GeForce RTX 4080 SUPER 16GB

The GIGABYTE GeForce RTX 4080 SUPER WINDFORCE V2 16G is a PCI Express 4.0 graphics card built on the Ada Lovelace architecture. It delivers 10240 CUDA cores with a 2550 MHz core clock and 16GB of GDDR6X memory across a 256-bit interface running at 23 Gbps. The card targets 4K gaming and content creation workloads that benefit from DLSS 3 and hardware ray tracing.

WINDFORCE cooling with metal back plate

Three WINDFORCE fans drive airflow through a heatsink assembly while a protection metal back plate adds structural rigidity and helps prevent PCB flex. A Dual BIOS switch lets you select between performance and quiet profiles without software. The I/O bracket provides one HDMI 2.1a port and three DisplayPort 1.4a connectors for up to four simultaneous displays at 7680 x 4320 resolution. An anti-sag bracket is included to support the card's weight in the slot.

Upgrade from 12GB 4080-class cards

Moving from a 12GB 4080-class GPU adds 4GB of frame buffer and higher memory bandwidth, which matters for 4K texture packs, large 3D scenes and multi-monitor setups. The Ada Lovelace core also brings 4th Generation Tensor Cores and 3rd Generation RT Cores, enabling DLSS 3 frame generation and improved ray tracing throughput. The jump is worth it when your current 12GB card hits memory limits or you need the extra encoder headroom for streaming at high resolution.

Questions sur cet article

What bandwidth does the PCI Express 4.0 interface cap at in practice?

The PCI Express 4.0 link delivers up to 16 GT/s per lane, so a full x16 slot provides roughly 32 GB/s of usable bandwidth for the GV-N408SWF3V2-16GD.

What case clearance and power connectors does the card need to fit?

The triple-fan WINDFORCE cooler makes this a 3-slot design; allow at least 40 mm of clearance above the motherboard and ensure your PSU has a 12VHPWR or three 8-pin PCIe connectors.

How is the card installed, and which step do builders most often miss?

Seat the card in the top PCIe 4.0 x16 slot, secure the rear bracket screws, attach the anti-sag bracket to the case, then connect all required 12VHPWR or 8-pin power leads before closing the chassis.
