News For May 2004Intel's Dothan Makes Its Late Debut
(May 10, 2004)
Intel's CEO Craig Barrett had already announced Intel's plans to launch the Dothan in early 2003. Touted as the next-generation Banias mobile processor based on the Pentium-M core, Barrett said it would launch the device at the end of 2003. In August 2003, the rumors began to circulate. Dothan CPUs would not see delivery until mid-February 2004, some said. Finally, in January 2004, Intel officially postponed the device's launch until to Q2. Intel attributed the delay to sample stepping, which meant there were difficulties for mass production. Thus, a new CPU stepping was required - at least that's what we're supposed to believe.
Perhaps another reason was that OEMs still had too many of the "old" Banias and Pentium 4M CPUs in stock, which led Intel to delay Dothan for tactical reasons. Who knows for sure?
Whatever the case, Dothan is here, which represents Intel's first mobile CPU based on its 90-nm process. We look at the CPU's features and how it matches up with its predecessor, Banias. In order to make a comparison between Banias and Dothan, we chose to use the Winbook W series notebook. (ztj051004)

INTEL wipes the slate clean, next-gen CPUs to be based on Pentium M
(May 7, 2004)
Intel plans to announce on Friday that it has shelved its next line of chips based on the Pentium 4 architecture for desktop and server computers. The chips reported to be history include Intel's fourth-generation Pentium 4 code-named Tejas, which was to be launched Q2 - 2005. Also, a new Xeon processor based on the architecture of Tejas for low-end computer servers code-named Jayhawk has also been cancelled.
Both chips represented what was to have been the next generation of 90nm Pentium 4 and Xeon, respectively.
According to Reuters, Tejas and Jayhawk are now history. The chip giant has decided to accelerate plans to roll-out desktop processors derived from its Pentium M architecture. Intel's Pentium-M mobile processor runs at less than two gigahertz, or billions of cycles per second, but has the performance of a desktop processor running at significantly faster speeds (3-4 GHz).
This is a clear departure from Intel’s Gigahertz frenzy of the past few years. The Pentium M, which is more like AMD’s Athlon XP processor architecture, offers better performance per clock cycle as compared to the current Pentium 4 processor architecture. Intel had recently announced that they will be changing their CPU naming scheme to reflect the performance more accurately.
Intel has decided to move forward towards a dual-core architecture, and rumors are abound that the next generation desktop and server CPUs are going to be based on a dual-core Pentium M architecture.
The reason for this move is believed to be the rising heat levels and power consumption of Intel’s P4 line of CPUs, aggravated by the recent introduction of the Prescott (90nm) CPUs. The Pentium M, which was developed for low-power CPU applications in laptops runs far cooler, and consumes significantly less power, while offering comparable performance.
In fact, an already announced chip codenamed Whitefield (which Intel India claims, is a 100% Designed in India product) is a low-power quad-core Xeon processor based on the existing Pentium M cores. The Desktop CPUs hence are expected to be dual-core versions of the same, or integrate the upcoming “Dothan” core. (ztj051004)

AMD Opteron 250 to launch on May 18th
Some of our server chips are discontinued
(May 8, 2004)
RELIABLE SOURCES SAID AMD is expected to introduce the Opteron 250 on the 18th of May.
At the same time, the recent price cuts reported on the INQUIRER also mean some changes to the AMD server line up.
The Athlon MP 2200 and 2400 are now discontinued, while the only chips to be had are the 2600 and the 2800.
System integrators are also a little miffed that AMD's Opteron 84X series are still only available in a tray version with one year warranty, and it's impossible to get boxed three year warranty parts.
AMD is performing a neat little trick to produce low power Opteron chips, we also learn. The firm grades 248 Opterons and test them for power consumption. The best of the bunch are downclocked to 1.4GHz and sold as low power 30W units, but at 248 prices, while the 1.4GHz category means they're really equivalent to Opteron 240s. The next best of the bunch are clocked to 1.6GHz and sold as 55 watt parts, although they're really equivalent to 242 parts.
We learned during the week at Barcelona that it's still going to be a while before we'll see 90 nanometre Opterons in any quantity. One source close to AMD said it is doing just as well moving to 90 nanometre processes as Intel. That implies Intel isn't doing quite as well as it could be. Or maybe it implies Intel is doing very well at 90 nanometres, and so it is too. (ztj050904)

