Gigabyte Aorus GeForce RTX 4080 Super Xtreme Ice

Manufacturer: Gigabyte

The Gigabyte Aorus GeForce RTX 4080 Super Xtreme Ice is a high-specification graphics card from Gigabyte's Aorus lineup, designed around Nvidia's Ada Lovelace architecture. It features 10,240 shading units and a boost clock of 2700 MHz, with support for ray tracing, DLSS, and DirectX 12 Ultimate. RGB lighting is built in, and the card accommodates up to four displays simultaneously.

On the memory side, the card carries 16GB of GDDR6X VRAM across a 256-bit bus, delivering a maximum bandwidth of 736.3 GB/s at an effective speed of 23,000 MHz. Floating-point performance is rated at 55.3 TFLOPS, while the texture rate reaches 864 GTexels/s across 320 texture mapping units. The card connects via PCIe 4.0, has a thermal design power of 320W, and is manufactured on a 5 nm process with approximately 45.9 billion transistors. Display outputs include one HDMI 2.1a port and three DisplayPort connectors, with Intel Resizable BAR support included.

Pros
  • Supports up to four simultaneous display outputs through a combination of one HDMI 2.1a port and three DisplayPort connectors
  • 16GB of GDDR6X VRAM with a 736.3 GB/s memory bandwidth suits workloads that require large frame buffers
  • Ray tracing and DLSS are both supported, expanding compatibility with modern rendering pipelines
  • ECC memory support adds data integrity for compute-oriented tasks
  • Built on a 5 nm process with 45,900 million transistors, reflecting a mature and dense silicon design
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can benefit certain workloads
Cons
  • A 320W TDP places substantial demands on system power delivery and cooling infrastructure
  • The card measures 357 mm in width, which may not fit in smaller or mid-tower chassis
  • No USB-C output is available, limiting connectivity options for certain monitors and devices
  • Air-water cooling is not supported, so thermal management relies entirely on the included air cooler
Who is this for?

This card is well-matched to users running demanding rendering and compute workloads that benefit from a large 16GB GDDR6X frame buffer and 736.3 GB/s of memory bandwidth. The combination of ray tracing support, DLSS, and DirectX 12 Ultimate makes it a strong fit for those working in modern real-time graphics pipelines, whether in content creation or graphically intensive applications. The four-display output capability — via HDMI 2.1a and three DisplayPort connectors — also suits users who require a multi-monitor setup for professional or productivity-driven environments. ECC memory support further extends its relevance to workloads where data accuracy is a priority.

Who is this NOT for?

Users working within compact or small-form-factor builds will likely find the 357 mm card length a practical obstacle, as it exceeds the clearance of many smaller chassis. The 320W TDP also makes this card a poor fit for systems with modest power supplies or limited airflow, since its thermal demands require a well-specced cooling and power infrastructure. Additionally, users who rely on USB-C monitor connectivity or require water-cooling integration will find the lack of USB-C outputs and the absence of air-water cooling support limiting for their specific setups.
