What they mean for running LLMs
For large language models, memory decides which models fit and how many users you can serve, and memory bandwidth decides how fast each user gets tokens. These are planning figures for one GPU or system using a 4-bit model.
| For LLMs | DGX Spark | ASUS Ascent GX10 |
|---|---|---|
| Usable for models | About 109 GB | About 109 GB |
| Largest dense model at 4-bit (1 user, short context) | About 170B parameters | About 170B parameters |
| Llama 3.3 70B at 4-bit, single-user speed ceiling | About 7 tokens/s | About 7 tokens/s |

Models in amber need several of these GPUs working as one. Buying the GPUs is the easy part. Vanik Edge OS splits the model across them, keeps it running if a server fails and manages it all from one console. See how Edge OS clusters GPU servers
FROM SIZING TO RUNNING
Sizing the hardware is the easy part.
Getting several GPUs to work as one system for a whole company is where most projects slow down. That is the part Vanik Edge OS does for you.
STEP 01 · THIS TOOL
Size it
Work out the GPU memory your models need and which GPUs or servers can hold them.
STEP 02 · VANIK EDGE OS
Cluster it
Edge OS joins your GPU servers into one cluster, splits a large model across them and keeps it running if a server fails. NVIDIA and AMD servers work side by side.
STEP 03 · VANIK EDGE OS
Run it
Your team gets AI apps with single sign-on and an audit trail, managed from one console, with your data staying inside your building.
DGX Spark vs ASUS Ascent GX10 questions
What is the difference between the DGX Spark and the ASUS Ascent GX10?
They are the same machine inside: NVIDIA’s GB10 Grace Blackwell chip, 128 GB of unified memory at 273 GB/s and 1 PFLOP of sparse FP4. They differ in storage, chassis and price.
DGX Spark vs ASUS Ascent GX10: which is better for LLM inference?
Both have the same 273 GB/s of memory bandwidth, so they generate tokens at similar speeds when a model fits on both. Choose the DGX Spark if you want NVIDIA’s own Founders Edition with 4 TB of storage. Choose the ASUS Ascent GX10 if you want the same performance for less, with a 1 TB or 2 TB option.
Can the DGX Spark and ASUS Ascent GX10 run Llama 3.3 70B?
Llama 3.3 70B needs about 46 GB of memory at 4-bit for one user with 8K context. The DGX Spark runs it on one unit at about 7 tokens/s at most for one user, and the ASUS Ascent GX10 runs it on one unit at about 7 tokens/s at most for one user. Speeds are theoretical ceilings from memory bandwidth; real speeds are usually 50 to 80% of that.
How much does the DGX Spark cost compared with the ASUS Ascent GX10?
DGX Spark: US$3,999 at launch (4 TB). ASUS Ascent GX10: Below DGX Spark; varies by storage. Data center GPUs are usually bought as part of 4- or 8-GPU servers, so compare full-system quotes.
How are these numbers calculated?
Memory, bandwidth, compute and power are manufacturer specifications. Model memory needs come from our VRAM calculator: weights plus KV cache plus about 5 to 10% runtime overhead, keeping 10% of each GPU free (15% on GB10 systems, 25% on Mac). The speed ceiling is memory bandwidth divided by the model’s weight size. All figures are planning estimates.
