Frequently Asked Questions
How much VRAM does Qwopus3.6 27B Coder need?
Qwopus3.6 27B Coder requires 56.3 GB of VRAM at BF16. Full 262K context adds up to 13.9 GB (70.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 27.8B × 16 bits ÷ 8 = 55.6 GB
KV Cache + Overhead ≈ 0.7 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 ≈ 14.6 GB (at full 262K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Qwopus3.6 27B Coder?
No — Qwopus3.6 27B Coder requires at least 56.3 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
Can I run Qwopus3.6 27B Coder on a Mac?
Yes — Mac Pro M2 Ultra (64 GB) and 41 other Macs can run Qwopus3.6 27B Coder. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 56.3 GB of usable unified memory (RAM minus macOS overhead).
Can I run Qwopus3.6 27B Coder locally?
Yes — Qwopus3.6 27B Coder can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Qwopus3.6 27B Coder?
At BF16, Qwopus3.6 27B Coder can reach ~85 tok/s on AMD Instinct MI350X. 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 ÷ 56.3 × 0.65 = ~92 tok/s
Estimated speed at BF16 (56.3 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Qwopus3.6 27B Coder?
At BF16, the download is about 55.56 GB.
Which GPUs can run Qwopus3.6 27B Coder?
No single consumer GPU has enough VRAM to run Qwopus3.6 27B Coder at BF16 (56.3 GB). Multi-GPU or professional hardware is required.
Which devices can run Qwopus3.6 27B Coder?
52 devices with unified memory can run Qwopus3.6 27B Coder at BF16 (56.3 GB), including ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB), GMKtec EVO-X2 (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.