AMD Fuels New Mobile Processors With 64-Bit Performance For Sleek Notebooks
Acer Inc. to Offer Racy New Ferrari Notebook with Extra 'Horsepower' Under the Hood
(May 6, 2004)
AMD (NYSE: AMD) today introduced two new low-power mobile processors designed to offer outstanding computing performance and true mobility for thin and light notebooks. The new low-power mobile AMD Athlon 64 processor models 2800+ and 2700+ further expand the award-winning AMD Athlon 64 processor family, offering a powerful 32-bit computing experience today with a seamless transition to 64-bit applications. These processors also offer an Enhanced Virus Protection security feature, to be enabled by the upcoming Microsoft Windows?XP Service Pack 2.
"AMD was the first to combine high-performance 32-bit computing with a 64-bit turbocharger in your backpack and on your desk. Now, thinner and lighter notebooks can be fueled with this same cutting-edge performance plus security enhancements to be enabled by the upcoming Windows XP SP2," said Marty Seyer, vice president and general manager, Microprocessor Business Unit, AMD. "We're bringing customers peace of mind by helping them protect their data and their PC investment."
Like all the existing AMD mobile processors, these new low-power offerings enable an outstanding computing experience on the go with extended system battery life enabled by AMD PowerNow! technology, as well as the benefit of wireless compatibility with today's most popular wireless solutions.
Global PC vendor Acer Inc. is among the first suppliers to support the use of low-power mobile AMD Athlon 64 processors in a new Ferrari brand thin and light notebook for consumers and business customers worldwide.
Likewise, Chinese manufacturer Amoi Electronics Company, Ltd. is incorporating the low-power mobile AMD Athlon 64 processor in a notebook.
"As the first China OEM to announce development of a low-power mobile AMD Athlon 64 processor-based notebook, we expect to bring real benefits to our customers. The Amoi Va series will be equipped with the latest high-performance processor, as well as a widescreen display in an attractive slim-and-wide form factor," said Yale Guan, general manager of Amoi's Information Technology Group. "These benefits combine to provide mobile users with an exceptional, portable computing experience."
Thin and light notebooks will be available from Acer in May, while Amoi expects to offer the new Va series notebooks during the second half of this year.
The new low-power mobile AMD Athlon 64 processor models 2800+ and 2700+ are available immediately worldwide for thin and light mobile PCs. (zjt050604)

Intel to Divide Processors By Power Consumption
LGA775 Products to Get Additional Markings
(May 5, 2004)
In an attempt to let the customers choose between processors with different heat-dissipation and power consumption, Intel will add a special marking on its chips in LGA775 packaging.
All boxed versions of Intel's new Pentium 4 and Celeron-D processors for the Socket T infrastructure will sport the so-called “Platform Compatibility Guide?code that will tell whether the chip can dissipate 84W or 115W, sources with knowledge of the matter said. Initially only boxed processors will have this code printed on the boxes, but eventually Intel plans to put the mark on the IHS of all chips in LGA775 packaging.
Platform Compatibility Guide 04A (PGC 04A) will be intended for mainstream and value processors, such as Celeron D and some Pentium 4 chips at $278 price-point or below. Processors that correspond to PGC 04A should have TDP of 84W or below.
Platform Compatibility Guide 04B (PGC 04B) will be intended for all Intel processors, including high-end, mainstream and value processor. Processors that correspond to PGC 04A should have TDP of 115W or below.
Processors that consume a lot of energy not only dissipate more heat, but also stress components of mainboards. As a result, loads of customers would like to install less power-hungry chips into their desktops so that to use quieter coolers and not get expensive mainboards that have specially-designed CPU power circuitries for processors that devour loads of power.
As reported numerous times, because of certain issues with Intel's 90nm fabrication process, actual chips made using it heat pretty well presumably as a result of power leakage processes. Power leakage is current flowing in a circuitry that is not being used at the moment. While the problem has been around for decades, it became dramatically serious with Intel’s Pentium 4 E processors known as Prescott.
Starting from the second quarter of 2004 Intel Corporation will mark its CPUs according to their position in its product family or series. The first digit in the model number reflects product positioning; another two digits reveal relative performance within a concrete family of chips. The rating will make pretty tough to compare microprocessors of different series by their working frequency, but is supposed to reveal clear processor’s place in its family.
Officials from Intel did not comment on the story. (zjt050604)
