RTX 5070 Ti hits local LLM sweet spot

The 12GB VRAM barrier is the new standard for "speed-first" local inference, with GDDR7 and Blackwell architecture providing a massive bandwidth leap for 2026.

• –Llama 4 Scout (8B) and Mistral Small 4 (12B) achieve 100+ t/s, making them ideal for seamless real-time coding assistants and research workflows.
• –64GB of DDR5 system RAM is essential for "spillover" usage, allowing users to run 30B+ reasoning models like DeepSeek-R1-Distill-Qwen-14B when quality outweighs speed.
• –FlashAttention 3 and 4-bit KV cache quantization are now mandatory optimizations to maximize context windows on 12GB cards.
• –LM Studio 0.4.x has emerged as the preferred stack for Windows 11 users, offering precise VRAM prediction for Blackwell's 5th-gen Tensor cores.
