Which should you choose?

CHOOSE H100 IF

Your models fit comfortably in 80 GB and you want lower cost and wider availability.

CHOOSE H200 IF

You serve 70B+ models or many users at once: the extra memory holds bigger models and more KV cache, and the extra bandwidth speeds up token generation.

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.

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.

  1. STEP 01 · THIS TOOL

    Size it

    Work out the GPU memory your models need and which GPUs or servers can hold them.

  2. 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.

  3. 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.

H100 vs H200 questions

What is the difference between the H100 and the H200?

The H200 has the same Hopper compute as the H100 but 76% more memory (141 GB of HBM3e vs 80 GB) and 43% more bandwidth (4.8 TB/s vs 3.35 TB/s).

H100 vs H200: which is better for LLM inference?

For generating tokens, the H200 is faster: it has 4.8 TB/s of memory bandwidth versus 3.35 TB/s, and LLM token generation is mostly limited by bandwidth. The H200 holds larger models and more users’ context with 141 GB of memory versus 80 GB. Choose the H100 if your models fit comfortably in 80 GB and you want lower cost and wider availability. Choose the H200 if you serve 70B+ models or many users at once: the extra memory holds bigger models and more KV cache, and the extra bandwidth speeds up token generation.

Can the H100 and H200 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 H100 runs it on one GPU at about 86 tokens/s at most for one user, and the H200 runs it on one GPU at about 124 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 H100 cost compared with the H200?

H100: No list price: sold in servers through OEMs and cloud providers. H200: No list price: sold in servers through OEMs and cloud providers. 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.
