May 21 (Reuters) - Amazon.com's ( AMZN ) cloud services

unit said on Tuesday that it has not halted any orders of

Nvidia's ( NVDA ) most advanced chip on the market, but has

instead decided to purchase the company's newer state of the art

chip for an upcoming supercomputer project between the

companies.

Earlier, the Financial Times had reported that Amazon Web

Services (AWS), the world's largest cloud services firm, had

"fully transitioned" its previous orders for Nvidia's ( NVDA ) Grace

Hopper chip to its newer Blackwell graphics processing units

(GPUs), that Nvidia ( NVDA ) announced in March.

An AWS spokesman told Reuters that the transition from Grace

Hopper chips to Blackwell chips applies only to Project Ceiba, a

supercomputer that AWS and Nvidia ( NVDA ) are building together. AWS

continues to offer other services based on Nvidia's ( NVDA ) Hopper

chips, its flagship model for training artificial intelligence

systems (AI), the spokesman said.

The Project Ceiba transition was announced by the two firms

in March when Nvidia ( NVDA ) unveiled the new Blackwell chips.

"To be clear, AWS did not halt any orders from Nvidia ( NVDA ). In

our close collaboration with Nvidia ( NVDA ), we jointly decided to move

Project Ceiba from Hopper to Blackwell GPUs, which offer a leap

forward in performance," an AWS spokesman said in statement.

The Financial Times amended its earlier story to say that

Amazon's ( AMZN ) chip orders had not yet been placed. The newspaper

directed a request for comment to its updated story.
