Soon we can expect Xeon processors with a 1066MHz and next year Intel will debut its first Xeon processors with a 133MHz FSB.
Jason Waxman, director of server platforms group at Intel Corp., recently announced that the company’s code-named Woodcrest processor, which is a successor of Intel’s Xeon DP chip produced using 65nm code-named Dempsey, will have 1333MHz processor system bus and core-logic to support the chip will be able to handle two of such busses. Such technology is called dual independent bus (DIB) and is also to be supported on Intel’s code-named Blackford chipset that will be able to work with two dual-core Dempsey processors using independent PSBs.
Intel’s code-named Woodcrest dual-core processors are slated to be shipped in the second half of 2006, according to Intel’s roadmap.
Read on over here. It's also likely some desktop processors will start featuring the 1333MHz next year.
