Sapphire Nitro+ Radeon RX 6800 XT Review

Sapphire Nitro+ Radeon RX 6800 XT is a high-end AMD graphics card built on the RDNA 2 (Navi 21) architecture, with 16GB of GDDR6 memory, a 2310MHz boost clock, and a 300W TDP. It is RDNA 2's high-end 4K card, still a capable 1440p/4K performer.

If you're shopping for a high-end card, the Sapphire Nitro+ Radeon RX 6800 XT lines up against NVIDIA's GeForce RTX 3080 in this catalog. Expect a card around 286mm long needing a 2.5-slot opening in your case, with stream processors count of 4608 feeding its rendering pipeline. Launch MSRP was $649, though street pricing has moved since.

Performance and Architecture

Built on AMD's RDNA 2 (Navi 21) architecture, the Sapphire Nitro+ Radeon RX 6800 XT pairs 4608 stream processors with 16GB of GDDR6 memory on what AMD rates as a 2310MHz boost clock. That combination places it in the high-end tier, where it's tuned for a specific resolution and refresh-rate target rather than being a universal do-everything card.

Power, Size, and Compatibility

At a 300W TDP, the Sapphire Nitro+ Radeon RX 6800 XT needs a power supply with enough headroom on the 12V rail plus whatever PCIe power connectors this variant uses. Physically it runs about 286mm long and occupies a 2.5-slot opening, so measure your case's GPU clearance and front intake fans before buying, especially in compact builds.

Comparison to Alternatives

The closest rival to the Sapphire Nitro+ Radeon RX 6800 XT in this catalog is NVIDIA's GeForce RTX 3080, which competes at a similar price and resolution target. Shoppers who need more VRAM headroom or lower power draw than the Sapphire Nitro+ Radeon RX 6800 XT offers should cross-shop that card before deciding, since the two trade blows depending on the game engine and whether ray tracing or upscaling is in use.
