Frequently Asked Questions
- How much VRAM does SynLogic 7B need?
SynLogic 7B requires 15.7 GB of VRAM at BF16. Full 131K context adds up to 7.4 GB (23.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.6B × 16 bits ÷ 8 = 15.2 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 7.9 GB (at full 131K context)
VRAM usage by quantization
BF1615.7 GBBF16 + full context23.1 GB- Can I run SynLogic 7B on a Mac?
SynLogic 7B requires at least 15.7 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 SynLogic 7B locally?
Yes — SynLogic 7B can run locally on consumer hardware. At BF16 quantization it needs 15.7 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is SynLogic 7B?
At BF16, SynLogic 7B can reach ~186 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~42 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 15.7 × 0.55 = ~186 tok/s
Estimated speed at BF16 (15.7 GB)
~186 tok/s~42 tok/s~139 tok/s~115 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of SynLogic 7B?
At BF16, the download is about 15.23 GB.
- Which GPUs can run SynLogic 7B?
17 consumer GPUs can run SynLogic 7B at BF16 (15.7 GB). Top options include AMD Radeon RX 7900 XTX, NVIDIA GeForce RTX 3090, NVIDIA GeForce RTX 3090 Ti, AMD Radeon RX 6800. 5 GPUs have plenty of headroom for comfortable inference.
- Which devices can run SynLogic 7B?
27 devices with unified memory can run SynLogic 7B at BF16 (15.7 GB), including Mac Mini M4 (16 GB), Mac Mini M4 (32 GB), Mac Mini M4 Pro (24 GB), Mac Mini M4 Pro (48 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
