16GB GDDR6X frame buffer

The GIGABYTE GeForce RTX 4080 SUPER WINDFORCE V2 is a graphics card built on the Ada Lovelace architecture for 4K gaming and content creation. It delivers 10240 CUDA cores and a 2550 MHz core clock through a PCI Express 4.0 interface. The 16GB GDDR6X memory runs at 23 Gbps across a 256-bit bus. It suits enthusiasts who need high throughput for rendering and ray-traced titles.

Upgrade from 12GB 4080-class cards

Moving to this model adds 4GB of VRAM and a faster effective memory clock, which helps with large texture packs and heavy compute workloads. The jump is worth it when 12GB buffers become a bottleneck at 4K or in professional applications. The Ada Lovelace architecture also brings improved efficiency over prior generations. Dual BIOS lets you choose between performance and quieter operation without flashing firmware.

ATX build with 750W PSU and 16-pin power

The card measures 330 mm long and occupies 3 slots, so verify case clearance before installing. It draws up to 320W and requires a single 16-pin connector from a 750W or larger power supply. Outputs include one HDMI 2.1a and three DisplayPort 1.4a ports for up to four displays at 7680 x 4320 resolution. A metal backplate adds structural rigidity and helps dissipate heat from the PCB.

Questions about this item

Will the 330 mm length and 3-slot width fit my ATX case?

The card measures 330 mm long and occupies 3 expansion slots, so verify your case supports at least that length and slot count before purchase.

Which power connector does the 320 W board need and what PSU is recommended?

It requires one 16-pin connector and a 750 W power supply; connect the 16-pin directly from the PSU without adapters to avoid melted pins.

How do I clean the triple WINDFORCE fans and replace thermal pads later?

Remove the three fans by unscrewing the fan shroud, blow dust from the heatsink fins, and reapply thermal pads on the GPU die and memory modules when temperatures rise.
