GIGABYTE GeForce RTX 3090 GAMING OC 24GB graphics card GVN3090GAMINGOC24GD

24GB GDDR6X for creators and AI

The GIGABYTE GeForce RTX 3090 GAMING OC delivers 24GB of GDDR6X memory across a 384-bit interface. 10496 CUDA cores and a 1755 MHz core clock handle 3D rendering, large dataset training and high-resolution video editing. The card drives up to four displays via two HDMI 2.1 and three DisplayPort 1.4a outputs at 7680 x 4320 resolution.

Upgrade from 10GB or 12GB VRAM cards

Moving from a 10GB or 12GB model removes the memory ceiling that forces texture downgrades or out-of-memory crashes in heavy scenes. The 24GB buffer lets you keep full-resolution assets resident and train larger batches without offloading to system RAM. The jump is worth it when your current card hits its VRAM limit before its compute limit.

Fits ATX builds with 750W PSU and 320 mm clearance

The 320 mm ATX form factor requires a case with matching GPU length clearance. A 750W power supply feeds the 350W TDP through two 8-pin connectors. PCI Express 4.0 interface connects to modern platforms, while the WINDFORCE 3X cooler and metal backplate manage thermals in multi-GPU NVLINK configurations.
