Frequently Asked Questions
- How much VRAM does Hermes 2 Theta Llama 3 70B need?
Hermes 2 Theta Llama 3 70B requires 43.3 GB of VRAM at Q4_K_M, or 71.5 GB at Q8_0. Full 8K context adds up to 2.0 GB (45.3 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 70.6B × 4.8 bits ÷ 8 = 42.3 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
Q4_K_M43.3 GBQ4_K_M + full context45.3 GB- Can NVIDIA GeForce RTX 4090 run Hermes 2 Theta Llama 3 70B?
Yes, at IQ2_S (23.0 GB) or lower. Higher quantizations like IQ2_M (24.8 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Hermes 2 Theta Llama 3 70B?
For Hermes 2 Theta Llama 3 70B, Q4_K_M (43.3 GB) offers the best balance of quality and VRAM usage. Q4_K_L (44.2 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 20.4 GB.

- Can I run Hermes 2 Theta Llama 3 70B on a Mac?
Hermes 2 Theta Llama 3 70B requires at least 20.4 GB at IQ2_XXS, 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 Hermes 2 Theta Llama 3 70B locally?
Yes — Hermes 2 Theta Llama 3 70B can run locally on consumer hardware. At Q4_K_M quantization it needs 43.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Hermes 2 Theta Llama 3 70B?
At Q4_K_M, Hermes 2 Theta Llama 3 70B can reach ~67 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 ÷ 43.3 × 0.55 = ~67 tok/s
Estimated speed at Q4_K_M (43.3 GB)
~67 tok/s~50 tok/s~42 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Hermes 2 Theta Llama 3 70B?
At Q4_K_M, the download is about 42.33 GB. The full-precision Q8_0 version is 70.55 GB. The smallest option (IQ2_XXS) is 19.40 GB.
- Which GPUs can run Hermes 2 Theta Llama 3 70B?
