Sapphire Nitro+ Radeon RX 7900 XTX Review

Sapphire Nitro+ Radeon RX 7900 XTX is a flagship AMD graphics card built on the RDNA 3 (Navi 31) architecture, with 24GB of GDDR6 memory, a 2565MHz boost clock, and a 355W TDP. It is AMD's RDNA 3 flagship, a 24GB chiplet-based card that undercuts NVIDIA's high-end pricing.

If you're shopping for a flagship card, the Sapphire Nitro+ Radeon RX 7900 XTX lines up against NVIDIA's GeForce RTX 4080 Super in this catalog. Expect a card around 320mm long needing a 2.5-slot opening in your case, with stream processors count of 6144 feeding its rendering pipeline. Launch MSRP was $999, though street pricing has moved since.

Performance and Architecture

Built on AMD's RDNA 3 (Navi 31) architecture, the Sapphire Nitro+ Radeon RX 7900 XTX pairs 6144 stream processors with 24GB of GDDR6 memory on what AMD rates as a 2565MHz boost clock. That combination places it in the flagship 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 355W TDP, the Sapphire Nitro+ Radeon RX 7900 XTX needs a power supply with enough headroom on the 12V rail plus whatever PCIe power connectors this variant uses. Physically it runs about 320mm 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 7900 XTX in this catalog is NVIDIA's GeForce RTX 4080 Super, 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 7900 XTX 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.
