Select processors from Advanced Micro Devices do not support Windows 7 "XP mode" though, like Intel, the vast majority of shipping processors do support XP mode.
Microsoft describes XP mode on its Web site as follows: "As part of the upcoming Windows 7 Release Candidate milestone, Microsoft will release a beta version of Windows XP Mode, which allows users of Windows 7 Professional and above to launch many older Windows XP productivity applications directly from their Windows 7 desktop. The Windows XP Mode stand-alone feature is specifically designed to help small businesses that are using Windows XP applications move to Windows 7. For larger businesses, Microsoft Enterprise Desktop Virtualization (MED-V) MED-V 2.0 builds on top of Windows Virtual PC and provides centralized management of Windows XP Mode. MED-V 2.0 will be available in beta within 90 days of general availability of Windows 7."
"All CPUs AMD is currently shipping, except Sempron, include AMD-V and therefore support XP mode," an AMD spokeswoman said Wednesday.
AMD also cited processors that are not necessarily shipping currently. "With the exceptions of Sempron-branded processors and Turion K8 Rev E processors, all notebook processors shipped by AMD include AMD-V and therefore support Windows 7 XP mode," AMD said. "With the exceptions of Sempron-branded processors and pre-Rev F Athlon branded processors, all of the desktop processors shipped by AMD include AMD-V and therefore support Windows 7 in XP mode."
And Opteron processors: "Also, all AMD Opteron processors shipped by AMD from Rev F forward include AMD-V," according to AMD.
A quick search on Best Buy's Web site turned up very-low-end systems that use the Sempron processor. For example, a $329.99 Acer desktop is currently being sold with a Sempron processor. And on Hewlett-Packard's Web site, an HP Compaq dx2450 Microtower (starting at $329), for example, can be configured with a number of different Sempron processors.
Dell has sold laptops, such as the Latitude D531, with AMD Mobile Sempron processors.
An earlier Nanotech: The Circuits Blog post cited Intel processors that do not support XP mode. Intel spokesman Nick Knupffer asserts this won't be a big issue. "Having VT (Virtualization Technology) on these consumer laptops is not going to be an issue--because the consumer versions of Windows 7 (Starter, Home Basic, and Home Premium) do not include Windows XP Mode," he writes.
Updated on May 6 at 6:35 p.m. PDT with additional comments from Intel.
A small brouhaha is erupting over Windows 7 and Intel processors. The hubbub is centered on which Intel processors will not support "XP mode" in Windows 7 and, by extension, which PCs will not support XP mode. Retail laptops may be one of the most prominent segments affected.

(Credit: Best Buy)What is XP Mode? Here's how Ina Fried of CNET News describes it: "XP mode consists of two things, the Windows Virtual PC engine and a licensed copy of Windows XP Service Pack 3 as a packaged virtual machine. Although neither piece will be included in the Windows 7 box, XP Mode will be a free download for those who have a license to Windows 7 Professional, Windows 7 Enterprise, or Windows 7 Ultimate."
XP Mode (XPM) is aimed at businesses that have Windows XP-specific applications that they need to run on Windows 7. XPM allows XP applications to run seamlessly on Windows 7, according to Microsoft. The catch: Intel processors must have Virtualization Technology, or "Intel VT," in order to run XPM. (I won't cover Advanced Micro Devices processors here but will address AMD in a later post.)
Ed Bott's Microsoft Report says that "some of the most popular PCs on the market today...won't be able to use the vaunted Windows XP mode in Windows 7."
Bott lists Intel desktop and mobile processors that will and will not support XP Mode here and here, respectively.
Intel mobile processors may be the most problematic in supporting XP mode; not because of the raw numbers--most newer Intel mobile processors do, in fact, support Intel Virtualization Technology--but because a disproportionate number of those that do not have VT (and therefore don't support XP mode) are laptops sold at retail. (And, undoubtedly, some small businesses purchase laptops at retail.)
In the Core 2 mobile camp, the P7350/7450, the T5200/5250/5270/5300/5450/5470 series, and the T6400/6570 do not support VT, according to Bott's blog. And this can be confirmed on Intel's Web site.
