BRUSSELS (Reuters) - U.S. chipmaker Nvidia is set to win unconditional EU antitrust approval for its $6.8 billion (£5.30 billion) acquisition of Mellanox Technologies, people familiar with the matter said on Wednesday.

Nvidia, known for its powerful gaming graphics chips, is looking to boost its data center and artificial intelligence business via the takeover, its biggest deal, helping it to better compete with rival Intel.

The European Commission, which is scheduled to decide on the deal by Dec. 19, declined to comment. Nvidia and Mellanox also declined to comment.

U.S. authorities have already cleared the deal without conditions while approval is still pending in China where Mellanox has major customers such as Alibaba and Baidu .

Once known as a provider of gaming chips, Nvidia now also provides chips to speed up artificial intelligence tasks such as teaching servers to recognise images. Mellanox makes chips that connect those servers together inside the data center.

It beat Intel for Mellanox.
