Manufacturer description

The ZOTAC Gaming GeForce RTX 3090 Trinity OC pairs NVIDIA's Ampere architecture with 24GB of GDDR6X memory on a 384-bit bus running at 19.5 Gbps. That much VRAM lets you run 4K textures, heavy mods and large local AI models that would overflow a smaller card's memory. The card boosts to 1710 MHz and adds 2nd Gen Ray Tracing Cores and 3rd Gen Tensor Cores for ray-traced lighting and DLSS upscaling. It supports DirectX 12 Ultimate, Vulkan RT and OpenGL 4.6. For displays, you get 3 x DisplayPort 1.4a and 1 x HDMI 2.1. The card can drive four screens at once and output up to 7680x4320, and it…

SpecPicks Verdict

SpecPicks scored ZOTAC Gaming GeForce RTX™ 3090 Trinity OC 24GB GDDR6X 384-bit 19.5… using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the graphics cards category. ZOTAC's graphics cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for graphics cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Is 24GB of VRAM on the RTX 3090 Trinity OC enough for running local AI models?

The card has 24GB of GDDR6X on a 384-bit bus plus 3rd Gen Tensor Cores. That is enough to hold many quantized large language models and image-generation models fully in VRAM. The largest models still need more memory or several GPUs.

What power supply do I need for the ZOTAC RTX 3090 Trinity OC?

ZOTAC rates the card at 350W and recommends a 750W power supply. If you're pairing it with a high-draw CPU, leave yourself extra headroom above that.

Will this card fit in my case?

The card is 2.5 slots thick, so it covers more than two expansion slots. Exact length and height aren't given here, so check the product listing for dimensions and compare them with your case's GPU clearance.

How many monitors can I connect, and does it support 8K?

Yes. It has 3 x DisplayPort 1.4a and 1 x HDMI 2.1, runs up to four displays at once, and supports a maximum digital resolution of 7680x4320 (8K).

Are the fans loud when I'm just browsing or idling?

The IceStorm 2.0 cooler has FREEZE Fan Stop, which stops the fans at light loads, and Active Fan Control adjusts fan speed as temperatures rise under gaming or compute loads.

Which local LLMs fit in 24 GB?

24 GB holds a 30–35B model at Q4 entirely in VRAM — the step where 27B-class models stop spilling to system RAM.

✅ 7–9B models (Llama 3.1 8B, Qwen 3 8B) — fits at Q4
✅ 12–14B models (Qwen 3 14B, Phi-4) — fits at Q4
✅ 20–27B models (Gemma 3 27B, Mistral Small) — fits at Q4
✅ 30–35B models (Qwen 3 32B, QwQ 32B) — fits at Q4
❌ 70B models (Llama 3.3 70B, Qwen 2.5 72B) — needs 48 GB+

Across 7 community runs from 5 sources, the NVIDIA GeForce RTX 3090 generates a median 95.7 tok/s on 7–9B models at Q4 (per LocalScore (Mozilla Builders)).
