Rambus in Cell Processors and Intel's Dual Core Announcementsby Anand Lal Shimpi on February 7, 2005 3:09 PM EST

Intel’s Happy about Dual Core
While AMD has been touting dual core for quite some time, it’s looking like Intel will beat them to the punch - at least on the desktop. Intel had a couple of interesting announcements this morning as well.
The first thing they sent out to us was an interesting fact - that Intel has 11 multi-core projects that they’re working on for the 2005 - 2006 time period. Doing a quick number check we’re left with the following breakdown:
3 - “Smithfield” based Pentium 4 8xx series CPUs
1 - dual core Pentium 4 Extreme Edition
3 - “Yonah” based Pentium M CPUs (in 2006)
That leaves us with four unaccounted for chips - we’d expect Xeon and Itanium to fill in those blanks nicely.
Intel confirmed what we wrote about in our most recent roadmaps - the first dual core desktop CPUs will be arriving next quarter. Intel is going to be releasing two CPUs, one 90nm Extreme Edition and one 90nm Pentium 4 8xx model.
What’s interesting is that the 90nm dual core Pentium 4 Extreme Edition will feature Hyper Threading support, something that is left out of the regular Pentium 4 8xx series. A Hyper Threading enabled dual core Pentium 4 EE would mean 4 logical processors, capable of executing 4 simultaneous threads across the two physical cores. It looks like the EE chip will be launched with the new 955X chipset (Glenwood), with support for the 1066MHz FSB and DDR2-667 support. We often wondered why Intel wasn’t using the 1066MHz FSB with their Smithfield dual core processors, now we know - Intel’s saving the faster FSB for their price premium Extreme Edition part.
The Pentium 4 8xx CPU, which we’ve already talked about in great detail, won’t have Hyper Threading support and will use the 800MHz FSB. The 8xx series will run on either the 955X or on upcoming 945 based motherboards, but not on present 925/915 solutions.
The 90nm dual core solutions have just completed initial production runs and they should be ready to go by Q2.
Intel also announced that they have production samples of their first dual core 65nm CPUs - none other than Yonah (Jonah). Given the diligence of Intel’s Pentium M team in Israel, it’s no surprise to see a chip that’s supposed to be released at the beginning of next year already up and running in labs.
More info as we get it....
