Gigabyte GeForce RTX 5080 Gaming OC

Name: Gigabyte GeForce RTX 5080 Gaming OC
Brand: Gigabyte
SKU: 9914

Manufacturer: Gigabyte

The Gigabyte GeForce RTX 5080 Gaming OC is a high-end graphics card based on NVIDIA's Blackwell architecture, fabricated on a 5 nm process and packed with 45,600 million transistors. It operates at a base clock of 2295 MHz with a boost frequency reaching 2730 MHz, and its 58.71 TFLOPS of floating-point performance reflects its position near the top of the current GPU stack. The card ships with RGB lighting and a 4-year warranty, and its thermal design power sits at 360W.

On the memory side, the RTX 5080 Gaming OC carries 16GB of GDDR7 VRAM across a 256-bit bus, delivering a maximum bandwidth of 960 GB/s at an effective speed of 30,000 MHz. The card features 10,752 shading units, 336 texture mapping units, and 112 render output units, translating to a texture rate of 917.3 GTexels/s and a pixel rate of 305.8 GPixels/s. It supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR, and connects to up to five displays via one HDMI 2.1b port and three DisplayPort outputs. The card interfaces with the system through a PCIe 5.0 slot and measures 340 mm in length and 140 mm in height.

Pros

Supports up to five simultaneous displays, offering flexibility for multi-monitor setups
Includes ray tracing and DLSS support, enabling advanced rendering features in compatible applications
ECC memory support adds a layer of data integrity for compute-oriented workloads
The 4-year warranty period is notably longer than many competitors in this category
GDDR7 memory delivers a maximum bandwidth of 960 GB/s across a 256-bit bus, enabling rapid data throughput
Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve utilization in compatible systems

Cons

A 360W TDP places significant demands on the power supply, requiring a well-specced system build
The card measures 340 mm in length, which may not fit in smaller or mid-tower chassis without clearance issues
Only one HDMI port is available, which could be limiting for users relying on multiple HDMI-connected displays
No USB-C output is present, restricting connectivity options for displays or devices that rely on that interface
Air-water hybrid cooling is not included, so thermal management depends entirely on the card's air cooling solution

Who is this for?

This card is well-suited to users running demanding graphics workloads that benefit from high floating-point throughput and fast memory bandwidth, such as 3D rendering, simulation, or content creation pipelines that leverage GPU compute. Its DLSS and ray tracing support make it a strong fit for those working with or playing titles that take advantage of these technologies, while ECC memory and Double Precision Floating Point support extend its relevance to users with compute-adjacent or professional workloads that require data accuracy. The five-display output capability also makes it a practical choice for users who need an expansive multi-monitor configuration in a single-card setup.

Who is this NOT for?

The card's 360W TDP and 340 mm length make it poorly suited to users working with compact or small-form-factor builds, where physical clearance and power delivery headroom are often limited. Those who rely heavily on HDMI connectivity for multiple displays may find the single HDMI port restrictive, particularly in setups that combine several HDMI-dependent devices. Additionally, users who need USB-C display output — whether for specific monitors, docking stations, or mixed-use peripherals — will find no such port available on this card, making it a poor match for workflows that depend on that interface.
