Fits in 16 GB VRAM with room to spare. Best for on-device, mobile, chat on RTX 5070 Ti.
The RTX 5070 Ti pairs 16GB of GDDR7 with 896 GB/s of bandwidth, the highest of any 16GB card ModelFit tracks. It matches the RTX 3090's speed on 8B models (an estimated 87 tok/s) and runs 14B parameter models at an estimated 54 tok/s. The 2026 memory shortage has lifted it above MSRP like every other tier.
The best local LLM for the RTX 5070 Ti is Gemma 4 E4B (Q8) at ~88 tok/s on its 16GB VRAM. It uses ~7.5GB of VRAM; the RTX 5070 Ti handles up to 14B parameter models at Q4. A 14B model at Q4 runs at ~54 tok/s.
Sizing rule: a Q4 model needs about 0.6 GB of VRAM per billion parameters, and ModelFit budgets 90% of this card's 16GB for weights, context, and KV-cache. The per-size table below uses that same budget. Other strong fits: Qwen3.5 9B Instruct (Q8) (9B, ~10.7GB) and Qwen3 8B (Q8) (8B, ~8.1GB). Gemma 4 E4B (Q8) runs at an estimated 88 tok/s on this card. What it will not run: a 32B model does not fit in VRAM alone, so it spills to system RAM over PCIe and slows sharply.
Speeds are ModelFit estimates from memory bandwidth and model size, not measured benchmarks.

| Model Size | Est. Speed | Fit on 16GB |
|---|---|---|
| 7B | ~97 tok/s | Fits in VRAM |
| 14B | ~54 tok/s | Fits in VRAM |
| 20B MoE (3.6B active) | ~83 tok/s | Fits in VRAM |
| 32B | ~5 tok/s | CPU offload (slow) |
| 35B MoE (3B active) | ~53 tok/s | CPU offload (slow) |
| 70B | ~1 tok/s | CPU offload (slow) |
| 120B MoE (5.1B active) | ~12 tok/s | CPU offload (slow) |

ModelFit estimates, not measured benchmarks: anchored to an 8B-class Q4_K_M model at 16K context on the RTX 5070 Ti's 896 GB/s bandwidth, then scaled by model size. MoE rows scale by active parameters (decode reads only the active experts), so a 35B MoE runs far faster than a dense 32B. "CPU offload" sizes exceed the 16GB VRAM; dense models slow to a crawl there, MoE models degrade less because hot experts stay GPU-resident.
Context costs VRAM too. Gemma 4 E4B (Q8) loads ~7.5 GB of weights; at 16k context the KV cache adds ~2.0 GB (still fits the ~14 GB usable VRAM), and at 64k it adds ~8.0 GB (exceeds the budget, use a smaller quant or a q8_0 KV cache).
KV-cache figures assume an fp16 cache, the llama.cpp/Ollama default. Standard GQA models use a size-class estimate (8 KV heads x 128 head dim class); hybrid linear-attention models (Qwen3.5/3.6, Qwen3-Next) use the exact per-token cost from their published config, since only their sparse full-attention layers cache KV. A q8_0 KV cache roughly halves either figure. Estimates, not measurements.

16GB GDDR7 at 896 GB/s is the highest bandwidth of any 16GB card ModelFit tracks. The RTX 5070 Ti loads 14B models at Q4 with 5-6GB to spare and runs them at an estimated 54 tok/s. On 8B models its bandwidth pushes tokens out at an estimated 87 tok/s, matching the RTX 3090 (24GB). The 896 GB/s bandwidth is 33% higher than the RTX 5080 on a per-GB basis, which keeps token generation fast for models that fit its 16GB capacity.

The RTX 5070 Ti has 16GB GDDR7 VRAM with 896 GB/s bandwidth. About 15.5GB is usable for models. This comfortably fits all 14B models at Q4 and some 27B models at lower quantization.
Up to 14B parameter models at Q4 quantization fit perfectly. Popular picks: Qwen 2.5 14B, DeepSeek-R1 14B, Phi-3 14B. You can also squeeze in 27B models at Q3, though with reduced quality.
The RTX 5070 Ti is arguably the best value GPU for local AI in 2026. It matches the RTX 3090 in 8B speed (~87 tok/s est.), runs 14B models at an estimated 54 tok/s, and still costs well under the RTX 5080 while delivering similar throughput.
The RTX 3090 has 24GB VRAM vs 16GB, allowing 32B models. But the 5070 Ti matches it in 8B speed (~87 tok/s est.) and costs less new. Choose the 3090 (used, ~$900) for 32B models, or the 5070 Ti for 14B models with modern efficiency.
Both have 16GB VRAM. The 5080 is 8% faster (an estimated 94 vs 87 tok/s on 8B) but costs roughly a third more. For most users, the 5070 Ti delivers 93% of the speed at 75% of the price, a clear value winner.
The RTX 5070 Ti's 16GB of VRAM cannot fit a 32B model comfortably. The largest size class it fits is 20B MoE (3.6B active), at an estimated 83 tok/s. The largest individual model in the catalog that fits is LFM2 24B-A2B Instruct (24B).