A quick glance at Best Buy shows a somewhat lengthy list of laptop SKUs (models) with, for instance, the T6400 (non-VT) processor. The list includes Dell Studio, Toshiba Satellite, HP Pavilion, Sony Vaio, Asus, and Gateway laptops.
In the $600 to $899 laptop range, I found about 30 different SKUs with T6400 processors, though it should be noted that some of these SKUs are simply models with slightly different configurations.
And a quick search on CNET Shopper turns up a number of consumer models with the T5270. The point? To state the obvious, consumers will have to verify which processor their laptop has.
In an Intel blog, Nick Knupffer asserts this won't be a big issue. "Having VT on these consumer laptops is not going to be an issue--because the consumer versions of Windows 7 (Starter, Home Basic, and Home Premium) do not include Windows XP Mode," he writes.
And Intel, in a statement, had this to say. "Intel introduced its Virtualization Technology in 2005 and has shipped over 100 Million chips with the feature. Windows XP Mode is targeted for business customers. It is available on the mid to higher end versions of Windows 7 and is supported in hardware by many Intel processors."
Intel continued: "Intel vPro technology PCs are required to have an Intel VT capable CPU and Intel VT capable BIOS. They are the best platforms for testing and deploying Microsoft Windows Virtual PC and Windows XP Mode."

Nvidia on Tuesday said it has signed a license agreement with Sony to provide PhysX technology for the PlayStation 3, whereby Nvidia becomes the official tools and middleware provider for Sony PS3.
Nvidia's PhysX technology--based on the laws of physics--enables game objects to respond in a realistic way to physical events. More conventional technology uses a canned response, in which the same response is repeated over and over.
For example, a window breaks, or a person falls the same way every time. In a PhysX-enabled football sports game, however, the angle and velocity of the impact is calculated by the graphics processor to generate a real-time response that is different practically every time.
The agreement with Sony Computer Entertainment covers tools and middleware for the PlayStation 3. Nvidia is now an official Tools and Middleware provider for Sony PS3, according to Bryan Del Rizzo, an Nvidia spokesman. "This new relationship means a couple of changes in how the PhysX SDK for PS3 is managed. As a Sony Computer Entertainment Tools and Middleware provider, Nvidia will now be exclusively responsible for maintaining and enhancing the PS3 PhysX SDK," he said.
Rizzo continued: "Additionally, while Sony has a license to distribute and support users of the binary version of the PhysX PS3 SDK, Nvidia will now be responsible for licensing the source code PhysX SDK for PS3 as well providing direct support to all source code-licensed PhysX PS3 developers," he said. "This newly announced tools and middleware relationship with Sony closely mirrors the licensing and support model that has existed for years with Microsoft and its Xbox 360 platform and complements our plans to support future console platforms."
Nvidia described the SDK as "a full-featured (application programming interface) and robust physics engine, designed to give developers, animators, level designers, and artists unprecedented creative control over character and object physical interactions by allowing them to author and preview physics effects in real time."
In December, Electronic Arts and Take-Two Interactive Software adopted Nvidia's PhysX technology.
Some laptops, especially ultraportables, brazenly push the envelope on pricing. In the age of the ultra-cheap Netbook, are they really worth the $2,000 to $3,000 price tag? I've listed three egregious offenders and two that fall into the less-scandalous-but-still-snooty pricing category.
HP Voodoo Envy 133 is a stunning design but way overpriced because of old hardware
(Credit: Hewlett-Packard)Let's start with the Hewlett-Packard Voodoo Envy 133, probably the most brazenly overpriced of the batch because it will still set you back as much as $2,700 despite the fact that it hasn't been updated in almost eight months and, accordingly, comes with obsolete hardware.
The 13-inch ultra-slim Voodoo Envy 133 model NV4050NA is priced at $2,699.99 (with "instant rebate"), but the buyer gets nothing extraordinary for this extraordinary price, with the possible exception of an external optical drive and a power adapter with a wireless access point built in.
The stratospheric-price-defying negatives include an old processor, a lagging-edge solid-state drive (64GB instead of the current 128GB standard), and last year's graphics.
