ZOTAC GeForce RTX 3090 Trinity OC 24GB GDDR6X graphics card ZT-A30900J-10P

ZOTAC GeForce RTX 3090 Trinity OC 24GB

The ZOTAC GeForce RTX 3090 Trinity OC is a graphics card built on the NVIDIA Ampere architecture with 10496 CUDA cores and a 1710 MHz boost clock. It carries 24GB of GDDR6X memory across a 384-bit interface running at 19.5 Gbps. The card connects via PCI Express 4.0 and fits systems with a 750W power supply and dual 8-pin connectors. It targets creators and enthusiasts who need maximum frame-buffer capacity.

24GB GDDR6X upgrade path

Moving to this 24GB model from a 10GB or 12GB card removes the memory ceiling that forces texture streaming compromises at 4K and 8K. The 384-bit bus and 19.5 Gbps data rate deliver bandwidth that smaller buses cannot match. The jump is worth it when workloads exceed 10GB of VRAM, such as large-scene rendering, high-resolution video timelines, or multi-monitor gaming at 7680 x 4320. The 350W TDP demands a robust power supply and case airflow.

24GB capacity and headroom

The 24GB frame buffer comfortably holds 8K textures, deep learning datasets, and complex 3D scenes without swapping to system memory. Four display outputs — one HDMI 2.1 and three DisplayPort 1.4a — drive multi-monitor arrays at 7680 x 4320. Headroom runs out when compute throughput becomes the bottleneck before memory fills, such as in shader-heavy titles at extreme frame rates or single-GPU training jobs that exceed the 10496 CUDA core count. IceStorm 2.0 cooling and SPECTRA 2.0 RGB lighting complete the package.
