What can a 12 GB graphics card run locally? Every answer below is the one RigCheck's own checker for that model gives for each 12 GB card in the finder, with 64 GB of system RAM. Nothing on this page is judged separately, and no answer is a formula from the memory size alone.
With 64 GB of system RAM, across the 12 graphics cards with 12 GB of VRAM in RigCheck's finder, the checkers have an answer for 13 of the 16 models, sizes and routes they cover on at least one of them. Placed wholly or partly on the card, by RigCheck's llama.cpp capacity estimates: Mistral Medium 3.5 in llama.cpp (1 of 12), Qwen3.8-27B in llama.cpp (9 of 12, without caveats or conditions on 8), Gemma 4 31B (9 of 12), Gemma 4 26B-A4B (9 of 12), Gemma 4 12B (9 of 12, without caveats or conditions on 8), Gemma 4 E4B (9 of 12, without caveats or conditions on 8), Gemma 4 E2B (9 of 12, without caveats or conditions on 8). On the processor in system RAM alone, the card unused: Qwen3.8-27B in llama.cpp (3 of 12), Gemma 4 31B (3 of 12), Gemma 4 26B-A4B (3 of 12), Gemma 4 12B (3 of 12), Gemma 4 E4B (3 of 12), Gemma 4 E2B (3 of 12). Answers that name no placement (Strata's published requirements, published route and recipe matches, planning budgets; some rest on system RAM alone, as the table says): Qwen3.8-Flash-Next in the Strata engine (all 12), Qwen-Image-2.1 (image generation) (2 of 12), MiniMax H3 (video + audio) (4 of 12), Nemotron 3.5 Bolt 74B-A9B (9 of 12), Nemotron 3.5 Super VL 120B-A12B (9 of 12), FLUX 3 Image Klein (int8, ComfyUI) (8 of 12). Which cards get an answer, and which answer, depends on the card and not only on its memory: the table lists them card by card. The llama.cpp language-model answers are capacity estimates and the Nemotron 3.5, GLM-5.3-Flash and DeepSeek V4.1 Flash answers are published route matches, not measured setups.

Quick setup, as in the home page finder: one card, a 32K context and no image input for the llama.cpp capacity estimates (Nemotron 3.5, GLM-5.3-Flash and DeepSeek V4.1 Flash are matched against published recipes, memory tables and routes at their own context instead (NVIDIA's 64K / 256K recipes; Unsloth's GLM table states no context length; DwarfStar's routes per DeepSeek checkpoint (documented for the September weights, experimental for 1017), not llama.cpp).), the better of Windows and Linux for Strata, an NVMe SSD, 64 GB of system RAM; for the image and video rows, Qwen-Image (a planning budget): base model, INT8, 512×512, batch one, no reference images; Kolibri-1: the official FP8 route at a 32K context; MiniMax H3: local H3-Base FL2VA recipes, assuming an NVMe drive; Nemotron 3.5: Bolt and Super VL on one card with the RAM given; FLUX 3 Image Klein: Black Forest Labs' int8 ComfyUI route on the card. "With caveats" means part of the model sits in system RAM (slower), an unmeasured peak, or a route the checker marks conditional. Cards with the same answer, word for word, share a line; "RTX 3070 / 3070 Ti" is two cards the checkers treat alike. There is no speed line, because speeds differ between cards with the same memory; where a checker's own conditions mention a speed, they name the hardware it was measured on. Each card's page and the full checkers show measured speeds, labeled. Pick your card in a checker for your exact setup.
What system RAM changes
The checkers' own answers for the same cards with 32 GB instead of 64 GB of system RAM, and, for 64 GB, the smallest larger RAM size for which a checker gives a better answer. Parts of a large model that do not fit on the card are kept in system RAM, so RAM matters as much as VRAM for the big mixture-of-experts models.

No answer on: GeForce RTX 2060, Radeon RX 7700 XT, Radeon RX 6700 XT. The full checker lets you change the route or recipe settings and lists the files and the published recipe.
