14 DAY TRIAL // Intel used 800 MHz processor system bus (PSB) for years, but now is expected to update this feature for server chips, to bring it up to 1066MHz and 1333MHz next year.
Intel officials have recently announced that the company's code named Woodcrest processors, a successor of Intel's Xeon DP chip. This one is produced using the 64 nm (nanometer) process that is codenamed Dempsey. The new processors will have a 1333MHz processor system bus and core-logic to support the chip will be able to handle two of such buses.
This technology is called DIB (dual independent bus) and will be supported in Intel's code-named Blackford chipset, being able to work with two dual core Demsey processors that use independent PSBs.
Earlier this year Intel, confirmed that the processors codenamed Merom, Conroe and Woodcrest would not be based on the NetBurst architecture. This architecture powers the current Intel Pentium 4 and Xeon chips. The chips will also have capabilities like virtualization, 64-bit capability in addition to EDB, EIST and iAMT2. Also, the new architecture will have shorter pipeline and high performance per clock.
Intel's Woodcrest dual core processors are said to be shipped after the second half of 2006.
