Frequently Asked Questions

How much VRAM does Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic need?

Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic requires 3.4 GB of VRAM at Q4_K_M, or 10.6 GB at BF16. Full 131K context adds up to 0.7 GB (4.1 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 5.1B × 4.8 bits ÷ 8 = 3.1 GB

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

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 1 GB (at full 131K context)

Can I run Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic on a Mac?

Yes — Mac Mini M2 (8 GB) and 145 other Macs can run Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 3.4 GB of usable unified memory (RAM minus macOS overhead).

Can I run Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic locally?

Yes — Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic?

At Q4_K_M, Gemma 4 E2B IT Qat Q4 0 Unquantized Heretic can reach ~1404 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~192 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 ÷ 3.4200 × 0.65 = ~1520 tok/s

Estimated speed at Q4_K_M (3.4 GB)

~1521 tok/s
~192 tok/s
~1521 tok/s
~1404 tok/s

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