Timothy Prickett Morgan at The Register reports this week on news that Sun CEO Jonathan Schwartz is (publicly) confident that the company’s new Rock processor will finally appear this year. Sun confirmed in February of last year that the chip was being pushed to the second half of 2009, a delay of a year.
The Rock chips, which taped out two years ago, include several new technologies that Sun hopes will give it a competitive advantage in the midrange and high-end of the server market.
Among those technologies, the two biggies are scout threads for the Sparc cores and transactional memory, both of which aim to boost the performance of machines more than can clock speeds and execution threads alone. The Rock chips are expected to have 16 Sparc cores, each with two execution threads.