Here's a quick rundown:
- An old Intel Core 2 Duo SP7700 Processor (1.8GHz) processor (think: original MacBook Air)
- A passé 64GB solid-state drive
- An ancient Intel graphics media accelerator X3100 (think: original ThinkPad X300)
- A short-lasting 3-cell battery
- An external optical drive (this is one of the few pluses)
The next criminally overpriced laptop is the 13-inch Sony Vaio Z Series ultraportable laptop (3.4 pounds). The VGN-Z590UBB model is priced at $3,899.99. Amazingly, this comes with only a one-year warranty.
Sony Vaio Z series is aimed presumably at Wall Street firms flush with stimulus-package cash
(Credit: Sony)But first a few positives. One of the most unusual features of the Vaio Z is a discrete Nvidia GeForce 9300M graphics chip. Almost all of the newer ultraportables come with Intel 4500MHD integrated graphics only. So this is certainly a plus and echoes the Nvidia 9400M graphics in the newest MacBook Air. It also packs DDR3 SDRAM memory. This is good too.
But there is little to justify (in my opinion) a price tag approaching $4,000 (unless Sony has doubled up on gold memory connectors and isn't telling us about it). Yes, you get new Intel silicon (a P9500 running at 2.53GHz), hybrid graphics (Nvidia and Intel), a high-resolution LED display (1600 x 900), but nothing that justifies forking over $3,900, even if you're Merrill Lynch flush with stimulus-package cash.
The third up is the 12-inch Fujitsu LifeBook B6230 (3.2 pounds), priced at $1,799. Though it's listed lower than the Voodoo and the Sony, the features are strikingly unimpressive for the $1,800 list price. An archaic Intel ULV U7600 (1.2 GHz) processor (533 MHz front-side bus), 1GB of memory, an 80GB hard disk drive, 802.11a/b/g wireless (no "n" here), and a one-year warranty round out (yawn) the features.
The price of Apple's MacBook Air is less egregious than the others but still exorbitant
(Credit: Apple)In descending order of extravagance, at No. 4 is the 12-inch Toshiba Portege R600 model S4202. Price aside, a quick glance at the features would impress most prospective buyers: very light at 2.4 pounds, standard 3GB of memory, a 128GB solid-state drive, a integrated optical drive, 802.11a/g/n wireless, and a Webcam.
What's the downside to these decent features? You guessed it, the price: $2,999--and that includes a slow Intel SU9400 (1.4GHz) processor. With full-featured Netbooks costing about one-sixth the price (between $500 and $700) and an HP Pavilion dv2 ultraportable on the way priced at about $900, the Toshiba begins to look, well, overpriced.
Finally, I must mention the Apple MacBook Air (I know I'll get slammed for this). The newest version with the upgraded Intel processor, Nvidia graphics, and a 128GB solid-state drive is certainly a vast improvement over the original. But in the age of the Netbook and seriously budget-constrained buyers $2,500 ($2,499) is just too expensive.
Apple needs to bring the high-end MBA down to about $2,000. Still pricey but probably justifiable (to the lucky few out there who sold their Nantucket vacation home before the crash).
Note: This is not a CNET review. This reflects the opinion of Nanotech: The Circuits blog only.
Here's the silicon scuttlebutt of the weekend, if not the week: Sony will use Intel's Larrabee graphics chip in its upcoming PlayStation 4. (Let's not forget the other tantalizing piece of speculation this week: the Nvidia-powered Microsoft smartphone rumor, which Microsoft apparently put to rest.)
We know for a fact that Jeffery Katzenberg at DreamWorks likes Larrabee--a lot. That apparently was one of the reasons DreamWorks dropped Advanced Micro Devices.
So, chalk that up as one big win for Intel's somewhat-murky next-generation graphics chip due late this year or 2010. Now Sony? A report this week in the U.K.-based technology Web site The Inquirer claims Sony favors Larrabee over Nvidia for its PlayStation 4. (The other major piece of silicon used in the current PlayStation is a Cell processor developed jointly by IBM, Sony, and Toshiba.)
For the record, an Intel spokesperson said the company "cannot comment on rumor or speculation." Sony in Europe reportedly didn't mince words, however, comparing the report to some of the 20th century's great fiction. Though another reported comment from Sony is more insipid and PR-like.
