Frequently Asked Questions
- How much VRAM does Gemma 4 E4B Luchador need?
Gemma 4 E4B Luchador requires 16.5 GB of VRAM at BF16. Full 131K context adds up to 13.9 GB (30.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.0B × 16 bits ÷ 8 = 16 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 14.4 GB (at full 131K context)
VRAM usage by quantization
BF1616.5 GBBF16 + full context30.4 GB- Can I run Gemma 4 E4B Luchador on a Mac?
Gemma 4 E4B Luchador requires at least 16.5 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 Gemma 4 E4B Luchador locally?
Yes — Gemma 4 E4B Luchador can run locally on consumer hardware. At BF16 quantization it needs 16.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Gemma 4 E4B Luchador?
At BF16, Gemma 4 E4B Luchador can reach ~267 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~40 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 16.5 × 0.65 = ~315 tok/s
Estimated speed at BF16 (16.5 GB)
~315 tok/s~40 tok/s~315 tok/s~267 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
