IBM unveiled its most powerful computer.

The giant computer maker also revamped the rest of its 3090 series of big, mainframe machines. Some analysts said the new computers would force price cuts by IBM’s competitors. The biggest computer unveiled, the 3090 Model 600E, has six processors and up to 60% more power than the previous top of IBM’s line, the company said. Analysts estimated that it could execute 75 million to 80 million instructions per second, making it the most powerful commercially available computer.
