Mini PCs built around AMD's Ryzen AI Max+ PRO 495 are starting to appear, and their headline feature is memory: up to 192GB of unified LPDDR5x, up from 128GB on the Ryzen AI Max+ 395 machines that have become popular for running large language models at home. Minisforum revealed its MS-S1 MAX-P495 in a blog post on 12 November 2026, a month after AMD's own Ryzen AI Halo developer PC with the same chip reached US retail.
Forge PC has not tested either machine. This piece is based on AMD's official specifications, Minisforum's announcement and store listing, and VideoCardz's report on the Ryzen AI Halo launch. Neither system is listed for sale in the UK as we write.
What the Ryzen AI Max+ PRO 495 is
AMD's product page lists 16 Zen 5 cores and 32 threads, a boost clock of up to 5.2GHz, 64MB of L3 cache, and a 55W default TDP that manufacturers can configure from 45W to 120W. The integrated Radeon 8065S graphics have 40 compute units running at up to 3,000MHz. The memory interface is 256-bit LPDDR5x at up to 8,533MT/s, with support for up to 192GB. AMD's earlier codename for the chip was Gorgon Halo.
VideoCardz puts the memory bandwidth at 273GB/s, which matches what a 256-bit bus at 8,533MT/s works out to. That is the number to keep in mind. Capacity decides which models fit, and bandwidth largely decides how fast they generate text. A desktop graphics card such as the RTX 5090 has far more bandwidth but only 32GB of VRAM. Our Mac vs PC for local AI comparison covers the same capacity-versus-bandwidth trade-off.
AMD's Ryzen AI Halo: the first 495 system
AMD's Ryzen AI Halo is a small reference PC for developers. AMD's page lists two versions. The Ryzen AI Max+ PRO 495 model offers up to 192GB of memory, up to 55 NPU TOPS and up to 61 FP16 TFLOPS, and AMD says it can run models of up to 300 billion parameters. The Ryzen AI Max+ 395 model has 128GB, up to 50 NPU TOPS and up to 60 TFLOPS, rated for models up to 200 billion parameters. AMD says the system supports Linux and Windows with its ROCm software, and that it is available for purchase and use in the United States.
VideoCardz reported on 12 October that the 495 version had reached Micro Center in the US at $7,299.99, with 192GB of LPDDR5X-8533 and a 2TB SSD. That is $3,300 more than the original 128GB model. VideoCardz adds that AMD supports allocating up to 160GB as graphics memory, enough, it says, for models of more than 300 billion parameters at 4-bit quantisation.
Minisforum MS-S1 MAX-P495
Minisforum's MS-S1 MAX-P495 is the first third-party mini PC we have seen with the chip. Minisforum quotes a 55 TOPS NPU and 131 TOPS of total system AI performance across the CPU, GPU and NPU (AMD's own chip page says up to 132 overall TOPS). It has 192GB of unified memory, of which up to 160GB can be allocated as VRAM, dual 10GbE ports, Wi-Fi 7, two USB4 v2 ports at 80Gbps and two USB4 ports at 40Gbps.
There is a full-length PCIe x16 slot, but Minisforum's blog says it is wired as PCIe 4.0 x4 and does not support dedicated graphics cards. It is meant for extra SSDs, network adapters or controller cards. Minisforum also says initial production runs will be highly limited.
Minisforum's US store listed the 192GB and 2TB configuration at $7,399 (down from a stated regular price of $9,249) and marked it sold out when we checked on 13 November 2026. We did not find a UK listing, and we have not converted the dollar figure, because UK pricing usually includes VAT and different shipping and warranty terms.
Who this is for
These machines are for people who need very large models to fit entirely in memory on one quiet box: developers, researchers, and anyone working with private data who cannot use cloud AI. For most home users they are not the sensible buy. Our best PC for local AI guide covers cheaper builds for running local models, and our how much RAM for local AI guide explains how much memory different model sizes need.
AMD already rates the 128GB Ryzen AI Max+ 395 version for models of up to 200 billion parameters. The jump to 192GB matters mainly if you want to run the very largest open-weight models, or keep several mid-sized models loaded at once. NVIDIA's competing approach for AI PCs is covered in our RTX Spark story.
Our verdict
The Ryzen AI Max+ PRO 495 makes 192GB of unified memory possible in a mini PC, and with up to 160GB usable as graphics memory, that opens up models larger than any single consumer graphics card can hold. But the first systems cost around $7,300 to $7,400 in the US, Minisforum's is sold out and arriving in limited numbers, and neither is listed in the UK. Unless you specifically need more than 128GB for local models, a Ryzen AI Max+ 395 system or a desktop with a large-VRAM GPU is the better-value route for now. We have not tested these machines; this is based on AMD's specifications, Minisforum's 12 November 2026 announcement and VideoCardz's October report.
