Gigabyte GeForce RTX 4080 Super WindForce specifications and in-depth review

Gigabyte GeForce RTX 4080 Super WindForce

Manufacturer: Gigabyte

The Gigabyte GeForce RTX 4080 Super WindForce is a desktop graphics card built on NVIDIA's Ada Lovelace architecture, fabricated on a 5 nm process with 45,900 million transistors. It runs at a base clock of 2295 MHz and boosts up to 2550 MHz, delivering 52.22 TFLOPS of floating-point performance alongside a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixel/s.

The card carries 16GB of GDDR6X memory on a 256-bit bus, operating at an effective speed of 23,000 MHz with a maximum bandwidth of 736.3 GB/s, and includes ECC memory support. It covers DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, with ray tracing, DLSS, stereoscopic 3D, and multi-display support for up to four screens via one HDMI 2.1a port and three DisplayPort outputs. The card connects via PCIe 4, has a rated TDP of 320W, supports Intel Resizable BAR, features RGB lighting, and measures 330 mm × 136 mm with air cooling only.

Pros
  • Ray tracing and DLSS support are both included, expanding rendering options within compatible applications and game engines
  • 16GB of GDDR6X memory running at 736.3 GB/s of bandwidth provides substantial throughput for memory-intensive workloads
  • ECC memory support is present, adding data integrity protection useful in compute-sensitive tasks
  • Four-display output via one HDMI 2.1a port and three DisplayPort connections suits users running multi-monitor setups
  • Intel Resizable BAR support allows the processor to access the full VRAM pool simultaneously, benefiting supported workloads
  • DPFP support extends compute applicability to tasks requiring double precision numerical accuracy
Cons
  • A 320W TDP places considerable demands on the system power supply and requires adequate case airflow
  • At 330 mm in length, the card needs a full-size case with sufficient internal clearance
  • No USB-C output is available, which limits direct connectivity for displays or devices that depend on that interface
  • Liquid or hybrid air-water cooling is absent, with thermal management relying solely on the air cooling solution
  • XeSS (XMX) is not supported, restricting upscaling to DLSS only
Who is this for?

The Gigabyte GeForce RTX 4080 Super WindForce suits users who need a card capable of handling both gaming and GPU-accelerated compute workloads, given its DPFP support, ECC memory, and 52.22 TFLOPS of floating-point output. Those running multi-display configurations will appreciate the four-output setup across one HDMI 2.1a port and three DisplayPort connections. DLSS and ray tracing support also make it a practical fit for users working in applications and engines that take advantage of those rendering capabilities.

Who is this NOT for?

Users planning a compact or small-form-factor build will likely struggle with the 330 mm card length and the system-level demands of a 320W TDP, both of which require a well-spaced case and a suitably rated power supply. Anyone who relies on USB-C for display or device connectivity will find that option entirely absent on this card. Those seeking a card with integrated liquid or hybrid cooling should also look elsewhere, as thermal management here is limited to the air cooling solution alone.

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 330 mm
height 136 mm

The card is based on the Ada Lovelace architecture, produced on a 5 nm process with 45,900 million transistors, and uses a PCIe 4 interface. Its TDP is rated at 320W, and cooling is handled entirely through air, as liquid or hybrid air-water cooling is not supported. The physical footprint comes in at 330 mm wide and 136 mm tall, which should be factored in when assessing case compatibility.

Final Verdict

The Gigabyte GeForce RTX 4080 Super WindForce is a well-rounded Ada Lovelace-based graphics card that covers a useful range of both gaming and compute-oriented workloads, backed by DPFP support, ECC memory, and a four-display output configuration. Its 16GB of GDDR6X memory running at 736.3 GB/s of bandwidth gives it genuine headroom for memory-intensive tasks, while ray tracing and DLSS support extend its relevance across a range of rendering scenarios. Prospective buyers should be mindful of the 320W TDP, 330 mm card length, and air-only cooling when planning a build around it. For users with a compatible system and a need for versatile graphics and compute performance, the WindForce represents a capable and feature-complete option within this category.
