AMD Dual-Core desktop processor details revealed - Hexus
"The flagship
AMD Athlon 64 X2 4800+ will have both its cores operating at 2.4GHz, the same frequency as the AMD Athlon 64 4000+, and we'll be surprised if this doesn't rape the already impressive Pentium Extreme Edition 840"

Red Hat tests dual-core support - CNET
"Dual-core processors combine two processing engines onto a single slice of silicon, a prevailing method of squeezing more performance out of a processor. Red Hat told customers Friday that the beta version of the first update to RHEL 4 includes support for both AMD's and Intel's dual-core processors. "

AMD Nips Intel at the Core - The Street
"AMD and Intel's dual-core chips are also different in how they are built.
AMD's Opteron was designed from the ground up to evolve from a single core to multiple cores. The Pentium evolution was expected to continue in a single-core format for several more years. As such, AMD says data flow better between its cores because of a feature it calls its Direct Connect architecture."

AMD's dual-core Opteron due this month - CNET
"AMD will announce at an event on April 21 in New York that the first dual-core
Opteron processors are available, months ahead of schedule, sources familiar with the situation said. The Sunnyvale-based chipmaker also is expected to announce its dual-core chips for PC will go on sale in June."

Dual Core Athlon 64 Preview - HW Upgrade

Intel banks on new architecture - Investors
"Dual core does add one additional barrier, but it's not on the Intel side of the fence. For dual core to have any serious performance impact all the software compilers have to be modified to take advantage of the chip. Old code on the dual core computer will not fully benefit from the architecture. And, of course, AMD is working on its own version of the same idea. Intel expects that the majority of chips sold in 2006 will be dual core."

AMD Demos Dual-Core Athlon 64 - VAR Business
"The dual-core
Athlon 64 runs at a clock-speed of 2.4 GHz and has a maximum power dissipation of 100W. "We're in production," says Teresa deOnis, AMD's manager of branding. "We will have availability in the second half of 2005--that's when it will be in PCs on store shelves and in the hands of system builders.""

AMD Dual-Core Demonstrations Get Two Thumbs up at LinuxWorld
AMD today again displayed the strength of the AMD64 dual-core ecosystem with four dual-core AMD
Opteron processor technology demonstrations on existing partner server and workstation platforms at LinuxWorld Boston.  Demonstrated systems include a Cray XD1 supercomputer; the HP xw9300 Workstation powered by two dual-core AMD Opteron processors along with NVIDIA SLI dual PCI Express technology; the record-breaking HP ProLiant DL585 using four dual-core processors; and a Sun Fire V40z server powered by four dual-core AMD Opteron processors.

Intel Begins Multi-Core Silicon Production, Dual-Core Chipset to Intro in Q2 - Electronic Business
"The Santa Clara, Calif.-based chip giant also said it would deliver two separate dual-core products and dual-core-enabled chipsets for its Pentium processor-class families in Q2, including the Pentium processor extreme edition, which is to include hyper-threading (HT) technology, aimed at allowing four software “threads” to be processed simultaneously."

Intel expects twins in the second quarter - CNET
"The chipmaker said Monday that it will launch a pair of dual-core processors for high-end desktops during the second quarter. In doing so, Intel narrowed the time frame for when its first dual-core chip will be available to consumers and businesses. Previously, the company had said only that it would be available in 2005."

AMD to launch dual-core Toledo to counter the Intel Smithfield - DigiTimes
"A number of vendors, including Hewlett-Packard (HP), Acer, Fujitsu Siemens, Sony and Gateway, have decided to incorporate the Toledo in their desktops, the sources noted. AMD is now entering the competition with both single and dual-core desktop processors, and the company will continue in 2006 with a dual-core processor codenamed Windsor, to counter Intel’s Presler, the sources noted."

