It delivers 57.09 TFLOPS of floating-point performance alongside a texture rate of 892.1 GTexels/s, backed by 336 TMUs and 112 ROPs. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, Intel Resizable BAR, and ECC memory, while connectivity is handled through one HDMI 2.1b port and three DisplayPort outputs.

Pros

Supports up to four simultaneous display outputs, offering flexible multi-monitor configurations
16GB of GDDR7 VRAM with a 960 GB/s memory bandwidth suits demanding rendering and compute workloads
Ray tracing and DLSS support are both present, expanding compatibility with modern rendering pipelines
ECC memory support adds data integrity for workloads sensitive to memory errors
Intel Resizable BAR is included, allowing the CPU broader access to GPU frame buffer data
The 256-bit memory bus paired with a 30,000 MHz effective memory speed results in substantial data throughput

Cons

A 360W TDP places significant power demands on the system, requiring a capable power supply
No USB-C display output is available, limiting connectivity options for certain modern monitors
Air-water cooling is not supported, restricting cooling flexibility to air-only solutions
The card does not include RGB lighting, which may matter to users building visually coordinated systems
No DVI or mini DisplayPort outputs are present, excluding compatibility with older display interfaces

Who is this for?

This card is well-suited to users running demanding rendering, compute, or simulation workloads that benefit from high memory bandwidth and ECC support, such as 3D artists, visual effects professionals, and technical computing users. The combination of ray tracing support, DLSS, and a high shading unit count also makes it a strong fit for high-resolution gaming at demanding quality settings. Users who need to drive up to four displays simultaneously will find the multi-output configuration practical for expansive desktop setups or professional monitoring environments.

Who is this NOT for?

The card's 360W TDP makes it a poor fit for users with modest or older power supplies, as the system demands around it are substantial and non-negotiable. Those working in compact or small-form-factor builds will also find the 304 mm length and air-only cooling requirement limiting, as the card offers no air-water cooling flexibility. Additionally, users who rely on USB-C display connectivity or legacy interfaces like DVI will face compatibility gaps, since none of those outputs are available on this model.

Final Verdict

The Asus Prime GeForce RTX 5080 OC Edition is a technically dense graphics card built around NVIDIA's Blackwell architecture, and its specification sheet reflects that clearly. With 960 GB/s of memory bandwidth delivered through 16GB of GDDR7 across a 256-bit bus, alongside ray tracing, DLSS, ECC memory support, and a 2655 MHz boost clock, it is equipped for both graphically intensive workloads and professional compute tasks. The 360W TDP and air-only cooling requirement mean it demands careful system planning, and the absence of USB-C display output is a practical limitation worth noting. For users whose workloads and system configurations align with what this card requires, it represents a well-specified option within the high-end discrete graphics card segment.
