ASUS PRIME-RTX5080-O16G-EVO GeForce RTX 5080 graphics card

SKU CH-ZPMB-8SJ64 MPN PRIME-RTX5080-O16G-EVO

GeForce RTX 5080 GPU with 16 GB GDDR7 memory, 10752 CUDA cores and a 2685 MHz OC boost clock on a PCI Express 5.0 interface

  • Graphics processorGeForce RTX 5080
  • Memory capacity16 GB
  • Interface typePCI Express 5.0
  • CUDA core count10752
  • Highest resolution7680 × 4320
  • Boost frequencyOC mode: 2685 MHz Default mode: 2655 MHz (Boost Clock)

Edition PRIME OC EVO

  • 16 GB GDDR7 memory delivers 30 Gbps bandwidth for high-resolution textures
  • 10752 CUDA cores accelerate compute-heavy workloads and ray tracing
  • OC boost clock reaches 2685 MHz for extra gaming headroom
  • PCI Express 5.0 interface doubles link bandwidth versus older standards
  • HDMI 2.1b plus three DisplayPort 2.1b outputs drive four 8K displays

16GB GDDR7 graphics card

The ASUS PRIME GeForce RTX 5080 delivers 16GB of GDDR7 memory on a 256-bit interface for high-resolution gaming and content creation. It connects via PCI Express 5.0 and provides one HDMI 2.1b and three DisplayPort 2.1b outputs to drive up to four displays at 7680 x 4320. The card occupies 2.5 slots and measures 304 mm in length.

Sustained load behaviour

Under continuous load the GPU runs at a default boost clock of 2655 MHz and can reach 2685 MHz in OC mode across 10752 CUDA cores. The triple-fan cooler is designed to maintain these frequencies during extended sessions while drawing power through a single 16-pin connector from an 850W supply. Memory operates at an effective 30000 MHz to keep bandwidth stable.

PCI Express 5.0 and display limits

The PCI Express 5.0 link supplies the full bandwidth available to the RTX 5080 without bottlenecking the 30 Gbps memory subsystem. DisplayPort 2.1b and HDMI 2.1b ports support the card's maximum 7680 x 4320 resolution across four monitors. DLSS 4.0 and OpenGL 4.6 provide the software path for AI-accelerated rendering at that resolution.

Questions about this item

How loud and hot does the triple-fan cooler get when the RTX 5080 runs at its 2685 MHz OC boost clock all day?

The card uses a triple-fan design within a 2.5-slot ATX form factor to manage heat from the 10752 CUDA cores and 16GB GDDR7 memory under sustained load.

My power supply only has 8-pin cables — what exactly must I already own to feed the single 16-pin connector on this RTX 5080?

An 850 W PSU with a native 12VHPWR 16-pin output or the supplied 1-to-3 adapter cable that converts three 8-pin PCIe plugs into the required 16-pin connector.

Will the PCI Express 5.0 x16 interface on this RTX 5080 work properly in my older motherboard that only has a PCIe 4.0 slot?

Yes, the PCIe 5.0 interface is backward compatible with PCIe 4.0 and 3.0 slots, so the card will function at the motherboard's maximum supported speed.
