Frequently Asked Questions
- How much VRAM does Dolphin 2.9.1 Llama 3 70B need?
Dolphin 2.9.1 Llama 3 70B requires 142.1 GB of VRAM at BF16. Full 8K context adds up to 2.0 GB (144.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 70.6B × 16 bits ÷ 8 = 141.1 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 3 GB (at full 8K context)
VRAM usage by quantization

No — Dolphin 2.9.1 Llama 3 70B requires at least 142.1 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- Can I run Dolphin 2.9.1 Llama 3 70B on a Mac?
Dolphin 2.9.1 Llama 3 70B requires at least 142.1 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Dolphin 2.9.1 Llama 3 70B locally?
Yes — Dolphin 2.9.1 Llama 3 70B can run locally on consumer hardware. At BF16 quantization it needs 142.1 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Dolphin 2.9.1 Llama 3 70B?
At BF16, Dolphin 2.9.1 Llama 3 70B can reach ~21 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 142.1 × 0.55 = ~21 tok/s
Estimated speed at BF16 (142.1 GB)
AMD Instinct MI300X~21 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Dolphin 2.9.1 Llama 3 70B?
At BF16, the download is about 141.11 GB.
- Which GPUs can run Dolphin 2.9.1 Llama 3 70B?
No single consumer GPU has enough VRAM to run Dolphin 2.9.1 Llama 3 70B at BF16 (142.1 GB). Multi-GPU or professional hardware is required.
- Which devices can run Dolphin 2.9.1 Llama 3 70B?
4 devices with unified memory can run Dolphin 2.9.1 Llama 3 70B at BF16 (142.1 GB), including Mac Pro M2 Ultra (192 GB), Mac Studio M2 Ultra (192 GB), NVIDIA DGX A100 640GB, NVIDIA DGX H100. Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