The U.K. report claims Intel paid to play. The report also hinges on the premise that Sony doesn't like Nvidia anymore. (And claims there are others that feel the same way about Nvidia.) Even if there is some special hatred there (as the reporter claims), that's not news--and applies to just about any acrimony-ridden hardware relationship in Silicon Valley. (Just peruse some of the tender exchanges between Intel and Microsoft in court records over the years.)
Anti-Nvidia bias (which is palpable in the report) aside, if there is a broader truth to this, that is, that game box makers are considering Larrabee, the chip would become a serious contender and take its place with GPUs from Nvidia and AMD's ATI graphics unit. But we won't know this for a while since no one (that I know of) has actually put Larrabee through the paces (though DreamWorks has hinted at this). And the PlayStation 4 isn't due, reportedly, until 2012.
Intel will bring out a new Core-architecture processor for lower-cost ultra-thin laptops later this year, according to Intel sources at the Consumer Electronics Show in Las Vegas.
22-millimeter packaging used in the MacBook Air
(Credit: Intel)The processors will distinguish themselves by targeting a price segment below pricey ultra-portables, which typically start at around $1,500 and range all the way up to $3,000--and higher in some cases. The processors will not compete with the Atom processor that powers Netbooks, which usually top out at $500.
In this sense, the new chips will be comparable to Advanced Micro Devices' recently announced Athlon Neo processor for ultra-thin laptops priced between $700 and $900.
The processor is "going to enable notebooks that are less than one inch (25mm)," according to the sources. The architecture will be a "tweak" of Intel's existing ULV (Ultra-Low-Voltage) processors, said the sources.
Current ULV Core 2 Duo mobile processors, such as the SU9300 and SU9400, have a power envelope (Thermal Design Power or TDP) of 10 watts, much lower than standard Intel mobile Core 2 Duo processors that have a TDP of between 25W and 35W.
ULV processors are used, for example, in ultraportables such as the Toshiba Portege R600 and Sony Vaio TT. Both are ultrathin high-priced boutique ultra-portables, starting at about $2,000.
Intel also offers SL series low-power mobile Core processors with a TDP of 17 watts.
The package size of the new processors will be 22 millimeters by 22 millimeters, according to the sources.
LAS VEGAS--If you haven't noticed, Toshiba doesn't offer a Netbook for the U.S. market.
Yes, that's right Toshiba--whose name is practically synonymous with laptops--is still undecided about committing to one of the hottest mobile PC markets in the U.S., according to Toshiba officials at the Consumer Electronics Show in Las Vegas on Thursday.
The Japanese company did launch the NB100 Netbook in December, but it is not marketed in the U.S., according to a Toshiba representative, speaking at CES.
Toshiba NB100 Netbook is marketed in Latin America
(Credit: Brooke Crothers)This highlights the Netbook quandary some of the largest mobile computer markers are facing. Throw Sony into the we don't-offer-a-Netbook-either category. This week Sony launched the pricey Vaio Lifestyle PC that it is very careful to bill as the "world's lightest 8-inch notebook." It costs a cool $900--which does tend to disqualify it as Netbook since Netbooks are, by definition, inexpensive (typically under $400 and only occasionally venturing into $600 or $700 territory when, for example, a 3G Wireless Wide Area Network, or WWAN, option is added.)
Listening to a Toshiba representative at CES, the company seems genuinely perplexed by the Netbook category. Where is the real value-add? What if Netbooks begin eating into its notebook line?
On the latter point, Toshiba, like Sony and Apple, may also be worried about getting consumers hooked on low-cost laptops.
(Note: The Toshiba NB100 is marketed in Latin America, according to the representative.)
The Gateway notebook roll-out is official. Sony's is not. Gateway Computer announced three lines of notebook PCs on Monday with 64-bit Windows, while Circuit City prematurely posted images of upcoming Sony notebooks.
Gateway 14-inch T6836
(Credit: Gateway )Gateway rolled out three notebooks targeted at students. The P series desktop replacement comes with a 17-inch widescreen, the M series with a 15.4-inch screen, and the T series uses a 14.1-inch screen.