Can a 12 GB graphics card run FLUX 3 Image Klein (int8, ComfyUI)?
In RigCheck's quick setup with 64 GB of system RAM, the checker has an answer on 8 of the 12 12 GB cards in the finder. On 6 of 12 cards: GeForce RTX 5070, GeForce RTX 4070 Ti, GeForce RTX 3080 Ti, GeForce RTX 3080, GeForce RTX 3060, GeForce RTX 4080 Laptop: A published route or recipe matches, with caveats: Matches BFL's 8 GB guidance: the int8 files in ComfyUI; BFL: the int8 ComfyUI files run on 8 GB GPUs such as the RTX 3070. Image model, int8 text encoder and VAE together are 11.0 GB; by our reading, on a card smaller than that ComfyUI keeps them on the GPU one at a time and needs system RAM for the rest. BFL gives no RAM figure. The prompt upsampler BFL says not to skip is a 9B model (6.72 GB w4a8, 9.75 GB int8 or 18.8 GB BF16 in ComfyUI); BFL does not say whether its 8 GB figure includes it. When it does not fit with the image model, run it on its own first (BFL's README) or switch it off in the ComfyUI template, with weaker results. On 2 of 12 cards: GeForce RTX 4070 / 4070 Super: A published route or recipe matches, with caveats: Matches BFL's 8 GB guidance: the int8 files in ComfyUI; BFL: the int8 ComfyUI files run on 8 GB GPUs such as the RTX 3070. Image model, int8 text encoder and VAE together are 11.0 GB; by our reading, on a card smaller than that ComfyUI keeps them on the GPU one at a time and needs system RAM for the rest. BFL gives no RAM figure. The prompt upsampler BFL says not to skip is a 9B model (6.72 GB w4a8, 9.75 GB int8 or 18.8 GB BF16 in ComfyUI); BFL does not say whether its 8 GB figure includes it. When it does not fit with the image model, run it on its own first (BFL's README) or switch it off in the ComfyUI template, with weaker results. NVIDIA measured 8.9 seconds per 1024×1024 image on an RTX 4070 (distilled, int8, 16 steps, ComfyUI, upsampler not included); not measured on the 4070 Super. No answer on: GeForce RTX 2060, Radeon RX 7700 XT, Radeon RX 6700 XT, Intel Arc B580. The full checker lets you change the route or recipe settings and lists the files and the published recipe.
Why do 12 GB cards get different answers?
Each checker judges the card itself, with its own support list and the routes its sources name, not only the memory size. On this page that happens for Qwen3.8-Flash-Next in the Strata engine, Qwen3.8-Flash-Next in llama.cpp, Mistral Medium 3.5 in llama.cpp, Qwen3.8-27B in llama.cpp, Gemma 4 (E2B, E4B, 12B, 26B-A4B, 31B) in llama.cpp, Qwen-Image-2.1 (image generation), MiniMax H3 (video + audio), Nemotron 3.5 (Bolt 74B-A9B, Super VL 120B-A12B), FLUX 3 Image Klein (int8, ComfyUI), GLM-5.3-Flash (Unsloth GGUF); the table lists each card's answer. Speeds also differ between cards with the same memory, so this page has no speed line: each card's own page and the full checkers show measured speeds, labeled.
How does system RAM change what a 12 GB card can run?
With 32 GB instead of 64 GB, the answer changes on some or all of these cards for 5 models: Qwen3.8-Flash-Next in the Strata engine, Mistral Medium 3.5 in llama.cpp, Qwen3.8-27B in llama.cpp, Gemma 4 (E2B, E4B, 12B, 26B-A4B, 31B) in llama.cpp, Nemotron 3.5 (Bolt 74B-A9B, Super VL 120B-A12B). With more than 64 GB, a checker gives a better answer for 1 model: Qwen3.8-Flash-Next in llama.cpp. See What system RAM changes for the cards and the answers.
