- Answers from each model's own checker

What runs on an RTX 4070 Ti? Every answer below is the one RigCheck's own checker for that model gives for this card, with 32 GB or 64 GB of system RAM. Nothing on this page is judged separately.
With 64 GB of system RAM, the checkers have an answer for an RTX 4070 Ti (12 GB of VRAM) for 10 of the 13 models, sizes and routes they cover: 5 without caveats (Qwen3.8-Flash-Next in the Strata engine, Qwen3.8-27B in llama.cpp, Gemma 4 12B, Gemma 4 E4B, Gemma 4 E2B); Gemma 4 31B, Gemma 4 26B-A4B, Nemotron 3.5 Bolt 74B-A9B, Nemotron 3.5 Super VL 120B-A12B, FLUX 3 Image Klein (int8, ComfyUI) with caveats (part in system RAM, an experimental path, a planning budget or an unmeasured peak). With 32 GB, 4 without caveats (Qwen3.8-27B in llama.cpp, Gemma 4 12B, Gemma 4 E4B, Gemma 4 E2B). 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.
RTX 4070 Ti: model by model
Language models
| Model (checker) | With 32 GB RAM | With 64 GB RAM |
|---|---|---|
| Qwen3.8-Flash-Next in the Strata engine | ! Runs, with caveats IQ2_XS No measured speed for this hardware and setup yet. Your RAM cannot hold this size's experts (about 46 GB of RAM), so Strata switches to low-RAM mode by itself and reads the experts the card does not hold from the SSD while it answers. Strata: slower, and much slower with a small graphics card; RigCheck has no matching speed for this. For code, the Coder (IQ1_M) runs here with its experts copied into RAM at start; Strata: it is weaker outside code and in languages other than English. | ✓ Runs IQ3_S No measured speed for this hardware and setup yet. Fits by the docs' rule (experts + ~10 GB), with little room to spare: close the browser while it runs. Your card was not benchmarked; this is the closest published card. Less memory bandwidth or VRAM means lower speed. |

Quick setup, as in the home page finder: one RTX 4070 Ti, 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; 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. Speeds appear only where they were measured on this very card in this setup; official estimates and runs on other setups are left out (the full checkers show them, labeled). Pick this card in a checker for your exact setup.

About the RTX 4070 Ti
RTX 4070 Ti: 12 GB GDDR6X of video memory (NVIDIA GeForce RTX 4070 family specifications). For the large mixture-of-experts models here, system RAM matters as much as VRAM: the parts that do not fit on the card are kept in RAM.
This page is the 12 GB RTX 4070 Ti. The RTX 4070 Ti SUPER has 16 GB and fits more; check it in the home page finder.