All systems come with 64-bit Windows Vista Home Premium and pack 4GB of memory--the minimum for acceptable performance in 64-bit Windows.
(See Gateway goes all 64-bit in back-to-school desktops.)
The 15-inch "Garnet Red" Gateway M-6848 is spec'd with an Intel Core 2 Duo T5750 processor, 4GB of memory, a 250GB hard disk drive, 802.11a/b/g,a wireless, DVD-R/RW drive, and Vista Home Premium 64-bit with SP1. It retails for $799.99.
The 14-inch "Pacific Blue" Gateway T-6836 notebook has virtually the same specifications. It also retails for $799.99.
Other features include a multimedia panel integrated into the keyboard, DVD burner with LabelFlash technology, and an integrated Webcam.
Upcoming Sony retail notebook
Meanwhile, details about upcoming Sony notebooks continue to seep out.
Circuit City prematurely posted photos of the upcoming Sony portables. (Though Circuit City has pulled the links, cached images are still accessible.)
Last week, less colorful user-manual images appeared at Notebookreview.com as well as tidbits about various models. Apparently, models will use Intel's next-generation Centrino 2 "Montevina" processor, graphics chips from Advance Micro Devices' ATI unit, and sport 13- and 16-inch screens.
Sony is set to refresh its notebook lineup with upcoming mobile chips from Intel. Specifications posted on some reseller sites and leaked in Sony documents show a major refresh potentially in the offing.
Sony Vaio laptop
(Credit: Sony)This may be good news for Advanced Micro Devices, too: its mobile graphics processors look to figure prominently in the new lineup.
A post on Laptoping says some model will come with 16.4-inch screens. Other models include ultraportables "featuring a 13.1-inch screen," Laptoping said. This series, as well as other Sony notebooks, will have a High Definition Multimedia Interface (HDMI).
One reseller lists a Sony Vaio VGN-FW198U/H laptop with a 2.53GHz Intel Core 2 Duo T9400 processor, 4GB of memory, a 320GB hard disk drive, and a Blu-Ray disc drive. A price of $2,149.99 is given.
The T9400 is not yet listed on Intel's processor pricing page, but logically slots in below the T9500 (2.6GHz) listed at $530.
This document posted on notebookreview.com shows a VGN-FW100 series image. One model (Vaio VGN-FW160E/H) posted on notebookreview.com is spec'd with a 2.26GHz Core 2 Duo P8400, 4GB of memory, a 250GB hard disk drive, and Blu-Ray Disc drive.
The P8400 is part of the P series of upcoming Intel processors that uses less power than current mainstream mobile processors.
The Vaio FW series is expected to pack AMD-ATI HD 3470 graphics as well as other graphics processors.
A consumer notebook line with 13.3-inch LED backlit LCD is also cited with an ATI Mobility Radeon HD 3470 graphics chip on various sites. Models listed here specify an Intel Core 2 Duo P8400.
Sony said it would not comment on speculation.
Dupont and Dainippon Screen Manufacturing will form a strategic alliance to develop mass production techniques for organic light emitting diode (OLED) displays, according to an announcement made in Japan.
Sony OLED display
(Credit: CNET)The focus is on developing better processes and printing equipment for the fabrication of OLED displays.
OLEDs are attracting interest because the panels are paper thin but offer extremely high-quality images, superb color saturation, and fast response times. And they draw little power because they don't require a backlight.
At the same time, they face durability challenges. The organic matter used to illuminate the image can by ruined by the elements, so special sealing technology is necessary. Also, a new study by DisplaySearch found that the brightness on Sony's 11-inch XEL-1 TV began to degrade significantly after 1,000 hours.
That's not all. OLEDs face size constraints. Many of the widely-used, mass-market OLEDs used today are only between and three and four inches diagonally. Sony's XEL-1, one of the largest, is only 11 inches but is priced at close to $2,000.
Dupont and Dainippon hope to solve the size problem and bring down the cost in the process. Their goal is to develop printing equipment that that will enable the production of very large OLEDs that would rival the largest LCD TVs in size.
DuPont brings its small molecule-based OLED solution materials and process technology to the table, while Dainippon Screen has developed a nozzle printing technology.
