Frequently Asked Questions
- How much VRAM does Z Image Turbo need?
Z Image Turbo requires 13.5 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 6.2B × 16 bits ÷ 8 = 12.3 GB
KV Cache + Overhead ≈ 1.2 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF1613.5 GB- Can I run Z Image Turbo on a Mac?
Z Image Turbo requires at least 13.5 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 Z Image Turbo locally?
Yes — Z Image Turbo can run locally on consumer hardware. At BF16 quantization it needs 13.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Z Image Turbo?
At BF16, Z Image Turbo can reach ~355 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~48 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 ÷ 13.5 × 0.65 = ~384 tok/s
Estimated speed at BF16 (13.5 GB)
~384 tok/s~48 tok/s~384 tok/s~355 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Z Image Turbo?
At BF16, the download is about 12.31 GB.
- Which GPUs can run Z Image Turbo?
26 consumer GPUs can run Z Image Turbo at BF16 (13.5 GB). Top options include AMD Radeon RX 7900 XTX, NVIDIA GeForce RTX 3090, NVIDIA GeForce RTX 3090 Ti, AMD Radeon RX 6800. 7 GPUs have plenty of headroom for comfortable inference.
- Which devices can run Z Image Turbo?
49 devices with unified memory can run Z Image Turbo at BF16 (13.5 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Asus ROG Flow Z13 (2025, Ryzen AI Max+ 395, 128 GB), Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
