Which GPUs Can Run Aurora SCE 12B?

BF16 · 25.2 GB

Aurora SCE 12B (BF16) requires 25.2 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 33+ GB is recommended. Using the full 1024K context window can add up to 209.3 GB, bringing total usage to 234.5 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 Aurora SCE 12B need?

Aurora SCE 12B requires 25.2 GB of VRAM at BF16. Full 1024K context adds up to 209.3 GB (234.5 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 12.2B × 16 bits ÷ 8 = 24.5 GB

KV Cache + Overhead 0.7 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead 210 GB (at full 1024K context)

Can I run Aurora SCE 12B on a Mac?

Aurora SCE 12B requires at least 25.2 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 Aurora SCE 12B locally?

Yes — Aurora SCE 12B can run locally on consumer hardware. At BF16 quantization it needs 25.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Aurora SCE 12B?

At BF16, Aurora SCE 12B can reach ~116 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 ÷ 25.2 × 0.55 = ~116 tok/s

Estimated speed at BF16 (25.2 GB)

~116 tok/s
~86 tok/s
~72 tok/s

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