XFX Quicksilver Radeon RX 7800 XT Magnetic Air

Manufacturer: XFX

The XFX Quicksilver Radeon RX 7800 XT Magnetic Air is a desktop graphics card built on AMD's RDNA 3.0 architecture and manufactured using a 5 nm process. It ships with 16GB of GDDR6 VRAM across a 256-bit memory bus, placing it in a segment suited to demanding workloads and high-resolution gaming. The card uses air cooling, carries a 263W TDP, and measures 337 mm in length and 132 mm in height, making it a full-sized card that will require attention to case compatibility. A 3-year warranty is included.

On the performance side, the GPU runs at a base clock of 1295 MHz and boosts up to 2430 MHz, delivering 37.32 TFLOPS of floating-point performance alongside a pixel rate of 233.3 GPixel/s and a texture rate of 583.2 GTexels/s. Memory bandwidth reaches 624 GB/s at an effective speed of 19,500 MHz, and ECC memory is supported. The card is compatible with DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 2.2, and supports ray tracing, stereoscopic 3D, and AMD SAM. For display output, it provides three DisplayPort and one HDMI 2.1 port, supporting up to four simultaneous displays. DLSS and XeSS are not supported, and there is no RGB lighting or USB-C output.

Pros

16GB of GDDR6 VRAM across a 256-bit bus provides substantial frame buffer capacity for high-resolution and memory-intensive workloads
Memory bandwidth of 624 GB/s supports fast data throughput for both graphics and compute tasks
DirectX 12 Ultimate and ray tracing support enable compatibility with modern rendering features
AMD SAM support allows compatible systems to access the full VRAM for potential performance gains
ECC memory support adds data integrity for users running compute or professional workloads
A 3-year warranty offers meaningful coverage for a discrete graphics card

Cons

A 263W TDP places significant demands on system power supplies and case airflow
At 337 mm in length, the card requires careful compatibility checks with smaller or mid-tower cases
No DLSS or XeSS support limits upscaling options to AMD-native solutions only
The absence of a USB-C output restricts direct connectivity to certain VR headsets and USB-C monitors
No water-cooling option is available, leaving thermal management entirely dependent on the air cooler

Who is this for?

This card is well-suited to users running high-resolution gaming or compute workloads that benefit from a large VRAM buffer, where the 16GB of GDDR6 and 624 GB/s of memory bandwidth provide meaningful headroom. The support for ray tracing, DirectX 12 Ultimate, and AMD SAM makes it a capable choice for users on compatible AMD platforms who want access to modern rendering features without compromise. Its four display outputs and multi-display support also make it a practical fit for users who need to drive up to four monitors simultaneously, whether for productivity or immersive setups.

Who is this NOT for?

Users working within tight power or thermal constraints will find the 263W TDP a limiting factor, as it demands a robust power supply and well-ventilated case to operate stably. The card's 337 mm length makes it unsuitable for compact or smaller form-factor builds where physical clearance is restricted. Additionally, users who rely on DLSS or XeSS upscaling as part of their workflow or gaming setup will find no support for either technology here, and the lack of a USB-C output may be a drawback for those using USB-C monitors or certain VR devices.
