Intel
Thinking back to last year, Intel released some
juicy
morsels on its
Silverthorne (Atom) CPU during the International Solid State
Circuits Conference held in February.
This year, continuing the theme of major announcements at ISSCC, Intel
will be putting forward 16 papers, two more than last year, with the
eight-core Xeon chip taking centre stage.
Based on the proven, scalable Nehalem architecture, the octo-core,
16-thread-capable Xeon will, presumably, take all the other benefits
associated with the Nehalem line, including hyperthreading support,
integrated memory-controller, and QPI links to the system and other
processors in the box.
Weighing in at 2.3bn transistors, we reckon that the first batch of
eight-core Xeons will fit into a 2P server environment, with 4P EX
models to follow a little later on.
The move to octo-core processing, per CPU, was always going to happen in
2009, but it's a slight surprise to see it so early in the year.
Announcement and shipping product are two very different animals,
however.

I wonder how eight cores sharing that memory interface will hold up.
A hell of a lot faster than if they'd been communicating over FSB! The memory bandwidth for the triple channel IMC is huge and should be no bottleneck at all.Quote
is this a "true" 8-core, or is it two quads slapped together on one die, with the associated heat badness?Quote
but you do Breezey... you need 8 cores to just boot into windows! Honest.
Well the fact that Vistas defualt option uses 1 core only which is stupid so even people with dual and qaud cores arnt using them, i relise is mostly down to the HDD but still.Quote
