Gigabyte GeForce RTX 4080 Super Aero OC

Manufacturer: Gigabyte

The Gigabyte GeForce RTX 4080 Super Aero OC is a desktop graphics card built on NVIDIA's Ada Lovelace architecture, produced on a 5 nm process with 45,900 million transistors. It runs at a base clock of 2295 MHz and reaches a boost frequency of 2595 MHz, translating into 53.15 TFLOPS of floating-point output alongside a pixel rate of 290.6 GPixel/s and a texture rate of 830.4 GTexels/s.

The card is equipped with 16GB of GDDR6X memory on a 256-bit bus, achieving an effective speed of 23,000 MHz and a maximum bandwidth of 736.3 GB/s, with ECC memory support also included. It covers DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, and supports ray tracing, DLSS, stereoscopic 3D, and multi-display output across up to four screens via one HDMI 2.1a port and three DisplayPort connections. Intel Resizable BAR is supported, the card connects via PCIe 4, carries a 320W TDP, and measures 342 mm × 150 mm with air cooling and RGB lighting.

Pros
  • DLSS and ray tracing support are both present, broadening rendering options for compatible games and applications
  • ECC memory support adds data integrity protection relevant to compute-intensive or precision-sensitive workloads
  • The four-display output setup — combining one HDMI 2.1a port and three DisplayPort outputs — suits users running multi-monitor configurations
  • Intel Resizable BAR support enables the processor to access the full 16GB VRAM simultaneously, which can benefit frame delivery in supported scenarios
  • DPFP support extends the card's utility into workloads that require double precision computation
  • RGB lighting is integrated into the design, allowing visual customization without additional hardware
Cons
  • A 320W TDP places substantial demands on both the system power supply and case airflow management
  • The 342 mm length and 150 mm height make this a physically large card that requires careful case clearance planning
  • No USB-C output is available, which limits direct connection options for displays or devices that rely on that interface
  • Liquid or hybrid air-water cooling is absent, leaving thermal dissipation entirely to the air cooling solution
  • XeSS (XMX) is not supported, narrowing upscaling options to DLSS only
Who is this for?

This card is a solid match for users who regularly work across multi-display setups, given its four-output configuration with HDMI 2.1a and three DisplayPort connections. Its 53.15 TFLOPS of floating-point output, DPFP support, and ECC memory also make it relevant for those running GPU-accelerated compute workloads alongside gaming — tasks like 3D rendering or scientific computation that benefit from higher numerical precision and memory reliability. DLSS and ray tracing support further extend its appeal to users working within applications and game engines that leverage those rendering features.

Who is this NOT for?

Users building in compact or small-form-factor cases will likely find the 342 mm length and 150 mm height difficult to accommodate without careful planning, and the 320W TDP adds further constraints around power supply selection and case airflow. Those who depend on USB-C for monitor or device connectivity will find that option absent here entirely. Additionally, anyone looking for a card with integrated liquid or hybrid cooling will need to look elsewhere, as thermal management relies solely on the included air cooling solution.
