Frequently Asked Questions

How much VRAM does Roleplay Xing4.0 29B need?

Roleplay Xing4.0 29B requires 63.9 GB of VRAM at BF16. Full 262K context adds up to 149.2 GB (213.1 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 31.2B × 16 bits ÷ 8 = 62.4 GB

KV Cache + Overhead ≈ 1.5 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 ≈ 150.7 GB (at full 262K context)

Can NVIDIA GeForce RTX 5090 run Roleplay Xing4.0 29B?

No — Roleplay Xing4.0 29B requires at least 63.9 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.

Can I run Roleplay Xing4.0 29B on a Mac?

Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run Roleplay Xing4.0 29B. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 63.9 GB of usable unified memory (RAM minus macOS overhead).

Can I run Roleplay Xing4.0 29B locally?

Yes — Roleplay Xing4.0 29B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Roleplay Xing4.0 29B?

At BF16, Roleplay Xing4.0 29B can reach ~97 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 11.2 GB active ÷ (8000 × 0.65) = 2.15 ms, plus 40 layers × 0.055 ms = 2.20 ms, so 1000 ÷ 4.35 ms = ~230 tok/s

Estimated speed at BF16 (63.9 GB)

~230 tok/s
~230 tok/s
~175 tok/s

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

What's the download size of Roleplay Xing4.0 29B?

At BF16, the download is about 62.43 GB.

Which GPUs can run Roleplay Xing4.0 29B?

No single consumer GPU has enough VRAM to run Roleplay Xing4.0 29B at BF16 (63.9 GB). Multi-GPU or professional hardware is required.

Which devices can run Roleplay Xing4.0 29B?

31 devices with unified memory can run Roleplay Xing4.0 29B at BF16 (63.9 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.
