⚡ Architecture & Throughput Transparency: Single-user decode speed (~0 tok/s) is memory-bandwidth bound at batch size = 1 on NVIDIA RTX 4070 Ti Super (16GB) (672 GB/s). Prompt prefill / TTFT (~0 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).
MoE Memory vs Speed Architecture: While decode throughput scales with the active parameter count (37B parameters streamed per token), all 671B parameters must be resident in VRAM so the dynamic router can route tokens to any expert layer.
Multi-Head Latent Attention (MLA): DeepSeek compresses Key-Value projections into a low-rank latent vector, cutting KV memory footprint by ~85% compared to standard MHA/GQA.

FAQ & Reference

Frequently Asked Questions: DeepSeek-R1 (671B MoE) on NVIDIA RTX 4070 Ti Super (16GB)

How much VRAM does DeepSeek-R1 (671B MoE) need on NVIDIA RTX 4070 Ti Super (16GB)?

At standard 4-bit quantization (Q4_K_M) with 32K context, DeepSeek-R1 (671B MoE) requires 482.94 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will DeepSeek-R1 (671B MoE) achieve on NVIDIA RTX 4070 Ti Super (16GB)?

Based on NVIDIA RTX 4070 Ti Super (16GB)'s 672 GB/s memory bandwidth, expected decode speed is approximately 0 tokens per second.

Can I expand context beyond 32K tokens?

Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
