Asus TUF Gaming GeForce RTX 5080 OC Edition

Name: Asus TUF Gaming GeForce RTX 5080 OC Edition
Brand: Asus
SKU: 66067

Manufacturer: Asus

The Asus TUF Gaming GeForce RTX 5080 OC Edition is a high-end graphics card from Asus that sits within the current Blackwell generation of NVIDIA hardware. Designed with enthusiast-level workloads in mind, it carries a 2700 MHz GPU turbo clock and a base clock of 2295 MHz, reflecting the OC Edition tuning applied at the factory. The card measures 348 mm in length and 146 mm in height, and it includes RGB lighting alongside a traditional air-cooling solution.

On the memory side, the card is equipped with 16GB of GDDR7 VRAM running across a 256-bit bus at an effective speed of 30000 MHz, delivering up to 960 GB/s of memory bandwidth. It carries 10752 shading units, 336 texture mapping units, and 112 render output units, contributing to a texture rate of 907.2 GTexels/s and a floating-point throughput of 58.06 TFLOPS. The card supports ray tracing, DLSS, DirectX 12 Ultimate, OpenGL 4.6, and Intel Resizable BAR, while connectivity is handled through two HDMI 2.1b ports and three DisplayPort outputs, supporting up to four displays simultaneously. Its rated TDP stands at 360W over a PCIe 5 interface, and the GPU is built on a 5 nm process containing approximately 45.6 billion transistors.

Pros

Supports up to four simultaneous displays, making it well-suited for multi-monitor setups
Five video outputs in total, combining two HDMI 2.1b ports and three DisplayPort connections, offers flexible display configuration
ECC memory support adds a layer of data reliability for compute-intensive tasks
DLSS and ray tracing support are both present, covering two of the more demanding modern rendering features
Double Precision Floating Point (DPFP) support extends the card's usability beyond gaming into compute workloads
Intel Resizable BAR support allows the CPU to access the full VRAM pool, which can improve frame delivery in supported scenarios

Cons

A 360W TDP places significant demand on the power supply and system cooling infrastructure
The card measures 348 mm in length, which may not fit in smaller or mid-tower cases without careful planning
No USB-C output is available, limiting direct connectivity to USB-C monitors or displays without an adapter
Air-water hybrid cooling is not included, so users seeking liquid cooling would need to source a third-party solution
The 256-bit memory bus width is narrower than what some other high-end cards in this tier offer, though this is partially offset by GDDR7 speeds

Who is this for?

This card is a strong fit for users running demanding rendering and compute workloads, given its 58.06 TFLOPS of floating-point throughput, DPFP support, and ECC memory capability. Those working with ray-traced visuals or relying on DLSS for real-time rendering acceleration will find the feature set directly relevant to their needs. The five-output configuration and support for up to four simultaneous displays also make it well-suited for multi-monitor productivity or simulation environments where screen real estate is a priority.

Who is this NOT for?

Users working within tight spatial constraints will find the 348 mm card length a genuine obstacle, as it rules out many compact and standard mid-tower enclosures without careful case selection. The 360W TDP also makes this card a poor fit for anyone operating a system with a modest power supply or limited chassis airflow, since the thermal and electrical demands are considerable. Additionally, those needing USB-C display output will be unable to connect compatible monitors directly, as no such port is present on this card.
