Frequently Asked Questions
- How much VRAM does Mark 1x 9B need?
Mark 1x 9B requires 18.5 GB of VRAM at BF16. Full 262K context adds up to 34.1 GB (52.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 9.0B × 16 bits ÷ 8 = 17.9 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 34.7 GB (at full 262K context)
VRAM usage by quantization
BF1618.5 GBBF16 + full context52.6 GB- Can I run Mark 1x 9B on a Mac?
Mark 1x 9B requires at least 18.5 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 Mark 1x 9B locally?
Yes — Mark 1x 9B can run locally on consumer hardware. At BF16 quantization it needs 18.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Mark 1x 9B?
At BF16, Mark 1x 9B can reach ~260 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~36 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 ÷ 18.5 × 0.65 = ~281 tok/s
Estimated speed at BF16 (18.5 GB)
~281 tok/s~36 tok/s~281 tok/s~260 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Mark 1x 9B?
At BF16, the download is about 17.91 GB.
- Which GPUs can run Mark 1x 9B?
8 consumer GPUs can run Mark 1x 9B at BF16 (18.5 GB). Top options include NVIDIA GeForce RTX 5090, AMD Radeon RX 7900 XT, AMD Radeon RX 7900 XTX. 1 GPU have plenty of headroom for comfortable inference.
- Which devices can run Mark 1x 9B?
41 devices with unified memory can run Mark 1x 9B at BF16 (18.5 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.
