New Radeon RX 7900 Passive Series: High Performance, Quiet Cooling for Servers and Enthusiasts
The latest ASRock Radeon RX 7900 Passive graphics cards come with a substantial aluminum radiator that features an evaporative chamber. This design delivers effective passive cooling without relying on active fans, making it well suited for compact server racks and specialized computing environments where silence and reliability matter. Both models in the line are capable of parallel GPU operation, enabling use in multi-GPU configurations where space is at a premium and performance demands are high.
Radeon RX 7900 XTX Passive 24 GB
- 96 execution units
- 96 MB AMD Infinity cache
- Frequency up to 2500 MHz
- 24 GB GDDR6 memory with a 384-bit bus
The XTX variant is engineered for demanding workloads, combining a robust number of execution units with a large cache and fast memory. Its expansion to 24 GB of GDDR6 memory ensures smooth handling of memory-intensive tasks, such as high-resolution rendering, complex simulations, and data-heavy workloads in professional environments. The thermal solution is designed to maintain steady performance under sustained load, while the compact form factor allows easier integration into dense system units. This model is particularly appealing to builders who require silent operation without compromising compute power. Source VG Times.
Radeon RX 7900 XT Passive 20 GB
- 84 execution units
- 80 MB AMD Infinity cache
- Frequency up to 2395 MHz
- 20 GB GDDR6 memory with a 320-bit bus
The XT variant balances core count, cache, and memory bandwidth to deliver strong gaming and creator performance in a passive cooling package. With 20 GB of GDDR6 and a 320-bit memory interface, it handles modern titles and professional workflows with ease, while the radiator design keeps temperatures stable even during prolonged sessions. The dual-slot, compact 261 mm length make it compatible with a wide range of compact chassis and workstation builds, and the absence of active fans ensures a quiet operation that is ideal for home studios, labs, and small data rooms. The backplate reinforces rigidity and helps with overall durability in transport-ready systems. For display connectivity, three DisplayPort 2.1 outputs and one HDMI 2.1 output are provided, and power is supplied via a single 12V 2×6 connector on the right edge of the PCB. This configuration supports flexible multi-monitor setups and straightforward cabling in tight spaces. Source VG Times.
Both models feature a robust metal reinforcement plate on the rear for extra rigidity and a secure mounting experience. The radiator includes a distinctive V-shaped cutout at the end, designed to improve cooling efficiency for critical components. This thoughtful detail is part of what makes these passive units appealing to enthusiasts who pursue liquid cooling enthusiasts’ aesthetics and performance. The design accommodates a water block swap, enabling users who rely on custom cooling loops to upgrade without changing the core card. In practice, this combination of passive cooling with optional water cooling presents a compelling option for professional systems, gaming rigs, and hobbyist builds that demand quiet operation with strong graphical throughput. The cards are positioned for computer system makers and performers who value both silence and high compute density, offering a versatile path from standard air cooling to advanced liquid cooling configurations.
