NVIDIA RTX 3060 12GB

The NVIDIA RTX 3060 12GB has 12 GB VRAM and 360 GB/s memory bandwidth. It can run 30 of our 97 tracked models natively in VRAM at 8k context.

With 12 GB GDDR6, the NVIDIA RTX 3060 12GB is a consumer-tier GPU that can run 30 models natively. This site's calculator puts Llama 3.1 8B at 30.6 tok/s at Q6_K (8.6 GB) and 39.4 tok/s at Q4_K_M (6.7 GB), both fit natively at 8k context. Qwen2.5 14B is the real ceiling: Q4_K_M (11.8 GB) actually spills into system RAM once overhead is counted, so Q3_K_M (9.7 GB, 27 tok/s) is the largest quant that stays fully in VRAM. 27B+ models need CPU offload at any practical quant.

The NVIDIA RTX 3060 12GB is a budget Ampere GPU with a surprisingly generous 12GB GDDR6 on a 192-bit bus at 360 GB/s. The high VRAM-to-price ratio made it a community favorite for local LLM experimentation, running 7B models at Q5–Q8 and 13B models at Q4 with some headroom. Bandwidth is the limiting factor for inference speed.

NVIDIA RTX 3060 12GB: Announced at CES on January 12, 2021 and on sale five weeks later (February 25) at a $329 MSRP, built on the Ampere GA106 die (3,584 CUDA cores, 170W TDP, PCIe 4.0 x16). Some 2022-production units shipped on a cut-down GA104-150 die instead during the chip shortage; VRAM, bus width, and bandwidth are identical either way.

This site's calculator puts Llama 3.1 8B at 30.6 tok/s at Q6_K (8.6 GB) and 39.4 tok/s at Q4_K_M (6.7 GB), both fit natively at 8k context. Qwen2.5 14B is the real ceiling: Q4_K_M (11.8 GB) actually spills into system RAM once overhead is counted, so Q3_K_M (9.7 GB, 27 tok/s) is the largest quant that stays fully in VRAM. 27B+ models need CPU offload at any practical quant.

Compute capability 8.6, full, mature CUDA support with no version caveats; every modern llama.cpp or Ollama build works out of the box. The 12GB capacity itself wasn't an AI-era design choice: NVIDIA's own 192-bit memory bus only splits cleanly into 6GB or 12GB configurations, so 12GB was the higher of two options in 2021, not a deliberate hobbyist play. That accident left it with more VRAM than the RTX 3060 Ti and RTX 3070 (8GB each), the RTX 3080 (10GB, a genuinely higher-tier card at the time), and even the RTX 4060 Ti's 8GB base config two years later, which is what actually made it a budget local-LLM favorite.

More VRAM than three newer, faster cards

VRAM and bandwidth don't move together across NVIDIA's stack; a card can lead on one and trail on the other. Plotting this card against three cards released after it, all nominally a step up:

VRAM and memory bandwidth, from each card's real spec sheet. A card further right holds bigger models; a card further up decodes them faster once they fit.

This card's 12GB beats the RTX 4060 (8GB) and RTX 5060 (8GB), one and two generations newer, and even the RTX 3080 (10GB), a genuinely higher-tier card from the same generation. Bandwidth tells a mixed story: at 360 GB/s it trails the RTX 3080 (760) and both Blackwell 50-series cards here (448 each), but it's actually faster than the RTX 4060 and RTX 4060 Ti 16GB (272 and 288 GB/s); Ada's 8-16GB tier cut bandwidth harder than the Ampere or Blackwell generations on either side of it. For a local LLM, VRAM decides what fits; bandwidth decides how fast it runs once it does; this card was built lopsided toward the first.
