MSI GeForce RTX 3090 VENTUS 3X 24G OC graphics card

24 GB GDDR6X for 8K workloads

The card delivers 24 GB of GDDR6X memory on a 384-bit bus for professional rendering and 8K content creation. It targets creators and enthusiasts who need maximum frame-buffer capacity. The PCI Express 4.0 x16 interface feeds data to the GeForce RTX 3090 GPU. Triple-fan thermal design sustains the factory overclock under load.

Memory capacity and bandwidth headroom

The 24 GB buffer handles massive texture sets, large scene files and multi-monitor 7680×4320 output without paging to system RAM. At 19500 MHz effective memory clock the 384-bit interface moves enough data for high-resolution ray-traced workloads. Extremely large datasets or multi-GPU scaling will eventually saturate the available VRAM and bus width.

PCI Express 4.0 x16 practical limits

The x16 link provides up to 32 GB/s bidirectional throughput for asset streaming and compute dispatch. Workloads that exceed this bandwidth will see reduced scaling when the GPU waits for host transfers. Platforms limited to PCI Express 3.0 halve the theoretical peak, which can become a bottleneck in sustained 8K production pipelines.
