Asus Dual GeForce RTX 4070 Super

Manufacturer: Asus

The Asus Dual GeForce RTX 4070 Super is a mid-to-high-range graphics card from Asus, based on Nvidia's Ada Lovelace architecture and manufactured on a 5 nm process node. It carries 35,800 million transistors and operates with a base clock of 1980 MHz, reaching a boost clock of 2475 MHz under load. The card supports ray tracing, DLSS, and RGB lighting, and can drive up to four displays simultaneously.

On the memory side, the card is equipped with 12GB of GDDR6X VRAM running across a 192-bit bus at an effective speed of 21,000 MHz, yielding a maximum bandwidth of 504.2 GB/s. With 7168 shading units, 224 texture mapping units, and 80 render output units, it delivers a texture rate of 554.4 GTexels/s and a floating-point throughput of 35.48 TFLOPS. Connectivity includes one HDMI 2.1a port and three DisplayPort outputs, while the card draws up to 225W TDP and interfaces with the host system via PCIe 4.0. Intel Resizable BAR is supported, and ECC memory capability is present. Physical dimensions come in at 267 mm in length and 133.9 mm in height.

Pros
  • Supports up to four displays simultaneously, offering flexible multi-monitor setups
  • HDMI 2.1a and three DisplayPort outputs cover a wide range of modern display connections
  • GDDR6X memory with 504.2 GB/s bandwidth enables fast data throughput for demanding workloads
  • ECC memory support adds data integrity for compute-oriented tasks
  • DLSS and ray tracing are both supported, enabling advanced rendering features
  • RGB lighting is included for users who want visual customization
Cons
  • The 192-bit memory bus is narrower than what higher-end cards in this category typically offer
  • No USB-C output is available, limiting compatibility with certain displays and adapters
  • Air-water cooling is not supported, restricting thermal management options to air cooling only
  • 12GB of VRAM may become a limiting factor in scenarios involving very high-resolution textures or large datasets
Who is this for?

This card is well-suited for users who run ray tracing and DLSS-enabled workloads, as both features are fully supported alongside DirectX 12 Ultimate and OpenGL 4.6. The combination of 35.48 TFLOPS of floating-point performance, 7168 shading units, and a boost clock of 2475 MHz makes it a solid fit for demanding rendering tasks at high resolutions. Users who need multi-display setups will also find it practical, with support for up to four simultaneous outputs across HDMI 2.1a and three DisplayPort connections. Additionally, the presence of ECC memory support makes it relevant for those running compute or content creation workloads where memory accuracy matters.

Who is this NOT for?

Users who require extensive VRAM for very high-resolution texture work or large-scale AI model inference may find the 12GB VRAM ceiling restrictive, as such workloads can quickly exhaust available memory. The 192-bit memory bus, while functional, may prove limiting for tasks that demand the highest possible memory bandwidth. Those who need USB-C display output will find no such port available on this card, which could be a drawback for users with USB-C or Thunderbolt-based monitors. Lastly, the absence of water-cooling support means users looking to build a custom liquid-cooled system will not be able to integrate this card into such a setup.
