Manufacturer description
The ASUS TUF Gaming GeForce RTX 3080 Ti OC Edition pairs NVIDIA's Ampere architecture with 12GB of GDDR6X memory running at 19 Gbps. It suits high-refresh 1440p and 4K gaming, plus GPU compute work that fits within 12GB. Ampere Streaming Multiprocessors deliver 2X the FP32 throughput of the previous generation. 2nd-gen RT Cores double ray-tracing throughput and run ray tracing and shading at the same time. 3rd-gen Tensor Cores power DLSS, which lifts frame rates at high resolutions. The card has HDMI 2.1 and DisplayPort 1.4a outputs and a maximum digital resolution of 7680 x 4320, so it can…
SpecPicks Verdict
SpecPicks scored ASUS TUF Gaming NVIDIA GeForce RTX 3080 Ti OC Edition Graphics Card using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the graphics cards category.

Frequently Asked Questions
How much VRAM does the ASUS TUF RTX 3080 Ti OC have?
It has 12GB of GDDR6X memory rated at 19 Gbps. That is enough for 1440p and most 4K gaming, but it caps how large a local AI model or dataset fits on the card.
What warranty comes with this card?
The listing states a 3-year warranty. Check ASUS's warranty page for registration requirements and the coverage terms in your region.
Can it drive an 8K or 4K 120Hz display?
Yes. The card has HDMI 2.1 and DisplayPort 1.4a outputs and supports a maximum digital resolution of 7680 x 4320. HDMI 2.1 is the port to use for 4K high-refresh TVs.
Will it work in a PCIe 3.0 motherboard?
The card uses a PCIe 4.0 interface, and PCIe is backward compatible, so it runs in a PCIe 3.0 x16 slot at that slot's bandwidth. Also confirm your power supply and case clearance against ASUS's published specs.
What software controls overclocking and fan speeds?
ASUS GPU Tweak II handles performance tuning, thermal and fan controls, and system monitoring. ASUS advises against using unofficial tuning software with this card.

Which local LLMs fit in 12 GB?
12 GB holds models up to about 14B at Q4 with a usable context window; above that band the weights spill to system RAM and system-RAM bandwidth sets the speed, not the GPU.
- ✅ 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) — needs 20 GB+
- ❌ 30–35B models (Qwen 3 32B, QwQ 32B) — needs 24 GB+
- ❌ 70B models (Llama 3.3 70B, Qwen 2.5 72B) — needs 48 GB+
Across 13 community runs from 7 sources, the NVIDIA GeForce RTX 3080 Ti generates a median 89.7 tok/s on 7–9B models at Q4 (per Hardware Corner).
