At the core of the NITRO+ Graphics Cards series are the technologies of the SAPPHIRE PANTHEON Suite ofpermanent features. SAPPHIRE PANTHEON guarantees supreme cooling technology and other distinctfeatures exclusive to NITRO+ graphics cards. Each NITRO+ iconic feature stands as strong and permanent asthe pillars of the PANTHEON. Every NITRO+ Graphics Card guarantees the presence of the stable, reliableand innovative SAPPHIRE PANTHEON suite of features.
The NITRO+ AMD Radeon™ RX 7900 Vapor-X Series Graphics Cards are fitted out with the iconic Vapor-XCooling. The Vapor Chamber is mounted in contact with the surface of the GPU and GDDR6 Memory. TheVapor-X cooler is fine-tuned to work with the other cooling components such as the fins, heatpipes and fansto bring the best efficiency to cool the GPU and components. Since the entire area transfers heat at thesame rate, the Vapor-X module is engineered to work more efficiently than a copper heat sink at carryingaway heat. Upon gaining heat, the heat source is pushed to the Vaporization Wicks to begin the heatdissipation process. Due to extreme low pressure, working fluid and pure water are easily vaporized andmoved through the vacuum until it reaches the Condensing Wick which is adjacent to the cooled surface. Atthis point, the vapor turns back to a liquid state whereby the liquid is then absorbed by the TransportationWick by capillary action and moved back towards the Vaporization Wick. A recycled liquid system occurswhen the heat source reheats the liquid and it becomes re-vaporized by the Vaporization Wick to restart theVapor-X Cooling process. The Optimized Composite Heatpipes work in tandem with Vapor-X Cooling, fine-tuned for the cooling design, with optimal heat flow to efficiently and evenly spread out the heat to theentire cooling module.
On NITRO+ AMD Radeon™ RX 7900 XTX Vapor-X, 90 Ampere Mosfets for GPU with 12 phases is engineeredonto the board. This digital power design provides a total of 1080 Ampere currents to the GPU, offering28% more power delivery for the GPU in comparison to the standard AMD Radeon™ RX 7900 XTX design, topush maximum overclocking potential.
The NITRO+ AMD Radeon™ RX 7900 Series Vapor-X Graphics Cards are constructed with a Die CastedAluminum-Magnesium Alloy Frame that strengthens the structural stiffness of the shroud and ensuresdurability whilst enveloping the sides of the PCB. Located on top of the frame is the Frontplate Heatsinkwhich overlays the entire PCB to cool the VRM components as a dedicated VRM cooling module to createoptimal heat dissipation for peak airflow and cooling performance.
