TUF Gaming RTX 5080 16GB GDDR7

The ASUS TUF Gaming GeForce RTX 5080 is a graphics card built on the Blackwell architecture with 10752 CUDA cores. It delivers 16GB of GDDR7 memory across a 256-Bit interface for 960 GB/sec bandwidth. The PCI Express 5.0 interface connects to modern platforms. It targets enthusiasts seeking high frame rates at 4K resolution.

Upgrade from prior 16GB cards

Moving from an older 16GB GPU brings the Blackwell architecture and GDDR7 memory bandwidth. The jump is worth it when your workload needs the 960 GB/sec throughput or the updated feature set including DLSS 4.0. The 360W thermal design power requires adequate cooling and power supply headroom. The 348mm length must fit your chassis.

PCI Express 5.0 interface limits

The card uses a PCI Express 5.0 x16 slot for full bandwidth. On a PCI Express 4.0 platform the link negotiates to 4.0 speeds, which may cap peak throughput in bandwidth-heavy scenarios. The 256-Bit memory bus and 16GB capacity define the frame buffer ceiling for 7680 x 4320 output across up to four displays.

Questions about this item

What case clearance does the 348 mm card length and 72 mm thickness require?

The card measures 348 mm long and 72 mm thick, so your case must provide at least that much GPU clearance and a three-slot bracket opening.

Which PCIe power connectors does the 360 W TDP demand?

The 360 W thermal design power requires three 8-pin PCIe power connectors from the PSU; omitting one connector is the common install mistake.

How often should the three axial fans and heatsink fins be cleaned?

Dust the three axial fans and heatsink fins every three to six months with compressed air to maintain the 360 W cooling headroom.
