This advanced thermal solution might be one reason why XFX chose to release this specific model relatively late in the life cycle of AMD's Radeon RX 7900 XTX and the Navi 31 graphics processor. This late launch allows XFX to evaluate the performance of the PTM7950 thermal pad in a real-world setting. If the results meet their standards, it could lead to broader application of this technology in future products, potentially giving XFX an edge in the competitive graphics card market. The XFX Radeon RX 7900 XTX Phoenix Nirvana is built on AMD's Navi 31 graphics processor and includes 6144 stream processors and 24 GB of memory. The GPU's clock speed reaches up to 2615 MHz, which, while not the highest in the industry, is competitive. For connectivity, the card offers three DisplayPort 2.1 connectors and one HDMI 2.0 connector, aligning it with common outputs found in other models of the Radeon RX 7900 XTX series. Currently available in China, the release schedule for Western markets remains unconfirmed, leaving potential buyers in those regions awaiting further announcements.
XFX Releases Radeon RX 7900 XTX Phoenix Nirvana with Phase-Change Thermal Pad
XFX recently introduced the Radeon RX 7900 XTX Phoenix Nirvana graphics card, notable for its innovative cooling design. This card incorporates a 3.5-slot cooling system and a phase-change material (PCM) thermal pad, which aims to enhance thermal management significantly. The Radeon RX 7900 XTX Phoenix Nirvana features a robust 17-phase digital voltage regulating module and is supported by three eight-pin auxiliary PCIe power connectors. These connectors are designed to supply up to 450W of power, enhancing the card's capacity for overclocking. With such a setup, users can push the graphics processor beyond its standard operational limits, potentially improving performance in demanding applications and gaming. The cooling system on this new model is extensive, featuring a vapor chamber, eight 6-mm heat pipes, and 216 aluminum fins, all integrated into its 3.5-slot design. A standout component of this system is the Honeywell PTM7950 thermal pad. Made from a phase-change material, this pad is engineered to provide superior thermal conductivity, effectively transferring heat away from the GPU to maintain optimal operating temperatures.
