840 stream processors through the PCI Express 4.0 interface. The triple-fan cooler handles the 280W thermal design power while the card fits a standard x16 slot with two 8-pin power connectors. It suits builders who want high frame rates at 1440p or entry 4K without stepping to a larger flagship.

Upgrade from 8GB or older RDNA cards

Moving from an 8GB model or an earlier RDNA architecture card adds 16GB of VRAM and the higher boost clock of 2170 MHz. The jump is worth it when texture packs, mods or higher resolution textures push past 8GB limits in current titles. A 650W power supply and two 8-pin connectors are the minimum platform requirements to support the 280W board power. DirectX 12 support and 4K60 output over HDMI 2.1 complete the feature set for modern displays.

16GB VRAM headroom for 1440p ultra and 4K entry

The 16GB frame buffer and 256-bit interface comfortably handle ultra texture settings at 1440p and playable 4K in most modern engines. Memory bandwidth at 16 Gbps effective clock keeps the 3840 stream processors fed in raster workloads. Headroom narrows when heavy ray-tracing workloads or extreme 4K texture packs exceed the available VRAM or memory bandwidth. For pure raster gaming at 1440p the capacity remains generous for the foreseeable future.
