Which GPUs Can Run ELYZA Japanese Llama 2 13B Instruct?

BF16 · 28.0 GB

ELYZA Japanese Llama 2 13B Instruct (BF16) requires 28.0 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 37+ GB is recommended. Using the full 4K context window can add up to 1.7 GB, bringing total usage to 29.7 GB. 1 GPU can run it, including NVIDIA GeForce RTX 5090.

All compatible consumer-level GPUs are running near their VRAM limit. You may also want to consider professional GPUs (e.g., NVIDIA A100, H100) which offer significantly more VRAM. For more headroom and better throughput, consider a multi-GPU configuration with tensor parallelism (supported by tools like vLLM, llama.cpp, or text-generation-inference).

Frequently Asked Questions

How much VRAM does ELYZA Japanese Llama 2 13B Instruct need?

ELYZA Japanese Llama 2 13B Instruct requires 28.0 GB of VRAM at BF16. Full 4K context adds up to 1.7 GB (29.7 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 13B × 16 bits ÷ 8 = 26 GB

KV Cache + Overhead 2 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead 3.7 GB (at full 4K context)

Can I run ELYZA Japanese Llama 2 13B Instruct on a Mac?

ELYZA Japanese Llama 2 13B Instruct requires at least 28.0 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 ELYZA Japanese Llama 2 13B Instruct locally?

Yes — ELYZA Japanese Llama 2 13B Instruct can run locally on consumer hardware. At BF16 quantization it needs 28.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is ELYZA Japanese Llama 2 13B Instruct?

At BF16, ELYZA Japanese Llama 2 13B Instruct can reach ~104 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 MI300X5300 ÷ 28.0 × 0.55 = ~104 tok/s

Estimated speed at BF16 (28.0 GB)

~104 tok/s
~78 tok/s
~64 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