AMD to keep dual-core processors in current 90nm power envelope - THG
"AMD provided first bits on power usage of its upcoming dual-core Opterons last October. System builders now received confirmation that the new processors will stay within the power consumption range of current
90 nm processors"

Intel's Dempsey dual core CPU to Glidewell down Greencreek - the inquirer
"Intel hasn't decided what speeds Paxville and Dempsey will clock at yet, but it has a 3.33GHz 8MB Potomac with a 667MHz front side bus ready to launch. There will also be a 3GHz Potomac, and a 2.83GHz Potomac with only 4MB of cache"

Intel's dual-core CPUs to set new record high in power consumption - THG
"Intel's upcoming dual-core processors once again will test the limits of power consumption. According to documents seen by Tom's Hardware Guide, the Smithfield CPUs are rated at a thermal design power of 130 watts, an increase of 13 percent from today's
Prescott processors"

01/10/05 Intel reveals dual-core plans - vnu net
"Intel's first dual-core chip is likely to be Smithfield, a desktop processor also due by the middle of this year, but which could ship as early as Q1according to some reports. Montecito, a dual-core version of Intel's Itanium 64bit chips for high-end servers, is due to ship to vendors in the second half of 2005. Dual-core Xeons are set to ship in the first quarter of 2006 for dual-processor and multi-processor systems.

Taiwan server makers quick to test new dual-core Opteron samples - DigiTimes
"Tyan is expected to announce an 8-way
Opteron-based server at CeBIT or Computex in 2005, said the sources. This server board would likely be based on a chipset from ServerWorks, a Broadcom subsidiary, according to the sources."

Dual core Opteron speeds, power revealed - the inquirer
"AMD has already sampled some dual core chips to a select few of its customers.
HP is a favoured case in example, but some members of the X64-32 coding community are believed to have samples as well."

One Core Is Good. Two Cores Are Even Better! - X-bit labs
"Both cores of AMD’s dual-core CPUs will feature completely independent execution units and cache memory. In other words, each of the two cores within a single processor from AMD will have its own L2 cache, so the company engineers will have to pay special attention to their coherency. However, I don’t think this is going to become a really serious problem for AMD: MOESI protocol (Modified, Owned, Exclusive, Shared, Invalid) developed in the times of AMD Athlon MP processors can pretty much guarantee proper cache memory coherency not only for different CPUs of an SMP system, but also for different processor cores"

Core blimey - Making the move to dual-core computing - PC World
"While the 64-bit Montecito Itanium with its 1.7 billion transistors and 24MB cache isn’t likely to end up in the sort of boxes you and I will have, Intel intends to add dual cores to the 32-bit Pentium 4 processors. These will have HyperThreading as well, so the CPUs should be able to handle four threads at the same time. Availability is anyone’s guess, but the money’s on dual-core Pentium 4s coming out in a year’s time, in both desktop and mobile configurations, perhaps in
65nm process technology"

AMD tips 'Pacifica' and 'Presidio' processors for '06 - EE Times
"Weber did not disclose the details of "Pacifica" and "Presidio." The technologies are expected to follow the company's initial dual-core design, which is said to be launched in 2005"

Intel pushes out dual-core Itaniums, or does it? - Computer Business
"To hear the top brass at Intel talk about it, everything is fine and dandy in Itanium land. The fact that the dual-core 'Montecito' Itanium processors have been pushed out to a volume ramp up in the first half of 2006 is not only not a problem, they say it was the plan all along. Timothy Prickett Morgan investigates..."

VMWare Touts New Virtual Server Software Skills - Tech Web
"The feature, dubbed "4-Way VMware Virtual SMP" (for symmetric multiprocessing), will release in the second half of 2005, and is a follow-up to the 2-Way SMP that the San Diego-based vendor released last year.  The 4-CPU version of this add-on to VMWare ESX Server, the company's flagship virtual machine software, anticipates the arrival of multi-core processors from both Intel and AMD, said one analyst."

Via's twin-core processor may upstage AMD, Intel - Next World Fusion
"Announced in May, the Esther cores are manufactured by IBM using a 90 nanometer process. The 32 bit chips consume 3.5 watts when running at a clock speed of 1 GHz and will run at a clock speed of up to 2 GHz. Esther also incorporates Via's PadLock security technology that offers hardware-accelerated RSA encryption and support for
NX (execution protection) anti-virus technology. "

Intel's Barrett: More to Life than Gigahertz - EWeek
"Yes. Everything moves off dual core—or multiple core—and multiple threads in the future. In addition, the architectures are designs that are the most power-efficient. What are the most power-efficient architectures today? Pentium M architecture's a hell of a lot more power-efficient than Prescott. So we're going to do two things: build off the most power-efficient capability and go to multiple cores and leave the speed game on the side."
