Gigabyte GeForce RTX 4080 Super Gaming

Manufacturer: Gigabyte

The Gigabyte GeForce RTX 4080 Super Gaming is a graphics card based on the Ada Lovelace architecture, produced on a 5 nm process node with 45,900 million transistors packed into the die. It runs at a base clock of 2295 MHz and boosts up to 2550 MHz under load, translating into 52.22 TFLOPS of floating-point throughput alongside a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixel/s.

The card is fitted with 16GB of GDDR6X VRAM on a 256-bit memory bus, reaching an effective memory speed of 23,000 MHz and a peak bandwidth of 736.3 GB/s. ECC memory is supported, and the feature set includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, and AMD SAM. Output connectivity spans one HDMI 2.1a port and three DisplayPort outputs, supporting up to four displays simultaneously. The card carries a TDP of 320W, connects via PCIe 4, measures 342 mm in length and 150 mm in height, and includes RGB lighting.

Pros
  • 16GB of GDDR6X VRAM on a 256-bit bus provides substantial memory capacity for texture-heavy and high-resolution workloads
  • A peak memory bandwidth of 736.3 GB/s supports fast data throughput across demanding rendering and compute tasks
  • Hardware ray tracing and DLSS are both supported, enabling accelerated lighting effects and upscaling without additional configuration
  • ECC memory support adds data integrity protection relevant to precision-sensitive compute use cases
  • Double Precision Floating Point is supported, broadening the card's applicability beyond graphics to numerical workloads
  • Four simultaneous display outputs via one HDMI 2.1a port and three DisplayPort connections offer flexible multi-monitor configurations
Cons
  • A TDP of 320W places considerable demands on both the power supply and system airflow
  • At 342 mm in length and 150 mm in height, the card requires a full-size case with ample clearance
  • Air-water hybrid cooling is not supported, leaving thermal management entirely dependent on the card's built-in air cooler
  • USB-C, DVI, and mini DisplayPort outputs are absent, limiting compatibility with certain display types
  • XeSS (XMX) is not supported, restricting upscaling options to DLSS only
Who is this for?

This card is a strong fit for users running high-resolution rendering and texture-intensive workloads, where the 16GB of GDDR6X memory and 736.3 GB/s of bandwidth provide meaningful headroom. The combination of hardware ray tracing, DLSS, and DirectX 12 Ultimate support makes it well-suited to those working with demanding real-time graphics pipelines. Users who need to connect up to four displays simultaneously — whether for creative work, simulation, or extended desktop setups — will find the output configuration practical. ECC memory and Double Precision Floating Point support also make it a reasonable choice for those with precision-sensitive compute workloads alongside their graphics tasks.

Who is this NOT for?

At 342 mm in length and 150 mm in height, the card is poorly matched to compact or small-form-factor builds where physical clearance is limited. Its 320W TDP makes it unsuitable for systems with modest power supplies or constrained airflow, as thermal and power demands are substantial. Users who rely on USB-C, DVI, or mini DisplayPort connections will find no native support for those interfaces, which creates a compatibility gap for certain monitor configurations. Additionally, those seeking an air-water hybrid cooling option will need to look elsewhere, as that feature is not available on this card.

General info:

GPU architecture Ada Lovelace
Thermal Design Power (TDP) 320W
PCI Express (PCIe) version 4
semiconductor size 5 nm
number of transistors 45900 million
Has air-water cooling ✕
width 342 mm
height 150 mm

Built on the Ada Lovelace architecture using a 5 nm process node, the card integrates 45,900 million transistors and connects to the system via PCIe 4. It carries a Thermal Design Power of 320W, which places a substantial demand on both the power supply and system cooling. Air-water hybrid cooling is not supported, so thermal management relies entirely on the card's own cooling solution. Physically, it measures 342 mm in width and 150 mm in height, making case compatibility an important consideration during installation.

Final Verdict

The Gigabyte GeForce RTX 4080 Super Gaming is a graphics card built around a dense Ada Lovelace die with 45,900 million transistors, and its specification sheet reflects that ambition — particularly in the memory department, where 16GB of GDDR6X with 736.3 GB/s of bandwidth gives it substantial throughput for demanding rendering, compute, and multi-display workloads. Ray tracing, DLSS, ECC support, and Double Precision Floating Point round out a capable feature set that extends its usefulness beyond conventional gaming. That said, its 320W TDP and considerable physical dimensions mean it rewards users who plan their system build accordingly. For those with the infrastructure to support it, the RTX 4080 Super Gaming delivers a well-equipped and technically comprehensive package.
