ZOTAC AMP Extreme Holo GeForce RTX 3090

The ZOTAC AMP Extreme Holo GeForce RTX 3090 is a high-end graphics card built for enthusiasts and creators who need maximum GPU memory. It uses the NVIDIA Ampere architecture and delivers 10496 CUDA cores for demanding compute and rendering workloads. The card connects via PCI Express 4.0 and supports up to four displays.

24GB 384-Bit GDDR6X memory configuration

The 24GB GDDR6X frame buffer runs on a 384-bit bus at 19.5 Gbps, giving sustained bandwidth for long renders and large texture sets. A 420W thermal design power rating means the cooler must dissipate significant heat continuously. Three 8-pin power connectors and an 800W recommended PSU ensure stable current during extended sessions.

10496 CUDA cores and 24GB VRAM capacity

The combination of 10496 CUDA cores and 24GB GDDR6X memory is the specification that determines fit for 8K workflows, heavy 3D scenes and large-batch AI training. If your workload fits within that compute and memory envelope, this card matches the requirement.

Questions about this item

Will my case fit a triple-slot card with three fans?

The card uses a triple-fan cooler and a metal backplate, so it occupies three expansion slots. Measure your case clearance and check the slot spacing on your motherboard.

What power supply do I need for the 420 W board power?

ZOTAC recommends an 800 W PSU with three 8-pin PCIe connectors. Verify your unit has those cables before installing.

Can I drive a 7680 x 4320 display over the HDMI port?

The HDMI 2.1 port supports 7680 x 4320 resolution. Your monitor and cable must also support that mode.
