Can I rent the Yunsui i20 in the cloud?

Flopper is not tracking any live rental listings for the Yunsui i20 yet. The provider directory lists the clouds that rent comparable accelerators on demand. GPU cloud providers →

How does the Yunsui i20 compare with other accelerators?

This page sets the Yunsui i20 against the V100S. The Yunsui i20 is the newer generation of the two. This is a cross-vendor matchup, Enflame against NVIDIA, 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 Yunsui i20 figures come from?

Enflame published the Yunsui i20 figures in marketing material rather than a datasheet, and Flopper has no independent confirmation of them. How Flopper verifies specifications →

Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

The Yunsui i20 is the newer part: GCU / DTU 2.5 (2021) against the V100S's Volta (2020).

The V100S carries 16 GB more memory (32 GB against 16 GB), so larger models fit on one GPU before you shard. Bandwidth is 819 GB/s against 1.1 TB/s, which sets the ceiling on decode speed.

Power is 150 W against 250 W, and at FP32 the Yunsui i20 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 Yunsui i20 faster than the V100S?

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 Yunsui i20 or the V100S?

On raw FP16 throughput the Yunsui i20 and the V100S are level, so the decision rests on memory, power and price. Choose the V100S when the model has to fit on one GPU: it carries 16 GB more memory. The Yunsui i20 draws 100 W less power, which matters in an air-cooled or power-capped rack.

Which has more memory, the Yunsui i20 or the V100S?

The V100S carries 32 GB of memory versus 16 GB for the Yunsui i20. Memory bandwidth is 819 GB/s for the Yunsui i20 and 1.1 TB/s for the V100S.

How much power do the Yunsui i20 and the V100S draw?

The Yunsui i20 is rated at 150 W TDP and the V100S at 250 W. On FP32 throughput per watt, the Yunsui i20 is the more efficient part.

How much do the Yunsui i20 and the V100S cost to rent?

Live cloud listings tracked by Flopper price no live listings yet for the Yunsui i20, and the V100S from $0.88 per GPU-hour across 1 provider. The rental section on this page links to every provider, rate and the price history for each GPU.
