What is the NVIDIA V100S?

The V100S is a GPU from NVIDIA on the Volta architecture, an accelerator for AI training, inference and high-performance computing. It is a PCIe add-in card, so it fits standard servers and workstations. V100S full specifications →

Can I rent the V100S in the cloud?

Yes. Cloud providers tracked by Flopper rent the V100S by the hour, and the pricing page compares their current rates and the price history side by side. V100S rental prices →

How does the V100S compare with other accelerators?

This page sets the V100S against the ATOM-Max. The V100S is the older generation of the two. This is a cross-vendor matchup, NVIDIA against Rebellions, and both ship as a PCIe card, so they fit the same class of system. The compare tool builds the same comparison for any two parts in the catalogue. All GPU comparisons →

Where do the V100S figures come from?

What is the Rebellions ATOM-Max?

The ATOM-Max is an NPU from Rebellions on the ATOM architecture, an accelerator built for AI inference. It is a PCIe add-in card, so it fits standard servers and workstations. ATOM-Max full specifications →

Can I rent the ATOM-Max in the cloud?

Flopper is not tracking any live rental listings for the ATOM-Max yet. The provider directory lists the clouds that rent comparable accelerators on demand. GPU cloud providers →

How does the ATOM-Max compare with other accelerators?

This page sets the ATOM-Max against the V100S. The ATOM-Max is the newer generation of the two. This is a cross-vendor matchup, Rebellions against NVIDIA, and both ship as a PCIe card, so they fit the same class of system. Flopper also compares it head to head with the L40S 48GB and Rebel100, across every published precision, memory and power. ATOM-Max vs L40S 48GB →

FLOPS by Precision

What actually differs

The ATOM-Max is the newer part: ATOM (2024) against the V100S's Volta (2020).

The ATOM-Max carries 32 GB more memory (64 GB against 32 GB), so larger models fit on one GPU before you shard. Bandwidth is 1.1 TB/s against 1.0 TB/s, which sets the ceiling on decode speed.

Power is 250 W against 350 W, and at FP32 the V100S does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

Frequently asked questions

Is the V100S faster than the ATOM-Max?

They are close on paper: both deliver about 130 TFLOPS of dense FP16 throughput. Memory, bandwidth, and power are the deciding differences.

Which should you choose, the V100S or the ATOM-Max?

On raw FP16 throughput the V100S and the ATOM-Max are level, so the decision rests on memory, power and price. Choose the ATOM-Max when the model has to fit on one GPU: it carries 32 GB more memory. The V100S draws 100 W less power, which matters in an air-cooled or power-capped rack.

Which has more memory, the V100S or the ATOM-Max?

The ATOM-Max carries 64 GB of memory versus 32 GB for the V100S. Memory bandwidth is 1.1 TB/s for the V100S and 1.0 TB/s for the ATOM-Max.

How much power do the V100S and the ATOM-Max draw?

The V100S is rated at 250 W TDP and the ATOM-Max at 350 W. On FP32 throughput per watt, the V100S is the more efficient part.

How much do the V100S and the ATOM-Max cost to rent?

Live cloud listings tracked by Flopper price the V100S from $0.88 per GPU-hour across 1 provider, and no live listings yet for the ATOM-Max. The rental section on this page links to every provider, rate and the price history for each GPU.
