Asus ProArt GeForce RTX 4080 Super OC Edition specifications and in-depth review

Asus ProArt GeForce RTX 4080 Super OC Edition

Manufacturer: Asus

The Asus ProArt GeForce RTX 4080 Super OC Edition is a graphics card from Asus designed around Nvidia's Ada Lovelace architecture, fabricated on a 5 nm process node with 45,900 million transistors. It runs at a base clock of 2295 MHz and reaches a boost clock of 2610 MHz under load, with support for ray tracing, DLSS, DirectX 12 Ultimate, stereoscopic 3D, and RGB lighting. Up to four displays can be driven simultaneously through its four available output ports.

The card is equipped with 16GB of GDDR6X VRAM on a 256-bit memory bus running at an effective speed of 23,000 MHz, providing a peak bandwidth of 736.3 GB/s. ECC memory support and Intel Resizable BAR are both present. With 10,240 shading units, 320 texture mapping units, and 112 render output units, it delivers a texture rate of 835.2 GTexels/s and 53.45 TFLOPS of floating-point throughput. The output configuration consists of one HDMI 2.1a port and three DisplayPort outputs, with no USB-C, DVI, or mini DisplayPort connections available. The card has a 320W TDP, connects via PCIe 4.0, and measures 300 mm in width and 120 mm in height, with air cooling only.

Pros
  • 16GB of GDDR6X VRAM on a 256-bit bus supports memory-intensive rendering and compute workloads
  • A peak memory bandwidth of 736.3 GB/s enables sustained high-speed data throughput for demanding tasks
  • ECC memory support provides data integrity assurance for reliability-sensitive workloads
  • Ray tracing and DLSS are both supported alongside DirectX 12 Ultimate, covering advanced rendering use cases
  • At 300 mm wide and 120 mm tall, the card occupies a more compact footprint than many other cards at this specification tier
  • Intel Resizable BAR support is included, allowing broader CPU access to the full VRAM pool
Cons
  • A 320W TDP places significant power demands on the host system, requiring adequate power supply headroom
  • Water cooling is not supported, restricting thermal management entirely to the built-in air cooling solution
  • No USB-C output is available, limiting display compatibility for users with USB-C or Thunderbolt-based monitors
  • XeSS (XMX) is not supported, leaving DLSS as the only hardware-accelerated upscaling option
  • Only one HDMI port is provided, which may be restrictive for users who rely primarily on HDMI connections
Who is this for?

The Asus ProArt GeForce RTX 4080 Super OC Edition is a strong fit for users engaged in compute and content creation workloads that benefit from a large VRAM pool, high memory bandwidth, and ECC memory support — all of which are present on this card. Its 53.45 TFLOPS of floating-point throughput and 10,240 shading units make it well-suited for rendering-intensive tasks that can take advantage of ray tracing, DLSS, and DirectX 12 Ultimate. The card's relatively compact dimensions of 300 mm by 120 mm also make it a practical option for users who need high-tier GPU specifications in a more space-conscious build than larger cards in this class typically allow.

Who is this NOT for?

Users building in cases with strict power constraints may find the 320W TDP a limiting factor, as it demands a well-rated power supply and sufficient system cooling to operate reliably. Those who require water-cooling integration will not find support for it here, as the card is limited to air cooling only. Users who depend on USB-C display output will also be underserved, since no such port is present, and those needing more than one HDMI connection will find only a single HDMI 2.1a port available on this card.
