24 GB GDDR6X frame buffer

This MSI GeForce RTX 4090 Gaming X Trio 24G graphics card equips 24 GB of GDDR6X memory on a 384‑Bit interface. The 16384 CUDA cores and PCI Express 4.0 link deliver high throughput for 4K and 8K workloads. It targets enthusiasts who need maximum VRAM for rendering, simulation or high‑refresh gaming.

450 W TDP with single 16‑Pin connector

The board draws up to 450 W and is fed through one 16‑Pin power connector. A power supply that can sustain this load with the required cable is the deciding factor for compatibility. Builders must verify their PSU rating and cable layout before purchase.

Suits 4K creators and high‑refresh gamers

The HDMI 2.1 port and three DisplayPort 1.4a outputs drive up to four displays at 7680 x 4320 resolution. The 337 mm length demands a spacious chassis with adequate airflow. Users with smaller cases or lower‑wattage supplies should consider a more compact model.

Questions about this item

What does 16384 CUDA cores mean for real-world 4K gaming?

The 16384 CUDA cores handle massive parallel workloads, enabling high frame rates at 7680 x 4320 resolution in supported titles.

How does PCI Express 4.0 affect bandwidth with this card?

PCI Express 4.0 provides the link between GPU and motherboard; the 384-bit GDDR6X memory interface determines the card's internal bandwidth ceiling.

Will the 337 mm length fit in a standard mid-tower case?

At 337 mm long the card needs a case with at least that much clear GPU clearance; measure from the rear bracket to the nearest drive cage or fan.
