GeForce RTX 3080 10GB Price, VRAM & Local LLMs

NVIDIA's RTX 3080 10GB (2020) is a high-end gaming card that runs Gemma 4 12B at 4-bit at about 72 tokens/s, but it can't fit 27B-class models. Most cards on the market are used, so tell the 10GB, the 12GB and the modded 20GB versions apart.

What LLMs can a single GeForce RTX 3080 10GB run?

A single RTX 3080 10GB is best with models up to 12B at 4-bit, where a 12B gets around 130K of context. 27B-class dense models don't fit even at 2-bit; 30B-class MoE models need their experts in system RAM, and Qwen3.6 35B A3B at 4-bit runs at about 51 tokens/s.

RunsFits fully in VRAM; speed is estimated from VRAM bandwidth.

Needs RAM offloadMoE only: expert weights sit in system RAM, so speed is estimated from 70 GB/s RAM bandwidth.

Too bigWon’t fit on one card at this quantization, even with RAM offload.

Full calculation rules are on the Methodology page.

Who it suits

Good fit

  1. Fast generation with small models matters to you

    Qwen3.5 9B at 4-bit runs at about 88 tokens/s with 118K of context

  2. You want small models at 8-bit

    Gemma 4 E4B at 8-bit fits entirely on the card with 85K of context

  3. Upgrading an older motherboard

    It's wired for all 16 PCIe 4.0 lanes, so it still gets 3.0 x16 on a PCIe 3.0 board

Not a good fit

  1. You want 27B-class models

    Qwen3.8 27B at 2-bit needs 9.8 GB, and with context added it won't fit in 10GB of VRAM

  2. You want a 9B at 8-bit

    Qwen3.5 9B at 8-bit needs 9.5 GB, and with context and runtime overhead added it won't fit in 10GB of VRAM

Before you buy

  1. Don't mix up the three 3080s

    The RTX 3080 12GB, released in 2022, has 2GB more VRAM, a 384-bit bus and 912 GB/s of bandwidth, so it runs models faster and the numbers on this page don't apply to it. A “3080 20G” in a listing is a modded card and isn't covered here either. If a listing just says “3080”, ask the seller for a GPU-Z screenshot and check for 10GB of VRAM and 8704 cores.

  2. On a used card, check the memory temperature first

    The 3080's GDDR6X memory runs hot, and on a card that's been in use for a few years the thermal pads may have degraded. Before buying, ask the seller to run a load for a while and watch Memory Junction Temperature (the VRAM temperature) in GPU-Z; be careful if it won't come down.

  3. At 320W, the card needs a solid power supply

    NVIDIA recommends a 750W power supply for the system. The Founders Edition is dual-slot and 285 mm long, powered through a 12-pin connector, with an adapter for two 8-pin cables in the box. Most partner cards use two or three 8-pin connectors directly and are longer, so measure your case before installing one.
