The Nitro+ features a triple-fan cooler set within a 3-slot design and is powered by dual 8-pin PCIe connectors. For connectivity, it offers 3x DisplayPort 2.1 outputs and 1x HDMI 2.1 output. Leveraging AMD's Radiance Display engine, which supports DisplayPort 2.1, the card can achieve frame rates up to 480Hz in 4K and 165Hz in 8K. While not every user might utilize this high frame rate capability, AMD's decision to include the display connector provides a clear contrast to Nvidia's omission in their RTX 4000 series. The Sapphire RX 7800 XT Nitro+ version features a Boost Clock setting of 2565 MHz. This edition employs a cooler that is more expansive than its predecessors, spanning beyond three slots. It's equipped with an ARGB strip, positioned at the top, which can be adjusted using the Sapphire TRIXX software. The Nitro+ includes features like a dual BIOS switch and is powered through three 8-pin PCIe ports. In terms of connectivity, it offers two HDMI 2.1 ports and two Display 2.1 ports at the rear. This configuration indicates that the Sapphire Nitro+ model utilizes a distinct PCB design that deviates from the standard board.
In the Vapor-X Cooling system, the primary GPU chip and GDDR6 Memory are strategically placed to ensure direct contact with the Vapor Chamber. This design promotes uniform heat transfer across the surface of the Vapor-X module, allowing for more efficient heat dissipation compared to conventional copper heat sinks. The process directs the heat-laden component toward the Vaporization Chamber. Within this vacuumed chamber, both working fluid and pure water are promptly vaporized. This vapor then travels to the Condensing Wick located near a cooled surface. Once there, it reverts to a liquid state and is subsequently channeled back to the Vaporization Wick through capillary action. This cycle, where the liquid is reheated and re-vaporized by the heat source, constitutes the Vapor-X Cooling mechanism. It operates as a continuous liquid recycling system.
The Radeon RX 7800 XT is equipped with 16GB/256-bit dedicated memory, suitable for contemporary games and graphic-heavy applications. We have reviewed a reference model from AMD. Central to the Radeon RX 7800 XT is the RDNA 3 GPU architecture from AMD, which offers enhanced performance, power efficiency, and features relative to earlier versions.
Both the Radeon RX 7700 XT and 7800 XT offer diverse connectivity options, featuring 3x DisplayPort 2.1 and 1x HDMI 2.1 outputs. With AMD's Radiance Display engine, the card supports DisplayPort 2.1, enabling frame rates as high as 480Hz in 4K and 165Hz in 8K.
The 236W TGP-rated graphics card necessitates a dual 8-pin power connector and is equipped with a 3-slot design tripple-fan cooler. The reference card has a closed backplate.
