Introduction
A QuickSilver Class Limited Edition - XFX introduced its Radeon RX 7800 XT Magnetic Air graphics card, featuring an innovative design with detachable, magnetically levitating fans. This latest model stands as the fastest in XFX's lineup, combining high performance with unique customization options. Right out of the box, the card is enhanced by the manufacturer to deliver optimal performance, showcasing not only its capability but also its striking appearance. This white edition in the 7800 XT series, this graphics card features a striking all-white design, including the PCB, heatsink, and cables. It has been specially modified at the factory to boost its cooling capabilities, ensuring it runs smoothly and quietly. This results in a slight performance increase of about 3%. Built for stability and efficient cooling, it's ideal for gamers looking for a reliable and powerful gaming experience. Additionally, it's priced competitively at $499, making it an attractive option for those looking to upgrade their setup.
The XFX Magnetic Air system offers a hassle-free solution for quickly swapping out fans on a graphics card, eliminating the need for tools or screws. This system utilizes powerful Neodymium Iron Boron (NdFeB) magnets, boasting a magnetic strength of 4000GS, strong enough to support weights up to 1kg. Impressively, these magnets maintain their strength over time, simplifying maintenance and servicing. The fans are designed for efficiency and performance. They feature 11 blades and can operate at speeds up to 3200 RPM. With a maximum airflow capacity of 70.08 cubic feet per minute (CFM) and an air pressure peak at 4.88 mmAq, they ensure effective cooling under high-performance demands.The cooling system is enhanced by a nickel-plated copper vapor chamber that serves both the GPU and DDR modules. This setup improves heat distribution and efficiency. Additionally, XFX strategically places thermal pads over all crucial components like GDDR, VRM, and the backside of the PCB. This design choice aids in managing heat dissipation effectively.A significant innovation is the use of Honeywell PTM7950 thermal interface material (TIM), which extends the period between maintenance needs due to its exceptional longevity and effectiveness. Furthermore, the incorporation of a two-phase vacuum heat transfer system marks a substantial upgrade over traditional cold plate methods, ensuring superior heat transfer capabilities. This advanced cooling technology, crafted from nickel-plated copper, underscores our commitment to providing robust and reliable thermal solutions for high-performance computing.
The Radeon 7800 XT graphics card, with a boost frequency of 2430 MHz and a total graphics power (TGP) of 212 watts, is designed to be efficient. This version of the card, which occupies three slots in a computer, can operate at slightly higher clock speeds than the standard model. It features two 8-pin power connectors to supply energy. The card comes with 16GB of memory across a 256-bit interface, running at a speed of 19.5 Gbps, which is impressive for handling complex graphics tasks. It utilizes the full capabilities of its architecture with 60 Compute Units (CUs) and 3840 shader processors, resulting in a total board power (TBP) of 263 watts. This makes the Radeon RX 7800 XT a robust choice for gamers and professionals. Based on the Navi 32 SKU architecture, the GPU includes advanced components like four Memory Controller Domains (MCDs). It features 3840 cores, strategically distributed across the 60 CUs to maximize performance. The GPU also includes a significant 64 MB of Infinity Cache, which operates at 19.5 Gbps. This setup provides an impressive total memory bandwidth of 576 GB/s, enhancing the card’s ability to handle data-intensive applications efficiently. This blend of features makes the Radeon 7800 XT a robust option for those requiring very decent graphic processing capabilities.
