GIGABYTE GV-N4090GAMING OC-24GD GeForce RTX 4090 graphics card

Built for 24GB workloads

This GIGABYTE Gaming GeForce RTX 4090 delivers 16384 CUDA cores and 24GB of GDDR6X memory on a 384-bit bus. It targets creators and engineers who need maximum VRAM for large models, high-resolution rendering or complex simulations. The triple-fan cooler handles the 450W TDP under sustained load.

Suits 4K creators and AI developers.

The card fits builders running 1000W or larger power supplies with a 16-pin connector and 340mm case clearance. It supports four displays via HDMI 2.1 and three DisplayPort 1.4 outputs at up to 7680x4320 resolution. Systems with smaller PSUs, tight cases or lower-resolution targets should consider smaller GPUs.

24GB GDDR6X decides fit for memory-bound tasks

The 24GB frame buffer is the single spec that determines whether this model matches the workload. Applications that exceed 16GB or 20GB VRAM on lesser cards will run without paging here. If the project fits in less memory, a lower-capacity GPU saves power and cost.
