The folks at The Register have gotten their hands on Sun's confidential roadmap from June, which outlines the company's plans for SPARC product lines. The chart has some basic technical details for the UltraSPARC T-series and the SPARC64 line. The long-anticipated "Rock" line is not mentioned. "We can expect a goosed SPARC64-VII+ chip any day now, which will run at 2.88 GHz and which will be a four-core, eight-threaded chip like its 'Jupiter' predecessor. This Jupiter+ chip is implemented in the same 65 nanometer process as the Jupiter chip was, and it is made by Fujitsu, a company that is in the process of outsourcing its chip manufacturing to Taiwan Semiconductor Manufacturing Corp. ... not only has Sun cut back on the threads with [the 2010 UltraSPARC model, codenamed Rainbow Falls], it has also cut back on the socket count, keeping it at the same four sockets used by the T5440 server. And instead of hitting something close to 2 GHz as it should be able to do as it shifts from a 65 nanometer to a 45 nanometer process in the middle of 2010, Sun is only telling customers that it can boost clock speeds to 1.67 GHz with Rainbow Falls."
