  • Memory TypeGDDR6
  • 16 GB GDDR6 memory fuels high-resolution gaming
  • Boost clock reaches 2360 MHz for responsive frame rates
  • 4608 stream processors handle demanding workloads
  • HDMI 2.1 plus three DisplayPort 1.4 outputs drive four displays
  • PCI Express 4.0 interface doubles bandwidth over earlier versions

Sapphire Nitro+ RX 6800 XT 16GB

The Sapphire Nitro+ Radeon RX 6800 XT is a PCIe 4.0 graphics card built on AMD RDNA 2 architecture for high-frame-rate gaming at 1440p and 4K. It targets enthusiasts who want factory-overclocked performance with a robust triple-fan cooler. The card requires a minimum 850W power supply and two 8-pin connectors.

16GB 256-Bit GDDR6 capacity and headroom

Sixteen gigabytes of GDDR6 memory on a 256-bit bus running at 16 Gbps give ample buffer for modern titles at ultra settings and high-resolution texture packs. The 4608 stream processors and 2360 MHz boost clock deliver strong rasterisation throughput. Memory bandwidth becomes the limiting factor before compute in heavily bandwidth-bound scenarios.

Thermals noise and 350W power draw

A triple-fan cooling assembly manages the 350W thermal design power under sustained gaming loads. Fan curves are tuned to balance airflow with acoustic output during typical sessions. Power is delivered through dual 8-pin connectors drawing from the 12V rail. The card exhausts heat into the chassis, so case airflow must be sufficient.

Questions about this item

Will the PCI Express 4.0 interface on this Nitro+ RX 6800 XT work in my older PCIe 3.0 motherboard slot?

The card uses a PCI Express 4.0 x16 connection and is backward compatible with PCIe 3.0 motherboards. It will run at PCIe 3.0 speeds in an older slot without any configuration changes.

How can I verify the 2360 MHz boost clock is active after installing the drivers?

Open the AMD Radeon Software performance overlay or a third‑party monitor like GPU‑Z. Under load the core frequency should reach 2360 MHz and the 16GB GDDR6 memory should show 16 Gbps effective clock.

Does the box include the two 8‑pin power cables or do I need to buy them separately?

The card requires two 8‑pin PCIe power connectors. Those cables come from your power supply, not the graphics card box. Ensure your PSU has both connectors or includes the necessary adapters.
