MINISFORUM MS-S1 MAX-P495 launches September with 192GB RAM for local AI

MINISFORUM is launching the MS-S1 MAX-P495, a mini workstation designed to run large language models locally on a single desktop unit. This release matters because it consolidates massive memory bandwidth and capacity into a compact form factor, allowing users to deploy 284-billion parameter AI models without relying on cloud infrastructure. Buyers interested in on-device inference for complex reasoning tasks now have a dedicated hardware option that fits on a desk rather than in a data center rack.

Mini workstation features AMD Ryzen AI Max+ PRO 495 processor and 192GB unified memory

The system is built around the AMD Ryzen AI Max+ PRO 495 processor, which serves as the central computing engine for the workstation. MINISFORUM equips this chip with 192GB of LPDDR5X-8533 unified memory, a configuration that eliminates the traditional bottleneck between CPU and GPU data transfer. This unified architecture allows the system to dynamically allocate up to 160GB of that total memory for video RAM usage, prioritizing the needs of large AI workloads over standard graphics rendering.

Specifications

• Processor: AMD Ryzen AI Max+ PRO 495
• Memory: 192GB LPDDR5X-8533
• VRAM Allocation: Up to 160GB
• DeepSeek V4 Flash 284B Performance: 15 Token/s (Q4 quantization)
• 122B Model Performance: 27 Token/s (Q8 quantization)

MINISFORUM reports that this memory configuration enables the device to run the DeepSeek V4 Flash 284B model at 15 tokens per second when using Q4 quantization. The machine also handles 122-billion parameter models at a rate of 27 tokens per second under Q8 quantization settings. These performance figures demonstrate the system's capability to maintain usable inference speeds even when processing models with hundreds of billions of parameters.

The workstation supports context windows of up to 131,000 tokens when operating with Q8 high-precision quantization, allowing the AI to retain extensive conversation history or document context. MINISFORUM states that other hardware configurations for this model should remain consistent with the previously released MS-S1 MAX-395, though specific details for those secondary components are not fully detailed in the current announcement. We looked at MINISFORUM MS-S1 MAX RTX 5070 Mini in our earlier Minisforum coverage.

The MS-S1 MAX-P495 is scheduled to go on sale in September 2024 across global and Chinese markets. MINISFORUM has not yet published specific pricing details for this high-memory configuration, leaving the cost to consumers undetermined at this time. The launch marks a step toward making high-capacity local AI inference accessible through standard desktop hardware rather than specialized server racks.
