Best NVIDIA mini PC for AI
Last updated
The best NVIDIA mini PC for AI is Olares One for image, video and models up to about 32B, and DGX Spark or the ASUS Ascent GX10 for models that need 128 GB. All three run CUDA and differ in memory, CPU architecture and price.

Which is the best NVIDIA mini PC for AI?
It depends on model size. Olares One, with a 24 GB RTX 5090 Mobile, is our pick for image and video generation and models up to about 32B. DGX Spark and the ASUS Ascent GX10, both built on the GB10 chip with 128 GB of unified memory, are the picks for 70B and larger.
| Olares One | NVIDIA DGX Spark | ASUS Ascent GX10 | |
|---|---|---|---|
| GPU | RTX 5090 Mobile | GB10 (Blackwell) | GB10 (Blackwell) |
| Memory for models | 24 GB GDDR7 VRAM | 128 GB unified, 273 GB/s | 128 GB unified, LPDDR5X-8533 |
| CPU | Intel Core Ultra 9 275HX (x86, 24 cores) | 20-core Arm | 20-core Arm |
| OS | Olares OS | DGX OS | NVIDIA DGX OS |
| Size, weight | 320 x 197 x 55 mm, 2.15 kg | 150 x 150 x 50.5 mm, 1.2 kg | 150 x 150 x 51 mm, 1.48 kg |
| Power supply | 330 W | 240 W | 240 W |
| Price (12-13 Nov 2026) | 4,999 USD list | 6,950 USD (4 TB) | 5,999 USD (1 TB, out of stock) |
Dedicated VRAM or unified memory?
Dedicated VRAM runs models that fit at full GPU speed, and unified memory holds models that would not fit at all. Olares One has 24 GB of GDDR7 on the GPU. The GB10 shares 128 GB between CPU and GPU, at a bandwidth NVIDIA lists as 273 GB/s for DGX Spark.
By the approximate 4-bit rule, a 70B model needs about 40 GB and a 120B model about 65 GB. Both fit on the GB10. Neither fits in 24 GB.
Does x86 or Arm matter?
It matters if you rely on software without Arm builds. Olares One uses an Intel x86 CPU, while DGX Spark and the GX10 use a 20-core Arm CPU. NVIDIA supports its own AI stack on GB10, and Olares argues that x86 with CUDA avoids porting work some open-source tools still need on Arm.
x86 also lets Olares One dual-boot Windows, which Olares documents in its FAQ.
Which one should you buy?
Buy Olares One for FLUX, Wan video, models up to about 32B and a box several people share. Buy the GX10 for 128 GB on CUDA at the lower GB10 price, once it is back in stock. Buy DGX Spark for the same chip with a 4 TB drive, at 6,950 USD on the NVIDIA store.
In Olares' own test, Olares One ran Qwen3-30B-A3B at 157 tokens/s for one request. Our data has no matching test for the GB10 machines. See the 128 GB guide for the AMD alternatives and the video guide for video work.
Questions & answers
Is there a mini PC with an RTX 5090?
Olares One uses the RTX 5090 Mobile with 24 GB of GDDR7, according to Olares. The desktop RTX 5090 card has 32 GB and a 575 W rating according to NVIDIA, which calls for a full-size PC.
Is DGX Spark a mini PC?
By size, yes. NVIDIA lists 150 x 150 x 50.5 mm and 1.2 kg. NVIDIA sells it as a personal AI supercomputer.
