Which is the best AI mini PC with 128 GB RAM?
For most buyers, a Ryzen AI Max+ 395 box gives 128 GB for the least money. The GMKtec EVO-X2 was 3,499.99 USD on sale on 12 Nov 2026 and the Minisforum MS-S1 Max 3,959 USD on sale on 13 Nov. Buy DGX Spark or the ASUS GX10 only if you need CUDA with 128 GB.
| Machine | Chip | Price (store, 12-13 Nov 2026) | Included |
|---|---|---|---|
| Framework Desktop | Ryzen AI Max+ 395 | 3,449 USD | DIY Edition, no drive, no OS |
| GMKtec EVO-X2 | Ryzen AI Max+ 395 | 3,499.99 USD (sale; regular 3,999.99 USD) | 1 TB or 2 TB SSD; Windows 11 Pro or Ubuntu |
| Minisforum MS-S1 Max | Ryzen AI Max+ 395 | 3,959 USD (sale; list 4,949 USD) | 2 TB SSD; 4 TB version 4,199 USD |
| Beelink GTR9 Pro | Ryzen AI Max+ 395 | 4,199 USD (was 4,699 USD) | 2 TB SSD, Windows 11 Pro |
| ASUS Ascent GX10 | NVIDIA GB10 | 5,999 USD (out of stock on 12 Nov) | 1 TB, DGX OS |
| NVIDIA DGX Spark | NVIDIA GB10 | 6,950 USD | 4 TB, DGX OS |
Can the GPU use all 128 GB?
No. On a Ryzen AI Max+ 395 box, the CPU, the operating system and the GPU all share the 128 GB, so the GPU gets only part of it, and GMKtec does not state how much. DGX Spark and the GX10 also share one pool of unified memory between CPU and GPU.
Olares One is built differently. It has 96 GB of DDR5-5600 system RAM, upgradable to 128 GB, plus a separate 24 GB of GDDR7 on the GPU. Models run fastest inside the 24 GB. According to Olares' FAQ, the system RAM also holds models that Olares swaps out of the GPU between uses.
What does 128 GB let you run?
It lets you run 70B and 120B models at 4-bit, which need about 40 GB and 65 GB by the approximate rule, with room left for context and a small helper model. That capacity is the reason to buy one. Speed is the trade-off, because shared memory is usually slower than dedicated VRAM.
NVIDIA lists 273 GB/s for DGX Spark's unified memory. The SpecPicks build guide lists 936 GB/s for the 24 GB on a used RTX 3090. Large dense models answer more slowly on shared memory than small models do in fast VRAM.
How do the 128 GB boxes differ?
The four Ryzen boxes share one chip, so what is included sets them apart. The Framework Desktop DIY Edition ships without a drive or OS. The Beelink GTR9 Pro includes a 2 TB SSD, Windows 11 Pro and, per Beelink's page, a 3-year warranty. The EVO-X2 comes with Windows 11 Pro or Ubuntu.
For a first 128 GB box on a budget, we would start with the EVO-X2 at its sale price. If CUDA tools matter, pay more for the GX10 or DGX Spark. If image and video matter more than 70B models, read the FLUX guide and the local LLM guide first.
Questions & answers
Is the Ryzen AI Max+ 395 good for local AI?
For large chat models, yes, because its 128 GB pool can hold 70B and 120B models at 4-bit by the approximate rule. It has no CUDA, so check that your image, video and serving tools support AMD.
Does Olares One have 128 GB?
No. According to Olares, it ships with 96 GB of system RAM, upgradable to 128 GB, plus 24 GB of VRAM on the GPU. Models run on the 24 GB; the system RAM takes spillover, other apps and swapped-out models.
