Manufacturer description

The Gigabyte GeForce RTX 4080 Super WINDFORCE V2 (GV-N408SWF3V2-16GD) is built on NVIDIA's Ada Lovelace architecture. It has 16GB of GDDR6X memory running at 23000MHz on a 256-bit bus and a 2550MHz core clock. That pairing is aimed at high-refresh 1440p and 4K gaming with ray tracing turned on. Fourth-generation Tensor Cores power DLSS 3.5. NVIDIA rates DLSS 3 at up to 4X the performance of brute-force rendering. Third-generation RT Cores deliver up to 2X ray tracing performance. If you also run local AI tools, the 16GB frame buffer and Tensor hardware give you room for quantized language…

SpecPicks Verdict

SpecPicks scored Gigabyte GeForce RTX 4080 Super WINDFORCE V2 Graphics Card using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the graphics cards category. GIGABYTE's graphics cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for graphics cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

What display outputs does the Gigabyte RTX 4080 Super WINDFORCE V2 have?

It has four outputs: three DisplayPort 1.4 ports and one HDMI 2.1a port. It does not have DisplayPort 2.1.

How much VRAM does this RTX 4080 Super have?

It has 16GB of GDDR6X memory running at 23000MHz on a 256-bit memory interface.

Will it work in my motherboard's PCIe slot?

The card uses a PCI-E 4.0 interface. PCI Express is backward and forward compatible, so it runs in a standard x16 slot on PCIe 3.0, 4.0 or 5.0 boards, at the link speed both sides support.

What power supply and case clearance do I need?

The product context doesn't list card length, slot width or a recommended PSU wattage. Check the product listing or Gigabyte's spec page for GV-N408SWF3V2-16GD before you buy.

Does this card support DLSS and ray tracing?

Yes. Fourth-generation Tensor Cores support NVIDIA DLSS 3.5, and third-generation RT Cores are rated for up to 2X ray tracing performance, according to the product listing.
