XFX Quicksilver Radeon RX 9070 XT Gaming Edition

Manufacturer: XFX

The XFX Quicksilver Radeon RX 9070 XT Gaming Edition is a desktop graphics card based on AMD's RDNA 4.0 architecture, fabricated on a 4 nm process and housing 53,900 million transistors. It features 48.66 TFLOPS of floating-point performance alongside a boost clock of 2970 MHz, making it a technically capable option within its product generation. The card carries a TDP of 304W, connects via PCIe 5.0, and includes RGB lighting as part of its physical design.

On the memory side, the card is equipped with 16GB of GDDR6 VRAM across a 256-bit bus, delivering a maximum bandwidth of 640 GB/s at an effective speed of 20,000 MHz. It supports AMD SAM, ray tracing, FSR4, and DirectX 12 Ultimate, while also being compatible with OpenGL 4.6 and OpenCL 2.2. Display output options include one HDMI 2.1b port and three DisplayPort outputs, supporting up to four displays simultaneously. The card measures 350 mm in length and 140 mm in height, and carries a three-year warranty.

Pros
  • Supports up to four simultaneous displays via one HDMI 2.1b port and three DisplayPort outputs
  • 16GB of GDDR6 VRAM with a 256-bit bus provides a substantial frame buffer for memory-intensive workloads
  • FSR4 upscaling and ray tracing support are both included
  • AMD SAM is supported, enabling the CPU to access the full GPU memory pool directly
  • ECC memory support adds data integrity for workloads that require error correction
  • Comes with a three-year warranty
Cons
  • A 304W TDP demands a capable power supply and adequate case airflow
  • DLSS and XeSS are not supported, limiting upscaling options to FSR4 only
  • No USB-C video output is available
  • Water-cooling is not supported; the card relies solely on air cooling
  • The 350 mm length may present fitment challenges in smaller or mid-tower cases
Who is this for?

This card is a solid fit for users who run demanding gaming or creative workloads that benefit from a large frame buffer, as the 16GB of GDDR6 VRAM with 640 GB/s bandwidth handles memory-intensive tasks with room to spare. The inclusion of ray tracing, FSR4, and DirectX 12 Ultimate support makes it well-suited for modern titles that leverage these rendering features. It also works well for users who need multi-display setups, with four simultaneous outputs and support for HDMI 2.1b, and for those running compute or professional tasks that can take advantage of OpenCL 2.2 and ECC memory support.

Who is this NOT for?

The 304W TDP makes this card a poor match for users with entry-level or lower-capacity power supplies, or those building in compact cases where thermal headroom is limited — the 350 mm length alone rules out many small form-factor builds. Users who rely on DLSS or XeSS upscaling within their existing workflow will find those options unavailable here, as only FSR4 is supported. Additionally, the absence of a USB-C video output makes it unsuitable for users whose monitors or capture setups depend on that connection type.

Final Verdict

The XFX Quicksilver Radeon RX 9070 XT Gaming Edition brings together a well-rounded specification set built around AMD's RDNA 4.0 architecture, with 16GB of GDDR6 VRAM and 640 GB/s of memory bandwidth forming the backbone of its capability for demanding workloads. Ray tracing, FSR4, DirectX 12 Ultimate, and ECC memory support round out a feature set that covers both modern gaming and compute use cases. Its power draw and physical dimensions mean it requires a suitably capable system to operate at its best, and users tied to specific upscaling ecosystems may find its FSR4-only support a limiting factor. For those building or upgrading a system that can accommodate it, this card represents a technically complete offering within its generation.
