XFX Quicksilver Radeon RX 9070 OC Gaming Edition

Manufacturer: XFX

The XFX Quicksilver Radeon RX 9070 OC Gaming Edition is a graphics card designed around AMD's RDNA 4.0 architecture, manufactured on a 5 nm process node and housing 53,900 million transistors. It carries a base GPU clock of 1440 MHz with a turbo frequency reaching up to 2700 MHz, and the card is rated at a TDP of 220W, making thermal management a relevant consideration for system builders.

On the memory side, the card is equipped with 16GB of GDDR6 running across a 256-bit bus at an effective speed of 20,000 MHz, delivering up to 640 GB/s of bandwidth. It supports DirectX 12 Ultimate and OpenGL 4.6, and includes hardware ray tracing alongside AMD FSR4 upscaling. The card offers 3,584 shading units, 224 TMUs, and 128 ROPs, yielding a pixel rate of 345.6 GPixel/s and a texture rate of 604.8 GTexels/s. Display output consists of one HDMI 2.1b port and three DisplayPort outputs, supporting up to four displays simultaneously, and the card connects via PCIe 5.0 and comes with a three-year warranty.

Pros
  • 16GB of GDDR6 VRAM across a 256-bit bus provides a substantial memory pool for demanding workloads
  • Hardware ray tracing support is included out of the box
  • AMD FSR4 upscaling is available, offering an in-house alternative to other upscaling solutions
  • ECC memory support adds a layer of data integrity useful for compute tasks
  • Four simultaneous display outputs are supported through a combination of one HDMI 2.1b and three DisplayPort connections
  • RGB lighting is built in for users who value visual customization of their build
Cons
  • A 220W TDP places a notable power draw demand on the system and PSU
  • No water-cooling or hybrid air-water cooling option is included
  • DLSS and XeSS upscaling are not supported, limiting upscaling choices to AMD FSR4 only
  • The card's length of 355 mm may present fitment challenges in smaller or mid-tower cases
  • No USB-C or DVI outputs are available, which may limit compatibility with certain older or specialized displays
Who is this for?

This card is well-suited to users who work with high-resolution, multi-display setups, given its support for up to four simultaneous outputs and generous 16GB of GDDR6 VRAM. Those running compute-intensive tasks alongside graphics work will appreciate the inclusion of ECC memory support and Double Precision Floating Point capability. Builders who want a feature-complete AMD-based system will also find value in native AMD SAM support, hardware ray tracing, and FSR4 upscaling, all of which integrate well within an AMD-centric platform.

Who is this NOT for?

Users working within compact or small-form-factor cases may find the card's 355 mm length a limiting factor, as fitment in tighter enclosures can be problematic at that size. Those who rely on DLSS or XeSS upscaling — common in NVIDIA or Intel-oriented workflows — will not find support for either technology here. Additionally, systems with a limited power supply headroom may struggle to accommodate the 220W TDP without upgrades, making this card a poor fit for low-wattage or energy-constrained builds.
