Name: Gigabyte GeForce RTX 5080 WindForce SFF
Brand: Gigabyte
SKU: 2857

Manufacturer: Gigabyte

The Gigabyte GeForce RTX 5080 WindForce SFF is a graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5nm process and equipped with 10,752 shading units. Designed for high-end desktop use, it operates at a base clock of 2,295 MHz with a boost reaching 2,617 MHz, and its 56.28 TFLOPS of floating-point performance reflects the computational headroom the GPU offers. The card carries a 360W thermal design power rating and measures 304mm in length and 126mm in height, making its physical footprint a relevant consideration for case compatibility.

On the memory side, the RTX 5080 WindForce SFF is outfitted with 16GB of GDDR7 VRAM running across a 256-bit bus at an effective speed of 30,000 MHz, yielding a maximum bandwidth of 960 GB/s. It supports ECC memory and delivers a texture rate of 879.3 GTexels/s alongside a pixel rate of 293.1 GPixels/s, backed by 336 TMUs and 112 ROPs. Display connectivity includes one HDMI 2.1b port and three DisplayPort outputs, supporting up to four simultaneous displays. The card is compatible with DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3.0, and includes support for ray tracing and DLSS, while also featuring Intel Resizable BAR. Gigabyte backs the card with a four-year warranty.

Pros

Supports up to four simultaneous displays through a combination of three DisplayPort outputs and one HDMI 2.1b port
16GB of GDDR7 VRAM paired with a 256-bit bus delivers 960 GB/s of memory bandwidth, which is substantial for memory-intensive workloads
ECC memory support adds data integrity for compute-oriented tasks
Includes ray tracing and DLSS support, expanding compatibility with modern rendering techniques
Backed by a four-year warranty, which is longer than many graphics cards in this category
Intel Resizable BAR support allows the CPU to access the full VRAM pool, which can benefit GPU-bound workloads

Cons

360W TDP places significant power demands on the system, requiring a capable PSU and good case airflow
No USB-C output is available, limiting compatibility with certain modern displays and devices
The card does not include water cooling, relying entirely on air cooling to manage its 360W thermal load
At 304mm in length, physical fitment may be a concern in compact or mid-tower cases
RGB lighting is absent, which may matter to users building visually themed systems

Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, given its 56.28 TFLOPS of floating-point performance, DPFP support, and ECC memory — all of which benefit tasks like 3D rendering, simulation, and GPU-accelerated computing. Enthusiast desktop builders who need multi-display setups will find the four-output configuration practical, while those working with large assets or high-resolution textures will appreciate the 16GB of GDDR7 VRAM and 960 GB/s of memory bandwidth. The inclusion of ray tracing and DLSS also makes it a fitting choice for users engaged in modern real-time graphics workloads.

Who is this NOT for?

Users with compact or small-form-factor builds may find the 304mm length and 360W TDP difficult to accommodate, as both place real demands on case space and power delivery. The absence of a USB-C output makes it a poor fit for anyone relying on USB-C-compatible displays or accessories. Additionally, users who prioritize a visually themed system will find the lack of RGB lighting a limitation, and those seeking a passively or water-cooled solution will need to look elsewhere, as this card relies solely on air cooling to manage its considerable thermal output.
