This $3,200 Mini PC Claims to Beat an RTX 4090 at Local AI — Here’s How

Gmktec Evo-X3 Mini PC: A desktop GPU that costs $1,500 on its own. A chip that runs large AI models on 128GB of shared memory. A box small enough to sit behind a monitor. The Gmktec Evo-X3 is a genuinely unusual machine — and Gmktec’s claim that it outperforms an RTX 4090 in specific local AI workloads is either one of the boldest marketing lines of the year, or a sign of just how much the mini PC category has changed.

The 96GB VRAM Trick

Here’s the engineering choice that makes this machine interesting. Because the Ryzen AI Max+ 395 uses unified memory — where the CPU and GPU share the same pool — Gmktec lets you allocate up to 96GB of that 128GB as VRAM. Dedicated desktop GPUs, including the RTX 4090, max out at 24GB of VRAM. That gap matters enormously for running large local language models, where model size is often the hard ceiling. Gmktec says the Evo-X3 can run Qwen3 235B in LM Studio and benchmarks faster than an RTX 4090 in that specific workload — not in gaming, not in rendering, but in LLM token generation speed, where memory capacity is the bottleneck.

OCuLink: The Safety Valve

The 96GB VRAM story is compelling for AI, but anyone who also wants to game on this machine will run into the integrated Radeon 8060S’s limits fast. That’s where the native OCuLink port earns its place — it lets you plug in a full-size desktop GPU (RTX 40-series or 50-series) when you need it. The same port feature appeared in the OneXPlayer G1 gaming handheld, where OCuLink support made it genuinely dual-purpose for gaming and productivity. The Evo-X3 takes the same approach, just in a stationary form factor.

Pricing and Availability

These are China launch prices — global pricing may shift slightly. No India-specific availability has been confirmed yet, but given AMD’s growing footprint in the Indian professional PC space — including the AMD x S8UL partnership backing India’s top esports org and the broader RTX Spark and AI laptop wave coming this fall — demand for local AI compute hardware at this tier is only heading in one direction.

The Bottom Line

The Evo-X3 isn’t trying to be everything. It’s a single-purpose machine for people who want to run large AI models locally without a cloud subscription, in a box that doesn’t require a separate PC tower and GPU. At $3,200, it’s expensive — but compared to building an equivalent local AI rig with a separate CPU, motherboard, and 24GB GPU, the maths get closer than you’d expect. The RTX 4090 claim needs independent verification, but the underlying logic — that 96GB of available VRAM beats 24GB for large models regardless of raw GPU compute — is real.
