Sapphire Nitro+ RX 6900 XT 16GB

The Sapphire Nitro+ Radeon RX 6900 XT is a high-end graphics card built on the AMD RDNA 2 architecture. It features 16GB of GDDR6 memory across a 256-bit interface and 5120 stream processors. The card targets enthusiasts seeking 4K gaming performance and content creators needing substantial VRAM. It connects via a PCI Express 4.0 interface.

Installation and Clearance Notes

The card uses a triple-fan cooler and requires a PCI Express 4.0 x16 slot. A minimum 850W power supply is specified to handle the 363W thermal design power. Ensure the case length accommodates a full-size triple-slot design and that the power supply includes sufficient 8-pin connectors. Driver support covers Windows 10, Windows 11, and Linux 64-bit.

Ideal for 4K and VR Workloads

This model suits gamers targeting high refresh rates at 4K resolution or users driving multiple displays up to 7680 x 4320. The HDMI 2.1 and three DisplayPort 1.4 outputs support modern VR headsets and high-resolution monitors. Buyers with power supplies below 850W, compact cases, or older PCIe 3.0 platforms should consider less demanding alternatives.

Questions about this item

How can I confirm the card is running at its rated 2365 MHz boost clock after installation?

Use GPU monitoring software to observe the core frequency under load; it should reach 2365 MHz when the driver applies the factory OC profile.

What accessories are included in the box and what must I supply myself?

The package contains the triple-fan graphics card and documentation; you must provide an 850 W or higher power supply with the required PCIe power connectors and a motherboard with a PCI Express 4.0 x16 slot.

Which specification should I check to decide between available versions of this model?

Compare the boost clock figure — this NITRO+ SE Gaming OC variant is factory set to 2365 MHz, while other RX 6900 XT versions may run at lower speeds.
