I`m guessing you mean two dual core cpu and a quad core, but the expression
"2x2 and 1x4" is not often used because of the easy mix up, There`s lots of
Intel Dual Core, and you can run all of them on different Ghz..So its
impossible for me to give you a easy answer. I suggest you do a search on
your own on the website
http://www.intel.com/index.htm , in the up right
corner.
The design of the chip depends and what it is going to be used for, in a
standard pc,
it is often used with grapics card with pci express x16 and therefor has to
have an architecture for this connectivity as well as all the other known
connectivity standards for standards computers. I quess you get the idea.
You wanted the relase date for dual core cpu`s and i seem to find some
papers thats plans, the release of dual core in may, 2005. And as you now
the quad core has just been released. You have to give me more information
about exacly what chip for the accurate date and spesification and
designations of that chip.
The Intel® 3000 and 3010 chipsets are designed for use with Dual-Core
Intel® Xeon® 3000 Sequence, Intel® Pentium® 4 processor 600Sequence, Intel®
Pentium® D processor 800 Sequence and 900 Sequence, andIntel® Celeron® D, in
the LGA775 package in entry-level UP server platforms.The chipset contains
two components: Memory Controller Hub (MCH) and Intel®I/OController Hub 7
(ICH7). The MCH provides the interface to theprocessor, main memory, PCI
Express*, and the ICH7. The ICH7 is the seventhgeneration I/O Controller Hub
and provides a multitude of I/O relatedfunctions. Intel® 3000 chipset
supports one PCI Express x8 port. Intel®
3010 chipset supports two PCI Express x8 ports or one PCI Express x16 port.
PCI Express* I/O Interfaces supports 1 x8 with the Intel® 3000 chipset,
and2 x8, or 1 x16 with the Intel® 3010 chipsetThe Intel 3010 Chipset
supportsflexible I/O with 2x8 or 1x16 PCI Express, and the Intel 3000
Chipsetprovides a single PCI Express I/O x8 port . Also provides
configurable Intel® I/O Controller Hub (ICH7R) 1x4/2x1 PCI Express ports to
meet higherI/O server demands. Multiple interfaces eliminates the need for
bridge solutions and reduces server bottlenecks.
