Huawei’s 910c is about 30% slower and 1/3 more expensive.
NVIDIA H100s are currently going for around $25k to Huawei's $28k. And that's before you get to the secondary market, where NVIDIA chipsets will inevitably jump in price based on availability and relative demand. Without Huawei in the market, I guarantee NVIDIA's chips would be even more expensive.
At some point, its just a matter of what is available. American tech companies are demanding more chipsets than NVIDIA can currently produce, which is why the company's still considered a growth investment play. Chinese competitors aren't going to be able to import NVIDIA to meet their own internal demand. They'll buy Huawei units because that's what is on the shelf.
